According to my calculations the correct Answer is C. +694. The answers A B and D Are incorrect. It cannot be A because I said it also cannot be B because C=H. The answer would not be D because balls in your jaws = +1192 And the answer will be CORRECT ANSWER C=+694
Answer:
The range of variation under which a species can function and reproduce is called its tolerance range.
Explanation:
PLZZZ MARK ME BRAINLIESTTTTT
We first calculate the number of moles of K2CrO4 by multiplying the volume with the molarity.
n = (25/1000) x (3 M) = 0.075 mol K2CrO4
Then, from the balanced chemical equation, each mole of K2CrO4 will produce 1 mole PbCrO4 with molar mass of 323.2 g/mol.
(0.075 mol K2CrO4)(1 mol PbCrO4/1 mol K2CrO4) x (323.2 g/mol)
= 24.24 grams PbCrO4
The molarity of the HBr solution is 0,172 M.
The neutralization reaction between LiOH and HBr is the following:
HBr(aq) + LiOH(aq) → LiBr(aq) + H₂O(l)
