Protons and neutrons have most of the mass but occupy very little of the volume of the atom.
Answer:
It will reach to its maximum volume.
Explanation:
Using Ideal gas equation for same mole of gas as
:-
Given ,
V₁ = 65.0 mL
V₂ = ?
P₁ = 745 torr
The conversion of P(torr) to P(atm) is shown below:
So,
Pressure = 745 / 760 atm = 0.9803 atm
P₁ = 0.9803 atm
P₂ = 0.066 atm
T₁ = 25 ºC
T₂ = -5 ºC
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25 + 273.15) K = 298.15 K
T₂ = (-5 + 273.15) K = 268.15 K
Using above equation as:
Solving for V₂ as:-
V₂ = 868 L
Given that:- V max = 835 L
<u>Thus, it will reach to its maximum volume.</u>
Answer: 127.5ml
Explanation:
To calculate the volume of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is KOH.
We are given:
Putting values in above equation, we get:
Thus 127.5 ml of 0.5M of HNO3 would be needed to react with 85ml of 0.75M of KOH
The answer is (2). To calculate the density, you need to divide the mass with volume. When doing division, the significant figures of result is the minimal of the numbers using before. So the answer is 2.
B trench
Explanation:
The feature found at most convergent margins is a trench.
A trench is a large depression that typifies most convergent margins.
- Oceanic trenches are natural topographic depressions found on the sea floor.
- These depressions forms where two plate boundaries converges.
- The denser one slides beneath the less dense one into the asthenosphere below.
- This is called a subduction zone.
- The margin between the two plates that are depression is a trench.
