Lesson 2.08
True
False
Answer:
true
Explanation:
i go to k12
Ocean water density varies more at the the poles throughout the year than at the equator. Therefore, the given statement is true.
What is density?Density is the mass of a specific material per unit volume. d = M/V, in which d is density, M is weight, and V is volume, is the formula for density. Grams per cubic centimeter are a typical unit of measurement for density. For instance, whereas Earth has a density of 5.51 grams, water has a density of 1 milligrams.
Particle density, which is typically represented as n, describes the number of particles per volume instead of the density of either a single particle. Ocean water density varies more at the the poles throughout the year than at the equator.
Therefore, the given statement is true.

Explanation:
What differentiates solid, liquid and gas phases from each other? As part of your response discuss how the energy of attraction between particles compares with their energy of motion (i.e. their kinetic energy, Ek), the distances between particles, their compressibility and their relative viscosities (i.e. resistance to flow).
Answer:
I hope this helps
Explanation:
Solid = low kinetic energy, close distance between particles, not compresssible, higher flow resistance
Liquid = lower kinetic energy than gases, closer distance between particles than gases, relatively compresssible, high flow resistance than gases
Gas = high kinetic energy, far distance between particles, compresssible, low flow resistance
Make a diagram showing how communication satellites could be used to relay
information from a broadcasting station in new york to a receiving station in
london.
Answer:
Explanation:
Satellite acts as a relay station for earth sources. A transmission station sends the information to the satellite, which in turn retransmits to the receiving stations. The original signal being transmitted from the earth station to the satellite is called uplink of 6 GHz The retransmitted signal from the satellite to the receiving station is called downlink of 4 GH frequency. The transponder is the transmitter-receiver combination in a transponder.

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

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

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.
Which is the correct formula for the ionic compound that results from these two atoms? PLS HELP!!!
Answer:
If I am not wrong is C x2y5
Explanation:
The concept of valency is used here to determine the formula of the ionic compounds. The number of valence electrons in 'X' is 2 and that of 'Y' is 5. The formula is X₃Y₂. The correct option is D.
What is an ionic compound?The crystalline solids which are formed by neatly packed ions of opposite charges are defined as the ionic compounds. These compounds are formed by the combination of metals with non-metals.
The combining capacity of an element is given by valency. The elements belonging to the same group have the same valency. It is related to how many electrons are in the outer shell.
Here the number of valence electrons in 'X' = 2
The number of valence electrons in 'Y' = 5
The element 'X' need 6 electrons to attain the octet and 'Y' needs 3 electrons to attain the octet.
X - 6
Y - 3
The formula of the ionic compound is X₃Y₂.

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.

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.

Adina is stranded on an island in the middle of the ocean. There is one stream on the island but the
water has lots of sand in it. Which technique should she use to remove the sand from the water?
Hint: give the technical term
Answer:Adina removed the sand, employing a shovel, however she be laborious and therefore the stream will carry off the silt and therefore the sand.
She does not have to be compelled to do something, however to attend.
You fill the metal pot with ocean water and boil the water, the water can turn out to be steam and can move upwards, there you would like to dam the steam victimization the long metal plate, so the steam condenses into pure water droplets.
The metal plate must be inclined so the droplets flow downwardly and at last falls into a clean pot.
Finally you get the water within the clean pot.

she can remove the sand , using a shovel , but that will be hard. eventually the stream will carry off the silt and the sand . thus she doesn't have to do anything , but to wait .
