Answer:Chromatography technique that uses paper sheets or strips as the adsorbent being the stationary phase through which a solution is made to pass is called paper chromatography. It is an inexpensive method of separating dissolved chemical substances by their different migration rates across the sheets of paper.

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.
Answer : The mole ratios of Hydrazine to Hydrogen peroxide is 1 : 2 and
the mole ratios of Hydrazine to water is 1 : 4.
Explanation :
The balanced chemical equation is,
According to the given reaction,
1 mole of Hydrazine react with the 2 moles of Hydrogen peroxide.
Therefore, the mole ratios of Hydrazine to Hydrogen peroxide is 1 : 2
And in case of Hydrazine and water,
1 mole of Hydrazine gives 4 moles of water.
Therefore, the mole ratios of Hydrazine to water is 1 : 4
Tell your teacher. They'll know what to do and it's best to report it to them.
Answer:
d. Temperature and number of molecules of gas
Step-by-step explanation:
Boyle's Law states, "The volume of a fixed mass of a gas is inversely proportional to the pressure if the temperature remains constant."
Let's examine the words.
"… volume…is inversely proportional to the pressure …" This means that volume and pressure are the <em>variables</em>.
"… fixed mass of a gas …" means that the number of molecules is constant.
"… temperature remains constant" speaks for itself.
a, c, and e are <em>wrong</em>, because pressure is a variable.
b is <em>wrong</em>, because volume is a variable.
