The equation for the reaction between al(s) and pb+2(aq) is:

2al(s) + 3pb+2(aq) 2al+2(aq) + 3pb(s)

therefore, for each 2 moles of al(s) that are used, how many moles of pb(s) are formed?

from the 0.011 mole of al(s) consumed, calculate the number of moles of pb(s) that should have been formed: mole(s)

For each 2 moles of Al(s) that are used, 3 moles of Pb(s) are formed.

0.0165 moles of Pb(s) that should have been formed From the 0.011 mole of Al(s) consumed

Step-by-step explanation:

Given :

The equation for the reaction between Al(s) and Pb+2(aq) is:

2Al(s) + 3Pb+2(aq) 2Al+2(aq) + 3Pb(s)

To find: Therefore, for each 2 moles of Al(s) that are used, how many moles of Pb(s) are formed?

From the 0.011 mole of Al(s) consumed, calculate the number of moles of Pb(s) that should have been formed: mole(s)

Solution:

Now to calculate the how many moles of Pb(s) are formed for each 2 moles of Al(s) that are used

Consider the given equation.

So, we can see that for each 2 moles of Al(s) that are used, 3 moles of Pb(s) are formed.

Now , for 2 moles of Al(s) no. of moles of Pb(s) produced = 3

For 1 moles of Al(s) no. of moles of Pb(s) produced = $\frac{3}{2}$

For 0.011 mole of Al(s) consumed no. of moles of Pb(s) produced :

$\frac{3}{2} \times 0.011$

0.0165

Thus 0.0165 moles of Pb(s) that should have been formed From the 0.011 mole of Al(s) consumed .

Answer from: Skylynn11

3 moles of Pb(s) formed for each 2 moles of Al(s) consumed

0.0165 moles of Pb(s)should have been formed when 0.011 moles of Al(s) consumed

Step-by-step explanation:

We are given that the equation for the reaction between Al(s) and Pb+2(aq) is

given below:

$2Al(s)+3Pb+2(aq)\rightarrow 2Al+3(aq)+3Pb(s)$

2 moles of Al(s) consumed then number of Pb(s) formed=3 moles

1 mole of Al(s) consumed then number of Pb(s) formed= $\frac{3}{2}$ moles

0.011 moles of Al(s) consumed then number of moles of Pb(s) formed= $\frac{3}{2}\times 0.011=0.0165 moles$

3 moles of Pb(s) formed when 2 mole of Al(s) consumed

0.0165 moles of Pb(s) should have been formed when 0.011 moles of Al(s) consumed

Answer from: Quest

a 4/6 = 9/12 not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional. if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional

b 2/3 = 12/18

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
