Answer:

445K

Explanation:

according to universal gas theoreme, p1v1/T1=p2v2/T2

therefore, T2=(56.7×8×298)/(3.5×86.7)

≈445K

Vedmedyk [2.9K]

Answer:

72.6% Error

Explanation:

% error = $\frac{Real-Measured}{Real} * 100$

$\frac{58.44-16}{58.44} *100= 72.6$

58.44 is the weight of NaCl

A solution has a<br> pH of 2.5.<br> Answer the following questions.<br> pOH =<br> [H]=<br> [OH]=

Sloan [31]

Answer:

pOH = 11.5

[H⁺] = 0.003 M

[OH⁻] = 3 × 10⁻¹² M

Explanation:

The computation is shown below:

Given that

pH = 2.5

Based on the above information

We know that

pH + pOH = 14 ⇒ pOH = 14 - pH

pOH = 14 - 2.5

pOH = 11.5

[H⁺] = 10^(-pH) = 10^(-2.5)

[H⁺] = 0.003 M

[OH⁻] = 10^(-pOH)

= 10^(-11.5)

= 3 × 10⁻¹² M

[OH⁻] = 3 × 10⁻¹² M

Hence, the above represents the answer
