All of these properties are known as physical properties.
Physical properties are such that they are measured without changing the composition of the of the matter which is under consideration. For example, the melting point of a substance may be tested without changing its composition. The change is also reversed easily. Physical properties are used to describe and observe matter. The other type of properties are chemical properties, which require the composition of a substance to be changed for them to be measured.
Answer:
The answer to your question is: Flask X
Explanation:
Data
Flask X Flask B
Molar mass 30 g 60 g
mass 1.2g 1.2 g
Pressure 1 atm 0.5 atm
Formula PV = nRT
In the formula, we can notice that the number of moles (n)
is directly proportional to the pressure.
Then, let's calculate the number of moles
flask X flask Y
30 g --------------- 1 mol 60 g -------------- 1 mol
1.2 g ---------------- x 1.2 g ------------- x
x = (1.2 x 1) / 30 x = (1.2 x 1) / 60
x = 0.04 mol x = 0.02 mol
From the results, we conclude that the flask with the gas of molar mass 30g is the flask with pressure of 1 atm, because the higher the number of moles, the higher the pressure.
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.
I’m pretty sure it’s single replacement
