2AgNO3 + CaCl2 → 2AgCl + Ca(NO3)2
Harrizon [31]

It can be found that 337.5 g of AgCl formed from 100 g of silver nitrate and 258.4 g of AgCl from 100 g of CaCl₂.

<u>Explanation:</u>

2AgNO₃ + CaCl₂ → 2 AgCl + Ca(NO₃)₂

We have to find the amount of AgCl formed from 100 g of Silver nitrate by writing the expression.

100 g \text { of } A g N O_{3} \times \frac{2 \text { mol } A g N O_{3}}{169.87 g A g N O_{3}} \times \frac{2 \text { mol } A g C l}{1 \text { mol } A g N O_{3}} \times \frac{143.32 g A g C l}{1 \text { mol } A g C l}

= 337.5 g AgCl

In the same way, we can find the amount of silver chloride produced from 100 g of Calcium chloride.

It can be found as 258.4 g of AgCl produced from 100 g of Calcium chloride.

The reaction of 8.00 g of carbon with excess o2 yields 10.9 g of co2. what is the percent yield of this reaction?
DiKsa [7]
C+O2----> CO2
8.00g              10.9 g

8.00g C*1 molC/12.0g C= 0.667 mol C
10.2g CO2*1mol/(12.0+2*16.0)=0.232 mol CO2  actual yield
0.667 mol C gives 0.667 mol CO2 theoretical yield
% yield = (actual yield/theoretical yield)*100%=
=(0.232 mol CO2/0.667 mol CO2)*100%= 34.9%

A pumpkin rolls 3.78 km in 6.8 hours. What is its speed?
Zielflug [23.3K]

Answer:

The answer is

<h2>0.56 km/hr </h2>

Explanation:

The speed of an object given the distance and time can be found by using the formula

speed =  \frac{distance}{time}  \\

From the question

distance covered by pumpkin = 3.78 km

volume = 6.8 hours

The speed is

speed =  \frac{3.78}{6.80}  \\  = 0.5558823...

We have the final answer as

<h3>0.56 km/hr </h3>

Hope this helps you
