Some of the negative impact of disruption in water cycle are adverse environment, with affected farming, hydroelectricity, and deforestation.

The water cycle has been operated in the environment for the conversion of water in the different states. The water cycle has been operated with the conversion of water from the water body to the clouds by evaporation.

The evaporated water has resulted in clouds, that have been condensed and precipitated in the form of rain. The water cycle helps in maintaining the water balance in the ecosystem. It made the water available for use as well.

The drought has been the condition of the scarcity of water. In this condition, there has been a disruption of the water cycle. Some of the negative impacts resulting from the disruption of the water cycle are:

Mg is ahead of Al in the electrochemical series and more reactive than Al hence Al does not react with MgCl2.

A chemical reaction is said to have occurred when new substances are formed. The reaction between magnesium chloride  solution and sodium carbonate solution is a double decomposition reaction since the cations exchange anion partners in the product;

MgCl2(aq) + Na2CO3(aq) ------> MgCO3(s) + 2NaCl(aq)

We must note that a single replacement reaction depends on the relative positions of metals in the electrochemical series. Al can react with CuCl2 because Al is more reactive than copper and ahead of Cu in the electrochemical series. On the other hand, Mg is ahead of Al in the electrochemical series and more reactive than Al hence Al does not react with MgCl2.

The 3-dimensional orientation of a sublevel is known as atomic orbital.

In quantum mechanics, Atomic orbitals are locations around an atom's nucleus where electrons are most likely to be at any particular time(specific orbits). These specific orbits exist in levels and can be broken down into sublevels.

Each sublevel has an orbital and it is oriented differently in 3-dimensional space.

The atomic orbital is a mathematical function that depicts how one or two electrons in an atom behave as seen in waves.

Answer: 0.28 mol H2

Explanation:

0.57mol HCl         1mol H2          

                             2mol Hcl

Hydrochloric acid and zinc show the displacement reaction to produce hydrogen gas and zinc chloride. 0.57 moles of hydrochloric acid and excess zinc react to produce 0.28 mol H₂.

A displacement reaction is the removal of one of the elements from the reactant with highly active species of the reactivity species to produce the products. It can be a single or double displacement reaction.

The balanced chemical displacement reaction is given as:

2 HCl + Zn → H₂ + ZnCl₂

Here, two hydrochloric acids react with zinc to form one mole of hydrogen gas and one mole of zinc chloride.

Given,

Hydrochloric acid = 0.57 moles

Using proportions to calculate moles as:

If 2 moles of HCl = 1 mole H₂

Then, 0.57 moles = X moles

X = 0.57 ÷ 2

= 0.28 mol H₂

Therefore, 0.57 mole HCl produces 0.28 moles of hydrogen gas.

The Newton's Second law of motion, also known as The Law of mass and acceleration, derives the given equation in terms of mass, acceleration and force.

It actually states that Force applied on a body is equal to the time rate of change of it's momentum.

Momentum of a body, is the product of it's mass and velocity with which its moving.

This clarifies that objects at rest have zero momentum since they have zero velocity.

If a "source" applies force on an object, it's magnitude would depend on its rate of change of momentum with time.

Since, mass of an object is a fixed entity, so change in momentum would be caused due to change in velocity.

Now, if we happen to have two objects of different mass,

(As, in here, a chair and a large couch) and we have to push them so as to produce the same change in momentum, the force applied on a couch would be more than that applied on the chair.

This is simply because,

Force = mass × acceleration

If acceleration for both the objects is fixed, the force applied differs due to theur difference in mass.

Note here that Force I'd directly proportional to mass.

The greater the mass is, the higher is the force required to produce same acceleration.

Thus, objects with higher mass will require a greater amount of force to have the same acceleration as the object of light weight.

Explanation: The elements in the modern periodic table are arranged in order of their atomic numbers, which is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number.

Explanation:

Answer:

C. give all of the pea plants different amounts of water and count the number of peas that the plants produce

Explanation:

The class wants to design an experiment that answers the question, "What amount of water will cause the plants to produce the greatest number of peas?"

To answer the question, the experiment should show how many peas the plants produce when they are given different amounts of water. The best way to do this would be to give all of the plants different amounts of water and count the number of peas that the plants produce.

To name the binary ionic compounds it is necessary to observe which is the metal and the non-metal that compose them.

This name is made as follows:

An example of this can be seen in the binary ionic composite KCL that receives the name Potassium Chloride, since potassium is the metal and chlorine is the non-metal.

It is important to remember that binary ion compounds are electrically charged ionic molecules formed by a metal and not a non-metal.
