They form molecules which can be in solution form if diluted in water, but some do form solutions on exposure to the atmosphere i.e they are deliquescent like pellets of sodium hydroxide
Answer:
The heat capacity of an object is an amount of energy divided by a temperature change, which has the dimension L2·M·T−2·Θ−1. Therefore, the SI unit J/K is equivalent to kilogram meter squared per second squared per kelvin (kg m2 s−2 K−1 ).
Explanation:
Because of the magnetic field, magnets can push or pull at a distance without touching an object
Moles of NH₃ : = 7.059
<h3>Further explanation</h3>
Given
120 g NH₃
Required
moles NH₃
Solution
The mole is the number of particles contained in a substance
<em>1 mol = 6.02.10²³
</em>
Moles can also be determined from the amount of substance mass and its molar mass
Mol = mass : Molar mass
So for 120 g (molar mass of NH₃ = 17 g/mol) :
= 120 g : 17 g/mol
= 7.059
