Answer:
Decrease by the distance squared
Explanation:
<u><em>Gravitation formula:</em></u>
where
'F' is the force of attraction between the two bodies (Gravitational force),
'G' is the universal gravitational constant,
'M' is the mass of the first object,
'm' is the mass of the second object and
'r' is the distance between the centers of each object.
Hence, with the increase by distance between two objects , the gravitation decreases by the distance squared
Answer:As you have asked, I will not do your homework for you but will outline the reasoning…
Find out the atomic weight of all the species involved in the problem. Three decimals is more than sufficient.
Look at the periodic table of the elements and other resources (notes!) as necessary to determine the expected valence of the species
Once you know how many of these go with those, you are cruising…
You already know that 4Al+3O2→2Al2O3
So, you are in a great position to determine the number of moles of O2 , as you know you have 14.8 mol of Al and the ratio of combination is always 4 molecules.
Explanation:
They dont have definite shape, high density and volume.
But they can be mixed together very easily
hope you got your answer
The answer is actually Water Splitting! Hope this works:D
Answer:
= - 303.975 Joules
Explanation:
Given that:
The volume of the cylinder = 0.003 m^3
Now, to liters:
The volume = 0.003 *1000 L
= 3 L
For an open cylinder, we mean the atmospheric pressure is at standard condition.
Thus, the workdone = -PΔV
= - 1 atm (3 L)
= - 3 L atm
1 L atm to Joules
= 101.325 Joules
Therefore;
=- 3* 101.325 Joules
= - 303.975 Joules
