Answer:
The final volume is 1.1 L.
Explanation:
Given data:
Initial pressure of gas = 125 KPa
Final pressure of gas = 375 KPa
Initial volume = 3.3 L
Final volume = ?
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
125 Kpa × 3.3 L = 375 Kpa × V₂
V₂ = 412.5 KPa. L/375 Kpa
V₂ = 1.1 L
The volume of gas is reduced to the 1.1 L because of increasing pressure.
Answer:
16
Explanation:
Because the sum of all electron in that compound should be 41 and as it has one electron extra ,total no. of electrons are 42 .
So if we add 26 +16 we get 42
Hence it's correct answer
Answer:
1. Convert given mass of reactant to moles.
2. Convert moles of reactant to moles of product using the coefficients in the balanced equation.
3. Convert moles of product back to grams of product
Explanation:
In order to find out the mass of a given product in grams you would have to convert the grams into moles by multiplying 1 mole over the given mass of the reactant. Then, you would convert the moles of the reactant into moles of the product using mole ratio. And lastly, you would multiply by the mass of the product to calculate the mass back to grams.

Answer:
C.) Chromosomes
Explanation:
Nucleotides are made up of three parts: a deoxyribose sugar, a phosphate, and a nitrogen base.
Chromosomes are long, condensed strands of DNA.
A wave is a disturbance that carries energy from one place to another. Matter is NOT carried with the wave! A wave can move through matter (a medium). If it must have a medium, it is called a mechanical wave.
