Answer:
bond energy is high
Explanation:
The stronger a bond, the greater the energy required to break it.
Answer:
%age Yield = 42.9 %
Explanation:
Percentage Yield is defined as the actual yield divided by theoretical yield. It is given as,
%age Yield = Actual Yield / Theoretical Yield × 100 --- (1)
Also,
Actual Yield is the amount of desired product which is obtained after an experiment is completed. We can also call it the real yield which is obtained practically. While, theoretical yield is the yield which is calculated on paper. Hence, we can say that the actual yield is always less than theoretical yield due to many reasons including reaction conditions and researcher handling problems.
Thus we are given following data;
Theoretical Yield = 1.70 g
Actual Yield = 0.73 g
Putting these values in Eq. 1,
%age Yield = 0.73 g / 1.70 g × 100
%age Yield = 42.9 %
Its A It provides support for the body
The bones(Cartilage?) provide support for the body
The answer is D: A metal is added to an acid and hydrogen gas is formed, because that's a chemical reaction
