How is the rate of appearance of h2o related to the rate of disappearance of o2?
erastovalidia [21]
If we consider a combustion reaction of Methane:

The balanced equation is:

CH4 + 2O2 ---> 2H2O + CO2

The rate of appearance of H2O is rH2O, rate of disappearance of O2 is -rO2

(rH2O)^2 = (-rO2)^2
rH2O = -rO2

Can anyone help me with the calculations for the Frequency, Wavelength, Energy Chart?
sergeinik [125]
Use the following equations to fill the chart.

E = hf
where
h = 6.63 x 10⁻³⁴ J/s, Planck's constant
f = frequency Hz
E = quanta of energy, J

c = fλ
where
c = 3 x 10⁸ m/s, the velocity of light
λ = wavelength, m

If energy is given in J/mmol, divide by Avogadro's number, N = 6.02 x 10²³, to convert it to J.

The completed table is shown below.

Another metal phosphate is cobalt phosphate. It will behave similar to calcium phosphate in an acid solution. What is the net io
ryzh [129]
We are given with
Cobalt phosphate - CoPO4

We are asked for the net ionic equation for the phosphate dissolving in H3O+

The net ionic equation is
CoPO4 (s) + H3O+ (aq) ----->  HPO42- (aq) + Co3+ (aq) + H2O *(l)

How many liters of oxygen gas can react with 84.0 grams of lithium metal at standard temperature and pressure? Show all of the w
ddd [48]
From the equation:
4mol Li react with 1 mol O2
Molar mass Li = 7g/mol
mol in 84g Li = 84/7 = 12 mol Li
From the equation - 12 mol Li will react with 3 mol O2

At STP 1 mol O2 has volume = 22.4L
<span> At STP 3 mol O2 has volume = 3*22.4 = 67.2L O2 gas will react. </span>
