The cycle repeats when the carbon stored in the atmosphere as carbon dioxide gas is taken in.
Rzqust [24]

Answer:

Order of the cycle:

Step -1>>>>Step -4 >>>> Step -3 >>>>> step -2.

Explanation:

<u>Step -1:</u>

Carbon dioxide is taken in by plants during photosynthesis.

<u>Step -4;</u>

The animal eats a plant and uses its carbohydrates for energy.

<u>Step - 3</u>

The animal releases the carbon dioxide back into the atmosphere during respiration.

<u>Step -2</u>

The cycle repeats when the carbon stored in the atmosphere as carbon dioxide gas is taken in.

Therefore, order of the cycle is Step -1>>>>Step -4 >>>> Step -3 >>>>> step -2.

Determine the electron-group arrangement, molecular shape, and ideal bond angle for the following molecule: PH3 Electron-group a
Alecsey [184]

Answer:

The molecular shape and ideal bond angle of the PH_{3} is trigonalbipyramidal and 109.5^{o} respectively.

Explanation:

The structure of  PH_{3}  is as follows.(in attachment)

From the structure,

Phosphor atom has one lone pair and three hydrogens are bonded by six electrons.

Therefore, total electrons invovled in the formation PH_{3}  is eight.

Hence, four electron groups which indicate the tetrahedral shape. But one pair is lone pair i.e, present on the phosphor atom.

Therefore, ideal geometry of the PH_{3}  molecule is <u>Trigonalbipyramidal.</u>

The ideal angle of trigonalbipyrmidal is 109.5^{o}.

All three bonds of P-H has 109.5^{o}.

Therefore, ideal bond angle is <u>109.5^{o}.</u>

2. You have 200g or a solution that contains 30g of hydrochloric acid (HCI),
alex41 [277]

Answer:

the percentage of your solution that made up of HCI acid is 15%

Explanation:

The computation of the percentage of your solution that made up of HCI acid is given below:

Given that

There is 200g or a solution that have 0 g of hydrochloric acid (HCI)

Based on the above information

The percentage is

= 30g ÷ 200g

= 15%

Hence, the percentage of your solution that made up of HCI acid is 15%

What is the value for (delta)G at 1000 K if (delta)H = -220 kJ/mol and (delta)S = -0.05 kJ/(molK)?
tankabanditka [31]
The system is isothermal, so we use the formula:
(delta)G = (delta)H - T (delta) S

Plugging in the given values:
(delta)G = -220 kJ/ mol - (1000K) (-0.05 kJ/mol K)
(delta)G = -170 kJ/mol

If we take a basis of 1 mol, the answer is
D. -170 kJ
