Take 5 * 2/1 = 10 mol NO needed
10 mol * 30 g/mol = 300g
Answer C
I think it’s solar but I’m sorry if that’s wrong :)
Answer:
50.0 °C
Explanation:
If all other variables are being held constant, you can find the temperature using Guy-Lussac's Law. The equation looks like this:
P₁ / T₁ = P₂ / T₂
In this equation, "P₁" and "T₁" represent the initial pressure and temperature. "P₂" and "T₂" represent the final pressure and temperature. You can find the missing temperature (T₂) by plugging the given values into the equation and simplifying.
P₁ = 405 pKa P₂ = 1013 pKa
T₁ = 20 °C T₂ = ? °C
P₁ / T₁ = P₂ / T₂ <----- Guy-Lussac's Law
405 pKa / 20 °C = 1013 pKa / T₂ <----- Insert values
20.25 = 1013 pKa / T₂ <----- Divide 20 from 405
20.25 x T₂ = 1013 pKa <----- Multiply both sides by T₂
T₂ = 50.0 °C <----- Divide both sides by 20.25
The answer for the question given is A. Heating with a flame.
One of the processes that cause a chemical change is heating. An example of this is cooking or baking, which causes a permanent chemical change in substances. Also, all of the other choices are examples of physical changes.
