Exothermic reactions release energy. Where is the energy used for these reactions to occur stored? .

Chemistry
1 answer:
Tanya [424]3 years ago

Answer:

In the chemical bonds.

Explanation:

There are different types of chemical bonds, some store a TON of energy while others do not store as much. You can think of it like this: for bonds with low energy, it takes a LOT of force to pull them apart, meaning they are strong bonds. However, this way, you have to put energy into them to break the bonds and form a chemical reaction. This is an endothermic reaction, a reaction that absorbs heat from its surroundings.

Instead, bonds in exothermic reactions are BEGGING to form a more stable bond, and hence store a lot of potential energy. Due to the difficulty of maintaining these bonds, there is a lot of energy put into them. If you break them, however, (exothermic reaction) the energy is released, and hence the exothermic reaction happens.

Hope this helped. Please give Brainliest! :>

As gravity makes an object fall down toward the ground,______ energey becomes kinetics energy
Anton [14]

Answer:

Explanation:

Potential energy is the energy possessed by an object due to its position. For example, when the ball starts to move from its resting position then the ball gains kinetic energy. Thus, as gravity makes an object fall down toward the ground, potential energy becomes kinetic energy.

Answer:

Covalent bonds

Explanation:

Atoms with greatly differing electronegativity values are expected to form..... ... When two atoms each need additional electrons to fill their valence shells, but neither is electronegative enough to steal electrons from the other, they can form another kind of chemical bond called a covalent bond.

Write a balanced half-reaction for the reduction of bismuth oxide ion to bismuth ion in basic aqueous solution. Be sure to add p
Butoxors [25]

Answer:

3H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+6OH^-

Explanation:

Hello there!

In this case, according to the required half-reaction, we start by setting it up from bismuth (V) oxide ion to bismuth (III) ion:

BiO_3^-\rightarrow Bi^{3+}

Thus, next realize that the oxidation state of Bi in BiO3^- is 5+ because oxygen is 2- (-2*3+x=-1;x=-1+6;x=+5), so we obtain:

(Bi^{5+}O_3)^-\rightarrow Bi^{3+}

Thereafter, we realize three water molecules are needed on the right in order to balance the oxygens and consequently 6 hydrogen atoms on the left to balance hydrogen:

6H^++(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+3H_2O

Now, since the balance is is basic media, we add six molecules of hydroxide ions in order to produce water with the hydrogen ones:

6OH^-+6H^++(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+3H_2O+6OH^-\\\\6H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+3H_2O+6OH^-\\\\6H_2O-3H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+6OH^-

Then, we accommodate the waters to obtain:

3H_2O+(Bi^{5+}O_3)^-\rightarrow Bi^{3+}+6OH^-

Best regards!

Varvara68 [4.7K]

Answer:

Anhydride, any chemical compound obtained, either in practice or in principle, by the elimination of water from another compound. Examples of inorganic anhydrides are sulfur trioxide, SO3, which is derived from sulfuric acid, and calcium oxide, CaO, derived from calcium hydroxide

Explanation:

<h3><em><u>examples</u></em><em><u>.</u></em></h3>

1)acid anhydride.

2)basic anhydrides.

<h3><em><u>reactions</u></em><em><u>. </u></em></h3>

1)reaction with water

(CH3CO)2O + H2O → 2 CH3CO2H.

Given the mass of the reactants add up to 49 grams, what is the total mass of the products
valina [46]

If the total mass of the reactants is 49g then the mass of the products also equals 49g.

It is due to the law of conservation of mass.

Mass can neither be created nor be destroyed.
