Hello!
Data:
P (pressure) = 1 atm
V (volume) = 18.5 L
T (temperature) = 300 K
n (number of mols) = ? (in mol)
R (Gas constant) = 0.082 (atm*L/mol*K)
Apply the data to the Clapeyron equation (ideal gas equation), see:
Note:
If the feedback is to be considered, the closest r
esponse is 0.751 mol Nacl

Answer: the line Spectra of hydrogen lies between the ultra-violet, visible light and infra-red of the electro magnetic spectrum
Explanation:
Electromagnetic radiation spans an wide range of wavelengths and frequencies. This range is called the electromagnetic spectrum. The electromagnetic spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The 7 regions includes; radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
lower-energy radiation, such as radio waves, is expressed as frequency while microwaves, infrared, visible and UV light are usually expressed as wavelength and finally, higher-energy radiation such as X-rays and gamma rays, is expressed in terms of energy per photon.
Therefore, hydrogen lies between the ultra-violet, visible light and infra-red region of the electro magnetic spectrum.
The answer is <span>D. Nonvascular plants. These plants are usually very short and can't grow to be very tall. A good example is moss.

0.0018 grams is the mass of silver can 2 kJ of energy raise 15°C.
Explanation:
Data given:
heat supplied (q) = 2KJ or 2000 J
cp of silver= 0.24 j/gram °C (specific heat capacity is the amount of heat required to raise the temp of substance by 1 degree)
temperature = 15 degree centigrade
mass=?
using the equation for the heat capacity,
q= mcpT
m = 
Putting the values in the equation:
= 
= 0.0018 grams is the mass of silver in which 2 kJ of energy raise temperature by 15°C.
