Write out a “for every” statement that relates the amount of methane to the amount of oxygen gas (CH4 + 2O2 = CO2 + 2H2O)

Answers

Answer:

For every one molecule of methane, one molecule of oxygen is required to release one molecule of CO2 and 2 molecule of H2O

Explanation:

As we can in the balanced equation below -

CH4 + 2O2 = CO2 + 2H2O

One molecule of CH4 reacts with two molecule of oxygen to release one molecule of CO2 and 2 molecule of H2O.

Hence, it can be said

For every one molecule of methane, one molecule of oxygen is required to release one molecule of CO2 and 2 molecule of H2O

Which of these elements will successfully create a 1:1 bond with Carbon (C)
Carbon (C)
Silicon (Si)
Beryllium (Be)
Oxygen (0)

Answers

Answer:

Option B, Silicon

Explanation:

The valency of Carbon is 4 as it has four electrons in its outermost shell

The valency of Si is also four hence C

Hence Silicon can form 1:1 bond with the carbon

Valency of Beryllium is 2, hence it can not form 1:1 bond with carbon. Similarly the valency of oxygen and carbon are way different to form 1:1 bond

hence, only option B is correct

A student uses visible spectrophotometry to determine the concentration of CoCl2(aq) in a sample solution. First the student prepares a set of CoCl2(aq) solutions of known concentration. Then the student uses a spectrophotometer to determine the absorbance of each of the standard solutions at a wavelength of 510nm and constructs a standard curve. Finally, the student determines the absorbance of the sample of unknown concentration. The original solution used to make the solutions for the standard curve was prepared by dissolving 2.60g of CoCl2 (molar mass 130.g/mol) in enough water to make 100.mL of solution. What is the molar concentration of the solution

Answers

Answer:

0.200 M

Explanation:

Step 1: Given data

Mass of CoCl₂ (m): 2.60 gMolar mass of CoCl₂ (M): 130. g/molVolume of solution (V): 100. mL (0.100 L)

Step 2: Calculate the moles (n) of CoCl₂ (solute)

We will use the following expression.

n = m / M

n = 2.60 g / (130. g/mol) = 0.0200 mol

Step 3: Calculate the molar concentration of the solution

Molarity is equal to the moles of solute divided by the liters of solution.

M = n/V

M = 0.0200 mol/0.100 L = 0.200 M

B. CH3CO2H is an acid, and CH3CO2- is its conjugate base.

C. H3O+ is an acid, and CH3CO2- is its conjugate base.

D. CH3CO2H is a base, and H3O+ is its conjugate acid

Answers

In the buffer solution CH₃COOH (aq) ---> H₃O⁺(aq) + CH₃CO₂⁻(aq):

CH₃CO₂H is a base, and H₃O⁺ is its conjugate acid.

Option D is correct.

What is an acid?

An acid is described as a molecule or ion capable of either donating a proton, known as a Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid.

From the buffer solution above, H₃O⁺ is the conjugate acid because it donates a proton (H⁺) to a base CH₃CO₂H.

In conclusion, A conjugate acid, within the Brønsted–Lowry acid–base theory, is described as a chemical compound formed when an acid donates a proton (H⁺) to a base.

A certain element has a half-life of three years.

If you currently have a 10g sample of that element and you know that it has undergone five half-life decays, how many grams of the element were in the sample originally?

A
150g
B
160g
C
320g
D
50g

Answers

(C) 320 g

Explanation:

A = A02^(-t/hl)

where hl = half-life

A0 = original amount

A = present amount

t = elapsed time = 5 half-lives

10g = A02^(-5) = A0/32

A0 = 32×(10 g) = 320 g

if 300.0g of chlorine is reacted how much calcium hydroxide is needed to react with it

Answers

Answer:

334.7g of Calcium Hydroxide are needed

Explanation:

Based on the reaction:

2Ca(OH)2 + 2Cl2 → Ca(ClO)2 + CaCl2 + 2H2O

2 moles of chlorine react with 2 moles of calcium hydroxide.

To solve this question we must find the moles of chlorine in 300.0g. These moles = Moles of Ca(OH)2. With the moles of calcium hydroxide we can find its mass as follows:

Moles Cl₂ (Molar mass: 70.90g/mol)

300.0g Cl₂ * (1mol / 70.90g) = 4.2313 moles Cl₂ = Moles Ca(OH)₂

Mass Ca(OH)₂ (Molar mass: 74.093g/mol)

4.2313 moles Ca(OH)₂ * (74.093g / mol) =

334.7g of Calcium Hydroxide are needed

In 2Fe+3Cl2=2FeCl3, how much iron (Fe) is needed to produce 4 moles of FeCl3?

In 2Fe+3Cl2=2FeCl3, how much FeCl3 is produced when 5 moles of Fe react in excess chlorine?​

Answers

Answer:

4 mol Fe

5 mol FeCl₃

Explanation:

Step 1: Write the balanced equation

2 Fe + 3 Cl₂ ⇒ 2 FeCl₃

Step 2: Calculate how much iron (Fe) is needed to produce 4 moles of FeCl₃

According to the balanced equation, the molar ratio of Fe to FeCl₃ is 2:2.

4 mol FeCl₃ × 2 mol Fe/2 mol FeCl₃ = 4 mol Fe

Step 3: Calculate how much FeCl₃ is produced when 5 moles of Fe react in excess chlorine

According to the balanced equation, the molar ratio of Fe to FeCl₃ is 2:2.

5 mol Fe × 2 mol FeCl₃/2 mol Fe = 5 mol FeCl₃
