Answer:
c. a proton
Explanation:
A neutron is most equal in mass to a proton.
A neutron is a subatomic particle without any charges on them.
A proton is a subatomic particle with a positive charge.
- the mass of a proton and neutron are the most similar in an atom.
- the mass of a proton is 1.67 x 10⁻²⁷kg
- So also is the mass of a neutron
- the mass of an electron is 9.11 x 10⁻³¹kg

<span>20%. By forming an iceglaze over the surfaces, freezing precipitation accounts for 20% of all winter weather related injuries in the United States. When the freezing precipitation leads to accumulation of 0.25 inch ice, it is known as Ice storm.</span>
Answer:
44.8 dm3
Explanation:
mole=volume÷molar volume
Transpose the formula because you want to find the volume.
<em>volume=mole×molar volume</em>
NB STP IS 22.4 mol/dm3
2mol×22.4mol/dm3
=44.8dm3
Answer:
due to half filled and full filled effects
Explanation:
Cr shows half filled stability,when filling electrons in its orbitals while Cu shows full filled stability when filling electrons in its orbitals
