Answer:Chemical energy

Explanation:Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. Chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car's engine.

The type of energy which  is stored in fuels such as gasoline and batteries is chemical energy.

Energy which is stored in the chemical bonds of chemical compounds is called chemical energy.Chemical energy is released during the occurrence of chemical reaction.Reactions wherein energy is given out in the form of heat is called exothermic reactions.

Chemical energy can be converted to other forms of energy like electrical energy during the process of electrolysis and to thermal energy as in the case of thermal engines.

It can also be converted to kinetic energy during explosions . It is stored in batteries, coal, biomass, food, vehicle air bags,etc.

Answer:

Their components

Explanation:

It's simple enough, the components in carbon dioxide and carbon monoxide both have at least one carbon and one oxygen atom. However, they differ because their amount in the molecules is different, and that is because of their covalent bonds. Carbon dioxide has to double electron bonds while carbon monoxide has a rare triple electron bond.

Answer:

The total weight of both object is 78.56 kg.

Explanation:

Given data:

Mass of object A = 45.1 kg

Mass of object B = 33.46 kg

Total weight of object = ?

Solution:

Total weight of both subject must be the sum of weight of object A and B.

Total weight of objects = weight of object A + weight of object B

Now we will put the values of mass of object A and B.

Total weight of objects = 45.1 kg + 33.46 kg

Total weight of objects =78.56 kg

Thus the total weight of both object is 78.56 kg.

Explanation:

Electronegativity is an idea put forward by Linus Pauling to explain the fact that in a molecule, one atom may attract the shared electrons of the bond closer to itself than the other.

Hence electronegativity is defined as the power of an atom in a molecule to attract electrons to itself.

Pauling originally described electronegativity as a relative quantity. It depends on the electronegativities of the atoms in the molecule. However, some methods have sought to measure the absolute electronegativity of a free atom.

A bond is polar when the atoms that make up the bond have a significant difference between the atoms of the molecule.

However, a molecule may possess polar bonds but may not have an overall dipole moment owing to the shape of the molecule.

For instance, CCl4 has four polar C-Cl bonds but the overall molecule is non polar because due to the fact that the molecule is tetrahedral in shape and highly symmetrical hence the individual dipoles cancel out.

THE ANSWER IS C

Explanation:

In a decomposition chemical change, NaCl might form sodium and chlorine , hence option C is correct.

Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.

There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.

There are three types of chemical changes:

1) inorganic changes

2)organic changes

3) biochemical changes

During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

Answer:

Frequency =0.634×10¹⁵ s⁻¹

Explanation:

Given data:

Wavelength = 4.73×10⁻⁷ m

Frequency = ?

Solution:

Formula:

speed of light = wavelength× frequency

speed of light = 3×10⁸ m/s

Now we will put the values in formula.

3×10⁸ m/s = 4.73×10⁻⁷ m × frequency

Frequency = 3×10⁸ m/s /4.73×10⁻⁷ m

Frequency =0.634×10¹⁵ s⁻¹

s⁻¹ = Hz

Frequency =0.634×10¹⁵ Hz

Answer:

1(a) Second order

1(b) 44.0 minutes

2(a) Ea, forward = 85.6 kJ/mol

Ea, reverse = 60.1 kJ/mol

3) k = 9.47 M⁻¹s⁻¹

Explanation:

1(a) We are given mass of product vs time.  We need to find the concentration of reactant.

For example, at t = 0 min, there is 0 g of product.  Therefore, there is 22.9 g − 0 g = 22.9 g of reactant.  The molar mass is 60 g/mol, so there is (22.9 g) / (60 mol/g) = 0.382 mol.  The volume is 1.0 L, so the concentration is (0.382 mol) / (1.0 L) = 0.382 M.

Next, we'll graph [A] vs time, ln[A] vs time, and 1/[A] vs time.

From the graphs, we can see that 1/[A] is linear.  That means the reaction is second order.

1(b) The slope of the line is equal to the rate constant k.

k = 0.0596 M⁻¹min⁻¹

The half life is:

t = 1/(k [A₀])

where [A₀] is the initial concentration of reactant.

t = 1 / (0.0596 M⁻¹min⁻¹ × 0.382 M)

t = 44.0 min

(Notice the mass of product approximately doubles from t = 20 min to t = 45 min.  This confirms that the half life is about 44 minutes.)

2(a) To make an Arrhenius graph, we need to graph ln(k) vs 1/T, where T is temperature in Kelvin.  We'll make two graphs, one for ka (the forward reaction) and one for kb (the reverse reaction).

The slope of each line is -Eₐ/R, where R is the gas constant.  For the forward reaction:

Eₐ = -8.314 × -10300 = 85,600 J/mol = 85.6 kJ/mol

For the reverse reaction:

Eₐ = -8.314 × -7227.6 = 60,100 J/mol = 60.1 kJ/mol

2(b) Make a graph showing the energy changes as the reaction goes from the reactants to the products.  The difference between the reactants and the highest point is the forward activation energy.  The difference between the products and the highest point is the reverse activation energy.

3) Like problem #1, we're going to graph [A], ln[A], and 1/[A] vs time.

Once again, 1/[A] vs t is linear, so this is a second order reaction.

The rate constant is the slope of this line, so k = 9.47 M⁻¹s⁻¹.

Answer: A

Explanation:

Robert Hooke discovered the cell. Cells are the highest level of organization in a living organism. so, option A is correct.

Cell is the smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. It is a small unit of organism containing nucleus.

The cell membrane, the nucleus, and the cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates how substances enter and exit the cell.

After using a very early microscope to examine a piece of cork, Robert Hooke proposed the name "cell" in 1665, derived from the Latin cella, which means "storeroom or chamber." It is also claimed that he believed the rectangular chambers to resemble some monastic cells.

Thus, option A is correct.
