It will be Lithosphere that fills in that blank
Answer: similarities
- there are some cases where the element confer some of its own properties to the compound, so there are properties which are similar between the element and the compound, for example when an element is strongly charged with electrons, the element confer this property to the compound, and this similar between them.
- the other similarity is that both, the compound and element are formed of atoms, electrons and neutrons.
differences
The principal difference is that a element is conformed only by one element but a compound can be conformed for more than two elements.

Answer:
The balanced chemical equation is P₄ (s) + 5O₂ (g) → P₄O₁₀ (s)
Explanation:
In order to balance the chemical equation, you first need to see what's out of balance.
In this case our Oxygen is not balanced, so in order to make the two the same, we need to see what coefficient we need to add to the compounds to balance the problem.
So, adding a coefficient of 5 to the O₂ will result in an equal number of oxygen on both sides.
Answer:
135g Na2CO3
Explanation:
I'm going to assume you mean Molality which is mol solute/kg solvent
Molarity would be mol soute/ L solution
we know we have 155g of water which is .155 kg
essentially we have the equation:
mol/kg = 8.20
we substitute .155 in for kg and get:
mol/.155 = 8.20
Solving this gives mol = 1.271
now we must convert to grams using the molar mass
Molar mass Na2CO3 = 106G/mol
so to cancel moles we multiply:
1.271mol x 106g/mol
= 135g
That is, water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to a gas at constant temperature. Water's heat of vaporization is around 540 cal/g at 100 °C, water's boiling point.
