I'm a pharmacy dispenser which is the same thing. what's your question?
Answer:
First check to make sure you have a balanced equation
Second use mole ratios to set up what you need to know
Finally convert the moles to grams using the correct molecular weight
I will get you started
According to the reaction above, one mole of Magnesium Nitrate is produced from 2 moles of Nitric Acid
1 mole of Mg(NO3)2/2 moles of HNO3
5 grams of Nitric acid contains
5 g * 1 mole/63 g of Nitric Acid = 0.079365079 moles
Explanation:
It is directly proportional
Answer:
Boiling water breaks intermolecular attractions and electrolysis breaks covalent bonds.
Explanation:
When water boils, hydrogen bonds are broken between adjacent water molecules. The hydrogen bond is an intermolecular bond between adjacent oxygen and hydrogen atoms of water molecules.
During electrolysis, water dissociates in the presence of electric current. Here, ions are formed in the process. Therefore, covalent bonds are broken here.
Answer:
Density is the total number of particles in a given volume
Explanation:
As per the particle theory, density is defined as total space occupied by certain number of particles of any given element with in a defined volume is termed as density.
Density is not the denseness of a single unit but the space occupied by many single units with in a given volume V
Hence, density is the total number of particles in a given volume.
