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]

What unit is used for atomic mass

Answers

Please mark brainliedt

Answer is daltons
Atomic weight is measured in atomic mass units (amu), also called daltons.




Atomic Mass

Masses of individual atoms are very, very small. Using a modern device called a mass spectrometer, it is possible to measure such minuscule masses. An atom of oxygen-16, for example, has a mass of 2.66 × 10 -23 g. While comparisons of masses measured in grams would have some usefulness, it is far more practical to have a system that will allow us to more easily compare relative atomic masses. Scientists decided on using the carbon-12 nuclide as the reference standard by which all other masses would be compared. By definition, one atom of carbon-12 is assigned a mass of 12 atomic mass units (amu). An atomic mass unit is defined as a mass equal to one twelfth the mass of an atom of carbon-12. The mass of any isotope of any element is expressed in relation to the carbon-12 standard. For example, one atom of helium-4 has a mass of 4.0026 amu. An atom of sulfur-32 has a mass of 31.972 amu.

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.

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].

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.

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

A reaction requires 22.4 L of gas at STP . There are 25.0 L of gas at 101.5 kPa and 373 K.

Which statement is true?

Use the ideal gas law: PV = nRT where R = 8.31 L-kPa/mol-K

A. There is not enough gas for the reaction.

B. Given this information, there is no way to tell if there is enough gas for the reaction.

C. There is excess gas for the reaction.

D. There is enough gas for the reaction.

Answers

Answer:

STP is 101.325 kPa pressure and 273K temperature

Also, at STP, 1 mol of an ideal gas = 22.4 L

Since the question states that 22.4 L are needed at STP, we know that ONE MOLE is needed.  Now, the question is, how many moles are actually present?

V = 25.0 L

P = 101.5 kPa

T = 373K

n = ?

R = 8.31 L-kPa/Kmol

Solving the ideal gas law for n (moles) and comparing that to 1 mole, we have...

n = PV/RT = (101.5)(25.0)/(8.31)(373)

n = 0.82 moles of gas.  THIS IS NOT ENOUGH as it is less than the ONE mole required.

What is the concentration of a solution made by combining 52 grams of NaCH3COO with 150 mL of water?

Answers

Answer: The concentration of a solution made by combining 52 grams of  [tex]NaCH_{3}COO^{-}[/tex] with 150 mL of water is 4.22 M.

Explanation:

Given: Mass = 52 grams

Volume = 150 mL (1 mL = 0.001 L) = 0.150 L

Molarity is the number of moles of a substance present in liter of a solution.

And, moles is the mass of a substance divided by its molar mass.

Hence, moles of [tex]NaCH_{3}COO^{-}[/tex] (molar mass = 82.034 g/mol) is as follows.

[tex]Moles = \frac{mass}{molar mass}\\= \frac{52 g}{82.034 g/mol}\\= 0.633 mol[/tex]

Therefore, concentration of given solution is as follows.

[tex]Molarity = \frac{moles}{Volume(in L)}\\= \frac{0.633 mol}{0.150 L}\\= 4.22 M[/tex]

Thus, we can conclude that the concentration of a solution made by combining 52 grams of  [tex]NaCH_{3}COO^{-}[/tex] with 150 mL of water is 4.22 M.
