Answer:
0.0634 M HCl
Explanation:
Since HCl and NaOH react in a one-to-one mole ratio, we can just use M1V1 = M2V2 to solve for M1 (the concentration of HCl)
M1 = ? M HCl
V1 = 24.30 mL HCl
M2 = 0.120 M NaOH
V2 = 12.84 mL NaOH
M1(24.30 mL HCl) = (0.120 M NaOH)(12.84 mL NaOH)
M1 = 0.0634 M HCl
Answer:
Option 4) equal to
Explanation
When having a reversible reaction, this reaction (or system) reaches the balnace, it is observed that relative quantitives for all compounds (this is, reactives and products), remain constant
The species concentration does not change over time, and; in the same way; there are no physical changes as time goes by
For example, for the following reaction :
aA + bB ⇔ cC + dD
Compounds A and B react to give products C and D. The two way arrows means that this systme has reached the balance (is in equilibrium)
Answer:
2k+2hcl---2kcl+h2
Explanation:
because we have to balance it and in order to balance it we have to make it in equal form
