Answer:
i guess none of these or 3.4% for 10%
Explanation:
I think the answer should be in the 30 to 40 number scale
Answer:
Yes, the formed product is calcium nitride, 
.
Explanation:
Hello,
In this case, the answer is yes, since nitrogen in gaseous state is able to react with calcium in solid state to form calcium nitride as shown below:
This is possible since calcium losses two electrons and nitrogen gains three electrons to remain positively and negatively charged respectively, forming the aforementioned ionic compound.
Best regards.
I = average intensity of sunlight reaching at Madison = 2000 Js⁻¹m⁻²
A = area on which the light strike = 4.80 cm² = 4.80 x 10⁻⁴ m²
energy received per second by the area is given as
E = IA
inserting the values
E = (2000) (4.80 x 10⁻⁴)
E = 0.96 J
λ = wavelength of the photons in the sunlight = 510 x 10⁻⁹ m
c = speed of light = 3 x 10⁸ m/s
h = plank's constant = 6.63 x 10⁻³⁴ J-s
n = number of photons received per second
energy received per second is also given as
E = n h c /λ
inserting the values
0.96 = n (6.63 x 10⁻³⁴) (3 x 10⁸) /(510 x 10⁻⁹)
n = 2.5 x 10¹⁸ per second
Refraction is the answer
