How does Q compare to Keg?
O Q> Keq
O Q< Kea
OQ = Keg
Answer:
Q<Keq
Explanation:
just found out they ask this question twice,
the one on top is right but for the second time this question is asked.
my answer is right for the first time it is asked.
thank you for your time.
In chemical equilibrium, the equilibrium constant is greater than reaction quotient that is Q< Keq.
What is chemical equilibrium?Chemical equilibrium is defined as the condition which arises during the course of a reversible chemical reaction with no net change in amount of reactants and products.A reversible chemical reaction is the one wherein the products as soon as they are formed react together to produce back the reactants.
At equilibrium, the two opposing reactions which take place take place at equal rates and there is no net change in amount of the substances which are involved in the chemical reaction.At equilibrium, the reaction is considered to be complete . Conditions which are required for equilibrium are given by quantitative formulation.
Factors which affect chemical equilibrium are change in concentration , change in pressure and temperature and presence of catalyst.

distinguish between the climates of a coastal location and a location in the center of a large continent.
Answer:
Climatic condition in coastal regions is milder than the climatic conditions in the continental regions.
Explanation:
Climate in coastal regions is mild. It has both hot summers and winters accompanied by sea breezes. Precipitation and humidity is high in coastal areas. Both the summers and winters have a mild temperature range.
While in continental regions both summer and winters undergo extreme conditions. Summers are extremely hot and winters are extremely cold. They have wide range of climatic exposures such as rainy season, autumn season and spring season in between summer and winter season.

What drives this process?
Answer:
D.
Explanation:
The sun makes the land warm, while the water stays colder. This make the warm air rise off the ground and causes the cool are to replace it (making it come from the ocean)
Using m1v1=m2v2,a 0.5 liters of 12 Molarity solution of NaCl was added to a 2.0 liters of water,find out the final molarity of this 2.5 liter solution
Answer:
2.4 M
Explanation:
The dilution formula, M1V1 = M2V2, states that the initial molarity times the initial volume equals the final molarity times the final volume. Plug in the values and solve for M2:
12 M * 0.5 L = M2 * 2.5 L
6 = M2 * 2.5 L
M2 * 2.5 L = 6
M2 = 6 / 2.5 = 2.4 M

Explanation:
how do you determine how many electron energy levels an element has
Answer:36
Explanation:
Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons. Electrons are arranged around atoms in a special way.
Answer:
Explanation:
The maximum number of electrons that can occupy a specific energy level can be found using the following formula: Electron Capacity = 2 n 2 The variable n represents the Principal Quantum Number, the number of the energy level in question.

Complete the following sentence: "During a chemical reaction."
Select one:
O
the number of atoms in the product(s) is less than those of the reactant(s).
O
the mass of the atoms of the product(s) is greater than those of the reactants).
O
a small amount of matter is destroyed during the process
a new substance(s) with the same number of atoms as the initial substance(s) is
tormed
Answer: a new substance(s) with the same number of atoms as the initial substance(s) is formed
Explanation:
Chemical reaction is a reaction in which there is rearrangement of atoms and thus new substance is formed.
According to the law of conservation of mass, mass can neither be created nor be destroyed in chemical reaction. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
A sample of 450.0 g of water is found to contain 180 mg Cd. What is this concentration in parts per million?
Answer:
The correct answer is 399.8 ppm
Explanation:
A concentration in parts per million (ppm) is equal to:
[tex]1 ppm = \frac{1 g solute}{10^{6}g solution}= \frac{1 mg solute}{1 kg solution}[/tex]
Solute: Cd; Mass = 180 mg x (1 g/1000 mg) = 0.18 g
Solvent: Water ; Mass= 450.0 g x (1 kg/1000 g) = 0.45 kg
We have the following total mass of solution:
Mass of solution = Mass of solute + Mass of solvent = 0.18 g + 450 g = 450.18 g = 0.45018 kg
Finally, we divide the mass of solute (in mg) into the mass of solution (in kg) to obtain the ppm (in mg/Kg):
ppm = 180 mg/0.45018 kg = 399.8 mg/Kg = 399.8 ppm

Superscript 32 subscript 15 upper P right arrow superscript 32 subscript 14 upper S i plus superscript 0 subscript negative 1 e. Superscript 32 subscript 15 upper P right arrow superscript 32 subscript 16 upper S plus superscript 0 subscript negative 1 e. Superscript 32 subscript 15 upper P right arrow superscript 32 subscript 14 upper S i plus superscript 0 subscript plus 1 e.
Answer: Superscript 32 subscript 15 upper P right arrow superscript 32 subscript 16 upper S plus superscript 0 subscript negative 1 e.
Explanation:
Beta Decay : It is a type of decay process, in which a proton gets converted to neutron and an electron. This is also known as -decay. In this the mass number remains same but the atomic number is increased by 1.
The general representation of beta minus emission is :

Explanation:
If all people understood the common heritage that we have with the Earth and our environment - namely, that the very atoms that make up our bodies were formed in stars, just like the atoms in rocks, in the atmosphere and in every living thing - would people be more inclined to treat the environment with more care?
Answer:
No
Explanation:
It is one of those harsh realities that no matter how hard we try to connect people to their roots aka make them understand that everything is interconnected like the breathe you throw out is used by plants in photosynthesis, the O2 plants give is used by us. Living beings and Non-living beings are all connected and most humans know about this. But, when it comes time for earning the $$$, people's judgements are often clouded by their greed hence no matter how hard we try to make people understand we are all connected and that they should take care of the environment more, they will likely treat the environment as they always have been: to serve their financial and selfish needs.
TLDR: People are selfish hence probably will not treat environment with more care even if we educate them about our interconnectedness.

A pathogen enters an organism and infects it. Which statement best describes the general effect of the infection on the organism? *
A. The organism experiences a disruption in homeostasis.
B. The organism cannot obtain energy.
C. The organism cannot reproduce.
D. The organism experiences uncontrolled cell growth.
Answer:
Option A, The organism experiences a disruption in homeostasis.
Explanation:
When a pathogen enters the organism’s body, it disrupts its homeostasis. There are several receptors in the body that are responsible for maintaining the stability of the body through negative feedback loop.
A foreign element attaches to the surface of these receptors and hence disrupts their attachment with the probable substance necessary for the regulation of essential body function.
Thus, the temperature regulation get s impaired, hormonal imbalances occur, feeding system disturbs etc.
Hence, option A is correct
