Answer:

It is important to know if a resource is renewable or non-renewable because renewable resources are self-sustaining (unlike non-renewable resources). If a non-renewable resource is used too often, that resource may eventually become non-existant. This can also happen to renewable resources, but it is more difficult.

Antacids, such as Alka-Seltzer, use the reaction of sodium bicarbonate with citric acid in water solution to produce a fizz as f

Alex17521 [72]

Answer:

2.8248 g

Explanation:

First, consider the balanced chemical equation:

$3NaHCO_{3} +C_{6}H_{8}O_{7} --->3CO_{2} +3H_{2}O +Na_{3}C_{6}H_{5}O_{7}\\$

Then we calculate the number of moles in 4.11 g of citric acid:

n(citric acid)= $\frac{4.11g}{192g/mol}=0.0214mol$

According to the balanced reaction, one mole of citric acid produces 3 moles of carbon dioxide. That's 3 times the number f moles of citric acid. So we will do the same with the available number of moles of citric acid.

so n(carbon dioxide) = 0.0214 mol*3=0.0642 mol

mass(carbon dioxide)= mass*molar mass=0.0642 mol* 44g/mol

= 2.8248 g

How many moles of copper(II)sulfate are in in 5.00 L of a 2.00 M solution?

Julli [10]

Answer:

There are 10 moles of copper(II)sulfate.

Explanation:

We know that molarity is a concentration measure that expresses the moles of solute per liter of solution: in this case, being 1.30 molar, there are 1.30 moles of solute in 1 liter of solution. We solve with the following simple rule of three:

1 L solution-----2 moles of copper(II)sulfate

5 L solution----x= (5 L solution x 2 moles of copper(II)sulfate)/1 L solution

<em>x= 10 moles of copper(II)sulfate</em>
