Answer:

  •   The correct answer is B.

A physical change is a change from one state of matter to another; a chemical change results in a new substance formed.

<u><em>Physical properties:</em></u>

Physical properties are those which have same composition. In other words, composition does not change, only state may be change like solid to liquid, liquid to gas, solid to liquid etc.

<u><em>Example. </em></u>

Water when freezes into ice, it is physical change, just state is change.

<em><u>Chemical properties:</u></em>

The chemical properties depend upon composition.

<u>Example:</u>

Formation of precipitates is an example of chemical change.

damaskus [11]

Answer:

c.- How much of the reactants are needed and how much product will made.

Explanation:

The moles is the matter unit used in chemistry to simplify  some calculations, instead of using grams. Also the moles are very useful because the chemical reaction can be balanced.

When a Chemical reaction is balanced, then it can be easily to calculate how many moles are necessary to add in a process to obtain a quantity of grams of a product.

Amanda [17]

Cardenolides, with the chemical formula CH₁₈C₂₀H₁₅CHCO₂ have (D) 23 carbon atoms, 34 hydrogen atoms, and 2 oxygen atoms.

Milkweed contains a poison known as cardenolides. The chemical formula for cardenolides CH₁₈C₂₀H₁₅CHCO₂.

The subscripts in the formula represent the atomicities, that is the number of atoms of each element in each part of the formula.

We can calculate the total number of atoms of each element by adding its atomicities.

<h3>Carbon atoms</h3>

C =  1 + 20 + 1 + 1 = 23

<h3>Hydrogen atoms</h3>

H = 18 + 15 + 1 = 34

<h3>Oxygen atoms</h3>

O = 2
