<u>Answer:</u> The amount of water produced in the given reaction is 0.692x grams.

<u>Explanation:</u>

Let us assume that the initial amount of acetylene gas given be 'x' grams. Now, to calculate the number of moles, we will use the formula:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}   ....(1)

Given mass of acetylene = x grams

Molar mass of acetylene = 26 g/mol

Putting values in above equation, we get:

\text{Number of moles of acetylene}=\frac{xg}{26g/mol}=\frac{x}{26}mol

The reaction of combustion of acetylene is given by the equation:

2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O

By Stoichiometry of the reaction:

2 moles of acetylene produces 2 moles of water.

So, \frac{x}{26} moles of acetylene will produce = \frac{2}{2}\times \frac{x}{26}=\frac{x}{26} moles of water.

Now, to calculate the amount of water produced, we use equation 1:

Molar mass of water = 18 g/mol

Moles of water = \frac{x}{26}mol

Putting values in equation 1, we get:

\frac{x}{26}mol=\frac{\text{Mass of water}}{18g/mol}

\text{Mass of water}=\frac{x}{26}\times 18=0.692x grams

A negative ion is (larger/smaller) than its parent atom.<br> Why?
Kay [80]

Answer:

When an atom attracts extra electrons it becomes a negative ion. The negative ion is larger than the original atom. The positive nucleus remains the same, with the same attractive force. However, this attractive force is now pulling on more electrons and therefore has less effect.

Or

Positive ions are formed by removing one or more electrons from the outermost region of the atom. The opposite is true of negative ions. When electrons are added to form an anion, the increased electron-electron repulsions cause the electrons to spread out more in space. Thus, anions are larger than their parent atoms.

At equilibrium, ________. At equilibrium, ________. all chemical reactions have ceased the rate constants of the forward and rev
balandron [24]

Answer:

<em>At equilibrium, the rate of the forward, and the reverse reactions are equal.</em>

Explanation:

In an equilibrium chemical reaction, the rate of forward reaction, is equal to the rate of reverse reaction. Note that the reactions does not cease at equilibrium, but rather, the reactants are converted to product, at the same rate at which the product is also being converted into the reactants in the reaction. When chemical equilibrium is reached, a careful calculation of the value of equilibrium constant is approximately equal to 1.

NB: If the value of equilibrium constant is far far greater than 1, then the reaction will favors more of the forward reaction, and if far far less than 1, the reaction will favor more of the reverse reaction.

The power for the first tank is 2kW  and the second tank is 150 kw for the theoretical pumping power lifts a solution with a density of 1200 kg/m³ from a tank to a reservoir.

<h3>What is power?</h3>

Power is the amount of energy in kilowatt which is required to do some work that needs energy known as power it is the multiplication of pressure and the flow of liquid.

Power for the tank = pressure of water × flow of water

Substituting the value,

power = 1 × 2 = 2 kW = P1

power = 10 × 15 = 150 kW = P2

Therefore,  a solution with a density of 1200 kg/m³ from a tank to a reservoir power for the first tank is 2kW  and for the second tank is 150 kW for the theoretical pumping power lifts.
