K2O + CaBr2 ---> CaO + 2 KBr
Unable to read second question properly sorry
Answer:
82.04g
Explanation:
To solve this problem, you need to find the molar mass of HCl, which is the sum of the molar mass of H plus the molar mass of Cl. The molar mass of H is 1.008g/mol while the molar mass of Cl is 35.45g/mol. Thusly the molar mass of HCl is 36.458g/mol. You have 2.25 moles of HCl, so multiply the number of moles by the molar mass to get the mass in g. In this case it is 2.25mol * 36.458g/mol = 82.04g.
If I helped, a brainliest would be greatly appreciated!
He concluded that all tissues are made up of cells.
I think the answer is covalent bonds.
Because each carbon atom can form for chemical bonds to another’s atoms and because the carbon atom is just the right small size to fit in comfortably as parts of very large molecules
