Answer:
<h2>The answer is 70 kPa</h2>
Explanation:
In order to find the pressure if the volume were increased to 375 ml we use Boyle's law
That's
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final pressure
From the question
P1 = 105 kPa = 105 , 000 Pa
V1 = 250 mL
V2 = 375 mL
So we have
We have the final answer as
<h3>70 kPa</h3>

Explanation:
The boiling point of alcohols also increase as the length of hydrocarbon chain increases
Answer:
GG= Green Gg= Green Gg=yellow
Explanation:
Whenever there is a dominant allele it will ALWAYS show, the recessive alleles or lowercase letters show when they are paired together
The correct answer is D because the the rest will have different answers depending on the person you ask. D can be proven with facts by research
3.08*10^23 ions of Na+ and Cl- will be present in 30g of NaCl.
Weight of NaCl is equal to sum of weight of one mole of sodium and one mole of chloride.
Mathematically, it can be represented as -
1 mol (Na) + 1 mol (Cl)
= 23.0+ 35.5
= 58.5 g/mol
In 58.5 gram of NaCl, there is one mole of Na or 6.02*10^23 ions
In one gram of NaCl, there will be
=6.02*10^23/58.5 sodium ions
In 30 grams of NaCl, the number of sodium ions will be -
(6.02*10^23*30)/ 58.5
=3.08*10^23 ions
