Can you tell us what you mean and post the questions ?
Boyle Law says “the pressure of fixed amount of ideal gas which is at constant temperature is
inversely proportional to its volume".<span>
P = 1/V
<span>Where, P is pressure of the ideal gas and V is volume of the ideal gas.</span>
<span>For two situations, this law can be added as;
P</span>₁V₁ = P₂V₂<span>
</span><span>14 lb/in² x V₁ = 70 lb/in² x 500 mL</span><span>
</span><span>V₁ =
2500 mL</span><span>
Hence, the needed volume of atmospheric air = 2500
mL
<span>Here, we made two </span>assumptions. They are,
1. The
atmospheric air acts as ideal gas.
2.
Temperature is a constant.
<span>We didn't convert the units to SI units since
converting volume and pressure are products of two numbers, they will cut off. </span></span></span>
Answer:
ns²np⁵
Explanation:
The electronic configuration of elements of halogen group ends with 7 electrons in its outer most shell and they distributed as ns²np⁵.
Such as Cl (17 electron): 2,8,7 which is 1s²2s²2p⁶3s²3p⁵.
Answer:
hey, it's B
Explanation:
1 mol= 6.022×10²³ ions
0.2 mol= 0.2 × 6.022 × 10²³ ions
Answer:
<h3>The answer is 0.33 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula

where
m is the mass
f is the force
a is the acceleration
From the question
f = 25 N
m = 75 kg
We have

We have the final answer as
<h3>0.33 m/s²</h3>
Hope this helps you
