How many moles of sulfuric acid (H2SO4) are present in 500.0 mL of 0.15 M H2SO4 solution?

Answers

Answer:

Number of moles = 0.075 mol

Explanation:

Volume = 500.0 mL = 0.5 (Converting to L by dividing by 1000)

Molarity = 0.15 M

Number of moles = ?

The relationship between the quantities is given as;

Molarity  = Number of moles / Volume

Number of moles = Molarity * Volume

Number of moles = 0.15  * 0.5

Number of moles = 0.075 mol

Briefly describe each of the suns layers. I’ll give brainless

Answers

Answer:  The inner layers are the Core, Radiative Zone and Convection Zone.

The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona.

Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun.

The corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more.

The chromosphere is a layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the chromosphere varies between about 4000 K at the bottom (the so-called temperature minimum) and 8000 K at the top (6700 and 14,000 degrees F, 3700 and 7700 degrees C), so in this layer (and higher layers) it actually gets hotter if you go further away from the Sun, unlike in the lower layers, where it gets hotter if you go closer to the center of the Sun.

The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that. The temperature in the photosphere varies between about 6500 K at the bottom and 4000 K at the top (11,000 and 6700 degrees F, 6200 and 3700 degrees C)

For the balanced equation shown below, how many moles of H2O will react with 9 moles of N2?
N2 + 4H2O --> 2H2O2 + N2H4

Answers

Answer:

36 mole of H20

Explanation:

N2 + 4H2O --> 2H2O2 + N2H4

H20        :       N2

4             :        1

x             :        9

cross multiplication

so,

= 9x4/1 = 36 mole of H20

Can i titrate a solution of unknown concentration with another solution of unknown concentration and still get a meaningful answer

Answers

Answer:

No, I don't think so at least

Explanation:

In chemistry, you do calculations to find the concentration of a solution with another solution of KNOWN concentration. Without concentrations of either solution, were would you get values from? Where would you start? :3

You can not titrate  a solution of unknown concentration with another solution of unknown concentration and still get a meaningful answer.

Titration involves the standardization of unknown solution using a standard solution. By this definition, titration must involve a standard solution.

Since the two unknown solutions are not standardized, we can never get a meaningful answer because we can not be able to perform any calculation unless we have a standard solution.

How much energy is released when 67.04g of phosphorous is reacted with 10.20g of chlorine? ___ P + ___ Cl2 ___ PCl3 ΔH = -574 kJ

Answers

Answer:

26.78 kJ

Explanation:

To solve the problem, we have to first write the stoichiometric coefficients in the chemical equation:

2P + 3Cl₂ → 2PCl₃

With these coefficients, we have the same number of atoms of each chemical element on both sides: 2 atoms of P, 6 atoms of Cl.

According to the equation, 2 moles of phosphorous (P) react with 3 moles of chlorine (Cl₂), and 574 kJ of energy are released. We have to figure out which is the limiting reactant. For this, we convert the mass into moles by using the molar mass(MM):

MM(P) = 30.9 g/mol

67.04 g P/(30.9 g/mol) = 2.17 mol P

MM(Cl₂) = 35.4 g/mol x 2 = 70.8 g/mol

10.20 g Cl₂/(70.8 g/mol) = 0.14 mol Cl₂

Now, we multiply the actual moles of P (the amount we have for the reaction) by the stoichiometric ratio given by the chemical equation (3 mol Cl₂/2 mol P):

2.17 mol P x (3 mol Cl₂/2 mol P) = 3.25 mol Cl₂

To completely react 67.04 g P, we need 3.25 mol of Cl₂, and we have only 0.14 moles of Cl₂, so the limiting reactant is Cl₂.

Now, we use the limiting reactant to calculate the energy released from the reaction. The energy released per mole of Cl₂ is:

ΔH/(3 mol Cl₂) = -574 kJ/3 mol Cl₂= 191.3 kJ/mol Cl₂

Finally, we multiply the energy released per mole of Cl₂ by the number of moles of Cl₂ we have:

0.14 mol Cl₂ x 191.3 kJ/mol Cl₂ = 26.78 kJ

In a closed system for the reaction: A (g) + 2B (g) → AB₂ (g) The rate of the reaction increases when there is
A) an increase in pressure
B) an increase in the reaction vessel
C) a decrease in the concentration of A
D) an increase in surface area of A

Answers

Answer: D

Explanation: an increase in surface area of A

Please Help I need to finish this by the end of the day!

Answers

Answer:

C

Explanation:

If I am not mistaken, due to the conservation of mass, whatever mass is on the side of the reactants should be the same for the product side.

This means

218.76g+53.96g = 272.72g

272.72g-266.66g = 6.06g

So the answer should be C

Consider this reaction: NH4+ + HPO42− → NH3 + H2PO4−

Which is the conjugate base?

NH4+

NH3

HPO42–

H2PO4–

Answers

The NH3, as it was the acid in the beginning and donated a proton to become more basic.

The conjugate base is formed when an acid loses its hydrogen or proton. In the reaction between ammonium ion and hydrogen phosphate, HPO₄²⁻ is the conjugate base. Thus, option C is correct.

What is a conjugate base?

Conjugate bases are formed when the substance accepts or absorbs the proton or the hydrogen ion from the acids in the solution. It can be said as a base with an added hydrogen ion to it.

The chemical reaction of the acids and the bases has been shown as,

NH₄⁺ + HPO₄²⁻ → NH₃⁺ +  H₂PO₄⁻

From the reaction, it can be said that ammonia donated its proton, whereas HPO₄²⁻ accepted hydrogen ions from the acid.

Therefore, HPO₄²⁻ has been the conjugate base in the given chemical reaction.
