You live near the ocean and your friend lives further inland. Based on this, what can you say is most likely different about the climate in your area from your friend's area in the winter?
Your friend has colder winters than you do.
Your friend has warmer winters than you do.
You have less precipitation than your friend does.
You get more sunshine in the winter.
Answer:
I'm thinking its "Your friend had colder winters than you do."
Explanation:
It is not "Your friend has warmer winters than you do." Or "You Have less precipitation than your friend does." I was doing this quiz before that had this question and its not those.
In the ocean side the the winter will be colder by the ocean breeze in the day time. The location of your friend farther from the ocean will have warmer winters than you.
What is sea breeze ?Any wind that flows from a big body of water onto or onto a landmass is called a sea breeze or an onshore breeze. Sea breezes form as a result of changes in air pressure brought on by the different heat capacities of water and dry land. Sea breezes are therefore more confined than prevailing winds.
A sea breeze is frequently seen along coasts after sunrise because land warms up far more quickly than water does when exposed to solar radiation. While dry ground also cools faster than water, a land breeze or offshore breeze has the opposite effect.
In winter seasons, along with the sea breeze make the climate more colder than that in locations farther from oceans. Hence, option b is correct.

Which statement is true about heat transfer? *
5 points
a. Heat can only transfer when touching another object.
b. Heat always travels up.
c. Heat transfers from cooler to warmer objects.
d. Heat transfers from hotter to cooler objects.
Answer: A
Explanation:
heat always passes from a warmer object to a cooler object until all objects are the same temperature. Conduction is how heat travels between objects that are touching. Conduction travels fastest through solids, but liquids and gases can also conduct heat.

What do you think is the primary reason why the Unionid mussel population declined whenever there is a dramatic increase in the Zebra mussel population?
Answer:
When the Zebra arrived they ate all the food so the Unionid mussels declined as they died from the lack of food. Causing the Zebra Zebra numbers to increase and Unionid numbers to decline.
0.14g of methanol is burnt and 3.04kJ of heat is released. Calculate the enthalpy of combustion of methanol.
Answer:
-694.8 kJ/mol ≅ -695 kJ
Explanation:
The enthalpy of combustion (ΔHc) is defined as the amount of heat that is released when 1 mol of the compound is burned. We have the mass of methanol (0.14 g) and we have to calculate the moles present in that mass. For that, we need the molecular weight of methanol, which is calculated from the molar mass of the chemical elements.
Methanol: CH₃OH
Mw(CH₃OH) = (12 g/mol x 1 C) + (1 g/mol x 3 H) + 16 g/mol O + 1 g/mol H = 32 g/mol
moles of CH₃OH = mass/Mw(CH₃OH) = 0.14 g/(32 g/mol) = 4.4 x 10⁻³ mol
As the heat is released, the change in enthalpy is a negative value: -3.04 kJ.
Finally, we divide the released heat (-3.04 kJ) into the number of moles of CH₃OH:
ΔHc= (-3.04 kJ)/(4.4 x 10⁻³ mol CH₃OH) = -694.8 kJ/mol ≅ -695 kJ
Las reacciones de adición son... 2 reactivos producen 2 productos nuevos 2 reactivos producen un solo producto 1 reactivos produce 2 productos El reactivo es una sustancia carbonada y O2
Answer:
Las reacciones de adición son... 2 reactivos producen un solo producto.
Explanation:
Las reacciones de síntesis o combinación ocurren cuando dos o más reactivos forman un solo producto; generalmente se libera calor, siendo reacción exotérmica. También se les conoce como reacciones de adición.
En otras palabras, las reacciones de adición son aquellas en las cuales todos los átomos de los reactivos van a formar parte de un único producto. Uno de los reactivos (al que se le suele llamar sustrato) debe contener un enlace doble, o uno triple. Las Reacciones de Adición se dan principalmente en Química Orgánica donde los dobles y triples enlaces son comunes.
La característica principal de estas reacciones es que durante el proceso, el doble o triple enlace se rompe formando nuevos enlaces.
Las reacciones de adición son... 2 reactivos producen un solo producto.

4. The radius of a hydrogen atom is 37 pm (1pm 10"m). How many hydrogen atoms lined up side to side would it take to make 1.00 inch? (Hint start with 1.00 inch)
Answer:
V = 4/3 * 3.1416 * (37x10-10)3
V = 2.12x10-25 cm3
d = m/V
d = 1.67x10-24 / 2.12x10-25 = 7.87 g/cm3
The difference in temperature, let's convert F to ºC:
ºC = -80-32/1.8 = -62.22 ºC
dT = -92.6 + 62.2 = -30.4 ºC
The number of hydrogen atoms lined up side to side to make 1.00 inch is equal to 3.43 × 10⁷ atoms when the radius of one H-atom is 37 pm.
What is the radius of a hydrogen atom?The atomic radius of a hydrogen atom is the distance between the center of the nucleus to the boundary of the electron that surrounds it.
Given, the radius of the hydrogen atom = 37pm
Then the diameter of the hydrogen atom = 37 + 37 = 74 pm
We know that 1 pm = 10⁻¹¹ m
Then the diameter of the one H - atom = 74 × 10⁻¹¹ m
The value of 1 m = 100 cm then the diameter of H-atom = 74 × 10⁻⁹ cm
As we know, the value of one inch = 2.52 cm
So, if 74 × 10⁻⁹ cm length takes H-atom = 1
Then, 2.52 cm would take hydrogen atoms = 2.52/ 74 × 10⁻⁹ = 3.43 × 10⁷
Therefore, 3.43 × 10⁷ hydrogen atoms lined up side to side to make 1.00 inch.

How much energy does a wave with a frequency of 7.0 x 1012 Hz have
Answer:
4.64 × 10⁻²¹ J/s
Explanation:
[Only if the wave travels at the speed of light]
Because a wave presumed to be at light speed is a photon, E = hf.
If frequency is not given, E = hc/λ
c is the speed of light in meters per second. c = 299, 792, 458 m/s.
λ is the wavelength which is dependent.
h or plancks constant = 6.62607004 × 10⁻³² m² kg / s.
E is in units of J / s or jules ( m² kg ) per second.
If the wave has a frequency of 7.0 x 10¹² Hz or 7 THz (Tera-Hertz).
