They are directly proportional to each other, in other words, when temperature of an object increases, the motion of it's particles also increases
Hope this helps!
Answer:
Opion 4. The hydrogen in HCl reduce from proton to hydrogen gas (H at ground state)
Explanation:
The reaction is: Mn + HCl → MnCl₂ + H₂
Magnessium changed the oxidation state from 0 to +2
It has increased, so it was oxidized
H changed the oxidation state from +1 to 0
It has decreased, so it was reducted.
The density of this gas is 0.20 g/L.
<h3>What is density?</h3>
The density of a substance is the measure of how densely it is packed together. The mass per unit volume is how it is formally defined. The symbol for density: d
The density formula is given by d = m/v, where m is the object's mass and v is its volume.
Given that,
Molar volume of non ideal He gas (v) = 20 L/mol
Molar mass of He gas (m) = 4.0 g/mol
As we know, density of this gas (d) = mass (m) / volume (v)
= 4.0g /20L
= 0.20 g/L
Thus, density of this gas is 0.20 g/L
