D. All of the given statements are true in context of animal cloning.
Explanation:
Cloning is the method in which a similar genetic copy is produced.
Animal cloning is a complex process in which an organism of similar type is produced with same DNA to each other.
Mostly successfully cloned animals in live are cattle,sheep,goats...
Scientists have also cloned rats,mice,rabbits,horses...
This animal cloning is used for farming by the farmers which gives acceleration in their crop production.
Animal cloning have showed some adverse affects in sheep, and other mammal animals regarding issues in their organs like liver,heart,brain etc.
The success rate is very low like 10% in animal cloning due to many reasons such as surviving from birth to the cloned animals.
We need to first come up with a balanced equation:
→
We know that the molar ratio of hydrogen to oxygen to water now is 4:1:2.
Converting the amount of grams given to moles is as follows:
Hydrogen:
Oxygen:
We know now that the limiting reactant is oxygen. We can then know that the number of moles of water are produced are double the number of moles of oxygen used due to the ratio that we established at the beginning - 4:1:2.
So we now can use 6.25 moles of water as the amount produced.
Then we convert moles of water to grams:
Now we know that there are 112.59g of water produced when we start with 50g of hydrogen and 50g of water.
Over land or over cooler water they start to lose their power
Answer:
The percent yield of the reaction is 82.5%
Explanation:
Let's work with moles to get the percent yield.
Mass / Molar mass =
652.5 g / 158.03 g/m = 4.13 moles
If the theoretical yield of the reaction is 5 moles but we only made 4.13 moles, the percent yield will be:
(Produced yield / Theoretical yield) . 100 =
(4.13 / 5) . 100 = 82.5 %
Answer: Diatomic elements are a subgroup of diatomic molecules.
Explanation:
Every molecule that consists of two atoms is diatomic. Only if the two atoms are the same there is a diatomic element.
So O2 is a diatomic element (and thus a diatomic molecule)
HCl is a diatomic molecule, but not a diatomic element.
One example of diatomic is earth's atmosphere is a host to a few different diatomic molecules, including nitrogen (N2) and oxygen (O2, not to be confused with ozone, which is O3).
Hopes this helps you!
