Answer:
1.) Wind moving over a relatively flat water surface has less area to come in contact with the water, and this reduces energy transfer.
2.) Larger waves have extra spaces and areas to trap air, increasing the transfer of the wind's energy to the water.
Explanation:
I got it right on the test.
Wind moving over a relatively flat water surface has less area to come in contact with the water, and this reduces energy transfer and Larger waves have extra spaces and areas to trap air, increasing the transfer of the wind's energy to the water.
What is energy transfer?When energy of any body travels from the one body to the another body, then transfer of energy takes place.
In the oceans, winds transfer their energy to the ocean or to the sea by the interaction with the surface water. When on the surface of ocean or sea up and down movement of water occurs then the interaction of that water with wind takes place and transfer of energy from wind to sea happen. More roughness or more height of the water on the surface of sea observed ten more transfer of energy from wind to sea occur.
Hence, option (1) & (2) is correct i.e. wind moving over a relatively flat water surface reduces energy transfer and Larger waves increasing the transfer of the wind's energy to the water.

How many moles of NaNO, would you need to make 500 mL of a 2.5 M
solution of NaNO?
Answer:
1.25 moles NaNO
Explanation:
Molarity = moles/Volume (L)
moles = Molarity (M) x Volume (L)
M = 2.5 M
V = 500 mL = 0.5L
moles = M x V = 2.5 x 0.5 = 1.25 moles

Explanation:
The goal in this set up is to make sure all units cancel each other.
Since we need to go from grams to atoms, our final unit should be atoms.
Using method of elimination, let's see why other options are wrong.
A - Although 'g' is cancelled out, we are left with moles^2 / atoms
B - Although 'g' is cancelled out, we are left with moles^2 / atoms
C - Although 'mol' is cancelled out, we are left with g^2 / atoms

What will a balloon do to a cloth if its negatively charged
Answer:
This involves negatively charged particles (electrons) jumping to positively charged objects. When you rub the balloons against the fabric they become negatively charged. They take some of the electrons from the fabric and leave them positively charged.
Explanation:
Negative charges attract to positive charges. If a balloon is not rubbed with the wool cloth, it has an equal amount of negative to positive charges, so it will attract to a rubbed balloon. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.

Determine the percent yield for the reaction between 46.5 g of
ZnS and 13.3 g of oxygen if 18.l4 g of ZnO is recovered along with an unknown quantity of sulfur
dioxide.
please show work thank you
The percentage yield of the reaction has been 46.74%.
Percentage yield can be given as the ratio of the actual yield to the theoretical yield.
For the theoretical yield, the balanced equation will be:
[tex]\rm 2\;ZnS\;+\;3\;O_2\;\rightarrow\;2\;ZnO\;+\;2\;SO_2[/tex]
Thus, 2 moles of ZnS will give 2 moles of ZnO.
The moles of 46.5 g ZnS:
Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]
ZnS = [tex]\rm \dfrac{46.5}{97.474}[/tex]
ZnS = 0.477 mol
The moles of 13.3 grams Oxygen:
Oxygen = [tex]\rm \dfrac{13.3}{32}[/tex]
Oxygen = 0.415 mol.
The moles of 18.14 grams ZnO:
ZnO = [tex]\rm \dfrac{18.14}{81.38}[/tex]
ZnO = 0.222 mol
According to the balanced chemical equation,
2 moles ZnO = 2 moles ZnS
0.222 mol ZnO = 0.222 mol ZnS
2 moles ZnO = 3 moles Oxygen
0.222 mol ZnO = 0.334 mol of Oxygen
Since, both the reactants are in enough concentration,
The theoretical yield can be calculated with any of the reactants. The theoretical yield of ZnO from 46.5 grams of ZnS can be given as:
1 mole ZnS = 1 mol ZnO
0.477 mol of ZnS = 0.477 mol of ZnO.
The mass of 0.477 mol of ZnO:
Mass = moles [tex]\times[/tex] molecular weight
Mass of ZnO = 0.477 [tex]\times[/tex] 81.38
Mass of ZnO = 38.818 grams.
The theoretical yield of ZnO = 38.818 g.
The actual yield of ZnO = 18.14 g.
Percentage yield = [tex]\rm \dfrac{18.14}{38.81}\;\times\;100[/tex]
Percentage yield = 46.74 %
The percentage yield of the reaction has been 46.74%.

Nitric monoxide (NO) reacts with oxygen gas to form nitrogen dioxide (NO₂), a dark brown gas. If 5.895 mol of NO is mixed with 2.503 mol of O₂,
determine the limiting reagent.
calculate the number of grams of NO₂ produced.
and determine how many grams of excess reagent remain unreacted.
Answer:
Limiting reactant: O2
grams NO2 produced = 230.276 g NO2
grams of NO unused = 26.67 gNO
Explanation:
2NO + O2 --> 2NO2
Step 1: Determine the molar ratio NO:O2
molar ratio NO:O2 = 5.895: 2.503 = 2.35
stoichiometric molar ratio NO:O2 = 2:1
So, O2 is the limiting reactant.
Step2: Determine the grams of NO2:
?g NO2 = moles O2 x (2moles NO2/1 mol O2) x (MM NO2/ 1 mol NO2) = 2.503 x 2 x 46 = 230.276 g NO2
Step 3: Determine the amount of excess reagent unreacted
moles excess NO reacted = moles O2 x (2 moles NO/1 mol O2) = 2.503 x 2 = 5.006 moles NO reacted
moles NO unreacted = total moles NO - moles NO reacted = 5.895-5.006 =0.889 moles NO unreacted
mass NO unreacted = moles NO unreacted x MM NO = 0.889 x 30 =26.67 g NO unreacted
