Answer:
C- A proton has about the same mass as a neutron .
Explanation:
In an atom such as a carbon atom, the masses of the proton and neutrons are the same.
The mass of the electrons is very negligible.
- Protons are the positively charged particles in an atom
- Neutrons do not carry any charges
- Both protons and neutrons have similar masses.
- They contribute the bulk of the mass of the atom.
- The electrons carry negative charges and they have negligible masses.
The mass of protons and neutrons are similar.
<span>4.5x10^22
Because there are 6.022x10^23 atoms per mole; therefore,
(6.022x10^23*(0.075)=04.5x10^22 atoms of titanium.</span>

Explanation:
Answer:
b.) 25 ml of aluminum hydroxide
Explanation:
For this question, we have to assume that we have the <u>same concentration</u> for all the solutions, for example, <u>1 M</u>. Additionally, we have to take into account the <u>ionization reaction</u> for each species:
a) <u>we have to ions</u>
b) <u>we have fourth ions</u>
c) <u>we have two ions</u>
d) <u>we have one ion</u>
If we have the same volume and the same concentration the variables that will help us to answer the question would be the n<u>umber of ions.</u> If we have <u>more ions we will have more particles dissolved</u>. Therefore the answer would be b) (<u>due to the fourth ions</u>).
I hope it helps
