From the family pictures, people looked alike because they share similar genes.
<h3>What are genes?</h3>
Genes are units of inheritance located on the chromosomes which are passed on from parents to offspring. Members of a family look alike because of the genes that are passed on from parents to offspring.
Hence, from the family pictures, people looked alike because they share similar genes.

V1 = 30 mL
P1 = 760 torr
P2 = 1520 torr
V2 = ?
applying Boyle's Law
P1*V1 = P2*V2
760 torr * 30 mL = 1520 torr * V2
V2 = 760 torr * 30 mL / 1520 torr
( C ) is correct
I got 0.001912 using dimensional analysis. See the picture for work.
Answer:
The positive charge in carbon is C
Explanation:
Atomic weight: An atom consists of protons, neutrons and electrons. Atomic mass is the sum of the number of protons and neutrons. The average weight of mass is called atomic mass of that atom.
The positive charge of an atom is proton.
The atomic weight of carbon = 12.0107 g/mol
Avogadro's number = 6.023×10⁻²³ atom/ mol
Charge = 1.602×10⁻¹⁹ C
The weight of carbon = 0.9 kg = 900 gram
Number of protons in carbon = 6
The positive charge in carbon is
=No. mole× Avogadro's Number× No. proton × charge per proton
C
Answer:
When a substance gains or loses energy, its <u>temperature</u> or <u>state</u> changes. These two changes do <u>not</u> happen with respect to time; the temperature remains <u>the same</u> until the change of <u>state</u> is complete.
Explanation:
This statement is about energy and change of the state of the matter. By gaining or losing energy, the physical state of the matter can change into one another. Melting, freezing, condensation, evaporation, sublimation, and deposition are the processes that support to change the physical state of the matter. Change in state and change in the matter do not happen at the same time. A substance gains or loses energy to reach a specific temperature and remains constant until the physical change of matter is completed.
