Answer: What is the mass of disulfur pentoxide (S2O5)?
Explanation:144.14g/mol
Answer:
1)KNO3 ( pottasium trioxonitrate (V)
2)Ca(NO3)2 (calcium trioxonitrate (V
Explanation:
1)KNO3 ( pottasium trioxonitrate (V)
2)Ca(NO3)2 (calcium trioxonitrate (V)
Thses two compounds are metallic compounds and does not react with either the acid or the base.
Write the type of metal, based on your examination of the periodic table?
1)KNO3 ( pottasium trioxonitrate (V) have a potassium element which belongs to group 2 of the Periodic table which is an alkaline metal and can react with water or steàm
2)Ca(NO3)2 (calcium trioxonitrate (V) has calcium metal element which is an alkaline earth metal in the Periodic table and they react with Hallogens
Hydrogen is usually –1. This is INCORRECT. The oxidation number for H is +1.
Oxygen is usually –2. This is CORRECT.
A pure group 1 element is +1. This is INCORRECT. It does not follow. This will depend on the other elements and the overall charge.
A monatomic ion is 0. This is INCORRECT. Diatomic ion is 0.
I think It’s 55 but that’s just me
Answer:
Amount of gas
Explanation:
The combined gas law has to do with pressure, volume, and temperature. All of them can be a variable that you have to solve for. However, amount of gas is not a variable you can solve for, which means it must remain constant.
