Answer:
Determine the frequency of light with a wavelength of 2.775⋅10−7 cm. Answer in units of Hz?❤
B) 2
You would first balance GO4 by adding a coefficient of 3 in front of DnGO4 in the reactants. Then you’d balance the 3DnGO4 by adding a coefficient of 3 in front of Dn in the products. Finally you’d balance Eg by adding a coefficient of 2 in front of Eg to balance with the Eg2(GO4)3 in the products.
Relatively few hydrogen atoms
Answer : The number of grams of oxygen react must be, 170.4 grams.
Solution : Given,
Mass of
= 46.85 g
Molar mass of
= 44 g/mole
Molar mass of
= 32 g/mole
First we have to calculate the moles of
.

Now we have to calculate the moles of 
The balanced chemical reaction is,

From the balanced reaction we conclude that
As, 1 mole of
react with 5 mole of 
So, 1.065 moles of
react with
moles of 
Now we have to calculate the mass of 


Therefore, the number of grams of oxygen react must be, 170.4 grams.
Chemical Property is the answer
