Explanation:
Objectives and goals serve as a foundation for successful organizations since they establish the business's objective and aid in the identification of required measures. Goals are broad assertions of what you want to achieve, whereas goals are the precise stages or steps you need to take to get there.

How do the Carnivorous plants survive without soil?
Answer:
A simple answer: Carnivores don't eat plants only flesh. So they would not need soil. But it would be hard for Carnivores to get energy because they get energy indirectly from the animals (herbivores) that they eat. How do they get the energy from a herbivore you might ask. Herbivores eat only plants and that gives the herbivore the plant's energy; but if the herbivore gets eaten, it is indirectly transferred into the Carnivore. Hope this helped!!
Carnivore = only feeds on flesh
Herbivore = eats only plants
Omnivore = eats plants and animals/flesh
Which coefficients correctly balance the formula equation below?
AgNO3 + CuCl2 → AgCl + Cu(NO3)2
2, 1, 2,1
1, 1, 3,1
2, 2, 3,1
2, 1, 1,2
Answer:
2, 1, 2,1
Explanation:
The chemical equation of the reaction given in this question is as follows:
AgNO3 + CuCl2 → AgCl + Cu(NO3)2
The reaction is between silver nitrate (AgNO3) and copper (I) chloride (CuCl2) to form silver chloride (AgCl) and copper nitrate (Cu(NO3)2.
However, this above equation is not BALANCED because the number of atoms of each element on both sides of the equation does not equate i.e. are not the same. To balance the equation, we have to make use of COEFFICIENTS, which are numbers used in front of each element in order to balance the equation.
The balanced equation is as follows:
2AgNO3 + CuCl2 → 2AgCl + Cu(NO3)2
From the above balanced equation, we can observe that coefficients used to balance the equation is in the order: 2, 1, 2,1

Which of the following explains the VSEPR geometry of a water molecule?
O It is tetrahedral because there are four bonded pairs around oxygen.
O It is bent because there are four bonded pairs around oxygen.
O It is tetrahedral because there are two bonded pairs and two lone pairs around oxygen.
O It is bent because there are two bonded pairs and two lone pairs around oxygen.
According to VSEPR theory, geometry of water molecule is bent.
Water is a simple molecule consisting of one oxygen atom bonded to two different hydrogen atoms. The molecule adopts a bent structure because of the two lone pairs of electrons on the oxygen atom.The total number of electron pairs in the valence shell of the oxygen atom is 2.The resulting molecular shape is bent with an H-O-H angle of 104.5°.Learn more:

A se ion has a mass number of 77
and a charge of −2
. Determine the number of neutrons, protons, and electrons in this ion.
Answer: The number of protons are 34, number of neutrons are 43 and number of electrons are 36 in the given Se ion
Explanation:
The atom consists of 3 subatomic particles:
Protons: They are positively charged particles present in the nucleus of an atom.Electrons: They are negatively charged particles present in the orbits around the nucleus of an atom.Neutrons: They are neutral particles present in the nucleus of an atom.The mass number is the sum of the number of protons and number of neutrons in the nucleus of an atom. These are known as nucleons
The atomic number is defined as the number of electrons or number of protons present in an atom.
We are given:
A Se ion having mass number 77
Atomic number of Se = 34
Number of protons = 34
Number of neutrons = 77 - 34 = 43
Number of electrons = Atomic number - Charge
Charge = -2
Number of electrons = [34 - (-2)] = [34 + 2] = 36
Hence, the number of protons are 34, number of neutrons are 43 and number of electrons are 36 in the given Se ion
Define the boiling and evaporation using kinetic theory
Answer:
Explanation:
By the kinetic molecular theory (particle model), all matter consists of particles, there are spaces between the particles, the particles are in constant random motion, and there are forces of attraction and repulsion between the particles.
Furthermore, temperature is defined to be a measure of the average kinetic energy of the particles.
Evaporation is a change of phase from liquid to gas explained as follows :
When particles in the liquid phase are heated, they gain kinetic energy and move faster and further apart. Eventually they have enough energy to escape the forces of attraction holding them together in the liquid phase and they move very fast and far from each other and exist in the gaseous phase.
Heavy rains fill a reservoir, causing the dam that holds the water to break. As a result, the areas downstream are suddenly flooded. Which question would a scientist seek to answer?
Answer:
"How to prevent the collapse of the dam that contains water from heavy rains?"
Explanation:
Scientists must work to create innovations capable of bringing benefits to human life and combating disadvantageous and harmful situations. The overflow of dams is something very harmful, as the resulting flooding can cause structural, economic and even public health problems. When this overflow is caused by natural elements, such as heavy rains, the work of scientists in solving these issues is even more important and necessary. In order to resolve the dam failure caused by excess rainwater, scientists must work to answer the following question:
"How to prevent the collapse of the dam that contains water from heavy rains?"
Are your knees the elbows of your legs or are your elbows the knees of your
arms?
A.knees are elbows of your legs
B.elbows are knees of your arms
C.both
Answer:
Both :)
Explanation:
Knees and elbows are the types of joints that are present to move the parts of the body attached to it. The knees are the elbows, and the elbows are the knees.
What are joints?The joints knees and elbows work like the door and allow the movement of the attached body parts in back and forth directions.
The elbow of the arm region and the knee of the leg region have similar functions and are homologous in the function that moves the leg of the lower region and the arm of the upper region.
Therefore, option c. both is the correct option.

Is the following nuclear equation balanced?
No
Yes
Answer:
Yes.
The nuclear equation {226/88 Ra → 222/26 Rn + 4/2 He} is balanced. As we know that an alpha particle is identical to a helium atom. This implies that if an alpha particle is eliminated from an atom's nucleus, an atomic number of 2 and a mass number of 4 is lost.
Therefore, the equation will be reduced to:
226 - 4 = 222
88 - 2 = 86
Hence, the equation is balanced.

When a catalyst is added to a chemical reaction it provides a new reaction pathway that results in a different
Answer: That results in a different ALTERNATE pathway which has a LOWER ACTIVATION ENERGY.
Explanation:
There are many factors that affects a chemical reaction, these include'
--> surface area
--> concentration,
--> temperature,
--> pressure and
--> presence of CATALYST.
A CATALYST is defined as the substance that has the ability to alter the rate of a chemical reaction. Many reaction very slowly when left alone, but become faster when other substances are added. Such substances that merely alter the rate of reactions but do not take part in the reactions are called CATALYSTS.
Activation energy is defined as the energy barrier that must be overcome before a reaction takes place. A catalyst is able to increase the rate of a chemical reaction by decreasing the activation energy of the chemical system.
A catalyst provides an ALTERNATE PATHWAY for the reaction that has a LOWER ACTIVATION ENERGY. When activation energy is lower, more reactant particles have enough energy to react, so the reaction occurs faster.

Calculate the percent water in ZnSO4.7 H20. Show your work.
Answer:
43.8%
Explanation:
Find the sum of the relative atomic mass of all the elements constituting the compound, which is known as the relative formula mass;
[tex]M_{r} = Relative \ formula \ mass \\\\M_{r} \ of \ ZnSO_{4} = 65.4 + 32.1 + 4(16) \\\\M_{r} \ of \ ZnSO_{4} = 97.5 + 64 \\\\M_{r} \ of \ ZnSO_{4} = 161.5 \\\\M_{r} \ of \ H_{2}O = 18 \\\\M_{r} \ of \ ZnSO_{4}.7H_{2}O = 161.5 + 7(18) \\\\M_{r} \ of \ ZnSO_{4}.7H_{2}O = 287.5[/tex]
Then, divide the relative formula mass of all the water by that of the whole compound
w = % water
[tex]w = \frac{7(18)}{287.5} * 100 \\\\w = 0.43826... * 100\\\\w = 43.826...[/tex]
w = 43.8%
