Water is H2O, whereas Hydrogen Peroxide is H2O2 -> the extra oxygen atom changes the substance entirely.
Answer:
2.07 Kcal heat must be added to completely melt the platinum.
Explanation:
Given data:
Molar heat of fusion = 4.700 Kcal / mol
Mass of platinum = 85.5 g
Heat of fusion = ?
Solution:
Formula:
ΔH = n × molar heat of fusion
n = number of moles
Now we will calculate the number of moles:
Number of moles = mass / molar mass
Number of moles = 85.5 g /195.08 g/mol
Number of moles = 0.44 mole
ΔH = n × molar heat of fusion
ΔH = 0.44 mol × 4.700 Kcal / mol
ΔH = 2.07 Kcal

Answer:
No it does not space does not have oxygen and air is caused by oxygen
hey but this was a really interesting question to ask tho
Explanation:
Answer:
Answer would be 4/2
Explanation:
A is the best answer choice because it was between A and D but 2 is not the denominator so it couldnt be D
