Answer:
the boiling point of HF is higher than H2 and F2
Explanation:
it is because inter molecular give is present in HF because of the Hydrogen bond present. Hydrogen bond is strong and will require much energy to break ,since no hydrogen bond is in the rest H2 and F2 has a low boiling point
Cause the heavier object makes you use a lot of force and the smaller object make you use less Force if that makes sense haha

Answer: 1031.33 kg of coke will produce 6400 kg of iron.
Explanation:
...(1)
...(2)
(1)+3 × (2)
...(3)
Mass of iron = 6400 kg = 6,400,000 g(1 kg = 1000 g)
Moles of iron =
According to reaction (3) , 4 moles of iron are produced from 3 moles of coke(C(s)) ,then 114,592.65 moles of iron will be produced from = moles of coke.
Mass of coke:
Hence, 1031.33 kg of coke will produce 6400 kg of iron.
Answer:
A
Explanation:
Cs has a higher rate of reaction because it's easier to remove an electron from it, thereby leading to faster reactivity
<u>Answer;</u>
-Work
If Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, <u>work </u> is being done.
<u>Explanation;</u>
- Work refers to the application of a given force over a distance. Thus, we can say work is the product of force and distance.
- Energy on the other hand is the ability of a body to change, its location, shape, or state of another body.
- According to the work-Energy principle, a change in the kinetic energy, which is the energy possessed by a body in motion, is equivalent to the net work done on the body.
