Answer:

Explanation:
Glucose reacts with oxygen do produce carbon dioxide and water:

Given a daily mass of glucose:

Find moles of glucose:

From stoichiometry of this equation, moles of carbon dioxide can be found by multiplying this amount by 6:

Convert this into mass using the molar mass of carbon dioxide:

This is the mass of carbon dioxide per person per day. Multiply by the population and by the number of days to get the total mass:

As you move around there is a change in: electronegativies, ionisation energies, atomic radius etc. different amounts of these properties are going to effect how the element acts
Answer:
<h2>Volume = 9.29 mL</h2>
Explanation:
Density of a substance can be found by using the formula

From the question
Density = 11.3 g/mL
mass = 105 g
Substitute the values into the above formula and solve for the volume
That's

Cross multiply
11.3v = 105
Divide both sides by 11.3

v = 9.29203
We have the final answer as
<h3>Volume = 9.29 mL</h3>
