How many moles of calcium chloride are needed to react completely with 6.2 moles of silver nitrate

Chemistry
1 answer:
Harlamova29_29 [7]3 years ago
8 0

Answer:

3.1 mol

Step-by-step explanation:

The balanced equation is

CaCl₂ + 2AgNO₃ ⟶ Ca(NO₃)₂ + 2AgCl

You want to convert moles of AgNO₃ to moles of CaCl₂.

The molar ratio is 2 mol AgNO₃:1 mol CaCl₂

Moles of CaCl₂ = 6.2 mol AgNO₃ × (1 mol CaCl₂/2 mol AgNO₃)

Moles of CaCl₂ = 3.1 mol CaCl₂

The reaction will require 3.1 mol of CaCl₂.

If the weight of displaced liquid and the weight of an object are the same, the object will:
s344n2d4d5 [400]

Answer:

Float

Explanation:

If the weight of liquid displaced and the weight of an object are the same, the object will float in the liquid.

From Archimedes principle, when an object is immersed in fluid, a force called upthrust supports it and it equal to the weight of the liquid displaced.

When in a liquid, the weight of the liquid displaced is the same as that of the of the object, it will float and not sink.

What is the percent yield of LiCl if I produced 30.85g LiCl and my theoretical yield was calculated to be 35.40g LiCl?
marissa [1.9K]

Answer:

87.15%

Explanation:

To find percent yield, we can use this simple equation

\frac{Actual}{Theoretical} *100

Where "Actual" is the amount in grams actually collected from the reaction, and "Theoretical" is, well, the theoretical amount that should have been produced.

They give us these values, so to find the percent yield, just plug the numbers in.

\frac{30.85}{35.40} *100\\\\ =87.15

So, the percent yield is 87.15%

An easy trick to remember how to do this is just to divide the smaller number by the bigger number and move the decimal back two places. If you have a percent yield greater than 100%, something is wrong in the reaction.
