Since the mole ratio is 1 to 1 for this reaction, you can just use M1V1 = M2V2 to solve, given that 1 refers to HBr and 2 refers to LiOH.
M1 = ?
V1 = 0.40 L
M2 = 0.50 M
V2 = 0.20 L
M1(0.40) = (0.50)(0.20)
Solve for M1 —> M1 = (0.50)(0.20)/0.40 = 0.25 M HBr
Answer:
Garnet is a hard transparent mineral that is often used as gemstones and abrasives and quartz is the most abundant mineral on the earth's surface. They are both minerals that come out of the earth and that's about the most they have in common.
Explanation:
I got this answer correct.
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.
