Answer:
Protons
Explanation:
Electrons have a negative charge which are found in shells around the nucleus. The nucleus consists of protons and neutron and the neutron has a neutral charge.
<span>You are trying to find V2, the formula is V2</span>= <span><span>P1 / </span><span>P2 </span></span>⋅ V<span>1
</span><span>input your numbers, V2</span>= <span><span>90.0kPa / </span><span>20.0kPa </span></span>⋅ 4.0 L to get 18 L
It has a negative charge emits energy when it moves to a lower energy orbit from an excited state and it has the same mass as a proton
Answer:
Distillation.
Explanation:
If we are heating a mixture of two miscible liquids and collecting the vapors it means we are separating the two mixtures from each other based on their boiling point differences.
This technique of separation of two liquids based on the difference in boiling point is known as Distillation.
Alcohol will evaporate easily as compared to water as water has stronger influence of hydrogen bond making the inter-molecular forces stronger.
Answer:
Different substances have different molecular masses. Thus, equal masses have different numbers of atoms, molecules, or moles. On the other hand, equal numbers of moles of different substances have different masses.
