<u>Answer: </u>54 molecules of water will be formed in the reaction.
<u>Explanation:</u>
A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.
For the given unbalanced chemical equation, the balanced equation follows:
We are given:
Molecules of = 6
Molecules of = 75
By the stoichiometry of the reaction:
If 2 molecules of produces 18 molecules of water
So, 6 molecules of will produce = molecules of water
Hence, 54 molecules of water will be formed in the reaction.
<span>Let's </span>assume that the gas is an ideal gas. Then we can use ideal gas equation,<span>
PV = nRT<span>
</span>Where,
P = Pressure of the gas (Pa)
V = volume of the gas (m³)
n = number of moles (mol)
R = Universal gas constant (8.314 J mol</span>⁻¹ K⁻¹)<span>
T = temperature in Kelvin (K)
<span>
The given data for the </span></span>gas is,<span>
P = ?
V = 9.5 L = 9.5 x 10</span>⁻³ m³<span>
T = (273 + 20) K = 293 K
R = 8.314 J mol</span>⁻¹ K⁻¹<span>
n = 1.2 mol
by applying the formula,
P x </span>9.5 x 10⁻³ m³ = 1.2 mol x 8.314 J mol⁻¹ K⁻¹ x 293 K
<span> P = 307705.5 Pa
P =3.08 x 10</span>⁵ Pa
<span>
Hence, the pressure of the gas is </span>3.08 x 10⁵ Pa.<span>
</span>
It determines the genetic and inherited factors.
Answer:
each of more than one hundred substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter. Each element is distinguished by its atomic number, i.e. the number of protons in the nuclei of its atoms.
