Answers are:
1) trough - lowest point of the wave.
2) crest - highest point of wave.
3) amplitude - distance from rest position to the crest or thoughs.
4) wavelenght - distance from two consecutive crest or troughs.
5) rest position - the flat line running through middle of the wave.
Answer:
0.228 L is the volume that the gas occupies after it is driedand stored at STP.
Explanation:
Pressure of the wet gas = 
1 atm = 760 Torr
Pressure of water vapor = p = 0.0372 atm
Pressure of gas = 
Volume of wet gas = 
1 mL = 0.001 L
Temperature of the wet gas = 
Pressure of dry gas at STP = 
Temperature of the dry gas at STP ,
Volume of dry gas at STP = 
Using combined gas law:



0.228 L is the volume that the gas occupies after it is driedand stored at STP.
Answer:
- 1. Iodine is the limiting reactant
- 2.

Explanation:
<u>1. Balanced chemcial equation:</u>

<u>2. Theoretical mole ratio</u>
It is the ratio of the coefficients of the reactants in the balanced chemical equation:

<u>3. Actual ratio</u>
<u />
It is ratio of the moles available to reat:

<u>4. Comparison</u>

Then, there are more aluminum available than what is needed to react with the 9 moles of iodine, meaning that the aluminum is in excess and the iodine will react completely, being the latter the limiting reactant.
Conclusion: iodine is the limiting reactant.
<u>5. How much aluminum iodide will be produced?</u>
Use the theoretical mole ratio of aluminum iodide to iodide:

First one is balanced because all of the elements in reactant and product have equal number of atoms.
second one is not balanced therefore you need to add coefficient to balance it. so its CaCl2 + 2NaHCO3 = CO2 + CaCO3 + H2O + 2NaCl
both of them seem double replacement reaction
Hope it helps!

Answer:
The term Decimal is coined from the word Decimus. Decimus is a Latin word which means ‘tenth’.
The Decimal system is a system of numbering that is based on multiples of tens. It is flexible and easy to convert from one metric to another.
The preference of the term over the Metric System is because the word Metric is related more to the measurement of lengths if we looked at the origin of the word which is French.
