Answer:

Sufficient concentration and correct orientation of particles

Explanation:

The collision theory postulates that, for a chemical reaction to occur, there must be collision between reacting particles.

It implies that the rate of reaction depends on the number of collisions per unit time as well as the fraction that are successful or effective.

For collisions to be effective, there must be proper orientation of the particles and right concentration of the reactants.

  • The number of effective collisions and rate of reaction are directly proportional to the concentration of of the reactants.

Answer:

<em>sufficient speed and correct orientation is correct</em>

Explanation:

A successful collision is one that results in the making of the product(s). Two factors—sufficient energy and correct orientation—must be true for a given collision to successfully result in the production of products. Both factors must be true for a given collision for it to go to completion and form the products.

Answer:

11.61 is the pH of 10.0 mL of a solution containing 3.96 g of sodium stearate.

Explanation:

Concentration of sodium stearate acid : c

Moles of sodium stearate = \frac{3.96 g}{306 g/mol}=0.01294 mol

Volume of the solution = 10.0 mL = 0.010 L

c=\frac{0.01294 mol}{0.010 L}=1.294 M

C_{17}H_{35}COONa\rightleftharpoons C_{17}H_{35}COO^-+Na^+

[C_{17}H_{35}COO^-]=c=1.294 M

C_{17}H_{35}COO^-+H_2O\rightleftharpoons C_{17}H_{35}COOH +OH^-

initially c

Dissociation constant of an acid = K_a=1.3\times 10^{-5}

Expression of a dissociation constant of an acid is given by:  

K_a=\frac{[C_{17}H_{35}COOH][OH^-]}{[C_{17}H_{35}COO^-]}

K_a=\frac{(x)^2\times x}{(c -x)}

1.3\times 10^{-5}=\frac{x^2}{1.294-x}

Solving for x;

x = 0.0041 M

[OH^-]=0.0041 M

The pOH of the solution:

pOH=-\log[OH^-]=-\log[0.0041 M]=2.39

pH = 14 -pOH

pH = 14 - 2.39 = 11.61

11.61 is the pH of 10.0 mL of a solution containing 3.96 g of sodium stearate.

What atom has 8 protons and 10 electrons?
Lorico [155]

Answer:

In your case, you have 8 protons and 10 electrons. This means that the atom will carry a total 2 xx (1-) = 2- net charge. Therefore, you are dealing with an anion that carries a 2- net charge, i.e. it has two more electrons than it does protons.
