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.

Automobile catalytic converters use a platinum catalyst to reduce air pollution by changing emissions such as carbon monoxide, C

julia-pushkina [17]

Answer: 448 g of $O_2$ will be required to completely react with 784g moles of CO(g) during this reaction.

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} CO=\frac{784g}{28g/mol}=28moles$

The balanced chemical equation is:

$2CO(g)+O_2(g)\rightarrow 2CO_2(g)$

According to stoichiometry :

2 moles of $CO$ require = 1 mole of $O_2$

Thus 28 moles of $CO$ will require= $\frac{1}{2}\times 28=14moles$ of $O_2$

Mass of $O_2=moles\times {\text {Molar mass}}=14moles\times 32g/mol=448g$

Thus 448g of $O_2$ will be required to completely react with 784g moles of CO(g) during this reaction.

inn [45]

Answer:

Correct option -D

Explanation:

Here, A kinetics experiment is set up is set up to collect the gas that is generated from the cacarbonate and methanoic acid.

Among the given conditions, decreasing the particle size of calcium carbonate only increases the production of gas.

Smaller particles of reactant increases the surface area then followed by rate of reaction will be increases it leads to increases the production of gas.

Therefore, the suitable experimental condition most likely to increase the gas production is-

Decreasing the particle size of the $CaCO_{3}$ by grinding it into a fine powder.

Hence, correct option -D.
