Answer:
This is most likely a multi-stepped reaction.
Explanation:
From the collision theory, we know that it is super improbable for 3 different molecules (2 NO and 1 O2) to all hit each other at the perfect speed in the perfect position to make the products. From this, we can pretty confidently say that this is most likely a multi-stepped reaction.
Hope this helps! :)
Gases take the shape of their container and have no definite volume because they can diffuse indefinitely. Answer C.
The oxidation state of Hydrogen in reactant side is 0 and that in product side is +1. Hence the reaction is oxidation.
Answer:
hydroxide and hydrogen
Explanation:
When a metal reacts with water, a metal hydroxide and hydrogen are formed. Sodium reacts vigorously with water.
Answer:
N = 603.32 × 10 ²⁰
Explanation:
Given data:
Wavelength of photon = 12.0 μm or 12 × 10 ⁻⁶ m
Energy = 1.0 KJ or 1000 j
Number of photons = ?
Solution:
Formula:
E = n . h . f
E = energy
N = number of photons
h = planck's constant
f = frequency
it is known that
f = c/λ
thus,
E = N . h . c / λ
Now we will put the values in formula.
1000 j = ( N. 6.63 × 10 ⁻³⁴ j.s × 3 × 10⁸ m/s ) / 12 × 10 ⁻⁶ m
N = 1000 j ×12 × 10 ⁻⁶ m / 6.63 × 10 ⁻³⁴ j.s × 3 × 10⁸ m/s
N = 12000 j × 10 ⁻⁶ m / 19.89 × 10 ⁻²⁶ j. m
N = 603.32 × 10 ²⁰
