1.1214 mL will a 0.205-mole sample of He occupy at 3.00 atm and 200 K.
<h3>What is an ideal gas equation?</h3>
The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
Using equation PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.
Given data:
P= 3.00 atm
V= ?
n=0.205 mole
R= 
T=200 K
Putting value in the given equation:
V= 1.1214 mL

Answer:
p-Nitro acetanilide. 2-Naphthol aniline dye.
<u>Answer:</u> The correct answer is Option D.
<u>Explanation:</u>
A non-polar covalent bond is defined as the bond which is formed between the atoms having no difference in electronegativity values. For Example: 
etc..
In this bond, the electrons are shared equally and 
value is equal to 0.
Hence, the correct answer is Option D.
Answer: The heat transfer by convection requires a solid-fluid interface, a temperature difference between the solid surface and the surrounding fluid and a motion of the fluid. The process of heat transfer by convection would occur when there is a movement of macro-particles of the fluid in space from a region of higher temperature to lower temperature.

Answer:
Power, 
No of bulbs = 78400000
Explanation:
We have,
Water flows over Niagara Falls at the average rate of 2,400,000 kg/s, it mean it is mass per unit time i.e. m/t.
It falls from a height of 50 m
The gravitational potential energy of falling water is given by :
P = mgh
Power is equal to the work done divided by time taken. So,
So,
Let there are n bulbs that could power 15 W LED. It can be calculated by dividing the power by 15. So,
It means that the number of bulbs are 78400000.
