Which of the following is not a result when a change to an equilibrium system is applied? (2 points)Increasing the rate of the forward reaction will cause a shift to the left.

Increasing the rate of the reverse reaction will cause a shift to the left.

Decreasing the rate of the forward reaction will cause a shift to the left.

Decreasing the rate of the reverse reaction will cause a shift to the right.

Answer: Option (D) is the correct answer.

Explanation:

Valence shell is the shell present on the outermost core of an atom and electrons present in the valence shell are known as valence electrons.

If an atom has completely filled valence shell then it means the atom is not reactive in nature because it is already stable.

But when an atom has less than eight electrons in its valence shell then it means to attain stability the atom will readily attract electrons towards itself.

As the given element 1 has 8 electrons in its valence shell. Hence, it is not reactive in nature but element 2 has 6 valence electrons. So, in order to attain stability element 2 will readily attract 2 electrons from a donor atom.

Thus, we can conclude that element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

I got it right on the test

Answer:

Scientific advancements can detect some harmful events before they occur and it allows the society to plan for them, thereby reducing the risk of damage that occurs.

Explanation:

Scientific advancements reduce the natural disasters level in a region by evaluating the physical and chemical characteristics of the land.

Also, it develops new medical terminology and concepts that reduce the spread of hazardous diseases in society.

Satellites are used to predict the weather report and by using this report proper precautions can be taken at the time of floods and storms.

Construction of dams and canals highly reduced the risk of water overflowing in the lands.

Answer:  Scientists are able to detect and predict some hazardous events through scientific advancements. By detecting these events early, society can prepare for the events, thereby reducing the amount of damage to people and property caused by the hazardous event.

Answer:

27·92 %

Explanation:

Given chemical equation is

2C4H10 + 13O2 -----> 8CO2 + 10H2O

So according to the above balanced chemical equation for 2 moles of C4H10, 10 moles of water is produced

Molecular weight of C4H10 is 58 g

Molecular weight of water is 18 g

So for 116 g of C4H10, 180 g of water is produced and therefore for 1 g of C4H10 (180 ÷ 116) g of water is produced

∴ For 1 g of C4H10 1·552 g of water is produced

For 3000 g of C4H10, (3000 × 1·552) g of water is produced

∴ Number of grams of water produced for 3000 g of C4H10 is 4656 g

Percent yield =((experimental amount) ÷ (theoretical amount)) × 100

Here experimental amount is 4656 g

theoretical amount is 1300 g

∴ Percent yield = (1300 ÷ 4656) × 100 = 27·92 %

∴ Percent yield = 27·92 %
