Carbon dioxide is released in________and taken in by plants in ______

alex41 [277]

Answer: A

Explanation:

Plants take in sunlight, water, carbon dioxide. The produce sugar (glucose) and other things. It could not be deforestation. It can't be evaporation, that is from the water cycle. It cant be C due to it talking about precipitation, which is also from the water cycle. Therefore, it can only be A

The mass defect for the formation of lithium-6 is 0.0343 g/mol. The binding energy for lithium-6 nuclei is ________ kJ/mol. Ente

Sholpan [36]

<u>Answer:</u> The binding energy for lithium-6 nuclei is 3.09 E+11

<u>Explanation:</u>

Binding energy is defined as the energy which holds the nucleus together. It is basically the product of mass defect and the square of the speed of light.

This energy is calculated by using Einstein's equation, which is:

$E=\Delta mc^2$

where,

E = Binding energy of the atom

$Delta m$ = Mass defect = 0.0343g/mol = $0.0343\times 10^{-3}kg/mol$ (Conversion factor: $1kg=10^3g$ )

c = speed of light = $3\times 10^8m/s$

Putting values in above equation, we get:

$E=0.0343\times 10^{-3}kg/mol\times (3\times 10^8m/s)^2$

$E=3.09\times 10^{14}J/mol=3.09\times 10^{11}kJ/mol$ (Conversion factor: $1kJ=10^3J$ )

Hence, the binding energy for lithium-6 nuclei is 3.09 E+11

Two substances with empirical formula HNO are hyponitrous acid (M = 62.04 g/mol) and nitroxyl (M = 31.02 g/mol).(d) When hyponit

astra-53 [7]

The cis and Trans-forms of hyponitrous acid are given below in the attached document.

Hyponitrous acid has the chemical formula H2N2O2 or HON=NOH. 62.028 g/mol is the molecular weight of it. Additionally, it can take either a trans or cis form. When dry, the trans-hyponitrous acid crystallizes into white, explosive particles. Additionally, it has a half-life of 16 days at 25oC at a pH 1-3 in aqueous solution and is a weak acid (pKa1=7.21, pKa2=11.54). It decomposes into nitrous oxide and water. It is incorrect to think of N2O as the anhydride of H2N2O2. However, even though cis acid is unknown, we can still get its sodium salts.
