Answer: The answer is liquid

Explanation:

The state of matter consists of particles that are close together in a random pattern is liquid . Hence , Option (B) is correct.

When energy is added or removed to matter, it changes state to form a state of matter.

A state of matter is defined as one of the ways in which matter can interact with itself to form a homogeneous phase.

Therefore , The state of matter consists of particles that are close together in a random pattern is liquid . Hence , Option (B) is correct.

Answer:

Explanation:

Expression for capillary rise is as follows

h = 2T / ρ g r where T is surface tension , ρ is density of liquid and r is radius of capillary tube.

T = .032 J m⁻²

ρ = .71 g / cm³

= 7100 kg / m³

r = .1 x 10⁻³ m = 10⁻⁴ m

h = 2 x .032 / (7100 x 9.8 x 10⁻⁴ )

h = .0092 m

= 9.2 mm .

Answer: think of the Greenhouse effect, carbon gasses in the air cause a warmer environment because there's no way for the gasses to escape Earth's atmosphere, therefore leading to polluted air, and a dirty ecosystem in our wildlife

Answer:

Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. ... So, all solids that possess an appreciable vapour pressure at a certain temperature usually can sublime in air (e.g. water ice just below 0 °C).

Given :

Mass of O₂, m = 25.43 g.

To Find :

How many liters of gas will you have at STP.

Solution :

Molecular mass of O₂, M.M = 2 × 16 gram/mole

M.M = 32 gram/mole

Number of moles is given by :

n = m/M.M

n = 25.43/32 mole

n = 0.79 mole

Hence, this is the required solution.

Answer:

A) Fission

Explanation:

Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

Answer:

Explanation:

as atom contains equal amount of protons and electrons

The information from diagram shows the energy requirements needed in order for a reaction to

occur.

The collision theory states that each and every chemical reaction can occur between particles when the molecules collide each other.

The collision between particles is necessary but it is not sufficient for a reaction to take place. The collisions must be effective.

It is necessary to know the exact nature of an effective collision since this indicates whether particles react with each other and form new products.

According to collision theory, the reaction occur when molecules collide and molecules have sufficient activation energy to cross energy barrier.

Greater the energy, greater will be number of collision. Lesser energy, lesser will be number of collision.

Thus, the given energy diagram shows about the energy required for a reaction to take place.

Explanation:

Difference Between Empirical and Molecular Formulas. The key difference between empirical and molecular formulas is that an empirical formula only gives the simplest ratio of atoms whereas a molecular formula gives the exact number of each atom in a molecule. In chemistry, we often use symbols to identify elements and molecules.

Answer:

True

Explanation:

The Coriolis effect is the deflection of winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere because of Earth's rotation. This statement is true.

Circulating air is deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere as the Earth rotates on its axis. The Coriolis effect refers to this deflection.

Because of the rotation of the Earth, we experience an apparent force known as the Coriolis force. The wind is deflected to the right in the northern hemisphere and to the left in the southern hemisphere as a result of this.

There is no curving of the object's path as measured relative to the Earth's surface because there is no turning of the Earth's surface  underneath a horizontally and freely moving object at the equator.

Thus, There is no Coriolis effect because the object's path is straight.

Answer:The rate of enzyme reaction increases with increase in substrate concentration. Upon saturation of active site of the enzyme with the substrate, there will be no effect on the rate of reaction.

Explanation:

Enzymes are protein molecules secreted by special cells in a living organism. They are organic catalysts responsible for the metabolic reactions that take place in living organisms. Thus, glycolysis, synthesis of proteins and photosynthesis are mediated by numerous enzymes.

Also, enzymes may be classified according to the type of reaction they catalyze. They include: oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases, and translocases.

From the question, catalase enzyme is a type of oxidoreductase enzyme that catalyzes the decomposition of hydrogen peroxide (substrate) into water and molecular oxygen.

The regions on the enzyme into which the substrate molecules fit are known as the ACTIVE SITES of the enzyme.

Substrate concentration is one of the factors that affect enzyme rate of reaction. The enzyme function varies with substrate concentration because the rate of enzyme reaction increases with increase in substrate concentration. Upon saturation of ACTIVE SITE of the enzyme with the substrate, there will be no effect on the rate of reaction.
