Answer:

HPRT

Explanation:

HPRT catalyzes the salvage reactions of hypoxanthine and guanine with PRPP to form IMP and GMP

The formation of GMP from IMP requires oxidation at C-2 of the purine ring, followed by a glutamine-dependent amidotransferase reaction that replaces the oxygen on C-2 with an amino group to yield 2-amino,6-oxy purine nucleoside monophosphate, or as this compound is commonly known, guanosine monophosphate.

Answer: The water cycle shows the continuous movement of water within the Earth and atmosphere. ... Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).

Explanation:

Answer:

water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

Explanation:

evaporation, condensation, precipitation, and collection. condensation: this is when water vapor in the air cools down and turns back into liquid water. precipitation: this is when water (in the form of rain, snow, hail, or sleet) falls from clouds in the sky.

good luck :)

hopefully, this helps

have a great day !!

Pb(NO3) + MgI2 = Mg(NO3) + PbI2 is an example of a double-replacement reaction.

Answer: The correct option is C.

Phosphorus has no atmospheric component.

Explanation:

This is because, phosphorus is not in gaseous state but it is liquid at normal temperature, therefore it cannot be found in the air. It is cycle through water,soil or sediments. The major source of phosphorus in the phosphorus cycle is the rock. Rock contain phosphorus and phosphorus I'd gotten from rocks through weathering. Weathering is the disintegration of rocks into sediments or smaller particles. This is released into the soil after weathering.

Answer:

form

Explanation:

Answer:

the elements in a group have similar electron configurations, an elements electron configuration determines its chemical properties, therefore members of a group in the periodic table have similar chemical properties. ... These metals have a single valence electron and are extremely reactive.

Explanation:

The Rf value on the Q is =0.65

The Rf value in the acetaminophen is =0.651

In this question, its identity the Q is probably in the acetaminophen since the value which is used to calculates, and however almost the same, and it is used to ensure the other document which is the substances, that are evaluated.

Answer:

[tex]d=1.5\ g/cm^3[/tex]

Explanation:

Given that,

The mass of the rock, m = 15 g

The volume of the rock, V = 10 cm³

We need to find the density of the rock. The density of an object is equal to the mass per unit volume such that,

[tex]d=\dfrac{m}{V}\\\\d=\dfrac{15\ g}{10\ cm^3}\\\\d=1.5\ g/cm^3[/tex]

So, the density of the rock is equal to [tex]1.5\ g/cm^3[/tex].

Solution :

The reaction :

[tex]$\text{TrisH}^+ + \text{H}_2\text{O} \rightarrow \text{Tris}^- +\text{H}_3\text{O}^+$[/tex]

We have

[tex]$K_a = \frac{[\text{Tris}^-]\times[\text{H}_3\text{O}^-]}{[\text{TrisH}^+]}$[/tex]

     [tex]$=\frac{x^2}{0.02-x}$[/tex]

     [tex]$= 8.32 \times 10^{-9}$[/tex]

Clearing x, we have [tex]$x=1.29 \times 10^{-5}$[/tex] moles of acid

Now to reach pH = [tex]$7.8 (\text{ pOH} = 14-7.8 = 6.2)$[/tex], we must have an [tex]$OH^-$[/tex] concentration of

[tex]$[OH^-] = 10^{-pOH}$[/tex]

          [tex]$=10^{-6.2}$[/tex]

         [tex]$=6.31 \times 10^{-7}$[/tex] moles of base

We must add enough NaOH of 1 M to neutralize the acid calculated above and also add the calculated base.

[tex]$n \ NaOH = 1.29 \times 10^{-5} + 6.31 \times 10^{-7}$[/tex]

               [tex]$=1.35 \times 10^{-5}$[/tex] moles

Vol [tex]$NaOH = 1.35 \times 10^{-5} \text{ moles} \times \frac{1000 \ mL}{1 \ mol}$[/tex]

                 = 0.0135 L

Tris mass [tex]$H^+ = 0.02 \text{ mol} \times 157.6 \ g/mol$[/tex]

                        = 3.152 g

To prepare the said solution we must mix

-- [tex]$3.152 \ g \text{ TrisH}^+$[/tex]

-- [tex]$0.0135 \ mL \ NaOH \ 1M$[/tex]

-- [tex]$\text{Gauge to 1000 mL with H}_2\text{O}$[/tex]

Answer:

Explanation:

We shall find volume of gas at NTP or at 273 K , 760 mm of Hg .

Pressure of given gas = 1.06 x 760 mm of Hg less vapor pressure of water .

= 805.6 - 23.76 = 781.84 mm of Hg

For it we use gas law formula ,

P₁V₁ / T₁ = P₂V₂ / T₂

781.84 x 136.1 / ( 273 + 25 ) = 760 x V₂ / 273

= 128.26 mL .

= 128.26  x 10⁻³ L .

22.4 L of oxygen will have mass of 32 g

128.26 x 10⁻³ L of oxygen will have mass of 32 x 128.26 x 10⁻³ / 22.4 g

= 183.22 mg .

DONT COME ON MY STUFF SAYING THAT I GOT SCHOOL TO DO JUST LIKE YOU AND YOUR GIVING ME IRRELEVANT ANWSERS JUST TO GET POINTS? THATS A WASTE OF MY TIME

Explanation:

Answer:

If a pure compound is distilled, the temperature of the head will be compared to the temperature of the pot. However, if there is an impurity present that strongly interacts with the molecules of the liquid, then the temperature must be increased to increase the vapor pressure of the liquid, eventually to atmospheric pressure, allowing the liquid to boil. Therefore, at the boiling point, the temperature of the pot will be higher than the temperature of the head.

Explanation:

when temperatures increase, pressures also do so, thus reaching boiling points where liquid states become gaseous.

D

Explanation:

I say this because of this that I read. There was a study shown

"Our experiment was a success. We obtained data that answered our problem, “Which substance absorbs the most heat on a hot day? Sand, water, or sand with water?” The results showed that from the twenty-five trials: the cup of sand temperature ranged from 63-68°C, cup of water temperature ranged from 71-77°C, and the cup of sand with water temperature ranged from 66-71°C. Based on our data, our hypothesis was incorrect. We hypothesized that the sand would absorb the most heat since it is darker and less reflective than water; but from our data, water absorbed the most heat. In conclusion, sand absorbed the least amount of heat and water absorbed the most. Next time we want to cool down at the beach, we’ll know where to go!"

This was an experiment that was performed and this is the conclusion

Explanation:

Answer:

-0.0132 atm

Explanation:

Step 1: Calculate the atmospheric pressure change if altitude increases 100. m

Atmospheric pressure decreases by 1.00 mmHg as altitude increases 10.0 m. The decrease in pressure when the altitude increases 100. m is:

100. m × (-1.00 mmHg/10.0 m) = -10.0 mmHg

Step 2: Convert "-10.0 mmHg" to atm

We will use the conversion factor 1 atm = 760 mmHg.

-10.0 mmHg × 1 atm/760 mmHg = -0.0132 atm

Answer:

[tex]MM=150.71g/mol[/tex]

Explanation:

Hello there!

In this case, since the molar masses of chemical compounds allow us to understand the mass they have per mole of substance, for tin oxide, we can see it has one tin atom and two oxygen atoms; thus, for the calculation of this molar mass we multiply the atomic masses by the number of atoms and them add the results up:

[tex]MM=m_{Sn}+2m_O\\\\MM=118.71g/mol+2*16.00g/mol\\\\MM=150.71g/mol[/tex]

Answer:

Mg₃N₂  +  4 H₂SO₄  ⇒  3 MgSO₄  +   (NH₄)₂SO₄

Explanation:

To balance an equation, you need to make both sides of the equation have equal number of each element.  Also, I think that you didn't write the whole equation since the reaction you gave is not likely.

Mg₃N₂  +  4 H₂SO₄  ⇒  3 MgSO₄  +   (NH₄)₂SO₄

Answer:

C. soluble

Explanation:

Remember that a substance that dissolves in a solvent is said to be soluble in that solvent. A substance that does not dissolve in a solvent is insoluble. Process of Dissolving: Solvent particles surround solute particles to form a solution in a process called solvation.
