How many moles of ions are produced by the dissociation of 0.5 mol of na2co3?
tatiyna
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

Calculate ΔHrxn for the following reaction: CH4(g)+2O2(g)→CO2(g)+2H2O(l) Use the following reactions and given ΔH′s. CH4(g)+O2(g
harkovskaia [24]

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

Two unknown compounds are analyzed. Compound I contain 5.63 g of tin and 3.37 g of chlorine, while compound II contains 2.5 g of
oee [108]

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.

Hypothesis:
Kobotan [32]

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.

I can form two compounds if I combine calcium, hydrogen and oxygen in five minutes.
