Answer:
ocean, glaciers and ice caps,
ground water
Explanation:
High-speed winds transfer more energy to the ocean’s surface, creating bigger waves.
Question 10 options:
True
False
Answer:
I think that would be true. The faster the wind, the longer it blows, or the farther it can blow uninterrupted, the bigger the waves. Therefore, a wave's size depends on wind speed, wind duration, and the area over which the wind is blowing
Answer: True.
Explanation: Yes, waves get energy from the wind through friction, so you see those waves get bigger each time. The longer the winds blows, the more friction, and energy it's getting, meaning better, and deadly waves. The wind can sometimes cause tsunamis if the its blowing too hard.
How much heat is needed to raise the temperature of 20.0g of H2O by 10.6oC?
Answer:
ΔH = 8.87 x 10₅
Explanation:
q = mcΔT = 20g x 1.00 cal/g°C x 10.6°C = 212 cals x 4.184 j/cals = 8.87 x 10⁵ joules
An ideal gas occupies a volume V at an absolute temperature T. If the volume is halved and the pressure kept constant, what will happen to it's temperature?
a. It will halve to T/2.
b. It will increase to 3T.
c. It will increase to 2T.
d. It will remain the same.
Answer:
It will be halve of T
Explanation:
V1 = V
T1 = T
V2 = ½V
T2 = x
V1/T1 = V2/T2
V/T = ½V/x
Vx = ½VT
2Vx = VT
2x = T
x = ½T
Determine the empirical formula of the compound with the percent composition of 26.6% K, 35.3% Cr and 33.0% O. *
3 points
Answer:
KCrO₃
Explanation:
26.6% K, 35.3% Cr and 33.0% O
The steps in obtaining the empirical formulae from percentage composition is given as;
Step 1:
Divide the percentage composition by the atomic mass of the elements
K = 26.6 / 39.0983 = 0.6803
Cr = 35.3 / 51.9961 = 0.6789
O = 33.0 / 16 = 2.0625
Step 2:
Divide all though by the smallest number (0.6789)
K = 0.6803 / 0.6789 = 1.002
Cr = 0.6789 / 0.6789 = 1
O = 2.0625 / 0.6789 = 3.038
The Empirical formular is the ratio between the elements. This given as;
KCrO₃

1. The diagram above shows the repeating groups of atoms that make up two samples. Will the
properties of the two samples likely be the same or different? (Examples of properties are smell,
color, and the temperature at which a substance melts.)
Answer:
Will likely be the same
Explanation:
We can see in both pictures there is a black molecule and a red molecule. However, we also have a purple molecule in one image and a yellow in the other. It would LIKELY be the same because we have more of the same molecules then more different molecules. Hope this helps

Explanation:
moles of NH₃ = 11.9g/17.03 g/mol = 0.699 mole
moles of CN₂OH₄ = 1/2(0.699) mole =0.349 mole
Theoretical yield of CN₂OH₄ = (0.349 mole)(60 g/mole) = 20.963 grams
%Yield = Actual Yield/Theoretical Yield x 100%
= 18.5g/20.963g x 100% = 88.25%
Answer:
same process as last solution I did for you except the mole ratio isn't 1:1 here it is 2:1 so you diveide the moles of NH3 by 2 to get the urea moles
here I got 88.16% yield

Determine the percent yield for the reaction between 98.7 g of
Sb2S3 and excess oxygen gas if 72.4 g of Sb4O6 is recovered along with an unknown amount of sulfur dioxide.
The percent yield of the reaction would be 85.64%
Percent YieldFrom the balanced equation of the reaction:
[tex]9 O_2 + 2 Sb_2S_3 ---> 6 SO_2 + Sb_4O_6[/tex]
Mole ratio of Sb2S3 to Sb4O6 is 2:1
Mole of 98.7g Sb2S3 = 98.7/339.7
= 0.29 moles
Equivalent mole of Sb4O6 = 0.29/2
= 0.145 moles
Mass of 0.145 Sb4O6 = 0.145 x 583
= 84.535 g
Percent yield = yield/theoretical yield x 100
= 72.4/84.535 x 100
= 85.64%

If water is added to 145 mL of a 0.55 M KOH solution until the volume is 250 mL, what will the molarity of the diluted solution be?
Answer:
0.319 M
Explanation:
M1V1 = M2V2
M1 = 0.55M
V1=145 mL = 0.145 L
V2 = 250mL = 0.250L
M2 = M1V1/V2=0.55x0.145/0.250 = 0.319 M

In science, literature, and everything, equilibrium has the same meaning. The meaning simply put, is balance. If you wanted a sentence example, it could be something like:
'He sat down to try and recover his equilibrium.'
Or
'They can't maintain enough equilibrium to ride a bike.'
I hope you understand the meaning now?
write a detailed paragraph about how a volcano is formed. be sure to
include how density, convection currents, and plate tectonics all come
together to make a volcano.
Answer:
okay but give me brainliest
Explanation:
A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Volcanic flows are called lahars.

Identify 5 factors of weather
Answer:
"The five factors are: the latitude zone, the elevation of the land, topography (landforms), ocean currents and winds."
Explanation:
Answer:
The five factors that determine the weather of any land area are: the amount of solar energy received because of latitude; the area's elevation or proximity to mountains; nearness to large bodies of water and relative temperatures of land and water; the number of such storm systems as cyclones, hurricanes, and thunderstorms resulting from air-mass differences; and the distribution of air pressure over the land and nearest oceans, which produces varying wind and air mass patterns.
