Answer:

The correct answer is The energy of the products is less than the energy of the reactants, so energy is released into the surrounding environment.

Explanation:

In exothermic reactions, there is a release of energy in the environment which comes out converted into heat. These types of reactions are the product of a process of transformation of molecules called chemical reaction.

The energy that an exothermic reaction uses to carry out is less than the amount of energy it releases, so as the answer says: This energy is released because the energy of the products is less than the energy of the reactants.

An exothermic change can be for example the processes of condensation and solidification.

liberstina [14]

Answer:

At the end of meiosis, there are four cells, each with 23 chromosomes, for a total of 92 chromosomes split between the four cells.

Explanation:

During meiosis, a diploid cell (46 chromosomes) replicates its DNA (making 92 chromosomes) then undergoes two cell divisions to generate four haploid cells (23 chromosomes).

These haploid cells are the gametes which, during fertilization, fuse to become a zygote with 46 chromosomes.

Write the symbol for the monatomic ion that has a charge of 1– and the condensed electron configuration [ne]3s23p6.

Pani-rosa [81]

Answer is: the symbol is Cl.
[Ne ] 3s² 3p⁶ is electric configuration of noble gas argon, neon (Ne) has10 electrons plus 6 electrons in 3s and 3p orbitals. Neutral atom of monatomic ion that has a charge of 1– has one electron less than argon, so that atom (chlorine) has 17 electrons. Charge of 1- means one electron more for ion: 17 + 1 = 18.

the volume of gas in a container was originally 3.24L, while at standard pressure 1.00 atm. what will the volume be if the press

Simora [160]

Hello!

To solve this problem, we will use the Boyle's Law, which describes how pressure changes when volume changes and vice-versa. The equation for this law is the following one, and we'll clear for V2:

$P1*V1=P2*V2 \\ \\ V2= \frac{P1*V1}{P2}= \frac{3,24 L * 1 atm}{1,20 atm}= 2,7 L$

So, the final volume after increasing the pressure would be 2,7 L. That means that volume decreases when the pressure increases

How many kg of carbon dioxide are used per year to produce their arm and hammer baking soda?

cestrela7 [59]

The complete question would be as follows:

700,000 tons of baking soda are produced per year. How many kilograms of carbon dioxide are used per year to produce baking soda?

We calculate as follows:

CO2(g) + NH3(aq) + NaCl(aq) + H2O -----> NaHCO3(s) + NH4Cl(aq)

700000 tons NaHCO3 ( 907.185 kg / 1 ton ) (1 kmole NaHCO3 / 84.0 kg NaHCO3) x (1 kmole CO2 / 1 kmole NaHCO3) x (44.0 kg CO2 / 1 kmole) = 3x10^8 kg CO2

Hope this answers the question. Have a nice day.
