Atoms according to the kinetic molecular theory, are described in a solid to simply be vibrating in fixed positions, and not moving rapidly in the container. Because of this, they take a fixed volume and have fixed shape.
Answer:
You didn't list the compounds it gave you so i cant cross check them to see it they are ionic bonds( which is the chemical bonding is formed between metal and nonmetal)
if you reply with the compounds it list I will be happy to check for you
False because I think it’s supposed to be photoheteroterotrophs
Answer:
Cl
Explanation:
Because the oxidation state reduces from+3 in ClO2- to +1 in ClO- and oxygen is being lost
Answer : The molar heat of fusion for substance X is, 775.6 cal/mol
Explanation :
First we have to calculate the moles of substance X.

Given:
Molar mass of substance X = 58.45 g/mole
Mass of substance X = 326.0 g
Now put all the given values in the above expression, we get:

Now we have to calculate the molar heat of fusion for substance X.

where,
Q = heat releases = 4325.8 cal
= molar heat of fusion for substance X = ?
n = moles = 5.577 mol
Now put all the given values in the above expression, we get:

Thus, the molar heat of fusion for substance X is, 775.6 cal/mol
