How many grams of hydrogen gas are needed to completely react with excess nitrogen to produce 26.7 grams of ammonia (NH3)? N2 + H2 → NH3

The process of dissolved solute particles being surrounded by the  water molecules in an aqueous solution is called solvation or hydration.

Solvation occurs when water molecules surround and interact with solute particles, usually ions or polar molecules, forming a stable solution. The water molecules surround the solute particles, with their polar ends facing the solute, creating a layer of water molecules around the solute particles, effectively dispersing and stabilizing them throughout the solution.

Solvation is a key process in many chemical and biological reactions that occur in aqueous solutions, as it helps to facilitate the dissolution of solutes and influences their properties and behavior in solution.

The reaction between potassium (K) and bromine (Br2) produces potassium bromide (KBr).

K + Br2 --> KBr

Now we need to balance the equation. For this, we need to equate the atoms of each element on both sides of the equation.

So in the reactants side:

K - 1

Br - 2

Products side:

K - 1

Br - 1

Let's multiply KBr by 2:

K(s) + Br2 → 2KBr(s)

Now we need to balance K:

2K(s) + Br2 → 2KBr(s)

Let's count again:

Reactants side:

K - 2

Br - 2

Product side:

K - 2

Answer: 41.47°c

Explanation:

0.426 m^3 * 1000 kg/m^3 = 426 kg

0.132 m^3 * 1000 kg/m^3 = 132 kg

T(f) = [(0.132 kg * 95°c) + (426 kg * 25°c)]/ (426 kg + 132 kg)

T(f) = 41.47°c

Metals and molten ionic substances and electrolyte solutions, conduct electricity.

The words that fill in the blanks are;

Metals are conductors because of the presence of free electrons in the metal which are available.

In an ionic solid, the ions are the charge carriers and they are bound up in the lattice making the ionic solid not to be a conductor.

In the molten state, the crystal collapses and the ions are released. Hence, the molten ionic substance is a conductor.

Solutions of electrolytes such as HCl conducts electricity due to mobile ions which are charge carriers in solution. As the concentration of the solution decreases, the number of ions in solution decreases and the conductivity of the solution decreases accordingly.

Mixtures of metals called alloys are still conductors of electricity due to the presence of free electrons.

oxygenicity values

Explanation:

The measurable value upon which Avogadro established his scale is called oxygenicity values.

It is similar to the concept of modern-day  electronegativity in that when two electrified bodies are in contact, the electrical potential between the bodies in contact is a measurable value.

This idea bears a striking similarity to our modern-day concept of electronegativity which is defined as a measure of the ability of an atom in a bond to attract electrons towards itself.

A polymer is any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, which are multiples of simpler chemical units.  Polymers make up many of the materials in living organisms and are the basis of many minerals.

Explanation:

Explanation:

The first man-made polymers were actually modified versions of these natural polymers. Celluloid, the stuff from which silent-movie film was made, was a plastic created from chemically modified cellulose. The first completely synthetic polymer (that is, made by people through chemical synthesis), invented in the early years of the twentieth century, was Bakelite: a plastic made by reacting phenol and formaldehyde under pressure at high temperatures.

Considering the definition of molality, the molality of the KCl in the solution is 6.56 moles/kg.

Molality, or molal concentration, is the amount of a substance dissolved in a given mass of solvent. It is defined as the moles of a solute per kilogram of solvent.

The Molality of a solution is determined by the expression:

molality= number of moles of solute÷ kilograms of solvent

In this case, you know:

Replacing in the definition of molality:

Molality= 1.41 moles÷ 0.215 kg

Molality= 6.56 moles/kg

The molality of the solution is 6.56 moles/kg.

Answer:

CO is considered as a product.

Explanation:

A general chemical equation for a combination reaction follows:

To write a chemical equation, we must follow some of the rules:

The reactants must be written on the left side of the direction arrow.

A '+' sign is written between the reactants, when more than one reactants are present.

An arrow is added after all the reactants are written in the direction where reaction is taking place. Here, the reaction is taking place in forward direction.

The products must be written on the right side of the direction arrow.

A '+' sign is written between the products, when more than one products are present.

For the given chemical equation:

are the reactants in the reaction and  are the products in the reaction.

Hence, CO is considered as a product.

Approximately 166.67 mL of water needs to be evaporated from 250 mL of 1 M Ca(OH)2 to make it 3 M.

The relationship between the initial and final concentrations and volumes must be taken into account.

Given: Initial concentration \((C^1) = 1 M Initial volume (V^1) = 250 mL\)

\((C^2) = 3 M final concentration\)

We can use the equation:

\(C^1 * V^1 = C^2 * V^2\)

Where:

\(V^2\)is the final volume of the solution

Rearranging the equation to solve for V2:

\(V^2 = (C^1 * V^1) / C^2\)

Substituting the given values:

\(V^2 = (1 M * 250 mL) / 3 M\)

\(V^2 = 250 mL / 3\)

\(V^2\) ≈ \(83.33 mL\)

To find the amount of water that needs to be evaporated, we subtract the final volume from the initial volume:

Amount of water to be evaporated = \(V^1 - V^2\)

Amount of water to be evaporated = 250 mL - 83.33 mL

Amount of water to be evaporated ≈ 166.67 mL

Therefore, approximately 166.67 mL of water needs to be evaporated from 250 mL of 1 M Ca(OH)2 to make it 3 M.

Answer:

Explanation:

Answer:

P₂ = 1.12 atm

Explanation:

To find the new pressure, you need to use the Combined Gas Law:

\(\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}\)

In this equation, "P₁", "V₁", and "T₁" represent the initial pressure, volume, and temperature. "P₂", "V₂", and "T₂" represent the new pressure, volume, and temperature. Before plugging the values into the equation, you need to

(1) convert the pressure from mmHg to atm (760 mmHg = 1 atm)

(2) convert the temperatures from Celsius to Kelvin (°C + 273)

The final answer should have 3 sig figs like the given values.

P₁ = 365 mmHg / 760 = 0.480 atm           P₂ = ? atm

V₁ = 5.00 L                                                   V₂ = 2.30 L

T₁ = 20°C + 273 = 293 K                             T₂ = 40°C + 273 = 313 K

\(\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}\)                                              <----- Combined Gas Law

\(\frac{(0.480 atm)(5.00 L)}{293 K}=\frac{P_2(2.30 L)}{313 K}\)                       <----- Insert values

\(0.00819=\frac{P_2(2.30 L)}{313 K}\)                                     <----- Simplify left side

\(2.56 = P_2(2.30L)\)                                      <----- Multiply both sides by 313

\(1.12 = P_2\)                                                  <----- Divide both sides by 2.30

Answer:

\(M_{K^+}=4.0M \\\\M_{SO_4^{2-}}=2.0M\)

Explanation:

Hello!

In this case, since the molarity of a solution is defined as the moles of solute divided by the volume of solution liters, given the mass of potassium sulfate, we can compute the moles by using its molar mass (174.24 g/mol):

\(n_{K_2SO_4}=87gK_2SO_4*\frac{1molK_2SO_4}{174.27gK_2SO_4} =0.50molK_2SO_4\)

Thus, since one mole of potassium sulfate has two moles of potassium ions (K₂) and one mole of sulfate ions, we can compute the moles of each ion as shown below:

\(n_{K^+}=0.50molK_2SO_4*\frac{2molK^+}{1molK_2SO_4}=1.0molK^+\\\\ n_{SO_4^{2-}}=0.50molK_2SO_4*\frac{1molSO_4^{2-}}{1molK_2SO_4}=0.50molSO_4^{2-}\\\)

In such a way, the molarity of each ion turns out:

\(M_{K^+}=\frac{1.0mol}{0.250L}=4.0M \\\\M_{SO_4^{2-}}=\frac{0.5mol}{0.250L}=2.0M\)
