Answer:
B. electrons possess the largest charge-to-mass ratio among the subatomic particles listed in the four choices.
Explanation:
Consider the mass of each particle. Express the masses in atomic mass units:
- Protons: approximately 1.007 amu each;
- Neutrons: approximately 1.009 amu each;
- Electrons: approximately 0.0005 amu each.
Similarly, consider the charge on each particle. Express the charges in multiples of the fundamental charge:
- Protons: +1 e;
- Neutrons: 0;
- Electrons: -1 e.
Calculate the charge-to-mass ratio for the three species:
- Protons: approximately
; - Neutrons: 0;
- Electrons: approximately
.
Almost all nuclei contain protons and neutrons. The only exception is the hydrogen-1 nucleus, which contains only one proton and no neutron. The mass of the nucleus is approximately the same as the sum of its components' masses. The extra neutron will only add to the mass of the nucleus (the denominator) without contributing to the charge (the numerator.) As a result, the charge-to-mass ratio of nuclei will be positive but no greater than the charge-to-mass ratio of protons.
Among the particles in the four choices, the charge-to-mass ratio is the greatest for electrons.
I'm not sure what type of fuel you're talking about. If you mean fossil fuel then kerosene has the highest density of all of the things you listed.
Answer:
sun rises in the east so to the right of the front of your house and sets to the left which is south.
Explanation: what i just said
Answer:
Explanation:
Similarities.
Both Ionic and covalents bond produce exothermic reactions.
They are both neutral.in Ionic bonds, the two opposite charge will terminate each other and in covalent, the neutral molecules tend to share electrons.
Difference
Ionic bonds have high polarity while covalent have low.
Ionic bonds have no definite shape, covalent have.
Ionic have high melting points, covalent have low.
Io ic have high boiling point, covalents have low.
All solutions are mixtures of two or more substances, but unless the mixture has a homogeneous distribution of solutes in the solvent, then the mixture is not a solution. Therefore, all mixtures are not solutions.
