To determine the pH of the solution. All you would have to do is use the equation:
pH = -log(H3O^+)
pH = - log(0.0007)
pH = 3.15.
Note that H+ and H3O+ are the same, it is more accurate to say H3O+ because of how the H2O molecules become after receiving the additional proton.

Answer:
1970
Explanation:
1970, Canada gradually began to convert from an imperial to a metric system of measurement
The oxidation number<span> of a Group 2 element in a </span>compound<span> is +2. The </span>oxidation number<span> of a Group 17 element in a binary </span>compound<span> is -1. The sum of the </span>oxidation numbers<span> of all of the atoms in a neutral </span>compound<span> is 0. The sum of the </span>oxidation numbers<span> in a polyatomic ion is equal to the charge of the ion.</span>
Answer:
45K
Explanation:
Rise in temperature = Final - initial temperature.
temperature in K = Temperature in Celsius + 273
for Celsius; T2 -T1 =45°C
for kelvin; T2+273 -(T1+273) = ?
T2+273 -T1-273 =?
T2-T1 = ?
T2-T1 =45k
hence ΔT(K) = ΔT(°C) (temperature difference in Celsius is equal to temperature difference in kelvin)
