What exactly are you asking
Answer:
7.28 mol Na2SO4
Explanation:
Since it is already in moles, all we have to do is use a molar ratio
A molar ratio is the proportions of reactants and products using the balanced equation. When writing a mole ratio, the given information must cross out with the right thing.
7.28 mol H2SO4 * 1 mol Na2SO4/1 H2SO4 = 7.28 mol Na2SO4
*notice how the H2SO4 crosses out
Answer:
hexaaquairon(III) trinitrate
<h3><u>Answer</u>;</h3>
<h3><u>Explanation</u>;</h3>
- Elements in the periodic table are classified into various categories including alkali metals, alkaline-earth metals, halogens, and noble gases among others.
- <u>Alkali metals are Group 1 elements in the periodic table.</u> They comprise of elements lithium (Li) through francium (Fr). They have similar characteristics and behavior.
- <u>Halogens is another category of elements which is a subset of the nonmetals.</u> They comprise group 17 of the periodic table, from fluorine (F) through Astatine (At). These elements are chemically reactive and reacts with other elements such as group 1 and group 2 element.
Answer is 231.8 K
<em>Explanation</em>
We can use Charle's law to solve this problem.
<span>Charle's law says
"at a constant
pressure, the volume of a fixed amount of gas is directly proportional to its
absolute temperature".
V α T
Where V is the volume and T is the temperature
in Kelvin of the gas. We can use this for two situations as,
V</span>₁/T₁ = V₂/T₂<span>
</span>V₁ = 1.00 L<span>
T</span>₁ =
?<span>
V</span>₂ = 1.10 L<span>
T</span>₂ = 255 K (Since the unit of the given temperature is missing in the question, thought that the given temperature is in Kelvin)<span>
<span>
By applying the
formula,
</span>1.00 L / </span>T₁ = 1.10 L / 255 K
<span>
</span>T₁ =
(1.00 L / 1.10 L) x 255 K<span>
</span>T₁ = 231.8 K
<span>
Hence, the initial temperature is 231.8 K.

Assumption : the pressure of the gas is a constant.
