Answer:

Explanation:

Energy is absorbed to break bonds. Bond-breaking is an endothermic process. Energy is released when new bonds form. Bond-making is an exothermic process.

BRAINLY PLZ

Endothermic process occurs in order to break the bonds in the hydrogen molecules, so it can react with O₂ to form H₂O.

Exothermic reaction is a reaction that is chemical in nature and in which the energy is released in form of heat, electricity or light. Energy is released when the new bonds are formed and this bond making process is an exothermic process.

Endothermic reaction is a chemical reaction that absorbs heat from the surroundings. Energy is absorbed when the bonds breaks and this bond breaking process is endothermic process.

According to question in order to break the bonds in the hydrogen molecule is endothermic process. Energy is absorbed when bonds breaks.

Thus, from the above conclusion we can say that Endothermic process occurs in order to break the bonds in the hydrogen molecules, so it can react with O₂ to form H₂O.

Answer:

Cobaltous Nitride,I think so anyway.......

The formula name for [tex]Co_{3}N_{2}[/tex] is cobalt(II) nitride.

In the compound [tex]Co_{3}N_{2}[/tex], the Co represents the chemical symbol for cobalt, and the N represents the chemical symbol for nitrogen. The subscript numbers indicate the ratio of atoms present in the compound.

To name the compound, we determine the charge of the cobalt ion based on the ratio of cobalt and nitrogen atoms. In this case, since there are three cobalt atoms and two nitrogen atoms, each cobalt atom has a 2+ charge.

Therefore, the correct name for [tex]Co_{3}N_{2}[/tex] is cobalt(II) nitride. The Roman numeral II is used to indicate the cobalt ion's charge.

D. Average Velociry

Explanation:

I majored in Chemistry

Average velocity is the phrase which is  is defined as distance over time for a given period.

Average velocity is a vector quantity and is defined as displacement  which is divided by time. It is expressed in compound units that divide the length by time, such as km/h or mph. The difference between average velocity and average speed is that velocity considers displacement, which has a different concept from distance. Displacement is the difference between two positions in a given direction, so it can be negative to express a reverse direction.

There are different methods to compute average velocity depending on the data available, which include:

Total displacement

Constant acceleration

Two points in a position-time graph

Position function

Answer: 2:2 but if simplified it’s 1:1

Explanation:

Answer:

False

Explanation:

Left:

K = 2 atoms

O = 1 atoms

H = 1 atoms

Right:

K = 2 atoms

O = 1 atoms

H = 2 atoms

O = 1 atoms

As you can see both sides do not have the same amount of atoms, therefore it is not balanced.

The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265

Explanation:

Mike Trout of the Los Angeles Angels has a contract worth $426,500,000

On the other side, you earn $100,000 per year.

To calculate the number of years it would take for you to earn what Mike Trout will earn from his contract, you must divide the amount Mike earned by the amount you earned during a year:

$426,500,000 ÷ $100,000 per year= 4,265

The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265

The correct answer is A. Charging by friction

Explanation

When someone rubs a comb with their hair when they are combing it and the hair sticks to the comb occurs a phenomenon called electrization, in which a neutral body becomes charged or loses an electrical charge (electrons). One way that electrization occurs is through the rubbing of two neutral bodies which causes one to be positively charged and the other negatively causing them to attract each other by magnetism. Therefore, the correct answer is A. Charging by friction

The picture shows that a physical change has taken place which converted ice to water.

Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.

Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.

They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 60g is the mass of  5.00 moles of carbon.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically, the formula for mole can be given as

mole of carbon =given mass of carbon  ÷ molar mass of carbon

number of mole of carbon=  5.00 moles

mass of carbon=?

molar mass of carbon= 12.0107 grams

Substituting the values in above formula we get

5.00 moles  = mass of carbon  ÷12.0107 grams

On calculations, we get

mass of carbon =60g

Therefore, 60g is the mass of  5.00 moles of carbon.
