It will increase by a factor of four.

Answer:

The reaction rate will be multiplied by four.

Explanation:

The reaction rate is the measure of how fast a reaction is happening, and it can be calculated by how fast the reactants are disappearing, or how fast the products are being formed.

For a generic reaction:

A → B + C

The rate (r) is:

-r = k*[A]ⁿ

The minus signal refers to the disappearing of the reactant, k is the velocity constant of the reaction, and n is the reaction order. So, for a second-order reaction:

-r = k*[A]²

If the concentration of A is doubled: [A]' = 2[A]

-r' = k*(2[A])²

-r' = k*4*[A]

-r' = 4*k*[A]

-r' = 4*(-r)

Which of the following statements is always TRUE for the freezing of water?
Rom4ik [11]

ΔG > 0 is always true for the freezing of water.

Explanation:

  • The freezing of water is only spontaneous when the temperature is fairly small. Over 273 K, the higher value of TΔS causes the sign of ΔG to be positive, and there is no freezing point.
  • The entropy decreases as water freezes. This does not infringe the Thermodynamics second law. The second law doesn't suggest entropy will never diminish anywhere.
  • Entropy will decline elsewhere, provided it increases by at least as much elsewhere.

Plz answer thx<br><br><br> ​How many moles are in 2.5 x 10^18 grams of water?
alex41 [277]

Answer:

1.39\times 10^{17} moles of water in 2.5\times 10^{18} g of water.

Explanation:

Mass of water = m = 2.5\times 10^{18} g

Molar mass of water = M = 18 g/mol

Moles = n = \frac{m}{M}

n=\frac{2.5\times 10^{18} g}{18 g/mol}=1.39\times 10^{17} moles

So, there are 1.39\times 10^{17} moles of water in 2.5\times 10^{18} g of water.

State and explain the observations when chlorine gas is bubbled through a solution of
natta225 [31]

Answer:

A reduction-oxidation (redox) reaction will occur.

Chlorine gas (Cl2) will accept electrons to form Cl- ions.

The Iron(II) ions (Fe2+) will lose electrons to form Fe3+ ions. (Iron (III) ions)

Fe2+ ions are green, while Fe3+ ions are yellow,

so the observation will be the solution turning from green to yellow.
