The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons.
Answer:
Explanation:
Since the transferred heat is equal to the change in the internal energy, the heat is proportional to the mass of the substance and the temperature change. The transferred heat also depends on the substance so that, for example, the heat necessary to raise the temperature is less for alcohol than for water. Hope that helps!:)
Answer:
A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. The properties of the products are different from those of the reactants.
I hope this helps.
Answer:
has higher boiling point
Explanation:
has higher boiling point because in , 
has a very strong dipole and we know that whenever there is dipole-dipole interaction then boiling point increases. On the other hand in 
the NO group has not so strong dipole which weakens its boiling point
So the boiling point of is higher than the boiling point of
<span>Answer:
Equation:
N2(g) + 3H2(g) → 2NH3(g)
Check for limiting reactant
Molar mass N2 = 28g/mol
mol N2 in 31,500g = 31,500/28 = 1,125 mol N2
This will require 1,125*3 = 3,375 mol H2
Molar mass H2 = 2g/mol
Mol H2 in 5,220g = 5,220/2 = 2,610 mol H2
The H2 is limiting
From the equation:
3 mol H2 will produce 2mol NH3
2610 mol H2 will produce 2610*2/3 = 1,740 mol NH3
Molar mass NH3 = 17g/mol
Mass of 1740 mol NH3 = 1740*17 = 29,580g NH3 produced
Mass of NH3 produced = 29.6kg</span>
