Answer:
Aside from the sun, the water cycle is driven by the transpiration in plants and respiration in humans. Humans and animals both release water vapor in the atmosphere.

Answer:
IHD = 0; no unsaturation in the formula
Explanation:
The IHD is also known as the degree of unsaturation formula. This formula is commonly used to get an idea of how many unsaturations a molecule has, and in this way, we can get an approach of the type of compound we are treating. For example, if this number is 1, it means that the compound has at least one unsaturation and it could be a double bond or just cyclical compound.
The IHD is calculated using the following expression:
IHD = (a + 1) - (b + x - c)/2 (1)
Where:
a: number of carbon
b: number of hydrogens
c: humber of nitrogens
x: number of halogens.
Now, we have the formula C₄H₉Cl, let's identify a, b, c and x:
a: 4 carbons; b = 9 hydrogens; C = none; X: 1 chlorine
Replacing in (1) we have:
IHD = (4+1) - (9+1)/2
IHD = 5 - (10/2)
<h2>
IHD = 0</h2>
So this number is 0, which means that the molecule does not have any kind of unsaturation (Non double bond, multi bond or cyclical).
Hope this helps
Answer:
3.47 × 10²³ C atoms
Solution:
Data Given:
Mass of Diamond = 48 mg = 0.048 g
M.Mass of Diamond = 12.01 g.mol⁻¹ (as it is purely Carbon)
Step 1: Calculate Moles of Diamond as,
Moles = Mass ÷ M.Mass
Putting values,
Moles = 0.048 g ÷ 12.01 g.mol⁻¹
Moles = 0.576 mol
Step 2: Calculate number of Carbon atoms,
As 1 mole of any substance contains 6.022 × 10²³ particles (Avogadro's Number) then the relation for Moles and Number of Carbon atoms can be written as,
Moles = Number of C Atoms ÷ 6.022 × 10²³ Atoms.mol⁻¹
Solving for Number of C atoms,
Number of C atoms = Moles × 6.022 × 10²³ Atoms.mol⁻¹
Putting value of moles,
Number of C atoms = 0.576 mol × 6.022 × 10²³ Atoms.mol⁻¹
Number of C atoms = 3.47 × 10²³ C atoms
