I'm going to take a guess here and say it is downhill because water runs down the hill eroding the ground which is why landslides can happen. I'm sorry if I'm wrong.
Since the equation for determining gravitational force is F=Mm/r^2, with the M standing for the mass of one object and m standing for the mass of the other object, and r being the distance between the two, then increasing the mass of one or both objects would increase the gravitational pull between the objects, while increasing the distance would lessen the gravitational pull.
Answer:
The value of ΔH when 21.9 grams of hydrogen gas reacts with an excess of oxygen gas is 2,647.71 kilo Joules.
Explanation:
Mass of hydrogen gas = 21.9 g
Moles of hydrogen gas =
When 1 mole of hydrogen gas reacts with an excess oxygen gas it gives 241.8 kJ of heat.
Then 10.95 moles hydrogen gas will give :
The value of ΔH when 21.9 grams of hydrogen gas reacts with an excess of oxygen gas is 2,647.71 kilo Joules.
Answer:
It is the most penetrating form of radiation - A
Explanation:
Answer:
<h2>775.75 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>775.75 moles</h3>
Hope this helps you
