In a compound, chemical energy is contained in thea. nuclei of the atoms.
b. unbonded electrons.
c. bonds.
d. movement of the electrons.

Answers

Answer 1
Answer:

The answer is C. bonds. Because chemical energy in compounds is stored in bonds between the molecules involved.

Further Explanation

Energy is the ability to do work, where work is the movement of objects by force. We use energy every day, and energy comes in different forms. Chemical energy is energy stored in chemicals, such as sugar and gasoline.

Chemical energy is energy stored in chemical compounds in the form of bonds between one atom with another atom. Chemical energy is an energy produced in a chemical process. The amount of energy produced depends on the type and amount of reagents in a chemical reaction. Devices that can produce energy from chemical reactions such as batteries and batteries.

Chemical Energy Sources

chemical allergens are stored in molecular bonds and when these bonds break, heat is released or absorbed. These molecules are part of chemical compounds or fuels such as coal, oil, biomass, wood, animal waste, natural gas, food, etc. and they are all sources of chemical energy that generates heat usually through combustion. Chemical energy sources can be classified into two types, depending on whether they are naturally or artificially prepared and depending on their natural state (solid, liquid, or gas):

  • Solid Fuel: wood, coal, lignite, etc.
  • Liquid fuels: gasoline, diesel, alcohol, kerosene, etc.
  • Gas Fuel: natural gas (coal gas, water gas, biogas)

All of these fuels contain hydrocarbons - organic compounds containing carbon and hydrogen - various molecular weights. These hydrocarbons may be alkanes (methane, ethane, propane, etc.), alkenes (ethene, propane, etc.), cycloalkanes, aromatic hydrocarbons, and heterocyclic compounds.

Unlike food webs, food chains

Answers

Food chain follows just one path: along this path it is unambiguous who eats whom.

Food webs don't follow a single path, but are multiple food chains, interconnected.

So, unlike food webs, food chains only follow a single path along which the energy can go. 

How do you find the IUPAC name for a compound like ZnO

Answers

To find the IUPAC name for compounds, you must memorize prefixes and suffixes and other terms in determining or naming a compound. The IUPAC name for compound ZnO is Oxozinc or Zinc Oxide. I hope this helps you on your assignment.

What is an ionice equation with phases for the following chemical reaction: 2HBr(aq)+BaOH2(aq)-->2H2O(l)BaBr2(aq)?

952 grams of ammonium carbonate are dissolved to make 1750 mL of solution

Answers

(%m/v) =mass of solute (in g) / volume of solution (in mL) x 100
       
            = 952 g (NH4)2CO3 / 1750 mL x 100
    
            = 0.544 x 100
       
(%m/v) = 54.4 g /mL or 54.4% concentration of ammonium carbonate

What is the process that changes one set of chemicals into another set of chemicals?a. cohesion
b. hydrogen bonding
c. chemical reaction
d. dissolving

Answers

The process that changes one set of chemicals into another set of chemicals is called a chemical reaction. The correct answer is option c.

A chemical reaction is a process in which chemical bonds between atoms and molecules are broken and formed, resulting in the creation of new substances with distinct chemical properties.

In a chemical reaction, the reactants are the starting substances that react with each other, while the products are the new substances that are formed.

For example: When hydrogen gas reacts with oxygen gas in the presence of a spark or flame, a chemical reaction occurs that produces water as a product:

\rm 2H_2 + O_2 \rightarrow 2H_2O

Therefore, a chemical reaction is the process of transforming one set of chemicals into another set of chemicals. Option c is the correct answer.

Answer: a. cohesion

Cohesion would be the process that changes one set of chemicals into another set of chemicals, as the reactants bond to bring the product, aka product(s).
