Answer:
A
D
E
and maybe C I'm not sure on that one.
Explanation:
Answer:
pOH = 4.63
pH = 9.37
Explanation:
Because NaOH is a strong base, it will completely dissociate, which means you can find pOH by taking the negative log of the concentration of hydroxide ions: pOH = -log(OH) = -log(2.34 x 10⁻⁵) = 4.630784143
To find pH use 14.00 = pH + pOH
pH = 14.00 - 4.630784143 = 9.369215857
Answer:
The rate of the catalyzed reaction will increase by a 1.8 × 10⁵ factor.
Explanation:
The rate of a reaction (r) is proportional to the rate constant (k). We can find the rate constant using the Arrhenius equation.
where,
A: collision factor
Ea: activation energy
R: ideal gas constant
T: absolute temperature (125°C + 273 = 398 K)
For the uncatalized reaction,
For the catalized reaction,
The ratio kC to kU is 6.0 × 10⁻⁸A/3.4 × 10⁻¹³A = 1.8 × 10⁵
Answer:
<h3>The answer is 19230.8 kg/m³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 500 kg
volume = 0.026 m³
We have
We have the final answer as
<h3>19230.8 kg/m³</h3>
Hope this helps you
Neutral atoms have the same number of electrons and protons giving them a neutral charge. A ion is an atom with a net electric charge due to the losing or gaining electrons.
