The number of moles of ions that are produced by the dissociation of o.5 mol of Na2CO3 is 1.5 moles
Explanation
write the equation for dissociation of Na2CO3
that is Na2Co3 → 2Na^+(aq) + CO3^2- (aq)
by use of mole ratio of Na2CO3 to Na^+ and to CO3^2- which is 1:2:1 the moles of Na^+ = 0.5 x2 = 1mole
the moles of CO3^2- = 0.5 x1 = 0.5 moles
total moles = moles of CO^2- + moles of Na^+
that is 1 mole + 0.5 mole = 1..5 moles
Answer:
ΔH of CH4(g)+2O2(g)→CO2(g)+2H2O(l) is -899 KJ
Explanation:
step 1: write down thye reaction and rearrange them in a way that similar contents cancel out to produce the required reaction and add the enthalpy change of each.
CH4(g)+O2(g)→CH2O(g)+H2O(g) ΔH = -284 KJ
CH2O(g)+O2(g)→CO2(g)+H2O(g) ΔH = -527 KJ
2H2O(g)→2H2O(l) ΔH = 44 KJ x -2
the minus is because the last reaction has been reversed and multiplied by 2 so that the gaseous state H2O cancels with the others to leave liquid H2O in the required final reaction.
ΔHrxn = (-284)+(-527)+[44 x (-2)] = -899 KJ
Answer:
Compounds 1 and 2 are not the same
Explanation:
To solve this question we need to find the molecular formula of the compounds converting the mass of each atom to moles.
<em>Molecular formula is defined as the simplest whole number ratio of atoms present in a molecula:</em>
<em />
Compound 1:
<em>Moles Tin: </em>
5.63g Sn * (1mol / 118.7g) = 0.04743 moles
<em>Moles Cl:</em>
3.37g Cl * (1mol / 35.45g) = 0.09506 moles
Ratio Cl:Sn
0.09506 moles / 0.04743 moles = 2
Molecular formula SnCl₂
Compound 2:
<em>Moles Tin: </em>
2.5g Sn * (1mol / 118.7g) = 0.02106 moles
<em>Moles Cl:</em>
2.98g Cl * (1mol / 35.45g) = 0.08406 moles
Ratio Cl:Sn
0.08406 moles / 0.02106 moles = 4
Molecular formula SnCl₄
Compounds 1 and 2 are not the same because molecular formulas are different.
I can form two compounds if I combine calcium, hydrogen and oxygen in five minutes.
<h3>What is a compound?</h3>
A compound is formed by the combination of atoms. It is important to note that the same atoms can be combined in different ways to produce new compounds.
