Answer:
A. 
B. 
Explanation:
Hello!
In this case, since the undergoing chemical reaction between nitrogen and hydrogen is:
Thus we proceed as follows:
A. Here, we first need to compute the moles of ammonia yielded by each reactant, in order to identify the limiting one:
Thus, since nitrogen yields the fewest moles of ammonia, we realize it is the limiting reactant, so the theoretical yield, in grams, of ammonia is:
B. Finally, since the actual yield of ammonia is 1.23, the percent yield turns out:
Best regards!
Answer & Explanation:
The molar mass of calcium chloride is 110.98 g/mol. We can use this information to solve this problem. We can set up our equation like this..
Multiply straight across on the top and straight across on the bottom.
Now divide.
So, there are 3.00 moles of calcium chloride contained in a 33 gram sample which is answer choice D.
Answer:
Contact force is a force that requires a contact between two bodies and is ubiquitous in nature
Explanation:
The force is distributed in two categories i.e
Contact Forces are the forces which is requires a contact between two bodies to occur.
The Types of contact forces are given below:
- Tension Force
- Normal Force
- Air Resistance Force
- Applied Force
- Spring Force
Some common daily examples of the contact force are
- Frictional force between the tyres of a moving vehicle and the road.
- Air flowing in opposite direction of a moving object.
- Pushing a table with hand and the friction between its base and floor.
- Stretching a rubber band with hands etc.
Also non-contact forces are Gravitational force, Electrical force and Magnetic force.
