Answer:
Answer is water, carbon dioxide, and energy, which yields glucose and oxygen, as in the well-known formula: 6 H2O + 6 CO2 + Energy = C6H12O6 + 6 O2. Hope it helps!
Answer:
121 g/mol
Explanation:
To find the molar mass, you first need to calculate the number of moles. For this, you need to use the Ideal Gas Law. The equation looks like this:
PV = nRT
In this equation,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = moles
-----> R = constant (0.0821 L*atm/mol*K)
-----> T = temperature (K)
Because density is comparing the mass per 1 liter, I am assuming that the system has a volume of 1 L. Before you can plug the given values into the equation, you first need to convert Celsius to Kelvin.
P = 1.00 atm R = 0.0821 L*atm/mol*K
V = 1.00 L T = 25.0. °C + 273.15 = 298.15 K
n = ? moles
PV = nRT
(1.00 atm)(1.00L) = n(0.0821 L*atm/mol*K)(298.15 K)
1.00 = n(0.0821 L*atm/mol*K)(298.15 K)
1.00 = (24.478115)n
0.0409 = n
Now, we need to find the molar mass using the number of moles per liter (calculated) and the density.
0.0409 moles ? grams 4.95 grams
---------------------- x ------------------ = ------------------
1 L 1 mole 1 L
? g/mol = 121 g/mol
**note: I am not 100% confident on this answer
No, it won't change the amount of reactants nor the products as a catalyst will only provide an alternative path where lower activation energy is needed for the process to take place.
hope this explains it
If it does, please give it a brainliest :)))
"O2 was produced at a faster rate.(C)"
The building of all the profiles is correct; The total number of electrons is correct, as well as the filling of the shells to their entirety. However, some charge calculations are off. First, we see that sodium loses an electron in its structure. Hence, it acquires a charge of +1, not -1. Also, Fluorine gains 2 electrons in its 2p subshell. Thus, its charge is -2, not -1 and this is wrong too. The only correct answer is C; aluminum lose 3 electrons from its p-shell and hence it has a charge of +3.
