Answer:

6.19 mol H₂O

Explanation:

4 NH₃ + 5O₂ → 4NO + 6H₂O

First, we convert 70.25 grams of NH₃ into moles, using its molar mass:

70.25 g ÷ 17 g/mol = 4.13 mol NH₃

Then we convert 4.13 moles of NH₃ into moles of H₂O, using the stoichiometric coefficients of the balanced reaction:

4.13 mol NH₃ * $\frac{6molH_2O}{4molNH_3}$ = 6.19 mol H₂O

What example of mixture could be seperated using two or more techniques? Explain your answer

STatiana [176]

You can take two liquids of different densities (how much mass is in a given volume) and pour them into a funnel. An example is oil and water. When the mixture settles, the denser liquid will be at the bottom, and drips through the funnel first. This is a separation that you can just let occur naturally.

ΔU for a van der Waals gas increases by 475 J in an expansion process, and the magnitude of w is 93.0 J.

timofeeve [1]

Complete question:

ΔU for a van der Waals gas increases by 475 J in an expansion process, and the magnitude of w is 93.0 J. calculate the magnitude of q for the process.

Answer:

The magnitude of q for the process 568 J.

Explanation:

Given;

change in internal energy of the gas, ΔU = 475 J

work done by the gas, w = 93 J

heat added to the system, = q

During gas expansion process, heat is added to the gas.

Apply the first law of thermodynamic to determine the magnitude of heat added to the gas.

ΔU = q - w

q = ΔU + w

q = 475 J + 93 J

q = 568 J

Therefore, the magnitude of q for the process 568 J.

There are three sets of sketches below, showing the same pure molecular compound (hydrogen chloride, molecular formula ) at thre

RideAnS [48]

Answer:

The correct answer is - option C.

Explanation:

Given: the melting point of HCl is

-114.8 °C, which suggests that below this temperature HCl will be solid.

and, since the boiling point of HCl is - 85.1 °C. It is also suggested that above this temperature HCl will be gas, Therefore.

Solid -114.8 - Ordered arrangement

Liquid -85.1c - Less orderly arranged

Gaseous - Least orderly arranged

Thus, at —90 °C, HCl will be present 'in the liquid state, At — 1 °C, HCl will be present in the gaseous state and at -129 °C, HCl will be present in the solid-state. So, the molecules will be organized in a more orderly manner .

Thus, the correct answer is - option C

What are the rectants of photosynthesis ?

BabaBlast [244]

Answer:

Light energy, water and carbon dioxide

Explanation:

First, let’s look at the photosynthesis equation:

light energy + water + carbon dioxide —> glucose + oxygen

The reactants are what go in and are used to create the products.

In photosynthesis, light energy from the sun, water and carbon dioxide are used to make glucose and oxygen.

Therefore, the reactants are light energy, water, and carbon dioxide.
