Answer: -

Water can dissolve other substances. Which factor best contributes to this property of water?

d. Water particles are not fixed in place.

Explanation: -

When a substance like say common salt sodium chloride NaCl is dissolved in water, the water molecules surround the Na⁺ and Cl⁻ which result from dissolving of NaCl in water.

The water molecules by surrounding the Na⁺ and Cl⁻ help in dissolving NaCl.

Thus in order to surround them,the water molecules should not be fixed in their place and be free to move about.

What happens when soluble fiber is mixed with water?

storchak [24]

Answer:

Soluble fiber attracts water and turns to gel during digestion. This slows digestion. Soluble fiber is found in oat bran, barley, nuts, seeds, beans, lentils, peas, and some fruits and vegetables. It is also found in psyllium, a common fiber supplement.:

The decomposition of HBr(g) into elemental species is found to have a rate constant of 4.2 ×10−3atm s−1. If 2.00 atm of HBr are

Dennis_Churaev [7]

Answer:

7,94 minutes

Explanation:

If the descomposition of HBr(gr) into elemental species have a rate constant, then this reaction belongs to a zero-order reaction kinetics, where the r<em>eaction rate does not depend on the concentration of the reactants. </em>

For the zero-order reactions, concentration-time equation can be written as follows:

[A] = - Kt + [Ao]

where:

[A]: concentration of the reactant A at the <em>t </em>time,
[A]o: initial concentration of the reactant A,
K: rate constant,
t: elapsed time of the reaction

<u>To solve the problem, we just replace our data in the concentration-time equation, and we clear the value of t.</u>

Data:

K = 4.2 ×10−3atm/s,

[A]o=[HBr]o= 2 atm,

[A]=[HBr]=0 atm (all HBr(g) is gone)

<em>We clear the incognita :</em>

[A] = - Kt + [Ao]............. Kt = [Ao] - [A]

t = ([Ao] - [A])/K

<em>We replace the numerical values:</em>

t = (2 atm - 0 atm)/4.2 ×10−3atm/s = 476,19 s = 7,94 minutes

So, we need 7,94 minutes to achieve complete conversion into elements ([HBr]=0).

What would the pOH of a solution be if the pH is 9.4

Alika [10]

<h2>Answer:</h2>

pOH = 4.6

<h2>Explanations:</h2>

The sum of pH and pOH of a solution is 14as shown:

$pH+pOH=14$

Given the following parameter

pH = 9.4

Substitute the given parameters into the formula to have:

$\begin{gathered} 9.4+pOH=14 \\ pOH=14-9.4 \\ pOH=4.6 \end{gathered}$

Hence the pOH of the solution of pH of 9.4 is 4.6
