Answer:
If mass remains the same while the volume of a substance changes, the density of the substance will also change.
Explanation:
Selenium and tellurium are rare elements, respectively, in order of crustal abundance. However, polonium, on account of its radioactive decay, is less abundant. The main source of selenium and tellurium is the anode slime deposited during the electrolytic refining of copper.
By stretching a spring, an elastic potential force is generated.
Moles of Carbon dioxide : 13.5
<h3>Further explanation</h3>
Given
4.5 moles propane
Required
moles of Carbon dioxide
Solution
Reaction(Combustion of Propane) :
<em>C₃H₈(g)+5O₂(g)→3CO₂(g)+4H₂O(g)</em>
In a chemical equation, the reaction coefficient shows the mole ratio of the reacting compounds (either in reactants or products)
From the equation, mol ratio of Propane(C₃H₈) : Carbon dioxide(CO₂) : 1 : 3, so mol CO₂ :
= 3/1 x mol Propane
= 3 x 4.5 moles
= 13.5 moles
Answer:
The balanced chemical equation is given as:
Explanation:
When potassium hydroxide reacts with phosphoric acid it gives potassium phosphate and water as a products.
The balanced chemical equation is given as:
According to reaction, 3 moles of potassium hydroxide recats with 1 mole of phosphoric acid to give 1 mole of potassium phosphate and 3 moles of water.
