I don't see any options to choose from, but, I have seen this question.
When comparing the masses of two subatomic particles, the mass of a proton is greater than the mass of an electron.
Brainlest answer is always appreciated ( ͡ ͜ʖ ͡ )
A wave.
Scientists now recognize that light can behave as both a particle and a wave.
The kind of reaction involving the transfer of electrons or hydrogen away from a molecule is called oxidation.
In the same vein, the molecule that receives the electron or the hydrogen atom is said to be reduced. This means that oxidation cannot exist in isolation without reduction.
In other words, oxidation is defined as:
- Loss of electrons
- Loss of hydrogen atoms
- Gain of oxygen atoms
- Gain in oxidation number
While reduction is defined as:
- Gain of electrons
- Gain of hydrogen atom
- Loss of oxygen atom
- Reduction in oxidation number

Answer:
0.01504 mol/dm3
Explanation:
Calcium Hydroxide - Ca(OH)2
Hydrochloric acid - HCl
The reaction between both is given as;
2HCl + Ca(OH)2 --> CaCl2 + 2H2O
2 : 1
The relationship between the concentration and volume is given as;
CaVa / CbVb = na / nb
where a = acid (HCl) and b = base Ca(OH)2
Inserting the values;
0.04 * 18.8 / (Cb * 25) = 2 / 1
0.752 / 25Cb = 2
Cb = 0.752 / 50 = 0.01504
