Covalent bonds hold hydrogen and oxygen together.
Answer: Pumping can affect the level of the water table. In an aquifer, the soil and rock is saturated with water.
Explanation:
The mass of water that will be needed to make the solution is calculated as below
% solution = mass of the solute/mass of the solvent(water) x100
% solution = 5% = 5/100
mass of the solute =0.377 g
mass of the solvent = ?
let the mass of the solvent be represented by Y
= 5/100 =0.377/y
by cross multiplication
5y= 37.7
divide both side by 5
y =7.54 grams
2Zn(g)+2Hcl(aq)---->2ZnCl(s) +H2(g)
