Answer 1

Answer:

72.2 moles of water is spilled

Explanation:

as moles=mass/mr

so mr of water is 16+2=18

13000/18=72.2

for the second one you can work out the moles of o2

by using moles= number of particles /6.02*10^23

so 4.65*10^26/6.02*10^23

so i got 772.4 on my calculator  to work out the amount of mass

u use the equation mass=moles*mr

so 777.2*16=12435g of oxygen gas

hope it helps :)

A student wrote a chemical equation as shown.

2H₂S+ 302 H₂O + SO₂

What should the student do to balance the equation?

Answers

Answer: The student must add 2 infront of both [tex]H_2O[/tex] and [tex]SO_2[/tex] to make the equation balanced.

Explanation:

A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.

For the given unbalanced chemical equation:

[tex]2H_2S+3O_2\rightarrow H_2O+SO_2[/tex]

On the reactant side:

Atoms of H = 4

Atoms of S = 2

Atoms of O = 6

On the product side:

Atoms of H = 2

Atoms of S = 1

Atoms of O = 3

To balance the equation, a student must balance the atoms by adding 2 infront of both [tex]H_2O[/tex] and [tex]SO_2[/tex]

For the balanced chemical equation:

[tex]2H_2S+3O_2\rightarrow 2H_2O+2SO_2[/tex]

A balloon containing 0.0400 mol of a gas with a volume of 500 mL was expanded to 1.00 L.  Answer the questions and round answers to nearest hundredth place.  Which equation should you use to find the amount of gas added?

B. n₂=V₂n₁/V₁

What is the final number of moles?

0.08  mol

__________________________________________________________

Explanation:

The ideal gas law is Boyle's law, Charles's law, Gay-Lussac's law, and Avogadro's law combined into one equation. Avogadro's law is V₁/N₁=V₂/N₂, Charles's law is V₁/T₁=V₂/T₂, Gay-Lussac's law is P₁/T₁=P₂/T₂, and Boyle's law is P₁V₁=P₂V₂.

For the balloon problem, B is the correct answer because we are looking for the final moles of gas added. Answer B gives the equation that equals n₂, n₂ means final number of moles. The problem gives us initial volume (500 mL), final volume (1 L), and initial moles amount (0.04 mol). Plug these numbers into the equation, n₂=V₂n₁/V₁, using consistent units. Note that V₁=initial volume, V₂=final volume, n₁=initial moles, and n₂=final moles

Which of the following statements regarding carbon is false? Group of answer choices Carbon has the capacity to form single and double bonds. Carbon has the ability to bond with up to six other atoms. Carbon has a tendency to form covalent bonds. Carbon has the ability to bond together to form extensive branched or unbranched "carbon skeletons."

Answers

Answer: The statement, carbon has the ability to bond with up to six other atoms is false.

Explanation:

Carbon is a group 14 element and it is a non-metal. The atomic number of carbon is 6 and its electronic distribution is 2, 4.

This means that there are 4 valence electrons present in it. Also, in order to attain stability a carbon atom forms only covalent bonds, that is, it shares its valence electrons with its own atoms or atoms of other elements.

Carbon has the capacity to form single and double bonds.

As valency of carbon is four so it can only combine to 4 other atoms vis single bond and it cannot bond with up to six other atoms.

Carbon shows the property of catenation, that is, it forms covalent bonds with its own atoms in a large number. So, carbon has the ability to bond together to form extensive branched or unbranched "carbon skeletons".

Thus, we can conclude that the statement, carbon has the ability to bond with up to six other atoms is false.

Answers

Answer: The given decay sequence is [tex]^{238}_{92}U \rightarrow ^{234}_{90}Th + ^{4}_{2}He \rightarrow ^{234}_{91}Pa + ^{0}_{-1}\beta[/tex].

Explanation:

An alpha-particle is a helium atom. Hence, when an alpha decay occurs in [tex]^{238}_{92}U[/tex] then the reaction equation is as follows.

[tex]^{238}_{92}U \rightarrow ^{234}_{90}Th + ^{4}_{2}He[/tex]

Now, in sequence the equation for beta decay is as follows.

[tex]^{234}_{90}Th \rightarrow ^{234}_{91}Pa + ^{0}_{-1}\beta[/tex]

Hence, the sequence will be as follows.

[tex]^{238}_{92}U \rightarrow ^{234}_{90}Th + ^{4}_{2}He \rightarrow ^{234}_{91}Pa + ^{0}_{-1}\beta[/tex]

Thus, we can conclude that the given decay sequence is [tex]^{238}_{92}U \rightarrow ^{234}_{90}Th + ^{4}_{2}He \rightarrow ^{234}_{91}Pa + ^{0}_{-1}\beta[/tex].

Consider the reaction 4FeS2 + 11O2 → 2Fe2O3 + 8SO2. If 8 moles of FeS2 react with 15 moles of O2, what is the limiting reactant? (3 points)


Select one:

a. FeS2

b. Fe2O3

c. O2

d. SO2

Answers

If 8 moles of FeS2 react with 15 moles of O2, the limiting reactant is O2.

WHAT IS LIMITING REACTANT:A limiting reactant is reactant that is totally consumed when the chemical reaction is completed.

According to this question, the following reaction was given: 4FeS2 + 11O2 → 2Fe2O3 + 8SO2.

4 moles of FeS₂ reacts with 11 moles of O₂

This means, 8 moles of FeS₂ will react with (8 × 11/2) = 22 moles of O₂

15 moles of O₂ is available. In comparison with 22 moles, O₂ is in short supply .

Therefore, If 8 moles of FeS2 react with 15 moles of O2, O₂ is the limiting reagent.
