Point f because that is when it starts going down
Answer: to calculate pH use -log[H+] or - log[OH-]..the solution is basic as the “NaOH” is attached to a hydroxide.Since we need to find the pH (per hydrogen) and not the pOH( per hydroxide) we need to find the pOH of the substance first then we subtract that by 14 so we can arrive at the pH of the substance.
Explanation: So -log( 1 x 10^(-5)) = 5 which is the pOH.Now we subtract that by 14 which gives us -9 and now you’d multiply that by -1 bcuz we can’t have a negative so the pH of the substance is 9
Answer:
The third one
Explanation:
Nickel-62 has the highest binding energy per nucleon of any isotope for any element. Isotopes heavier than 62Ni cannot be formed by nuclear fusion without losing energy.
Viruses always have a host to latch on. When latched on, viruses will inject its protein or RNA into the host.
Viruses aren’t considered organic.
Bacteria has a nucleus and cell membranes while viruses don’t
Viruses are not considered organic while bacteria are.
Answer:
We have the final answer as

Explanation:
To find the energy of a photon of this light we use the formula
<h3>E = hf</h3>
where
E is the energy
f is the frequency
h is the Planck's constant which is
6.626 × 10-³⁴ Js
From the question
f = 7.08×10¹⁴ Hz
We have
E = 7.08×10¹⁴ × 6.626 × 10-³⁴
We have the final answer as

Hope this helps you
