Answer:

187 moles NH₃

Explanation:

To find the amount of ammonia formed, you need to multiply the given value by the mole-to-mole ratio consisting of both relevant molecules. The mole-to-mole ratio is made up of the molecules' coefficients in the balanced equation. The desired unit should be placed in the numerator of the ratio. The final answer should have 3 sig figs to reflect the lowest amount of sig figs among the given values.

Answer:

Complete combustion

Explanation:

To solve such this we must know the concept of combustion reaction. Therefore the products of complete combustion are carbon monoxide, carbon and water.

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved.

There are so many types of chemical reaction reaction like combustion reaction, acid base reaction, double displacement reaction, combustion reactions. The products of complete combustion are carbon monoxide, carbon and water. Large amount of heat is also released in combustion reaction

Therefore the products of complete combustion are carbon monoxide, carbon and water.

The trend in electronegativity values across period 3 from sodium to chlorine is that sodium with 11 protons is the least electromagnetic element and chlorine with 17 protons is the most electronegative element.

It should be noted that electronegativity simply means a chemical property that describes the tendency of an atom to attract elements towards it.

In this case, the trend in electronegativity values across period 3 from sodium to chlorine is that sodium with 11 protons us the least electromagnetic element and chlorine with 17 protons is the most electronegative element.

The rheo leaf peel will lose water by osmosis and become flaccid. If the rheo leaf was boiled, this would not happen.

Across living membranes, water moves from a region of high to a region of low water potential.

Concentrated sugar solutions have low water potential when compared to the cell sap of the cells of rheo leaf peel. Thus, water will move from the rheo leaf peel to the sugar solution.

This will result in the wilting of the leaf peel.

If the leaf peel is boiled, the membranes in the cells die and can no longer function as a selectively permeable interface.

In an endothermic reaction, products are higher in potential energy and  less stable than reactants.

Endothermic reactions are those reactions that do not release heat but absorb heats, that's why the products are of higher potential energy and due to this they are less stable.

Thus, the correct option is C, higher; less.

The concentration (molarity) of the Ca(OH)₂ solution needed to neutralize 31.5 mL of 0.1 M HC₂H302 solution is 0.162M (option D).

The molarity of a solution can be calculated using the following formula:

CaVa = CbVb

Where;

31.5 × 0.1 = 19.4 × Cb

3.15 = 19.4Cb

Cb = 0.162M

Therefore, the concentration (molarity) of the Ca(OH)₂ solution needed to neutralize 31.5 mL of 0.1 M HC₂H302 solution is 0.162M.

Answer:

=> 119.4597 g

Explanation:

From our question, we have been provided with the molarity of the resultant solution.

We know that, molarity of a solution is contained in 1 L or 1000 cm³ of solution.

Hence we have 1.50 moles in 1000 cm³.

Also, we know that, 1 cm³ equivalent to 1 g for water.

Thus, from our question we have 995 cm³ of water.

Lets now solve our problem;

1.5 moles are contained in 1000 cm³

x moles are contained in 995 cm³

Cross multiply

[tex]x \: moles \: = \frac{(995 {cm}^{3} \times 1.5 \: moles )}{(1000 {cm}^{3} )} \\ = \frac{1492.5 \: moles}{1000} \\ = 1.4925 \: moles[/tex]

1.4925 moles of NH4NO3 are required to be dissolved in water.

To find the mass of solute (NH4NO3) we use the formula;

Mass = RFM (Relative Formula Mass) x Number of moles

[tex] = 80.04 \: \frac{g}{mol} \times1.4925 \: mol \\ = 119.4597 \: g [/tex]

Therefore the mass of NH4NO3 needed to be dissolved in 995 g of water is 119.4597 g
