The nucleus is the centre of an atom, and it's assumed that is where the proton and neutron are located. Electrons are though to orbit around the nucleus, so the answer is (1) an electron
There is 0.02538502095915 Moles in 5 grams of gold.
Answer:
I believe the answer is A.
Explanation:
This section states that protozoa live in all bodies of water therefore B can not be an answer because it says protozoa dose not live in any body of water.
I hope this answers your question.
The pH of the weak acid is 6.93.
Given,
K= 1.15 *
c=0.102
[H]= K*c= 1.15 *
* 0.102= 0.1173 *
p[H]= -log[H]= 6.93
<h3>Weak acid</h3>
A weak acid is one that partially separates into its ions in water or an aqueous solution. A strong acid, on the other hand, completely splits into its ions in water. The conjugate base of a weak acid is also a weak base, and vice versa for the conjugate acid of a weak base. Weak acids have a higher pH than strong acids at the same concentration. Simple arrows pointing left to right are used to represent the reaction of a strong acid ionising in water. On the other hand, a weak acid ionising in water has a double arrow reaction arrow, indicating that both the forward and reverse reactions take place at equilibrium.
