The more sunlight that is present, the better the oven will be able to produce electricity. This means that a solar oven will be more efficient on a sunny day than on a cloudy day. Also, depending on the time of day, if the solar panel is in shadow, the oven will greatly decrease in efficiency.
Answer:
Lithium oxide, Li₂O.
Explanation:
Hello!
In this case, according to the given amounts, it is possible to write down the chemical reaction as shown below:
Which means that the metallic oxide has the following formula: M₂O. Next, we can set up the following proportional factors according to the chemical reaction:
Thus, we perform the operations in order to obtain:
So we solve for x as shown below:
Whose molar mass corresponds to lithium, and therefore, the metallic oxide is lithium oxide, Li₂O.
Best regards!
I'm not sure, but hope this helps.
5 HIO3 + 4 FeI2 + 25 HCl = 4 FeCl3 + 13 ICl + 15H2O
HBr, HI, HCL, HNO3, H2SO4, HCLO4 are all acid based.
Answer:
pH = -log[H+]
Where [H+] = Hydrogen ion concentration
In this case,
[H+] = 1 × 10^(-2) = 10^(-2)
log{10^(-2)} = -2
-log{10^(-2)} = -(-2) = 2
pH = -log{10^(-2)} = 2
and hi.!!!
