Fist law of motion is piece of cake
<span>Things don’t move to get a shake </span>
<span>Second law of ,motion </span>
<span>Is all about the force </span>
<span>If something hits hard </span>
<span>Then the object takes that force </span>
<span>Third of motion is to give you satisfaction </span>
<span>For ever forth mate there is opposite reaction
Hope this helps. :)</span>
Use the concentration and molar mass.
1.00 L (2.00 mol KCl/1 L)(74.6 g/ 1 mol KCl)= 149.2 grams
So, you need about 149 grams of KCl dissolved in 1 liter of water to prepare a 2.00 M solution.
Answer:
74.9%.
Explanation:
Relative atomic mass data from a modern periodic table:
- Ca: 40.078;
- C: 12.011;
- O: 15.999.
What's the <em>theoretical</em> yield of this reaction?
In other words, what's the mass of the CO₂ that should come out of heating 40.1 grams of CaCO₃?
Molar mass of CaCO₃:
.
Number of moles of CaCO₃ available:
.
Look at the chemical equation. The coefficient in front of both CaCO₃ and CO₂ is one. Decomposing every mole of CaCO₃ should produce one mole of CO₂.
.
Molar mass of CO₂:
.
Mass of the 0.400655 moles of 
expected for the 40.1 grams of CaCO₃:
.
What's the <em>percentage</em> yield of this reaction?
.
Answer:
Red pandas live in the Eastern Himalayas in places like China, Nepal, and Bhutan . They spend most of their time in trees. Their semi-retractable claws help them move easily from branch to branch.
