Answer:

- 5.15×10²⁴ molecules of sulfur dioxide

- 3.63×10²³ molecules of carbon monoxide

- 6.02×10²³ molecules of ammonia

Explanation:

We begin from the relation that 1 mol of molecules contains NA of molecules

NA = 6.02×10²³

Now, we make rules of three:

1 mol has 6.02×10²³ molecules, therefore:

8.55 moles of SO₂ must have (8.55 . NA) / 1 = 5.15×10²⁴ molecules of dioxide

0.603 moles of CO must have (0.603 . NA) / 1 = 3.63×10²³ molecules of monoxide

Avogadro's Number of molecules of NH₃ are 6.02×10²³ molecules of ammonia

Chemical reaction to form products this chemical equation represents one such reaction the coefficient for one of the reactants
Dmitriy789 [7]

Answer:

In a chemical equation, chemicals that react are the reactants, while chemicals that are produced are the products/by products. Both sides of the equation must be balanced.

\

Explanation

When writing a chemical equation, reactants reacts to produce products. For example in the equation for formation of water, hydrogen combines with oxygen as 2H₂ +O₂→2H₂O where the first part before the arrow represent the reactants and the next part after the arrow are the products. Reactants are on the left where as products are on the right.Coefficient 2, in this cases is used for balancing the equation

The radioactivity due to carbon-14 measured in a piece of a wooden casket from an ancient burial site was found to produce 20 co
bekas [8.4K]

Answer:

17202.6 years

Explanation:

Activity of the living sample (Ao) = 160 counts per minute

Activity of the wood sample (A) = 20 counts per minute

Half life of carbon-14 = 5730 years

t= age of the artifact

From;

0.693/t1/2= 2.303/t log Ao/A

Then;

0.693/ 5730= 2.303/t log Ao/A

Substituting values;

0.693/5730= 2.303/t log (160/20)

Then we obtain;

1.209×10^-4 = 2.0798/t

t= 2.0798/1.209×10^-4

Thus;

t= 17202.6 years

Therefore the artifact is 17202.6 years old.
