What will most likely happen when stress is applied to an equilibrium reaction? The system will not respond to the stress. The s
steposvetlana [31]

Answer:

The system will change its concentration to shift to a new equilibrium position.

Explanation:

For example  in the Haber Process

N2  +  3H2  ⇄  2NH3

If the pressure is increased the  process will move to the right - to have more NH3 and less of the nitrogen and hydrogen.

Question 1<br> 1 pts<br> How many mols of bromine are present in 35.7g of<br> Tin(IV) bromate?
sleet_krkn [62]

Answer:

n = 0.0814 mol

Explanation:

Given mass, m = 35.7g

The molar mass of Tin(IV) bromate, M = 438.33 g/mol

We need to find the number of moles of bromine. We know that,

No. of moles = given mass/molar mass

So,

n=\dfrac{35.7}{438.33}\\\\n=0.0814\ mol

So, there are 0.0814 moles of bromine in 35.7g of  Tin(IV) bromate.

Suppose 0.035 moles of HCl is dissolved in enough water to produce 750 mL of solution. What is the pH
zhuklara [117]

Answer:

pH = 1.33

Explanation:

Because HCl is a strong acid, each mole of HCl will completely dissociate into H⁺ and Cl⁻ species.

Now we calculate the molar concentration (molarity) of H⁺:

  • Molarity = moles / volume

(750 mL ⇒ 750 / 1000 = 0.750 L)

  • Molarity = 0.035 moles / 0.750 L
  • Molarity = 0.0467 M

Then we calculate the pH of the solution:

  • pH = -log [H⁺]
  • pH = -log (0.0467 M)
  • pH = 1.33

fill in the blanks: label the different parts of the rock cycle where igneous, sedimentary, and metamorphic rock are formed.
Zarrin [17]

Answer:

☞rock cycle

=> The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions.

=> There are three main kinds of rocks: igneous rock, metamorphic rock, and sedimentary rock. ... It can erode into sediment or melt into magma. It is formed under extreme pressure and temperature deep inside mountain chains.
