The answer is (d.) They contain only single bonds.
The hydrocarbons which only contain single bonds between the carbon atoms are referred as saturated hydrocarbons. These hydrocarbons have carbon atoms bonded by many hydrogen atoms making it saturated. These are also the simplest class of hydrocardons.
Answer:
The correct answer is 6.65 mg.
Explanation:
Based on the given information, the number of days given is 45.6 days. The original mass of sodium phosphate give is 175 mg. The half-life of phosphorus-32 is 14.3 days, therefore, the n or the number of half life will be,
n = 45.6/14.3 = 3.19
So, after 45.6 days, the mass of sodium phosphate sample left will be,
= Original mass × 1/2ⁿ
= 175 mg × 1/2 ^3.19
= 175 mg × 0.1096
= 34.3 mg of sodium phosphate left after 45.6 days
The molecular mass of Na₃³²PO₄ is 3 (23) + 32 + 4 (16) amu = 165 amu
Therefore, 165 grams of sodium phosphate comprise 32 grams of phosphorus.
So, 34.3 mg or 0.343 gram of sodium phosphate will contain,
= 0.343 × 32/165
= 6.65 mg of P³².
Mutualism is the ecological interaction between two organisms.
1. When a big fish eats a tinier fish
2. When a plant absorbs water
Answer:
There is no limitation at all because that is the basic theory of solution electrolysis
