Answer:
Apples weigh more due to the larger mass, yet same quantity. With a 1050% increase over an average grape. Multiply 150g x 7g = 15000, bow multiply 7g x 100g = 700. Both equal
Explanation:
Your average apple weighs about 150g and 250g. The average grape weighs about 7g being small, and a large 11g. That's a 1050% increase.. Disclaimer I haven't measured massxweightxheight in awhile so might be completely wrong Mass is a measure of how much force it will take to chanfe the path
Answer: The energy of a Br–F bond is 110 kJ/mol
Explanation:
The balanced chemical reaction is,
The expression for enthalpy change is,
where,
n = number of moles
Now put all the given values in this expression, we get
Thus the energy, in kJ/mol, of a Br–F bond is 110
The electronegativity generally increases as you go from left to right across the periodic table. It decreases as you go down the periodic table. So the answer is nitrogen.
Molar mass Zinc chloride
ZnCl2 = 65.3 + 35.5 * 2 = 136.3 g/moles
1 mole ZnCl2 ------------- 136.3 g
x mole ZnCl2 ------------- 302.48 g
x = 302.48 / 136.3
x = 2.219 moles
1 mole --------------- 6.02x10²³ units
2.219 moles --------- y units
y = 2.219 * 6.02x10²³
y =
formula units
hope this helps!.
