True or false: This balanced equation shows the combustion of ethane: 2C2H6 + 7O2 → 4CO2 + 6H2O

Chemistry
1 answer:
MakcuM [25]3 years ago
5 0

2C2H6 + 7O2 → 4CO2 + 6H2O

C2H6 is ethane,

Ethane reacts with oxygen, so it is the combustion.

The equation is balanced.

Answer is True.

Balanced chemical equation for the decomposition of solid sodium sulfide in aqueous solution.
Oliga [24]
<h3>Answer:</h3>

Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)

<h3>Explanation:</h3>

We need to know:

<h3>What are decomposition reactions?</h3>
  • Decomposition reactions are type of reactions in which a compound is broken down into two or more products.
  • When a soluble substance or a compound is dissolved in water it forms an aqueous solution.
  • When this happens the soluble compound such as ionic compounds ionizes to form ions.
  • This is an example of decomposition reaction, since the ionic compound decomposes it ions making it.
  • For example, sodium sulfide is an ionic compound that ionizes in water to form sodium and sulfide ions.
  • That is;

Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)

A sample of hydrogen gas has an initial pressure of 2.86 atm and an initial volume of 8472 mL If the volume of the
Oliga [24]
<h3>Answer:</h3>

Gas law : Boyle's law

New pressure: 66.24 atm

<h3>Explanation:</h3>

Concept tested: Gas laws (Boyle's law)

<u>We are given,</u>

  • Initial pressure, P₁ = 2.86 atm
  • Initial volume, V₁ = 8472 mL
  • New volume, V₂ IS 365.8 mL

We need to determine the new pressure, P₂

  • According to Boyle's law , the volume of a fixed mass of a gas and the pressure are inversely proportional at constant temperature.
  • That is, P\alpha \frac{1}{V}
  • This means , PV = k (constant)
  • Therefore; P₁V₁ = P₂V₂
  • Rearranging the formula, we can get the new pressure, P₂

P₂ = P₁V₁ ÷ V₂

   = (2.86 atm × 8472 mL) ÷ 365.8 mL

   = 66.24 atm

Therefore, the new pressure is 66.24 atm

1a) consider the mixed aldol condensation reaction of 1-methylcyclopentane-1-carbaldehyde (shown below) and 3,3-dimethyl-2-butan
zubka84 [21]
Aldehydes and ketones having α-hydrogen atoms, undergoes aldol condensation, in present of base (NaOH). 

The initial product formed during this reaction is β-hydroxy alcohol, which then undergoes dehydration to form α,β-unsaturated aldehyde or ketone.

In present case, 3,3-dimethyl-2-butanone  has 2α-hyrogen atom, while methylcyclopentane-1-carbaldehyde has 1α-hydrogen atom. So the major product formed during cross aldol condensation reaction of these reactants is:
 5-hydroxy-4,4-dimethly-1-(2-methylcyclopentyl)pent-1-en-3-one. 

The complete reaction product formed is shown below.

Option E, Real gas particles have more complex interactions than ideal gas particles.

In ideal gases, there is absolutely no interaction between any atoms. At all. Atoms simply don't bump into each other in ideal gases.

Obviously, you know that's unrealistic. In real gases, atoms collide into each other all the time.
