Explanation:

[tex] NH_{3}(g) + O_{2}(g) \: → NO_{2} + H_{2}O(g)[/tex]

__↑______↑

8.00 mol | 14.00 mol

________________

[tex] NH_{3}(g) + O_{2}(g) \: → NO_{2} + H_{2}O(g)[/tex]

You can turn this into a system of variables which are solvable.

To do this, create variables for the coefficients of each compound in the reaction respectively.

[tex] a(NH_{3}(g)) + b(O_{2}(g)) → \\c(NO_{2}) + d(H_{2}O(g))[/tex]

Because to be balanced, the count of atoms in each element of the compound correspond to the coefficient of the variable in that compound so that the count of the left (reactant) side is set equal to the right (product) side.

a corresponds to the coefficient of the first compound, b corresponds to the coefficient of the second compound, c corresponds to the coefficient of the third compound, and d corresponds to the coefficient of the fourth compound.

(Reactant = Product)

Reactant: 1a [N] Product: 1c.

Reactant: 3a [H] Product: 2d.

Reactant: 2b [O] Product: 2c + 1d.

Thus the system is:

1a = 1c

3a = 2d

2b = 2c + 1d.

Then just use the substitution methods to solve.

Calcium hydroxide, Ca(OH)2, is an ionic compound with a solubility product constant, Ksp, of 6.5×10–6. Calculate the solubility of this compound in pure water.

Answers

Answer: The solubility of this compound in pure water is 0.012 M

Explanation:

Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as [tex]K_{sp}[/tex]

The equation for the ionization of the  is given as:

[tex]Ca(OH)_2\rightarrow Ca^{2+}+2OH^-[/tex]  

By stoichiometry of the reaction:

1 mole of  [tex]Ca(OH)_2[/tex] gives 1 mole of [tex]Ca^{2+}[/tex] and 2 mole of [tex]OH^-[/tex]

When the solubility of  [tex]Ca(OH)_2[/tex] is S moles/liter, then the solubility of [tex]Ca^{2+}[/tex]  will be S moles\liter and solubility of [tex]OH^-[/tex] will be 2S moles/liter.

[tex]K_{sp}=[Ca^{2+}][OH^{-}]^2[/tex]

[tex]6.5\times 10^{-6}=[S][2S]^2[/tex]

[tex]S=0.012M[/tex]

Thus solubility of this compound in pure water is 0.012 M

can any one solve this quiz plz​

Answers

Answer:

1. It is stoichiometric.

2. O2 is the limiting reactant.

3. 9.0 g of C2H6 remain unreacted.

4. 17.6 g of CO2.

5. 85.2%.

Explanation:

Hello there!

In this case, for the given chemical reaction:

[tex]2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O[/tex]

We can see that:

1. It is stoichiometric and is balanced because the reactants yields the products according to the law of conservation of mass.

2. In this part, it is possible to calculate the moles of ethane by using its molar mass:

[tex]n_{C_2H_6}=15g*\frac{1molC_2H_6}{30.08g} =0.50molC_2H_6[/tex]

And the moles of oxygen by knowing that one mole is contained in 22.4 L at STP:

[tex]n_{O_2}=\frac{1mol}{22.4L} *15.68L=0.7molO_2[/tex]

Thus, by calculating the moles of carbon dioxide product by each reactant, we can identify the limiting one:

[tex]n_{CO_2}^{by\ C_2H_6}=0.50molC_2H_6*\frac{4molCO_2}{2molC_2H_6} =1.0molCO_2\\\\n_{CO_2}^{by\ O_2}=0.70molO_2*\frac{4molCO_2}{7molO_2} =0.4molCO_2\\[/tex]

Thus, since oxygen yields the fewest moles of CO2 product, we infer it is the limiting reactant.

3. In this part, we calculate the mass of C2H6 that actually react first:

[tex]m_{C_2H_6}^{reacted}=0.4molCO_2*\frac{2molC_2H_6}{4molCO_2}*\frac{30.08gC_2H_6}{1molC_2H_6} =6.0gC_2H_6[/tex]

Thus, the leftover of ethane (C2H6) as the excess reactant is:

[tex]m_{C_2H_6 }^{leftover}=15g-6.0g=9.0g6.0C_2H_6[/tex]

4. Since 0.4 moles of carbon dioxide were produced, we use its molar mass to calculate the mass as its theoretical yield:

[tex]m_{O_2}^{theoretical}=0.4molCO_2*\frac{44gCO_2}{1molCO_2}=17.6gCO_2[/tex]

5. Finally, the percent yield is gotten by dividing the actual yield by the theoretical one:

[tex]Y=\frac{15g}{17.6}*100\%\\\\Y=85.2\%[/tex]

Which statement is correct about the rate of most chemical reactions? (5 points)
1.It increases when the concentration of reactants decreases.
2.It does not depend on the concentration of reactants.
3.It increases when the temperature increases.
4.It does not depend on the temperature.

Answers

Answer: 3.It increases when the temperature increases.

Explanation:

The speed of most chemical reactions increase as if the temperature of those same reactions increase as well. This is because a higher temperature allows for reactants to gain the necessary activation energy needed to react.

Enzymes are another reason. Enzymes are catalysts in reactions which reduce the activation energy needed for a reaction to occur and enzymes work best in certain higher temperatures - not too high - so this also leads to the reaction speed increasing due to temperature increases.

Answer:

It increases when the temperature increases.

You need 267 mL of .25M NaCl,
but the only supply of NaCl you
have
is 1.75M NaCl. How do you prepare
the required solution?

Answers

To prepare 267 mL of  0.25M NaCl, we need to take 38.29 mL of 1.75M NaCl solution and add water to it until it makes the final volume up to 267 mL.

We need to prepare the solution of 0.25 M NaCl using 1.75 M NaCl solution, we can use the dilution formula:

[tex]C_1V_1 = C_2V_2[/tex]

where [tex]C_1[/tex], [tex]V_1[/tex] is the concentration and the volume of the initial solution, [tex]C_2[/tex], [tex]V_2[/tex] is the concentration and the volume of the final solution.

We know the final concentration and the final volume that we are required to make. So we can use the above relation to find  [tex]V_1[/tex] of the solution:

[tex]V_1 = (C_2 * V_2) / C_1[/tex]

Now after substituting the values in the relation, we get:

[tex]V_1 = (0.25 M x 267 mL) / 1.75 M\\V_1 = 0.03829 L or 38.29 mL[/tex]

So to prepare 267 mL of  0.25M NaCl, we need to take 38.29 mL of 1.75M NaCl solution and add water to it until it makes the final volume up to 267 mL.

A wave traveling through air meets an object and bounced off its flat surface
at a new angle. Which statement best describes what has happened to the
wave?
A. The object reflected the wave.
B. The object caused the wave to refract.
C. The object absorbed the wave's energy.
D. The object had a slit in its surface that diffracted the wave.
SUBMIT

Answers

When a wave moves through the air and comes into contact with an object, it hits its flat surface from a new angle, causing the wave to refract.

When a wave passes through one material and moves through another, how does its direction change?

When waves cross the boundary between two different materials, their speed changes. For example, light waves refract when they pass through glass to air. Refraction is the effect that causes them to change direction as a result. When water waves move from deep water to shallow water (or the other way around), they refract light.

When a wave traveling through the air comes into contact with an object and bounces off its flat surface, what happens?

When waves bounce back from a surface they can't pass through, this is called reflection. When waves enter a new medium at an angle and begin traveling at a different speed, refraction occurs. Diffraction happens when waves spread out as they travel around impediments or through openings in obstructions.

How is 2Mg+O2= 2MgO balanced?

Answers

Answer:

A half-reaction can be written to represent reduction. At the same time the magnesium atoms become ions, the oxygen atoms become –2 anions by gaining one electron each. By combining these two reactions, we have an oxidation reaction and a re- duction reaction, that are perfectly balanced.

Explanation:

Regroup terms.

2Mg+2O=2mgo

Subtract 2Mg2Mg from both sides.

2O=2mgo-2Mg

Factor out the common term 2.

2O=2(mgo-Mg)

Cancel 2 on both sides.

O=mgo−Mg

How many molecules of nitrogen gas are found in 0.045 L of nitrogen gas at STP

Answers

Answer:

1.2 × 10²¹ molecules

Explanation:

Step 1: Given data

Volume of nitrogen gas (V): 0.045 LConditions: Standard temperature (273.15 K) and standard pressure (1 atm)

Step 2: Calculate the number of moles corresponding to 0.045 L of nitrogen gas at STP
