Answer:
Protons, neutrons, and electrons
Explanation:
Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.
Answer:
Explanation:
We will need a balanced chemical equation with masses, moles, and molar masses.
1. Gather all the information in one place:
Mᵣ: 18.02
2Na + H₂O ⟶ 2NaOH + H₂
m/g: 72.0
2. Moles of H₂O
3. Moles of Na
The molar ratio is 2 mol Na/1 mol H₂O.
Answer: exothermic
Explanation: chemical reactions that release energy is called exothermic, and in this case, more energy is being released. (I THINK)
Venus is the hottest planet because of the dense atmosphere but also because it has acidic clouds and it is the second closest planet to the sun.
For Gabriel synthesis halides should be primary.
<span>a.1-bromopentane -primary
b.1-bromo-3-methylbutane -pimary
c.2-bromo-3-methylpentane -secondary - cannot be used
d.1-bromo-2,3-dimethylbutane -primary
e.2-bromo-2,3-dimethylbutane- tertiary -cannot be used
I think it should be like this</span>
