Answer: mmmmmm asking for mrs.howard work I see lol good luck grace
Explanation:
Answer : The limiting reagent is 
Solution : Given,
Moles of methane = 2.8 moles
Moles of = 5 moles
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 mole of react with 1 mole of 
So, 5 moles of react with 
moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Hence, the limiting reagent is
This question includes four answer choices:
A. definite volume, highest molecular motion, highest kinetic energy
B. indefinite volume, least molecular motion, highest kinetic energy
C. definite volume, least molecular motion, lowest kinetic energy
D. definite volume, no molecular motion, lowest kinetic energy
Solids do not have the highest molecular motion (on the contrary they have the least molecular motion), so you can discard option A. Solids have a definite volume and the highest kinetic energy (given that they have the least molecular motion), so you discard option C. Molecules always have a vibrational motion, so you discard option D. Option C, have only characteristics that correctly describes a solid: definite volume, least molecular motion, lowest kinetic energy. Therefore, the answer is the option C.

Answer:
Use the x method, cross over each charge.
Explanation:
and 
the +1 and -1 cancel each other out, so it will be KBr
Answer:
Percentage of silver and sulphur in the compound is 87.08% and 12.91% respectively
Explanation:
Given:
Amount of silver = 29.0 g
Amount of sulphur= 4.30 g
To find:
Percent composition of the compound=?
Solution:
Total Molecule mass = amount of silver + amount of sulphur
Total Molecule mass = 29+4.3
Total Molecule mass = 33.3g
Percentage of silver:
=>
=>
=> 87.08%
Percentage of silver:
=>
=>
=> 12.91%
