Answer:
Land and sea breeze
Explanation:
This uneven warming of the land during the day results in the phenomenon called land and sea breeze.
During the day, the land heats up faster than the nearby ocean. Ocean is made up of water with a high specific heat capacity. This derives pressurized air near the surface of the land to the ocean. At night, the ocean does not easily lose heat after the land has lost its own. Pressurized air moves from the ocean to the land. This causes the warming of the land during the night.What kind of information does the activity series of metals give us?
A. It lists the different charges metal ions can have.
B. It compares how reactive the metals are.
C. It tells us which metal compounds are soluble.
D. It tells us how good of a conductor a metal is.
An information does the activity series of metals give us that it compares how reactive the metals are. Therefore, option B is correct.
What do you mean by metals ?Metals are lustrous, opaque elements that conduct heat and electricity well. Most metals are malleable and ductile, and they are denser than the other elements.
The term "metal" is thought to have originated during the hippie movement, when "heavy" meant serious or deep. Metal music is defined by several elements, including heavily distorted guitar riffs and chords, powerful drumming, extra low-range bass notes, and aggressive or throaty vocals.
Thus, An information does the activity series of metals give us that it compares how reactive the metals are, option B is correct.

Answer:
Explain that as the water evaporates, water molecules go into the air. The water molecules that evaporate become a gas called water vapor. Only the water evaporates, leaving the sodium and chloride ions behind. The sodium and chloride ions attract each other and re- form salt crystals.

Why does the human eye see different colors?
Answer:
Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color. Newton observed that color is not inherent in objects. Rather, the surface of an object reflects some colors and absorbs all the others. We perceive only the reflected colors.

Convert 3.55 moles Nacl to formula units
Answer:
2.14 x 10²⁴ formula units
Explanation:
Given parameters:
Number of moles of NaCl = 3.55moles
Unknown:
Formula units of NaCl = ?
Solution:
A mole of substance contains the avogadro's number of particles. The number of particles could be protons, atoms, neutrons, formula units etc.
1 mole of substance = 6.02 x 10²³ formula units
3.55 mole of NaCl = 3.55 x 6.02 x 10²³
= 2.14 x 10²⁴ formula units

If I have 13 protons and 12 electrons what is my charge?
Answer:
The charge would be +1
Explanation:
Protons have a positive charge while electrons have a negative charge. Therefore, it's simple subtraction. In every case, subtract the number of electrons from the number of protons.
13 - 12 = 1
Therefore the charge is +1
Here's one more example:
If the element chromium (Cr) has 24 protons and 28 electrons, what is its charge? Remember that protons have a positive charge and electrons have a negative charge.
24 - 28 = -4
Charge = -4
It would be written as followed when associating charge with a specific element: [tex]Cr^{-4}[/tex]
If an element has a neutral charge, that means the number of protons and neutrons are the same. If you look at the periodic table of elements, all of the elements listed have a neutral charge. The 0 isn't showed in the corner because it isn't necessary.
Bonus Information:
This isn't related to your question, but I've come across confusions when it comes to particles. Remember that protons (+) and electrons (-) are the only particles that have a charge, therefore, as it says in it's name, neutrons are neutral or have no charge. Neutrons do not contribute to charge, but they do contribute to the mass of an atom. So the number of protons added to the number of neutrons equate to the mass of an atom. Electrons have mass, but it's so miniscule and insignificant that it doesn't even contribute to the overall mass of the atom, so don't count those.
Remember:
C = p - e
M = p + n
C = atomic charge, M = atomic mass, p =protons, n = neutrons, e = electrons

A. Atoms can make many different molecules, just like letters can make many different words.
B. Molecules must contain many different atoms, just like words must contain many different letters.
C. There are 26 different atoms that are used to form molecules, just like there are 26 different letters that are used to form words.
D. There are no rules for how letters combine to make words, just like there are no rules for how atoms combine to make molecules.
To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. The correct option is option A.
What is atom?
Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit. Atoms can make many different molecules, just like letters can make many different words.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.
Therefore, the correct option is option A that is Atoms can make many different molecules, just like letters can make many different words.

How many joules are released when 30.0 g of H2O(g) condenses at 100°C and cools to 10°C
Heat released : 79086 J
Further explanationCondenses :
1. phase change (gas - liquid) : heat of vaporization (ΔH vap for water = 2260 J/g)
2. cools from 100 - 10 : (Q=m.cΔT)
1. Q=m.ΔH vap
[tex]\tt Q=30\times 2260=67800~J[/tex]
2. Q=mc.ΔT(c water = 4.18 J/g C)
[tex]\tt Q=30\times 4.18\times (100-10)\\\\Q=11286~J[/tex]
Q tot = 67800 + 11286 = 79086 J

A 19.0 g piece of metal is heated to 99.0 °C and then placed in 150 mL of water at 21°C. The temperature of the water rose to 23°C. What is the specific heat of the metal?
Answer:
[tex]0.8696\ \text{J/g}^{\circ}\text{C}[/tex]
Explanation:
[tex]m_m[/tex] = Mass of metal = 19 g
[tex]c_m[/tex] = Specific heat of the metal
[tex]\Delta T_m[/tex] = Temperature difference of the metal = [tex]99-23=76^{\circ}\text{C}[/tex]
V = Volume of water = 150 mL = [tex]150\ \text{cm}^3[/tex]
[tex]\rho[/tex] = Density of water = [tex]1\ \text{g/cm}^3[/tex]
[tex]c_w[/tex] = Specific heat of the water = 4.186 J/g°C
[tex]\Delta T_w[/tex] = Temperature difference of the water = [tex]23-21=2^{\circ}\text{C}[/tex]
Mass of water
[tex]m_w= \rho V\\\Rightarrow m_w=1\times 150\\\Rightarrow m_w=150\ \text{g}[/tex]
Heat lost will be equal to the heat gained so we get
[tex]m_mc_m\Delta T_m=m_wc_w\Delta T_w\\\Rightarrow c_m=\dfrac{m_wc_w\Delta T_w}{m_m\Delta T_m}\\\Rightarrow c_m=\dfrac{150\times 4.186\times 2}{19\times 76}\\\Rightarrow c_m=0.8696\ \text{J/g}^{\circ}\text{C}[/tex]
The specific heat of the metal is [tex]0.8696\ \text{J/g}^{\circ}\text{C}[/tex].
