Second imagine is correct
Answer: 3 moles of HCl
Explanation: let’s do a balanced chemical equation
Al(OH)3 + 3HCl —> AlCl3 + 3H2O
We see that for every 1 mole of Al(OH)3 we need 3 moles of HCl
In picture one and picture three there is an even amount of both X and Y. But in picture two there is double the amount of X than there is Y which also would change the rate from being .10 to .20
Answer:
320 mmol
Explanation:
405.0 mL * 1L/1000 mL = 0.4050 L
0.79 M = 0.79 mol/L
0.79 mol/L * 0.4050 L=0.32 mol
0.32 mol * 10^3 mmol/1 mol = 320 mmol
