Answer:
56.82 Kg
Explanation:
Given data:
1 Kg = 2.20 lbs
Number of kilogram in 125 lbs = ?
Solution:
lbs is used for pound. lb is abbreviation of libra. It is Latin word meaning balance.
Both kilogram and pounds are units of mass. Pound is smaller unit than kilogram.
one Kg = 2.20 lbs
Number of kg in 125 lbs:
125 lbs × 1 Kg/2.20 lbs
125 lbs.Kg/2.20 lbs
56.82 Kg
<span>An even smaller concentration measurement is parts per billion (ppb). One ppb is one part in 1 billion. One drop of ink in one of the largest tanker trucks used to haul gasoline would be an ink concentration of 1 ppb. It is important to know the difference between ppm and ppb. I hope this helped :)</span>
It would be in the fourth shell.
Answer is Option-3:
<span>C</span>₆H₁₄ (Hexane)<span> and H</span>₂O are immiscible.
Explanation:
Hexane is a chain of six carbon atoms attached to each other in straight chain and hydrogen atoms. All the bonds in this compound are non-polar. Hexane molecules interact with each other through London Dispersion Forces.
While, Water molecules are polar in nature, due to electronegativity difference between Oxygen and Hydrogen atoms the Hydrogen atom is partially positive and Oxygen atom is partially negative. And water molecles interact with each other through hydrogen bonding.
Result:
As we know LIKE DISSOLVES LIKE, so both Hexane and water are different from each other, so when mixed together thay fail to develop interactions with each other, Hence immiscible in each other.
Answer:
21 Moles of Carbon is reacted
Explanation:
According to Balanced Chemical Equation, 2 moles of Hydrogen reacts with 3 moles of Carbon. Hence, for 14 moles of Hydrogen,
= (3 C × 14 H₂) ÷ 2 H₂
= 21 Moles of C
