Answer:
crystal structure
Explanation:
A crystal structure is an ordered arrangement of atoms,ions or molecules in a regular repeating pattern,it is a form of solid state of matter and differs from liquid and gaseous states of matte in which the atoms or molecules are random or haphazard.
The combustion of methane, CH4, releases 890.4 kJ/mol. That is, when one mole of methane is burned, 890.4 kJ are given off to the surroundings. This means that the products have 890.4 kJ less than the reactants.
Answer:
Oxide sugar dissolved in water pond
because water + sugar= sugar melts but the oxide purifys the water.

we have,
wavelenght=c/f
where c= 3×10^8 m/s
f=6.3×10^12 s^-1
so wavelength=(3×10^8)/(6.3×10^12)
=0.476×10^-4 m
Answer:
6,500 gm of steam require= 3,510 kilo calories (approx)
Explanation:
Every 1 gram of water at 100° C absorb 540 calories
So,
Total water = 6.5 kg = 6,500 gram
So,
6,500 gm of steam require = 6,500 x 540
6,500 gm of steam require= 3,510 kilo calories (approx)
