The equation for calculating a mass is as follows:

m=n×M

Molar mass (M) we can determine from Ar that can read in a periodical table, and a number of moles we can calculate from the available date for N:

n(H2SO4)=N/NA

n(H2SO4)= 1.7×10²³ / 6 × 10²³

n(H2SO4)= 0.3 mole

Now we can calculate a mass of H2SO4:

m(H2SO4) = n×M = 0.3 × 98 = 27.8 g

A bicycle rusting after it is left in the rain is an example of a chemical reaction because it involves oxidation (Option d).  

<h3>What is a chemical reaction?</h3>

A chemical reaction can be defined as a phenomenon in which one or more substances called reactants react to form one or more different compounds, which are known as products.

A chemical reaction may include an enzyme that works to increase the seed of the reaction in normal conditions by lowering the activation energy of the reaction.

Therefore, we can conclude that a chemical reaction such as oxidation in a bicycle is a process where reactants combine or break down to form the products of such reaction.

Answer:

"Thermometer C, because it measures accurately in the ones place."

Explanation:

Thermometer D measures using tens place. Since we are measuring the liquid's temperature at 47 degrees Celsius, the most appropriate thermometer would measure in ones place, not tens place.

Hope this helps! :)
