The mole ratio is 2:19 or 1:9.5
The best way to solve this is to list all the elements out and count them.
Count subscripts first (if there is no subscript then there is 1 atom)
Then multiply by the coefficients
To balance write a coefficient and multiply
<span>3H2+N2--> NH3
H 2 x 3 = 6 H 3 (x2) = 6
N 2 N 1 (x2) = 2
Your answer is 2 . . . to balance this equation you will need a coefficient of 2</span>
Answer:
yes
Explanation:
since humans dig out the earth for resources o believe that fossils far every species that exists and is extinct will be found and will be pieced together
Answer:
chemical bonds
Explanation:
The atoms in chemical compounds are held together by attractive electrostatic interactions known as chemical bonds. Ionic compounds contain positively and negatively charged ions in a ratio that results in an overall charge of zero. The ions are held together in a regular spatial arrangement by electrostatic forces.
Explanation:
It is known that relation between wavelength and frequency is as follows.
where, 
= wavelength
c = speed of light = 
[/tex]\nu[/tex] = frequency
It is given that frequency is 
. Hence, putting this value into the above formula and calculate the wavelength as follows.
= 
or, = 
Thus, we can conclude that wavelength of given radiation is .
