The reaction is exothermic because the total bond energy of the reactants is less than the total bond energy of the products is true about change in bond in Exothermic reaction.
<h3>What is an Exothermic reaction?</h3>
An Exothermic reaction in thermodynamics is a type of reaction that released energy from the system of reaction to it's surroundings which can be inform of light, heat or even electricity or sound.
Exothermic reaction has net negative standard enthalpy change.
Therefore, The reaction is exothermic because the total bond energy of the reactants is less than the total bond energy of the products is true about change in bond in Exothermic reaction

Which chemical equation represents a redox reaction?
Answer:
12 moles H

O
Explanation:
Your tools of choice for stoichiometry problems will always be the mole ratios that exist between the chemical species that take part in the reaction.
As you know, the stoichiometric coefficients attributed to each compound in the balanced chemical equation can be thought of as moles of reactants needed or moles of products formed in the reaction.
In your case, the balanced chemical equation for this synthesis reaction looks like this
2
H
2(g]

Notice that the reaction requires
2
moles of hydrogen gas and
1
mole of oxygen gas to produce
2
moles of water.
This tells you that the reaction produces twice as many moles of water as you have moles of oxygen gas that take part in the reaction.
You know that your reaction uses
6.0
moles of oxygen. Assuming that hydrogen gas is not a limiting reagent, you can say that the reaction will produce
6.0

Answer:
C) The same amount of energy
Explanation:
A bomb calorimeter is an equipment used to measure the amount of heat released or absorbed by a chemical reaction. This instrument is hermetic and has thermal insulation, which means that the system doesn't change heat with the surroundings.
So, by the difference of the temperature measured on the system (ΔT), the mass of a solution (m) and the specific heat of water (c) it's possible to calculate the heat in a reaction that occurs in aqueous solution, by the equation below:
Q = mxcxΔT
The heat, or the energy, of the reaction doesn't depend on where the reaction is happening, so the amount of energy measured on the bomb calorimeter will be the same in our body.
Answer:
<h2>The answer is 1.99 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of acid = 60.19 g
volume = 30.2 mL
The density is
We have the final answer as
<h3>1.99 g/mL</h3>
