Answer:
0.316 m
Explanation:
The wavelength of an electromagnetic radiation is given by the formula :
Speed of the electromagnetic radiation/ frequency of the electromagnetic radiation
Speed of electromagnetic radiation is given by 3*10^8 m/s
Frequency of the electromagnetic radiation is 9.50*10^8 Hz
Substituting the relevant values in the above formula:
3*10^8/9.50*10^8 = 3/9.5=0.316 m
So the required wavelength is 0.316 m
I think the answer would be d
Answer:
Only the oxygen needs to be balanced. There are equal numbers of hydrogen and carbon
Explanation:
Given expression:
C₂H₄ + O₂ → 2H₂O + 2CO₂
The law of conservation of mass suggests that chemical equations be balanced since atoms are neither created nor destroyed in the course of a chemical reaction. In retrospect, bonds are broken and chemical species are change to another form.
From the given equation, only oxygen is not balanced. This flouts the law of conservation.
On the reactant side, we have 2 oxygen on the product, we have 6.
You would calculate them by dividing them and then multiplying to get the final answer
