Answer:
Step-by-step explanation:
check the attachments below for step by step solution
The energy of the reaction is 9 kJ/mol and the reaction is endothermic.
<h3>What is the total energy of the reaction?</h3>
We know that in a reaction, there could be loss or gain of energy. If there is a loss of energy in a reaction, it means that the reaction is exothermic and heat is given out. If heat is gained in the reaction, it means that the reaction is endothermic and heat is absorbed.
Given that;
Energy of the products = 590 kJ/mol
Energy of the reactants = 581 kJ/mol
Using;
Energy of products - Energy of reactants
= 590 kJ/mol - 581 kJ/mol
= 9 kJ/mol

Answer:
x can be any real number
Step-by-step explanation:
5x<=21+2x
Or
3(x+1)>=24
5x-2x<=21
Or
3x+3>=24
3x<=21, i.e x<=7
Or
3x>=21, i.e x>=7
Since we have OR, at least one of them must be true. So x can be any real number.
