The reactions involved in producing larger compounds from smaller compounds is called.
The reactions involved in producing larger compounds from smaller compounds is called anabolism.
It is a biochemical process in which simple compounds join to form larger and complex compounds. This is why it is considered a building-up aspect of metabolism.
Anabolism does not initialize on its own because it is non-spontaneous. It requires energy in initializing. Anabolism is vital for the cell as its development, growth, and maintenance depend on it. Cells also use the anabolic process to make and repair tissues.
For example, the Formation of disaccharides and water by combining sugars, and the reaction of glycerol with fatty acids to form lipids.

Dilution of a buffer solution with a small amount of water will ________ the ph of the solution.
I think the answer would be
Dilution of a buffer solution with a small amount of water will not change the ph of the solution.
Hope this helps
There will be no change in the pH of buffer solution because the pH of a buffer will be constant always. And it makes the solution in a certain pH.
What is buffer?A buffer solution is the solution with constant pH used t maintain the pH of a solution in a certain value. There are both basic and acidic buffers. Basic buffer is made by mixing a weak base with its salt and it maintains the basic pH.
An acidic buffer is made by mixing a weak acid with its salt and used to maintain the acidic pH. Buffer solution will not change in pH on addition of water or acid or any base.
On each dilution the buffer will make the added concentration of acid and base in equal. Like if we added water the release H+ ion will be consumed by the basic buffer and maintain the pH.
Hence, upon dilution by water, the pH of buffer solution does not change.

the pH of a solution of a is increased from 2 to 3 then the concentration of h + ions will become
Answer:
The H+ concentration would decrease by 10 fold. From .01 to .001
Explanation:
This is due to how a pH of 2 is expressed in scientific notation as 10^-2 power when referring to H+ concentration so a pH of 3 would be 10^-3. Hence it would be 10 times smaller in concentration as the power increases to the negative power the smaller the concentration becomes.
What will increase the turgor pressure in a plant
Answer:
Cell expansion and an increase in turgor pressure is due to inward diffusion of water into the cell, and turgor pressure increases due to the increasing volume of vacuolar sap. A growing root cell's turgor pressure can be up to 0.6 MPa, which is over three times that of a car tire.

A solid precipitate is formed from the reaction of lead nitrate and sodium chromate.
Lead chromate (PbCrO4) is the solid precipitate formed from the reaction of lead nitrate and sodium chromate.
A precipitate is a compound that comes out of a liquid solution and it insoluble. The chemical substance which causes the formation of solid to form is called the precipitant. Lead chromate (PbCrO4) is as hard as a brick.
The chemical equation of the reaction is:
Pb (NO3)2 + NA2CrO4 → Pb (CrO4) + 2Na (NO3)
This reaction is known as Double Displacement or Metathesis. Lead chromate emerges as a solid precipitate with a yellow color.

. which type of bond exemplifies a weak chemical bond? covalent bonds in solution hydrogen bonds in solution ionic bonds in solids nonpolar covalent bonds in solids
Hydrogen bond exemplifies a weak chemical bond.
Hydrogen bond is weak because electrons are not transported to form opposing, attracting charges as they are in ionic bonds or shared as they are in covalent bonds.when hydrogen is covalently bonded to a more electronegative atom, that atom pulls the hydrogen's electron away from it, causing it to become attracted to nearby electronegative atoms with unpaired electrons. As a result, hydrogen has a slight positive charge.The electrostatic contact between the atoms caused by the gain or loss of electrons results in the formation of ionic bond which is the strongest bond. The sharing of electrons or the overlapping of two atomic orbitals results in the formation of covalent bonds.When two atoms share electrons equally, a non-polar covalent bond is created.Therefore, among all these bonds hydrogen bond is the weakest.

a cylinder of o2(g) used in breathing by emphysema patients has a volume of 7.00 l at a pressure of 16.0 atm. if the temperature of the cylinder is 32.8°c, what mass (in g) of oxygen is in the cylinder?
Mass of oxygen in cylinder is 142.2 g
The equation of state for a hypothetical ideal gas is known as the ideal gas law, sometimes known as the generic gas equation. It is a good estimate of how many gases behave under various circumstances.PV = nRTGiven,
Volume: 7.00 l
Pressure: 16 atm
temperature: 32.8⁰c = 32.8+273.15 = 305.95K
Mass of oxygen in cylinder = ?
By Ideal gas law,
PV = nRT
PV = (mass/molar mass) RT
molar mass: 32g/mol
R = 0.0826
so,
16 × 7 = (mass/32) × 0.0826 × 305.95
Mass = 142.2g
therefore oxygen present inside the cylinder is 142.2 g in mass.

In my opinion, the channel on Mars was formed by flowing lava because the presence of water is not possible in the intense environment of Mars.
How the channel on Mars was formed?A channel on Mars wasn't done by liquid water but it was built by molten lava according to the study of surface features on Mars. We know that water quantity is very low on the planet Mars so there is very little chance of making of these channels due to flowing of water but we can say that the channels are produced by flowing of lave because there are large number of mountain regions on Mars which erupts lava when the Mars was formed. So there is a strong evidence for the formation of channels on the Mars due to flowing lave.

A kid walking around with a balloon on a summer day when the temperature outside is 300 k contains the volume of 4 l goes into a walk in freezer with a temperature of 275 k to get an ice cream What will be the new volume to the balloon
Answer:
3.67 L
Explanation:
From the question given above, the following data were obtained:
Initial temperature (T1) = 300 K
Initial volume (V1) = 4 L
Final temperature (T2) = 275 K
Final volume (V2) =?
Thus, we can obtain the final volume (i.e the new volume) of the balloon by using the Charles law equation as shown below:
V1 /T1 = V2 /T2
4/300 = V2/275
Cross multiply
300 × V2 = 4 × 275
300 × V2 = 1100
Divide both side by 300
V2 = 1100 / 300
V2 = 3.67 L
Therefore, the new volume of the balloon is 3.67 L
