Water-rich solutions carrying metallic salts fill cracks and form <u>veins</u>.
Answer:
100 mL is the volume of HCl needed to neutralize the 44.3 of Ba(OH)₂
Explanation:
This is the chemical equation:
2HCl + Ba(OH)₂ → BaCl₂ + 2H₂O
Formula for neutralization is:
Molarity of acid . Volume of acid = Molarity of base . Volume of base
0.121 . Volume of acid = 0.274 . 44.3
Volume of acid = (0.274 . 44.3) / 0.121 → 100
Rocks are part of our planet. They tell stories like how they were formed and which environment they belong in. And it also tells us things about the past, because rocks came long before humans did.
Answer:
E. Cl2 + 2NaBr ----> Br2 + 2NaCl
Explanation:
Number of Cl molecules is 2 on the reactant and product side of the equation.
Number of Na molecules is 2 on the reactant and product side of the equation.
Number of Br molecules is 2 on the reactant and the product side of the equation.
As the reactant side is equal to the product side, the equation is balanced.
