If 2.5 grams of calcium bromide reacted with excess lithium oxide, how many grams of bromide product would be formed?

Chemistry
1 answer:
Ede4ka [16]3 years ago

Answer: 2.17 g of  bromide product would be formed

Explanation:

The reaction of calcium bromide with lithium oxide will be:

CaBr_2+Li_2O\rightarrow 2LiBr+CaO

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of calcium bromide}=\frac{2.5g}{199.9g/mol}=0.0125moles

As lithium oxide is in excess, calcium bromide is the limiting reagent.

According to stoichiometry :

1 mole of CaBr_2 produce = 2 moles of LiBr

Thus 0.0125 moles of CaBr_2 will require=\frac{2}{1}\times 0.0125=0.025moles  of NH_3

Mass of LiBr=moles\times {\text {Molar mass}}=0.025moles\times 86.8g/mol=2.17g

Thus 2.17 g of  bromide product would be formed

2. 2AgNO3 + CaCl2 → 2AgCl + Ca(NO3)2
Slav-nsk [51]

Answer:

84.4g of AgCl

Explanation:

Based on the reaction:

2AgNO₃ + CaCl₂ → 2AgCl + Ca(NO₃)₂

<em>2 moles of AgNO₃ and 1 mole of CaCl₂ priduce 2 moles of AgCl and 1 mole of Ca(NO₃)₂</em>

<em />

100g of each reactant are:

AgNO₃: 100g × (1mol / 169.87g) = 0.589 moles

CaCl₂: 100g × (1mol / 110.98g) = 0.901 moles

For a complete reaction of 0.901 moles of CaCl₂ are necessaries 0.901×2 = <em>1.802 moles of AgNO₃. </em>As there are just 0.589moles, <em>AgNO₃ is limitng reactant</em>

<em></em>

0.589 moles of AgNO₃ produce:

0.589 moles × ( 2 moles AgCl / 2 moles AgNO₃) =

<em>0.589 moles of AgC</em>l. In mass:

0.589 moles of AgCl × (143.32g / mol) =<em> 84.4g of AgCl</em>

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.

Explain difference in appearance between a pure substance and a mixture.
Nata [24]

A pure substance is a substance which cannot be separated physically or chemically. It is the same wherever found on earth. For example, pure gold is a pure substance. It will be the same whether it is found where you live or on another country. A mixture can be either homogeneous or heterogeneous. A homogeneous mixture is a mixture that looks the same throughout but is made of more than one element. An example of this would be salt and water mixture.  A heterogeneous mixture is a mixture in which you can easily identify the different parts which make it up. An example of this would be pizza. Both these mixtures can be broken into different parts either physically or chemically.

Hope it helps :)
