Answer:
No.
Explanation:
The reason for this is if everything in an ecosystem was a producer there would be nothing consuming and soon the ecosystem would be overwhelmed by two many products and nothing to consume them. A healthy ecosystem is a balanced cycle that makes sure everything is working properly and everything benefits something else. A food chain of sort is often seen in a balances ecosystem to show how everything is useful and needed. So in answer if there were only producers an ecosystem wouldn't thrive at its full potential, if at all.

Which statement describes a similarity between an apple and gasoline
Answer:
They both contain chemical energy, which people and cars convert into mechanical energy.
Explanation:
Answer:
B)They both contain chemical energy, which people and cars convert into electrical energy.
Explanation:
Which of the following has the most thermal energy?
A full-size candy bar that is melting
A swimming pool on a sunny day
The entire atmosphere of the earth
1 gallon of boiling water
The one that has the most thermal energy out of the following is 1 gallon of boiling water.
Thermal energy is the energy generated by a material as a result of particle movement inside the material. Thermal energy causes things to have an internal temperature, which may be measured. The greater the temperature measured, the quicker the particles travel within the system.
The full-size candy bar that is melting melts at a slower particle rate compared to the 1 gallon of boiling water whose particles travel faster.
A swimming pool on a sunny day has average thermal energy. Also, the entire atmosphere of the earth may not experience the same amount of thermal energy from the sunlight.
Therefore, we can conclude that the most thermal energy out of the following is 1 gallon of boiling water.

Each of these Ionic Compounds are named INCORRECTLY.
1. Find and describe the mistake
2. Correctly name the compound.
CaCl2 - Calcium Chlorine
CuS - Copper Sulfide
Li3P - Trilithium Phosphide
CuBr - Copper(II) Bromide
NaOH - Sodium Hydrogen Oxide
Explanation:
The nomenclature of ionic compounds is given by:
1. Positive is written first. And if the metal atom has various oxidation states then its oxidation state is to be mentioned in brackets with help of roman numbers
2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
1.) : Calcium chloride (Correct)
In the given compound, calcium has oxidation state of +2 and chlorine has oxidation state of -1.The name is correct.
2.) : Copper (II) oxide (Incorrect)
In the given compound,copper has the oxidation state of +1 and oxygen has oxidation state of -2.So ,the correct name will be Copper (I) oxide.
3.) : Lead (II) sulfide (Incorrect)
In the given compound, lead has the oxidation state of +4 and sulfur has oxidation state of -2. So ,the correct name will be Lead (IV) sulfide.

Suppose a high-flying jumbo jet with a mass of 45,000 kg cruises at constant velocity when the thrust of its engine is a constant 80,000 N. What is the acceleration of the jet?
Answer:
1.78 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{80000}{45000} = \frac{80}{45} \\ = 1.77777...[/tex]
We have the final answer as
1.78 m/s²Hope this helps you
what is formed when the number of electrons is changed?

physical changes : boiling water, freezing water, a pencil being sharpened.
chemical change : rotting cheese, exploding dynamite.
Answer:
boiling water
a pencil being sharpened
freezing water
Explanation:
A change that does not lead to any difference in chemical composition of a substance is known as a physical change.
For example, shape, size, mass, volume, density, boiling point, etc of a substance are all physical properties.
On the other hand, changes that lead to bring change in chemical composition of a substance is known as a chemical change.
For example, exploding dynamite, rotting cheese etc are all chemical changes.
Chemical change is the change in which there is rearrangement of atoms and the new substances get formed.
Boiling water only changes the phase from liquid to gas and thus is a physical change.
Pencil on being sharpened only gets smaller in size and thus is a physical change.
exploding dynamite would result into formation of new substances and hence a chemical change.
Freezing water only changes the phase from liquid to solid and thus is a physical change.
Rotting cheese would result in formation of new substances and hence a chemical change.
Therefore, we can conclude that following are the physical changes in matter.
boiling water.
a pencil being sharpened.

Based on electronegativity differences, which bond is a polar covalent bond?
Answer:
A bond in which the electronegativity difference between the atoms is between 0.4 and 1.7 is called a polar covalent bond.
A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal.
Which immunization is available to prevent communicable disease and illness?WILL MARK BRAINLIEST 30 PTS
bronchitis
diabetes
measles
strep throat
Measles is a communicable disease that requires immunization to prevent illness when exposed to it.
Measles is a communicable disease and highly contagious. It is usually very serious in children. The disease can be contacted through droplets in the air, physical contact and through mother-to-child transmission.
It is a very serious disease as it is caused by a virus which replicates very fast in the throat and nose thereby creating symptoms such as runny nose, coughing, sneezing and is usually accompanied with a rash.
The severity and death rates is what gave rise to the creating of a measles vaccine which is usually given to babies after birth to make them immune to the potential exposure to the virus.
Diabetes, bronchitis and strep throat have no vaccine as they can always be treated or managed with over-the-counter drugs.

Answer:
It is the length of these chains, and the patterns in which they are arrayed, that make polymers strong, lightweight, and flexible.
Explanation:
Synthetic polymers are made up of long chains of atoms, arranged in repeating units, often much longer than those found in nature. It is the length of these chains, and the patterns in which they are arrayed, that make polymers strong, lightweight, and flexible. In other words, it's what makes them so plastic.

If you weighed the atoms that appear on the reactant side of the equation, would they have the same mass as the atoms that appear on the product side?
Answer:
Yes,they will have the same mass.
Explanation:
According to law of conservation of mass:
'Mass can neither be destroyed nor be created during a chemical reaction'
In a balanced chemical reaction :
Total numbers of atoms on the reactants side are always equal to the total numbers of atoms on the product side.
Total mass of the atoms on the reactant side of the equation is always equal to the total mass of atoms on the product side.
For example:
Number of atoms on reactant side =
=(2)2 Hydrogen atoms + (1)2 Oxygen atoms = 6 atoms
Number of atoms on the product side =
=(2)((2 Hydrogen atoms) + (1 Oxygen atoms)) = 6 atoms
Mass of of reactants = (2)(number of hydrogen atoms)(mass of hydrogen atom) + (1)(number of oxygen atoms)(mass of oxygen atoms)
= (2)(2)(1u)+(1)(2)(16u) = 36u
Mass of products = 2((number of hydrogen atoms)(mass of hydrogen atom)+(number of oxygen atoms)(mass of oxygen atom))
= 2((2)(1u)+(1)(16u)) = 36u
Mass of of reactants = Mass of products = 36u
The nucleus’ pull on its electrons, taking into account any attractions weakened by shielding is called the:
Answer:
It's called the shielding effect
Explanation:
It describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. (I hope this helps)
The attraction pull of the nucleus on its electron weakened by the shielding of the inner shell electron is called the shielding effect.
What is the shielding effect?The shielding effect is the valence electrons are shielded from the attraction toward the nucleus of an atom. The shielding effect is the resistance offered by the inner shell electrons to the attraction of the valence electrons toward the nucleus.
This effect increases down the group in the periodic table as the atomic radii also increase and remains the same in the period. This effect is generated by the electrons present in the middle of the nucleus and valence electrons act as shields that repel those outer electrons.
Therefore, the effective nuclear charge acting on the valence electrons decreases. More shielding effect causes less electronegativity of an atom. The shielding effect describes how easily the electron can be removed from the atom making it more reactive.
