Answer:

The answer to your question is Stoichiometry

Explanation:

Stoichiometry is a very important branch of inorganic chemistry that is used to calculate the amount of reactants or products necessary in a chemical reaction so we can get the highest yield.

In stoichiometry, we must know the balanced chemical reaction and we can work with the mass in grams or moles.

Write a sentence that descrices how to determine the number of moles of a compound in known mass of a
sattari [20]

Explanation:

<u>Moles is denoted by given mass divided by the molecular mass ,  </u>

Hence ,  

n = w / m

n = moles ,  

w = given mass ,  

m = molecular mass .

For example ,

For  a compound X ,

The given mass i.e. w = 20 g

and the molecular mass ,i.e. , m = 10 g / mol

Then the moles can easily be calculated by using the above formula ,

n = w / m

n = 20 g / 10 g/mol = 2 mol

Hence , answer = 2 mol.

Vilka [71]

Answer:

An Omnivore

Explanation: An <u>omnivore</u> is a kind of animal that eats either other animals or plants. Some omnivores will hunt and eat their food, like carnivores, eating herbivores and other omnivores. Some others are scavengers and will eat dead matter. Many will eat eggs from other animals.

Omnivores eat plants, but not all kinds of plants. Unlike herbivores, omnivores can't digest some of the substances in grains or other plants that do not produce fruit. They can eat fruits and vegetables, though. Some of the insect omnivores in this simulation are pollinators, which are very important to the life cycle of some kinds of plants.

Balance the following chemical equation:<br> C2H60+02 → CO2 + H20
pantera1 [17]

Answer:

Explain: In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.
