Answer:
Up to 80 - 120 days.
Explanation:
The flower will probably stay six to twelve days or so.
I'm not sure what's your hypothesis going to be, but I'll give you an example.
" <em>If</em> I __________, <em>then</em> the sunflower will grow up to 80 to 120 days."
In the blank space, you can write what you're going to do to your sunflower during the experiment.
Please correct me if I'm wrong.
No, there is a rule called HONC... they could also bond with o2, n, and c
Simple,
take a look at your periodic table, if you have it labeled look at the Halogen
Group, it includes: Flourine, Chlorine, Bromine, Iodine, and Astatine.
Now, a period on the periodic table is read from left to right, and goes
down the rows of the periodic table.
Go to Period 5, go all the way to the Halogens, what is there?
Iodine.
Thus, your answer.
Well first you need to convert all the substances into there other name. For example: you would change #1 to Mg+O=MgO. That would be known as a synthesis reaction.
We can use the ideal gas law equation to find the number of moles;
PV = nRT
where P - pressure
V - volume - 56.2 x 10⁻³ m³
n - number of moles
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature
standard temperature is 273 K
and standard pressure - 101 325 Pa
we can rearrange the equation to find the number of moles

substituting the values in the equation

n = 2.51 mol
molar mass of Ar - 40 g/mol
mass of Ar in the sample - 2.51 mol x 40 g/mol = 100.4 g
