consider the reaction between calcium oxide and carbon dioxide: cao ( s ) + co 2 ( g ) → caco 3 ( s ) a chemist allows 14.4 g of

MakcuM [25]

Answer:

CaO is the limiting reagent

Theoritical yield = 25.71 g

% Yield = 75.44%

Explanation:

1 mole = Molar mass of the substance

Molar Mass of CaO = 56 g/mol

Molar Mass of CaCO3 = 100 g/mol

Molar mass of CO2 = 44 g/mol

The balanced Equation is :

$CaO + CO_{2}\rightarrow CaCO_{3}$

1 mole of CaO reacts with = 1 mole of CO2

56 g of CaO reacts with = 44 g of CO2

1 g of CaO reacts with =

$\frac{44}{56}$

= 0.785 g of CO2

So,

14.4 g of CaO must react with = (14.4 x 0.785) g of CO2

= 11.31 g of CO2

Needed = 11.31 g

Available CO2 = 13.8 g (given)

So CO2 is in excess , hence CaO is the limiting reagent and product will produce from 14.4 g of CaO

$CaO + CO_{2}\rightarrow CaCO_{3}$

1 mole of CaO will produce 1 mole pf CaCO3

56 g of CaO produce = 100 g of CaCO3

1 g of CaO produce =

$\frac{100}{56}$

= 1.785 g of CaCO3

14.4 g of CaO will produce = (1.785 x 14.4) g of CaCO3

= 25.71 g of CaCO3

Theoritical Yield of CaCO3 = 25.71 g

Actual yield = 19.4 g

Percent Yield =

$\frac{Actual\ yield}{Theoritical\ yield}\times 100$

$\frac{19.4}{25.71}\times 100$

= 75.44 %

If you were to reach the location in 316 minutes, what is your average speed in

nirvana33 [79]

The average speed is zero if our frame of reference is the rotation of the Earth because the relative distance with respect to the earth is zero.

Average speed = 0.26 km/hr

total time = 316 minutes

distance = speed * time

= 8.3 * 5*1/30 = 8.3 *1/6

= 1.38 km

Average speed = total distance / total time

1.38 km / 5.27

= 0.26 km/hr

Distance is described to be the importance or length of displacement among positions. observe that the gap between two positions is not the same as the distance traveled between them. Distance traveled is the whole period of the path traveled among positions. Distance traveled isn't a vector.

There are three foremost styles of average: imply, median, and mode. each of these strategies works barely otherwise and frequently results in slightly distinct ordinary values. The suggest is the maximum usually used commonly. To get the mean cost, you add up all of the values and divide this general by means of the variety of values.

How should I write balanced net ionic equation for this reaction?

Maksim231197 [3]

Answer:

Explanation:

Assumptions

They would ionize completely, or you must assume that.
The volumes must be the same as well.
0.11M Cu(NO3)2 ===> 0.11MCu2+ + 0.22 NO3-

Note

The concentrations would merely add. All things change if the assumptions I've made are not true.
