For all question, all you need to use is the mole-mole ratio.
a) 25 moles C2H6O (3 moles O2/ 1 mol C2H6O)= 75 moles O2
b) 30 moles O2 (1 moles C2H6O/ 3 moles O2)= 10 moles C2H6O
c) 23 moles CO2 (3 moles O2/ 2 moles CO2) = 34.5 moles O2
d) 41 moles H2O ( 1 moles C2H6O/ 3 moles H2O= 13.7 moles C2H6O
Answer:
Most similar - Lithium
Least similar - Phosphorus
Explanation:
Rubidium is an element in group 1A of the periodic table. It is a metal and forms an ionic compound with chlorine. The formula of the compound is RbCl.
If we look at the options, Lithium is also a group 1A element and forms an ionic compound with chlorine having the formula LiCl which is very much similar to RbCl chemically.
Phosphorus is a nonmetal. Its compounds with chlorine, PCl3 and PCl5 are covalent and does not resemble RbCl in any way.
Yes , I agree with the statement water contains minerals
<u>Explanation:</u>
- When LaShawna saw the steam, she said that the water must contain a lot of minerals and the statement is true.
- Most of the water comes from the underground supply and they undergo some cleaning process and stuff.
- Usually, mineral water comes from natural underground water supply and the springs.
- Chemical compounds like Calcium, potassium, sodium, iron are present in water.
- Magnesium plays an essential function in maintaining blood supply and high mineral content water helps us to prevent or lower the heart-related disease.
- Calcium is the building block for maintaining the bone's health.
