Answer:
Nonmetals are elements that generally cannot conduct electricity. They are the second largest class of elements after metals. Examples of nonmetals include hydrogen, carbon, chlorine, and helium. Properties of nonmetals include a relatively low boiling point, so many nonmetals are gases.
It would be considered a Nonmetal

Complete Question
The complete question is shown on the first uploaded image
Answer:
The pressure is
Explanation:
From the question we are told that
The mass of the carbon monoxide is
The temperature at which takes place
The volume of the sealed vessel is
Generally the ideal gas law is mathematically represented as
Where R is the gas constant with value
n is the number of moles of carbon monoxide which is mathematically evaluated as
where is the molar mass of carbon monoxide which is a constant with value
So
Now Making P the subject we have
Answer:
The solubility of the salt is
46.75g salt/100g of H2O
Explanation:
If 7.70g of water can dissolve 3.60g at 21°C
That is 1.0g of water can dissolve (3.6÷7.7) grams of salt, that is 0.4675_g of salt at 21°C or 100 grams of water can dissolve 100×0.4675 = 46.75g
The solubility of the salt is
46.75g salt/100g of H2O
25:18 meaning for every 25 moles of oxygen there's 18 moles of water
