1: <u>FALSE</u> The physical properties of metals include <u>shininess</u>, malleability, ductility, and conductivity.
2: <u>FALSE</u> Neutrons are the particles in an atom that have a <u>neutral charge</u>. They aren't positive like protons. They aren't negative like electrons.
3: <u>TRUE</u> Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He is best remembered for formulating the Periodic Law and creating a farsighted version of the periodic table of elements. He is also known as the <u>"father of the periodic table"
</u>
Explanation:
Given mass of sugar = 1.202 g
Molar mass of the sugar , 
= 342.29 g/mol
a) Number of moles of sugar
Number of moles of sugar in 1.202 grams is 0.0035 moles
b)Moles of each element in
In a molecular formula of sugar there are 12 carbon, 22 hydrogen and 11 oxygen atoms
Moles of an element in molecule =
number of atoms of that element in a molecular formula × number of moles of compound
Moles of carbon = 12 × 0.0035 = 0.042 moles
Similarly
Moles of hydrogen = 22 × 0.0035 = 0.077 moles
Moles of oxygen =11 × 0.0035 = 0.0385 moles
c) Number of atoms of each type in
Number of carbon atoms =
Number of hydrogen =
Number of oxygen atoms = 
<span>The ammonia molecules have weaker inter molecular bonds then the hydrogen and nitrogen, this means that the ammonia condensed at a lower temperature so will be a liquid that will be separated from the reaction, while the nitrogen and hydrogen remain as gases so are easy are recycle back into the reacting chamber.</span>
Hey there! :
1) <span>
Solid Solutions </span>
Solid solutions are formed only by solutes and solid solvents. In
everyday life, the main examples of this type of solution are metallic alloys.
2) Liquid Solutions
Liquid solutions have liquid solvent, usually water, and solutes can be solid, liquid or gaseous.
3) Gaseous solutions
<span>This kind of solution is formed by the only mixture of gases. Air is an
example, as its approximate composition is 78% nitrogen gas, 21% oxygen gas and
1% of other gases.</span>
