How many moles of oxygen are needed to burn 2.7 moles of methyl
QveST [7]

Answer:

3.38 moles of O2.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

4CH2OH + 5O2 → 4CO2 + 6H2O

From the balanced equation above,

4 moles of CH2OH required 5 moles of O2 for complete combustion.

Finally, we shall determine the number of mole of O2 needed to react with 2.7 moles of CH2OH. This can be obtained as follow:

From the balanced equation above,

4 moles of CH2OH required 5 moles of O2 for complete combustion.

Therefore, 2.7 moles of CH2OH will require = (2.7 × 5)/4 = 3.38 moles of O2 for complete combustion.

Thus, 3.38 moles of O2 is required.

Consider the following intermediate chemical equations.(IMAGE) -205.7 kJ -113.4 kJ -14.3 kJ 78.0 kJ
andrey2020 [161]

Answer:

Approximately -205.7\; \rm kJ.

Explanation:

This question can be solved using Hess's Law.

Start by considering: how can the first three reactions (with known \Delta H values) be combined to produce the reaction \rm CH_4\; (g) + 4\; \rm Cl_2\; (g) \to CCl_4\; (g) + 4\; HCl\; (g)?

Here's one possible combination:

  • Include the first reaction once, without inverting.
  • Invert the second reaction and include it once.
  • Include the third reaction after multiplying all its coefficients by two.

In other words, if (1), (2), and (3) denote the three reactions with know \Delta H values, respectively, then 1 \times (1) - 1 \times (2) + 2\times (3) will give the required reaction \rm CH_4\; (g) + 4\; \rm Cl_2\; (g) \to CCl_4\; (g) + 4\; HCl\; (g).

By Hess's Law, the \Delta H value of the reaction \rm CH_4\; (g) + 4\; \rm Cl_2\; (g) \to CCl_4\; (g) + 4\; HCl\; (g) will thus be:

\begin{aligned}&1 \times \Delta H_1 - 1\times \Delta H_2 + 2\times \Delta H_3\\ &= 1 \times 74.6\; \rm kJ - 1 \times 95.7\; \rm kJ +2 \times (-92.3\; \rm kJ) \\ &= -205.7\; \rm kJ\end{aligned}.

How many L of 3.0 M H2SO4 solution can be prepared by using 100.0 mL OF 18 M H2SO4?
max2010maxim [7]

Answer: A volume of 600 mL of 3.0 M H_{2}SO_{4} solution can be prepared by using 100.0 mL OF 18 M H_{2}SO_{4}.

Explanation:

Given: V_{1} = ?,        M_{1} = 3.0 M\\

V_{2} = 100.0 mL,       M_{2} = 18 M

Formula used to calculate the volume is as follows.

M_{1}V_{1} = M_{2}V_{2}

Substitute the values into above formula as follows.

M_{1}V_{1} = M_{2}V_{2}\\3.0 M \times V_{1} = 18 M \times 100.0 mL\\V_{1} = \frac{18 M \times 100.0 mL}{3.0M}\\= 600 mL

Thus, we can conclude that a volume of 600 mL of 3.0 M H_{2}SO_{4} solution can be prepared by using 100.0 mL OF 18 M H_{2}SO_{4}.

If you have A 6-g sugar cube (C12H22011) and dissolved in a cup of hot tea. The
Iteru [2.4K]

The percentage of sugar in the solution is 1%

To solve this question, we need to find the percentage of 6 out of 600.

Data given;

  • mass of sugar = 6g
  • mass of solution = 600g
<h3 /><h3>What is Percentage</h3>

This is the rate or proportion of a substance in the total value and multiplied by 100.

The percentage of sugar in the solution is calculated by

\frac{6}{600} * 100 = 1 %

The percentage of sugar in the solution is 1%
