Answer:
volume of carbon dioxide gas would be collected during a one-year period.
Explanation:
Mass of carbon dioxide gas collected in a day = 31,000 Tonn
1 Tonn = 1000 kilogram
31,000 Tonn = 
Specific volume of the carbon dioxide gas = 
Volume of carbon dioxide gas collected in a day = V
1 year = 365 days
Volume of carbon dioxide gas collected in a year = V'
volume of carbon dioxide gas would be collected during a one-year period.
Answer: B) 46.7% Si and 53.3% O
Explanation:
To calculate the mass percent of element in a given compound, we use the formula:
Mass of quartz 
= 5.05 g
Mass of silicon = 2.36 g
Mass of oxygen = Mass of quartz - mass of silicon = 5.05g - 2.36 g = 2.69 g
Thus the percentages of silicon and oxygen in quartz are B) 46.7% Si and 53.3% O
Answer:
neon is the Noble gas but I have not studied this much
Answer:
<em>The ionic radius is the the distance from the nucleus to the outermost electrons in a ion. While the atomic radius is the distance from the nucleus to the normal valence electrons.The ionic radius is half the distance between two gas atoms that are just touching each other. If the atom loses its outermost electron (positively charged or cation), the ionic radius is smaller than the atomic radius because the atom loses an electron energy shell.</em>
