In the energy graph of an endothermic reaction, the reactants would appear at a lower energy state than the products.
<h3>What is an endothermic reaction?</h3>
An endothermic reaction is a reaction in which heat is absirbed from the surroundings in order for the reaction to proceed.
In endothermic reactions, the heat content of the products is higher than the heat content of the reactants.
Therefore, in the energy graph of an endothermic reaction, the reactants would appear at a lower energy state than the products.

Answer:
2 atm
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 16.0 L
Initial pressure (P₁) = 0.5 atm
Final volume (₂) = 4 L
Final pressure (P₂) =?
The final pressure of the gas can be obtained by using the Boyle's law equation as illustrated below:
P₁V₁ = P₂V₂
0.5 × 16 = P₂ × 4
8 = P₂ × 4
Divide both side by 4
P₂ = 8 / 4
P₂ = 2 atm
Thus, the final pressure of the gas is 2 atm
Answer:
The symbol used to separate the product from each other or reactants from each other is 'plus' (+) .
Explanation:
In chemical equation the symbol used to separate the product from each other or reactants from each other is 'plus' (+) .
While the symbol used to separate the reactant and product from each other is '→'
For example:
Consider the following reaction.
2H₂ + O₂ → 2H₂O
Two moles of hydrogen react with one mole of oxygen to form two moles of water. The both reactant hydrogen and oxygen are separated by the + while reactant and products are separated by → .
Hey there!:
Molar mass CO2 = 44.01 g/mol
44.01 g CO2 ------------------- 6.02*10²² molecules CO2
88 g CO2 ------------------------ y
y = 88 * ( 6.02*10²² ) / 44.01
y = 5.29*10²⁵ / 44.01
y = 1.2 * 10²⁴ molecules of CO2
Answer A
Hope that helps!
