If the hydroxide ion concentration of a solution is 3.26 x 10-6 M, is it an acidic or a basic solution?

sladkih [1.3K]

Answer: It is a basic solution with pH =8.51

Explanation:

We were given that hydroxide ion concentration [OH-] as 3.26 x 10-6 M

But We know thar

[OH-] [H+] = 1 × 10^-14

To get the Hydrogen ion [H+] concentration, we have that

[H+] = 1 × 10^-14 M/[OH-]

= 1 × 10^-14 M/3.26 x 10-6 M

= 3.067 x 10^-9 M

But, pH = - log [H+]

Therefore,

pH = - log (3.067 x 10^-9)

pH=8.51

when pH > 7, The solution is basic, therefore a solution with pH =8.51 is basic.

2C4H10 + 13O2 Right arrow. 8CO2 + 10H2O

What is the mole ratio of butane to carbon dioxide?

ANSWER:

Butane is an organic compound with the formula C4H10 and carbon dioxide is compound (gas) with the formula CO2. So, the balanced coefficient of butane is 2, and that of carbon dioxide is 8. According to thid, the mole ratio of butane to carbon dioxide is 2:8 or 1:4.

When a 10 mL graduated cylinder is filled to the 10 mL mark, the mass of the water was measured to be 9.925 g. If the density of

Vlada [557]

Measured volume = 10 ml
mass = 9.925 g
density = 0.9975 g/ml
density = $\frac{mass}{volume}$
so actual volume = $\frac{mass}{density}$ = $\frac{9.925}{0.9975}$ = 9.95 mL
Percentage Error = $\frac{measured volume - Actual volume}{actual volume}$ x 100
= $\frac{10 - 9.95}{9.95}$ x 100 = 0.5 % error
