A compound is a substance in which the atoms of two or more elements are chemically combined in a fixed proportion.
Answer:
A compound is a substance in which the atoms of two or more elements are chemically combined in a fixed proportion.
Explanation:
The correct answer is that a compound is a substance in which the atoms of two or more elements are chemically combined in a fixed proportion.
A compound is a substance composed of two or more kinds of atoms joined together in a definite grouping.
The properties of a compound are distinct and different from those of the individual elements that are combined in its make - up.
There are several millions of compounds known.
An element is a distinct substance that cannot be split-up into simpler substances. They are made up of only one kind of atom.

Which equation represents a conservation of atoms?
1.
2Fe + 202 → Fe2O3
2.
2Fe + 302 → Fe2O3
3.
4Fe + 202 → 2Fe2O3
4.
4Fe + 302 → 2Fe2O3
From the options, the reaction that shows the conservation of atoms is 4Fe + 302 → 2Fe2O3.
What is conservation of atoms?The idea of the conservation of atoms is that the number of atoms on the right hand side is equal to the number of atoms on the left hand side.
In this case, we have to a reaction equation which is balanced which is 4Fe + 302 → 2Fe2O3.

1. You are stirring a bowl of hot soup with a metal spoon. The spoon starts to feel warmer
A) conduction
B) convection
C) radiation
You are stirring a bowl of hot soup with a metal spoon. The spoon starts to feel warmer, this represents conduction.
What is conduction?One of the three primary methods for the transfer of heat energy is conduction. Radiation and convection are the other two methods through which heat is transferred. Heat energy is transferred through the mechanism of conduction when nearby atoms or molecules collide.
In liquids and solids where particles are more closely spaced, conduction happens more easily than in gases, wherein particles are more widely spaced. When there is a significant temperature differential between both the substances that are in contact, the rate of energy transfer through conduction is increased. You are stirring a bowl of hot soup with a metal spoon. The spoon starts to feel warmer, this represents conduction.
Therefore, the correct option is option A.

What is a compound?A material created by joining two or more distinct elements chemically in science.
A compound in chemistry is a material comprised of two or more separate chemical elements mixed together in a certain proportion.
Chemical connections that are challenging to break are created when the elements interact with one another.
2.5 mol of NaCl contains 5 moles of ions. This is due to the fact that 1 mol of NaCl contains 2 mol of ions, so you must multiply the molecular weight of the molecule by two to obtain the number of ions.
Thus, the answer is 5 moles.

What’s the meaning of low metabolism
Answer:
A person with a "low" (or slow) metabolism will burn fewer calories at rest and during activity and therefore has to eat less to avoid becoming overweight.
meaning of normal metabolism-Metabolism is the process by which your body converts what you eat and drink into energy. Even when you're at rest, your body needs energy for functions such as breathing, circulating blood and repairing cells. The energy your body uses for these basic functions is known as your basal metabolic rate.
A person with a low metabolism will burn fewer calories at rest and during activity and therefore has to eat less to avoid becoming overweight.
Signs of a slow metabolism
-You have gas.
-You crave sugar.
-You keep gaining weight.
-It's tough to lose weight.
-You always feel bloated.
-You have hypothyroidism.
-You easily develop cellulite.
-Your blood sugar is too high.

2.8 x 10-2 moles of NaCl
b
35.7 moles of NaCl
c
1.75 x 10-4 moles of NaCl
d
0.175 moles of NaCl
Given :
Volume of NaCl solution 2.5 L .
Molarity of NaCl solution is 0.070 M .
To Find :
How many moles are present in the solution.
Solution :
Let, n be the number of moles.
We know, molarity is given by :
[tex]M = \dfrac{n}{V(in\ L)}[/tex]
So,
[tex]n = M \times V\\\\n = 0.070\times 2.5 \\\\n = 0.175\ moles[/tex]
Therefore, number of moles of NaCl is 0.175 moles.

Click Oil Basics to explore the natural resources needed for the production of plastics. Use the information to answer the question. Which of these ingredients is important in making plastics? carbon dioxide particulate matter natural gas plant liquids volatile organic compounds
Answer:
natural gas plant liquids
Explanation:
The ingredients that are important for the production of plastics are natural gas and plant liquids. The correct options are c and d.
What is plastic?Polymers are the primary component of a wide variety of synthetic or semisynthetic materials known as plastics. Due to their versatility and importance to civilization, plastics are a very important material. This is due to the fact that plastics can be bent and molded into a variety of objects, from plates to phones.
Radiation is to blame for this becoming possible. People who manufacture plastics can heat polymers sufficiently to allow them to bend by employing radiation. They can then be formed into a variety of things when this occurs.
Plastics are made from natural gases and liquids obtained from plants.

3. Synthesis
Explanation:
Chemical reactions are of different types depending on how they occur. One of these types is called SYNTHESIS OR COMBINATION REACTION. A synthesis reaction is that reaction in which two atoms of two elements are chemically combined to form a single molecule or compound. That is;
A + B → AB.
This is the case in this question where atoms of Magnesium (Mg) and oxygen (O) reacted to form a single compound of Magnesium oxide (MgO). Hence, it is said to be a SYNTHESIS REACTION.
