Answer:

6 oxygen atoms

Explanation:

From the equation,

2Fe(OH)₃ → Fe₂O₃ + 3H₂O

From the reactant (left hand side) we have 2 moles of Fe(OH)₃ having (2 * 3 = 6) atoms of oxygen and decomposed to give Fe₂O₃ which contains 3 atoms of oxygen and 3 moles of water that also contains 3 atoms of oxygen.

Since the number of oxygen participating in the reaction is independent on the product (not a reversible reaction) then the total number of oxygen atoms participating in the reaction is 6

Compounds A and B react to give a single product, C. Write the rate law for each of the following cases and determine the units

emmasim [6.3K]

Answer:

Explanation:

Rate laws are mathematical expressions which define the relationship that exists between the rate of a chemical reaction and the concentration of the reacting components. Rate laws take the following form:

$rate = k [A]^{x} [B]^{y} [C]^{z}$ ...

where k = rate constant

[A], [C] and [C] represent the molar concentrations of the reactants

k, x, y, and z are determined experimentally by observing how the rate of reaction changes with the concentrations of the reactants.

If x=1, the reaction is first order for [A]. Also, if y=2, the reaction is second order for [B] and so on...

The overall order of the reaction is the sum of the orders with respect to each reactant. Therefore, the overall order of the reaction is x+y+z.

Can someone help me with my stoichiometry homework, it is due tonight.

AleksandrR [38]

Answer:

1. 1 mole of NaCl.

2. 1 mole of H₂O.

Explanation:

The balanced equation for the reaction is given below:

HCl + NaOH —> NaCl + H₂O

From the balanced equation above,

1 mole of HCl reacted with 1 mole of NaOH to produce 1 mole of NaCl and 1 mole of H₂O.

Next, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above, we can see that 1 mole of HCl reacted completely with 1 mole of NaOH. Therefore, HCl is the limiting reactant and NaOH is the excess reactant since we have 3.6 moles of NaOH.

1. Determination of the amount of NaCl produced from the reaction.

NOTE: The limiting reactant is used to determine the maximum amount produced since all of it is consumed in the reaction.

The limiting reactant is HCl and the amount of NaCl produced can be obtained as follow:

From the balanced equation above, we can see that 1 mole of HCl reacted to 1 mole of NaCl.

Thus, 1 mole of NaCl was produced.

2. Determination of the amount of H₂O produced from the reaction.

From the balanced equation above, it is evident that 1 mole of HCl reacted to produce 1 mole of H₂O.

Thus, 1 mole of H₂O was produced.

What is the ph of a 0. 571 m solution of hydrosulfuric acid, h2s?

Ray Of Light [21]

pH is the potential of the hydrogen in the aqueous solution. The pH of the hydrosulfuric acid is 0.6.

pH is the hydrogen or the hydronium ion concentration in the aqueous solution. The formula to calculate pH is given as,

$\rm pH = \rm - log [H^{+}]$

Since hydrosulfuric acid is diprotic the concentration of the hydrogen ion will be:

$\begin{aligned} \rm [H^{+}] &= 2 \times 0. 571 \;\rm M \\\\&= 1.142\end{aligned}$

Now, pH is calculated as:

$\begin{aligned} \rm pH &= \rm - log [H^{+}]\\\\&= \rm - log [1.142]\\\\&= 0.06\end{aligned}$

Therefore, 0.6 is the pH of the hydrosulfuric acid solution.
