Answer:

A chemical reaction is the process by which a change takes place

Explanation:

A chemical reaction is a process by which one or more substances, called reactants, are transformed into one or more other substances with different properties, called products.

The bonds between the atoms that make up the reactants are broken. Then, the atoms rearrange themselves in another way, forming new bonds and giving rise to one or more different substances from the initial ones. So the atoms do not change, they remain the same, but it changes is the way they are linked together.

In short, chemical reactions are the process of arranging atoms and bonds when chemicals come into contact. The chemical properties change by altering the arrangement of the atoms in that substance.

So, a chemical reaction is the process by which a change takes place.

In an isolated system, mass can neither be created or destroyed. ube FALSE TRUE

Marina86 [1]

Answer:

True

Explanation:

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

When the amount of oxygen is limited, carbon and oxygen react to form carbon monoxide. How many grams of CO can be formed from 3

Alinara [238K]

61.25 grams of CO can be formed from 35 grams of oxygen.

The molecular mass of oxygen is 16 gmol⁻¹

The molecular mass of carbon monoxide is 28 gmol⁻¹

Explanation:

The molar mass of carbon monoxide is molar mass of C added to that of O;

12 + 16 = 28

= 28g/mol

The molar mass of oxygen is 16 g/mol while that of oxygen gas (O₂) is 32 g/mol

Since the ration oxygen to carbon monoxide is 1: 2 moles, we begin to find out how many moles of carbon monoxide are formed by 35 g of oxygen;

35/32 * 2

= 70/32 moles

Then multiply by the molar mass of carbon monoxide;

70/32 * 28

= 61.25 g
