Which person has the most potential energy

Answer:

1.0 g per cubic centimeter.

Explanation:

Answer:

Density = (3.33kg or g)/cm³(since you didn't state the unit of the mass)

Explanation:

volume = length × breath × height

let's take it as,

length = 2.0cm

breath = 3.0 cm

height = 2.0 cm

mass = 40 kg or g (since you didn't state the unit of the mass)

volume = ?

volume = length × breath × height

volume = (2 × 3 × 2)cm

volume = 12 cm³

Density = mass /volume

40kg or g/12cm³

Density = (3.33kg or g)/cm³(since you didn't state the unit of the mass)

Answer:

chemical

Creatine Phosphate (with oxygen) So all muscle cells contain a high-energy compound called creatine phosphate which is broken down to make more ATP quickly. Creatine phosphate can supply the energy needs of a working muscle at a very high rate, but only for about 8–10 seconds.adenosine triphosphate (ATP)

The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body's biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells

Explanation:

Different sizes of ice cubes will result in different lengths of time in staying solid. A bigger ice cube will stay solid for longer than a smaller one.

Answer:

1) Gaining

2) More

3) More

4) increases

5) decreases

Explanation:

Nonmetals are found towards the right hand side of the periodic table. They form ions by gaining electrons due to the fact that they have more electrons in their outermost shell, hence they only need a few electrons to complete the octet structure.

As the number of shells increases, the outermost shell becomes more populated and easier to fill with electrons.

The reactivity of nonmetal elements generally increases from left to right across the periodic table but decreases from top to bottom down the group.

Answer:

1) Gaining

2) More

3) fewer

4) increases

5) decreases

Answer:

Chemical energy is the potential energy stored in the arrangement of atoms within molecules. Breaking chemical bonds requires energy, while forming new chemical bonds releases energy. The more energy that's released when a bond forms, the more stable that bond is.

Explanation:

there is only one sulphur (S) atoms in the formula for sodium sulphate

The chemical formula for sodium sulfate is Na₂SO₄.One sulfur atoms are in the formula for sodium sulfate.

The term chemical formula shows the elements that create  the compound and the numbers of atoms of each element in the smallest unit of that compound, be it a molecule or a formula unit.

Chemical formulas are classified into three types: empirical, molecular, and structural.

Empirical formulas depict the simplest whole-number ratio of atoms in a compound, whereas molecular formulas depict the number of each type of atom in a molecule and structural formulas depict how the atoms in a molecule are bonded to each other.

Thus, the chemical formula for sodium sulfate is Na₂SO₄. In sodium sulphate two molecules of sodium, one atom of sulfur, and four atoms of oxygen are present.

Answer:

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 10 g

volume = final volume of water - initial volume of water

volume = 52.1 - 50.7 = 1.4 mL

We have

[tex]density = \frac{10}{1.4} \\ = 7.142857...[/tex]

Answer:A

Explanation: because it represents a salt which is a nonmetal

Answer:

Explained below

Explanation:

In chemistry, the process of a chemical change is when the atoms from the reactants rearrange themselves and bond together differently to form one or more new substances with different characteristics than the reactants. Now, after this new substance is formed, the change is called a chemical change.

Now, in cooking Food will undergo a chemical change as it is being cooked. For example, when we boil brown meat, we are causing reactions that change the chemical composition in ways that enhance flavors. Proteins and fibers such as beans when cooked are broken down or undergo denaturation thereby making digestion easier when eaten. Fats like cooking oils are melted while Eggs when boiled are coagulated.

i think with exothermic reactions heat is released

this is what i looked up

hope this helps i took chem last year and think this is what i learned

Considering the definition of exothermic and endothermic reactions, the correct answer is second option: the reaction is endothermic.

Energy is the ability to do work or to produce heat.

Remembering that chemical reactions involve a reorganization of atoms between substances with breaking or formation of chemical bonds, this formation or breaking of chemical bonds is accompanied by changes in the energy of the system.

Chemical reactions that release heat are called exothermic. That is, an exothermic reaction is one where energy flows out of the system.

So, at room temperature, the heat released by a chemical reaction is enough to cause a rise in temperature.

An endothermic reaction is one that requires heat to take place. In other words, a chemical reaction is endothermic when it absorbs energy from the environment.

In this case, the heat is transferred from the outside to the inside of the system. By absorbing heat, the effect of an endothermic reaction is to lower the temperature.

When ammonium chloride is dissolved in water, the beaker gets cold. That means the system is absorbing heat from the surrounding and the temperature does down.

So, the correct answer is second option: the reaction is endothermic.

Answer:

Various compounds made of different forces between molecules

Explanation:

In an experiment, the independent variable is the variable that is changed or manipulated by the experimenter in order to effect a measurable response.

According to this question, a student compares the boiling point of substances having different intermolecular forces. This means that the student uses different substances with different intermolecular forces and measures the boiling point of each, which depends on the intermolecular forced in them. Hence, the independent variable in this experiment is the VARIOUS COMPOUNDS MADE OF DIFFERENT FORCES BETWEEN MOLECULES.
