Calculate the mass of water produced when 2.15 g of butane reacts with excess oxygen in the equation 2C4H10(g)+13O2(g)→10H2O(g)+8CO2(g)

Answers

Answer 1

Answer: molar mass :

H₂O = 18.0 g/mol

C₄H₁₀ = 58.0 g/mol

2 C₄H₁₀(g)+ 13 O₂(g) →10 H₂O(g)+ 8 CO₂(g)

2 x ( 58.0) g -------------- 10 x ( 18.0 ) g
2.15 g -------------------- mass of water

mass of water = 2.15 x 10 x 18.0 / 2 x 58.0

mass of water = 387 / 116

mass of water = 3.336 g

hope this helps!

Consider the lewis structures for h2cch2, h2ccch2, and h2cccch2. what hybridization should be expected for the ch2 carbon and the middle ccc carbon, respectively?

Answers

Answer:

CH2 --> sp2 hybridization.

C-C-C --> sp hybridization.

Explanation:

The CH2 has two simple bonds to the H and one double bond to another C. This means that in the hybridization of this C are involved 3 orbitals: 1 s and 2 p, resulting in a sp2 hybridization.

The C-C-C central carbon has two double bonds, one to each C. This means that in the hybridization of this C are involved 2 orbitals: 1 s and 1 p, resulting in a sp hybridization.

Final answer:

The hybridization of the CH2 carbon is 'sp2' and the middle CCC carbon's hybridization in all mentioned molecules is 'sp'.

Explanation:

The carbon in CH2 in all the three molecules, H2CCH2, H2CCCH2, and H2CCCCH2 is always connected to two other atoms: a carbon and a hydrogen. Therefore, its hybridization is

sp2

. The middle carbon in ccc sequence is also linked to two other carbons only. Its hybridization is also

. To summarize, the CH2 carbon's hybridization in all the molecules is

sp2

and the middle CCC carbon's hybridization in all the molecules is

After creating a Beer's Law plot using standard solutions of Q, you determined the slope of Beer's Law to be 0.543 M-1. Your unknown solution of Q tested in Part B of the experiment had an absorbance of 0.144. Determine the concentration (in molarity) of the unknown solution Q from Part B. Do not use scientific notation or units in your response. If Carmen adds zeros after the decimal place, your answer will still be graded correctly.

Answers

Answer : The concentration (in molarity) of the unknown solution Q is, 0.265

Explanation :

Using Beer-Lambert's law :

$A=\epsilon * C* l$

where,

A = absorbance of solution

C = concentration of solution

l = path length

$\epsilon$ = molar absorptivity coefficient

From the Beer's Law plot between absorbance and concentration we concldue that the slope is equal to $\epsilon * l$ and path length is 1 cm.

As we are given that:

Slope = 0.543 M⁻¹

and,

Slope = $\epsilon * l$

$\epsilon * l=0.543M^(-1)$

$\epsilon * 1cm=0.543M^(-1)$

$\epsilon=0.543M^(-1)cm^(-1)$

Now we have to determine the concentration (in molarity) of the unknown solution Q.

Using Beer-Lambert's law :

$A=\epsilon * C* l$

$0.144=0.543M^(-1)cm^(-1)* C* 1cm$

$C=0.265M$

Therefore, the concentration (in molarity) of the unknown solution Q is, 0.265

Answers

All the following are examples of minerals, except timber.

The correct option is d, timber.

What are minerals?

Minerals are solid chemical compounds that have fixed or definite chemical compositions.

Some minerals are calcium, phosphorus, bauxite, iron etc.

Our body needs a very little amount of minerals for the boy's growth.

Timber is wood, which is not a mineral.

Thus, the correct option is d. timber.

Answer: D. Timber

Explanation:

In the last 100 years, the level of CO2 in the atmosphere has been significantly increased by man by: pesticides the burning of fossil fuels domestic heat incineration of waste products

Answers

The major contributor of CO2 in the atmosphere which has a human source is the burning of fossil fuels - this is the correct answer. This is especially serious concern since the industrialization, but also includes heating with coal in people's private homes.

Answer:

The correct answer is Option (2)- Burning up of fossil fuels

Explanation:

Fossils are the remnants of the ancient plants and animals that were buried millions of years ago. Those fuels that are made up of these fossilized matters are commonly termed as fossil fuel. For example, Petroleum, Coal and natural gas. These are the major source of energy.

These fossil fuels are limited in amount and are non-renewable sources of energy. These are exploited rapidly by human beings. This burning up of fossil fuels leads to the production of a large amount of Carbon dioxide (CO₂) gas that causes a significant impact on the atmosphere. The increase in the CO₂ content also leads to an increase in the global temperature of the earth.

In the last 100 years, the CO₂ level in the atmosphere has immensely increased.

Hence, the correct answer is option (2).

How does the equilibrium change to counter the removal of A in this reaction? A + B ⇌ AB

Answers

To counter the removal of A the equilibrium change by shifting toward the left

explanation

If the reaction is at equilibrium and we alter the condition a new equilibrium state is created

The removal of A led to the shift of equilibrium toward the left since it led to less molecules in reactant side which favor the backward reaction.( equilibrium shift to the left)

For Plato users :

The equilibrium SHIFTS LEFT. Simultaneously, there’s an increase in the REVERSE reaction.
