Charle's law states that at constant pressure, absolute temperature and volume are proportional. Mathematically,
V ∝ T. T, the temperature, is quoted in Kelvins.
Explanation:
Given the proportionality, <span><span>V1</span><span>T1</span></span> = <span><span>V2</span><span>T2</span></span>. <span>V2</span> is unknown but <span>V2</span> = <span><span><span>T2</span>×<span>V1</span></span><span>T1</span></span>
Remember, that this assumes a constant pressure. Charles' law is also the reason that we can fly hot air balloons. The experiment has doubled the temperature, so how will volume evolve? Will it get bigger, smaller, remain the same?

Answer:
The number of carbon atoms in the container is 1.806 × 10²⁴ or the container contains 1.806 × 10²⁴ atoms of carbon
Explanation:
By Avogadro's number, 1 mole of a substance contains 6.02 × 10²³ particles of the substance
Here we have 0.45 mole of CO₂ contains
0.45 × 6.02 × 10²³ particles of CO₂ that is 2.709 × 10²³ particles of CO₂ or equivalent to 2.709 × 10²³ atoms of Carbon
Similarly, 2.55 moles of CaC₂ contains 2.55 × 6.02 × 10²³ particles of CaC₂ or 1.5351 × 10²⁴ atoms of Carbon
The total number of carbon atoms is therefore;
2.709 × 10²³ + 1.5351 × 10²⁴ = 1.806 × 10²⁴ atoms of carbon.
Answer:
B. The atom has two more electrons than an atom of oxygen.
Explanation:
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.
Oxygen has a total number of eight (8) electrons while neon has total number of ten (10) electrons. Therefore, an atom of oxygen is able to gain (receive) two (2) more electrons in order to have the same electron arrangements as the noble gas i.e an atom of neon with an atomic number of 10.
This ultimately implies that, an
atom contains the same number of electrons as an atom of neon.
Hence, a neon atom has two more electrons than an atom of oxygen.
Additionally, Neon is used in lighting advertising displays.
