Answer:

Destruction of rocks at convergent boundaries

Explanation:

Duuuuuuuuude. Dude.

Let's think for a sec, because this confused me.

Acid rain is chemical weathering. It has acid in it, so it weathers rocks. (Ewwww.)

Frost wedging is a major duh, because frost can weather rocks.

Oxidation reactions are a yes yes because it becomes oxidized.

Mass box A = 10 grams; Mass box B = 5 grams; Mass box C—made of one A and one B Mass ratio A/B =
LUCKY_DIMON [66]

Answer:

mass ratio of A/B is 2:1

Explanation:

Since the mass of box A = 10g

                mass of box B = 5g

   Mass of box C = mass of box A + mass of box

A ratio compares two quantities. To find the ratio of the two boxes:

  Ratio of A to B = \frac{mass of A}{mass of B}

  Ratio of A to B = \frac{10grams}{5grams} = 2

The mass ratio is 2:1 i.e box A has twice the mass of B

Option E, Real gas particles have more complex interactions than ideal gas particles.

In ideal gases, there is absolutely no interaction between any atoms. At all. Atoms simply don't bump into each other in ideal gases.

Obviously, you know that's unrealistic. In real gases, atoms collide into each other all the time.

The equilibrium constant for the chemical equation is Kp = 5.23 at 191 °C. Calculate the value of the Kc for the reaction at 191
Lapatulllka [165]
To convert from Kp to Kc, you need this formula---> Kp= Kc (RT)^Δn, where Δn= gas moles of product- gas moles of reactants. since you did not give a reaction formula, I can't calculate Δn. but all once you find it out. just plug it. 

Kp= Kc (RT)^Δn------------------> Kc= Kp/[(RT)^Δn]
 Kp= 5.23
R= 0.0821
T= 191 C= 464 K
Δn= ?

Kc= 5.23/ (0.0821 x 464)^Δn= ???

MgNH4PO4•6H2O loses H2O in a stepwise fashion as it is heated. Between 40 degrees celsius and 60 degrees celsius, the monohydrat
tino4ka555 [31]

Answer:

\%\ Composition\ of\ phosphorus=20.00\ \%

Explanation:

The molecular formula of the monohydrate formed = MgNH_4PO_4.H_2O

The molecular mass of the monohydrate formed = Mass_{Mg}+Mass_{N}+6\times Mass_{H}+5\times Mass_O

So, Mass = 24 + 14 + 6 × 1 + 5 × 16 = 155 g

Mass of phosphorus = 31 g

Thus,

\%\ Composition\ of\ phosphorus =\frac{Mass_{phosphorus}}{Total\ mass}\times 100

\%\ Composition\ of\ phosphorus=\frac{31}{155}\times 100

\%\ Composition\ of\ phosphorus=20.00\ \%
