Answer:
I believe the answer your looking for is out of A or B
Explanation:
Option B because if the heat increases its essentially causing the concentration to increase by replacing the weak bonds with stronger ones
In increasing the temperature of a system that includes a reaction in the forward direction that is exothermic, the concentration rises as weak bonds are replaced by stronger ones.
What is the temperature of a system?The average kinetic energy of the atoms or molecules in a system is measured by temperature. No heat is transmitted between two objects in thermal equilibrium, according to the zeroth law of thermodynamics.
In conclusion, as the temperature of the system rises, the concentration rises as weak bonds are replaced by stronger ones.

Where does water pollution come from
Answer:Water pollution can come from a variety of sources. Pollution can enter water directly, through both legal and illegal discharges from factories, for example, or imperfect water treatment plants. Spills and leaks from oil pipelines or hydraulic fracturing (fracking) operations can degrade water supplies.

The density of aluminum is 2.70 g/mL. What is the mass of a 15.9 cm X 11.6 cm X 7.3 cm block of aluminum?
Hi, the answer is 3510g
Step-by-step explanation:-
We know that density of a substance tells us the mass of exactly one unit of volume of given substance. In this question,
Aluminium density = 2.70g/mL
So,
V = L x W x H = 1300 cm³ = 1300 mL
m = D x V = (2.70 / 1300) = 3510g

Explain why there was a reaction between zinc metal and a salt solution of copper sulphate please help me
Answer:
When zinc is added to copper sulphate (CUSO4) solution due to more reactivity of zinc, cooper is replaced by the zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.
6.3 gram of HNO3 as mass of nitrate
Moles of HNO 3
= 6.3/63 = 0.1 moles
HNO3 has 1 atom of H , 1 atom of N , 3 atoms of O
No of atoms = moles of molecule × atomicity of atom × avogadro number
No of atoms of H =0.1×1×6.023×10^23
= 6.023×10^22
No of atoms of N =0.1×1×6.023×10^23
= 6.023×10 ^22
No of atoms of O =0.1×3×6.023×10 ^23
= 18.069×10 ^22

How can the Swartz process be modified to work for bacteria?
Answer:
https://swartzbiotechnologylab.sites.stanford.edu/research
Explanation:
You go to a convenience store to buy candy and find the owner to be rather odd. He allows you to buy pieces in multiples of four, and to buy four, you need $0.23. He only allows you to do this by using 3 pennies and 2 dimes. You have a bunch of pennies and dimes, and instead of counting them, you decide to weigh them. You have 636.3 g of pennies, and each penny weighs 3.03 g. Each dime weighs 2.29 g. Each piece of candy weighs 10.23 g.
Required:
a. How many pennies do you have?
b. How many dimes do you need to buy as much candy as possible?
c. How much should all these dimes weigh?
d. How many pieces of candy could you buy? (number of dimes from part b)
e. How much would this candy weigh?
f. How many pieces of candy could you buy with twice as many dimes?
a. We have 210 pennies
b. We need 140 dimes to buy as much candy as possible.
c. All these dimes should weigh 320.6 g.
d. We can buy 70 pieces of candy.
e. The total weight of the candies will be 2864.4 g
f. Using 3 pennies and 2 dimes as a pack to buy candies we can not buy more pieces of candy because we would need more pennies.
a. To find the number of pennies we need to divide the total mass of pennies ([tex]m_{t_{p}}[/tex]) by the mass of each one of them ([tex]m_{p}[/tex]):
[tex] N = \frac{m_{t_{p}}}{m_{p}} = \frac{636.3 g}{3.03 g} = 210 [/tex]
Hence, we have 210 pennies.
b. We can find the total number of pieces in multiples of four that we can buy with 210 pennies. To buy one piece we need to use 3 pennies and 2 dimes, so the number of total pieces is:
[tex] 3P = 210 [/tex]
Where P is for pennies
[tex] P = \frac{210}{3} = 70 [/tex]
Hence, we can buy a total of 70 pieces in multiples of four candies.
Now, from this total of 70 pieces, we can use the following number of dimes:
[tex] 2D = 70 [/tex]
Where D is for dimes
[tex] D = \frac{70}{2} = 140 [/tex]
Therefore, we need 140 dimes to buy as much candy as possible.
c. The mass of the total amount of dimes ([tex] m_{t_{d}}[/tex]) is:
[tex] m_{t_{d}} = 140*2.29 g = 320.6 g [/tex]
Hence, all these dimes should weigh 320.6 g.
d. We know that we can buy a total of 70 pieces in multiples of four candies (calculated above).
Then, we can buy 70 pieces of candy.
e. Knowing that each piece is a multiple of 4 candies, the weight of the 70 pieces of candy ([tex]m_{c}[/tex]) is:
[tex] m_{c} = 70*4*10.23 g = 2864.4 g [/tex]
f. Since we can buy pieces in multiple of four candies using 3 pennies and 2 dimes if we have now twice as many dimes, we can not buy more pieces of candy because we would need more pennies.

What is light energy absorbed by?
Answer:
I think in the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.
