The answer will be (4) HI because the greater the difference of the bonds in electronegativity, the more polar a bond is.
Answer:
2,909 M
Explanation:
molair mass is of.ethylene is 26,04 g/mol
first you need to calculate how much mL 3 kg is. You can do this by using the density of ethylene: 1,1 g/mL.
3000 g x 1.1 = 3300 mL = 3,3 L
Next you need to calculate the amount of moles:
250 g / 26,04 g/mol = 9,60 mol
Now you can calculate the molarity:
9,6/3.3 = 2,909 M
I don't know the answer for the second question. I'm sorry.
Answer:
E = 147000 J
Explanation:
Given that,
The mass of meteor, m = 50 kg
The altitude of the meteor, h = 300 m
We need to find the potential energy of the meteor. The formula for the potential energy is given by :
Put all the values,
So, the required potential energy is equal to 147000 J.
For your second question its Diamonds,Rubys, Emeralds.
And for your first question its :Minerals are natural: These substances that form without any human help.
Minerals are solid: They don't droop or melt or evaporate.
Minerals are inorganic: They aren't carbon compounds like those found in living things.
Minerals are crystalline: They have a distinct recipe and arrangement of atoms.
