Answer:
The frequency of this light is
.
Explanation:
Wavelength of the light = 
Speed of the light = c = 
Frequency of the light = 


The frequency of this light is
.
1.CO2 - carbon dioxide
<span>2.H2O - water </span>
<span>3.NaCl - salt </span>
<span>4.H2 - hydrogen</span>
This is going to take a while..
1. 2AgI + Na2S --> Ag2S + 2NaI
2. Na3PO4 + 3HCl --> 3NaCl + N3PO4
3. Ba3N2 + 6H2O --> 3Ba(OH)2 + 2NH3
4. TiCl4 + 2H2O --> TiO2 + 4HCl
5. 3CaCl2 + 2Na3PO4 --> Ca3(PO4)2 + 6NaCl
6. 2NaBr + Cl2 --> 2NaCl + Br2
7. Mg(OH)2 + 2HCl --> MgCl2 + 2H2O
Hopefully that helps.

Explanation:
Answer: a) 0.070 moles of oxygen were produced.
b) New pressure due to the oxygen gas is 2.4 atm
Explanation:
According to ideal gas equation:

P = pressure of gas = 2.7 atm
V = Volume of gas = 700 ml = 0.7 L
n = number of moles = ?
R = gas constant =
T =temperature = 329 K


Thus 0.070 moles of oxygen were produced.
When the 700 mL flask cools to a temperature of 293K.




The new pressure due to the oxygen gas is 2.4 atm
