Answer:
pH = 5.00
Explanation:
The pH is an unit of concentration widely used in chemistry and quality control of aqueous solutions. It serves to find the security of a product to human or pet consumption. Is defined as:
pH = -log [H+]
That means, the pH of a solution that is [H+] = 1.00x10⁻⁵M:
<h3>pH = 5.00</h3>
Answer:
b
Explanation:
the fungi Greenwich the methicillin. to take it away is taking water away from human
Balanced equation: Mg+2HCl=MgCl2 + H2
Showing that if Mg is not a limiting factor then 2 moles of HCl on complete reaction liberate 1 mole of Hydrogen
therefore:
1 mole of HCl=35.5g, 40g=x
X= 40/35.5= 1.127mole
2 moles of HCl = 1 moles of Hydrogen
1.127=X
X=1.127/2 = 0.56
the theoretical yield of hydrogen
The meaning of observations to see small touch
Explanation:
nuclear fusion yields more energy than nuclear fission and the products of the reaction are not radioactive
