Answer:
what you are putting on the concrete and how thick the concrete is.
Explanation:
If you want to but a house on a slab of concrete for a base, you will probably need a little more than you would for a sidewalk. If it is thicker, you will be able to hold more on it than you would if you spread it out thinly.
<u>Answer:</u> The mass of carbon monoxide required is 1.094 kg
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
Given mass of iron (III) oxide = 2.08 kg = 2080 g (Conversion factor: 1 kg = 1000 g)
Molar mass of iron (III) oxide = 159.69 g/mol
Plugging values in equation 1:
The given chemical equation follows:
By the stoichiometry of the reaction:
If 1 mole of iron (III) oxide reacts with 3 moles of CO
So, 13.02 moles of iron (III) oxide will react with = of CO
Molar mass of CO = 28.01 g/mol
Plugging values in equation 1:
Hence, the mass of carbon monoxide required is 1.094 kg
C because a series circuit only has one loop so it’s C
B. 0.9 <span>
</span>D.Light intensity has no effect on whether electrons are emitted or not.
and
A. X=1.9eV,Y=0.2eV
I already took the gizmo so I know these are right. The first one I got wrong b/c there was no graph and the last one I didn't understand. Basically for the last one you calculate the work function for the metals and find their difference.
Hope this helps.
