Answer:
c.
Explanation:
One of the main differences between an atom and an element is that an atom can be combined but an element cannot be combined. There are many combinations of atoms that make up different gases, liquids, and solids each with a unique makup. For example, water is made up of two hydrogen atoms and one oxygen atom (H20). Elements are made up of only the same type of atom. For example, the element Hydrogen can only contain hydrogen atoms, while the element Carbon can only contain carbon atoms.
Answer: 
Explanation:
Lattice energy : It is defined energy released when ions combine together in a gaseous phase to form a compound. it is energy possessed by the crystal lattice of a compound. Denoted by symbol 
.
, energy is absorbed while forming of the lattice
, energy is release while forming of the lattice
One mole of sodium ion when combines with one mole chloride ion release 786 kJ of energy.
energy is completely different from energy conservation. Energy conservation means saving energy through such things as insulating your home or using public transportation; generally it saves you money and helps the planet. The conservation of energy has nothing to do with saving energy: it's all about where energy
Answer:
The depth of the lake is 67.164 meters.
Explanation:
The combined gas equation is,
where,
= initial pressure of gas in bubble= ?
= final pressure of gas = 0.980 atm
= initial volume of gas = 
= final volume of gas = 8.00 × V
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
pressure of the gas in bubble initially is equal to the sum of final pressure and pressure exerted by water at depth h.
Where :
density of water = 
g = acceleration due gravity = 
h = 67.164 m
The depth of the lake is 67.164 meters.
