Answer:
Explanation:
Thomas is incorrect because acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
N₂ : limiting reactant
H₂ : excess reactant

Given
mass of N₂ = 100 g
mass of H₂ = 100 g
Required
Limiting reactant
Excess reactant
Solution
Reaction
<em>N₂+3H₂⇒2NH₃</em>
mol N₂(MW=28 g/mol) :
mol H₂(MW= 2 g/mol) :
A method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients, and small or exhausted reactans become a limiting reactants
From the equation, mol ratio N₂ : H₂ = 1 : 3, so :
N₂ becomes a limiting reactant (smaller ratio) and H₂ is the excess reactant
Lines in one spectral series can overlap lines in another is rydberg
In several chemical elements, the Rydberg formula is used to compute the wavelengths of spectral lines.
<h3>
What causes lines in a line spectrum?</h3>
A spectral line is similar to a fingerprint in that it can be used to identify the atoms, elements, or molecules in a star, galaxy, or cloud of interstellar gas. When we use a prism to split incoming light from a heavenly source, we often observe a rainbow of colours crossed by definite lines. It's worth noting that spectral lines can appear in other parts of the electromagnetic spectrum, however we can't use a prism to assist us identify them.
Emission lines are distinct coloured lines that appear on a black backdrop and correspond to certain wavelengths of light emitted by an item.
Absorption lines are visible as black bars.

Answer:
The correct answer is option B. From 200K to 400K
Explanation:
Hello!
Let's solve this!
The ideal gas equation is the following PV = nRT
Where the variables are:
P: pressure
T: temperature
V: volume
R: universal constant of ideal gases
n: number of moles
We see in the equation the proportional relationship of volume with temperature.
We deduce that if the volume increases twice, then the temperature increases twice.
The temperature has to be in Kelvin, that's why we chose that answer.
Of the options, the correct answer is option B. From 200K to 400K
