Why do atoms of different elements vary in size?
Answer:
As you go down the periodic table, usually atoms get bigger because n gets bigger (there are electrons in higher shells). Effective nuclear charge does get bigger too going down the periodic table, but this effect is smaller than the change in shell.
Explanation:
what is the shape of graphite
Answer:
The molecular formula lists the symbol of each element within the compound followed by a number (usually in subscript). The letter and number indicate how many of each type of element are in the compound. If there is only one atom of a particular element, then no number is written after the element.
define adhesion and give an example?
Similar to Cohesion, adhesion is the attraction between molecules of different substances . Water uses adhesion when it's attraction to another substance is greater than the water's attraction to itself. if you have ever dropped a cup of water on a hardwood floor,you know that it spreads out instead of foaming beads.
Calculate the mass of 5.22 mol of He.
Answer:
The mass is 20, 89 grams of He.
Explanation:
We calculate the weight of 1 mol of He, from the atomic weight of each element obtained from the periodic table: Weight 1 mol He= 4, 0020602 g. 1 mol He-----4, 0020602 g. 5,22 mol He---x= (5,22 mol He x4, 0020602 g)/ 1 mol He= 20, 89 g

The mass of 5.22 mol of He will be 20.84 grams.
We have 5.22 mol of He.
We have to calculate its Mass.
Which element is represented by symbol He ?Helium is a chemical element with the symbol He and atomic number 2. It is a gas which is colorless, odorless, tasteless, non-toxic, inert and monatomic.
According to the question -
Number of moles of Helium = 5.22 mol
Now, I mole of Helium will have its mass equal to its Atomic weight. Therefore -
Mass of 1 mole of He = 4.002602 g
So, the mass of 5.2 mol of He will be = 5.2 x 4.002602 = 20.84 grams
Hence, the mass of 5.22 mol of He will be 20.84 grams.

is there an ultimate particle?
Answer:
We learn in school that matter is made of atoms and that atoms are made of smaller ingredients: protons, neutrons and electrons. Protons and neutrons are made of quarks, but electrons aren’t. As far as we can tell, quarks and electrons are fundamental particles, not built out of anything smaller.
Answer:
The recent discovery declared that the finding is very close to the ultimate particle called Higgs particle. This is believed to be the basic building block of the universe.

Which chemical equation is correctly balanced?
O Mg(NO3)2 + 2K2CO3 →→ MgCO3 + 2KNO3
O Mg(NO3)2 + K2CO3 → MgCO3 + 2 KNO3
2Mg(NO3)2 + K2CO3 - 2MgCO3 + KNO3
Mg(NO3)2 + K2CO3
MgCO3 + KNO3

It's the same paragragh/field trip except a different question
Field Trip to the Blacksmith Shop
Students at a middle school went to a local historical site on a field trip. While visiting the site they watched a demonstration in a blacksmith shop. Blacksmithing is the simplest form of forging and it is one of the methods by which metal was first worked. The metal to be forged is first heated to red heat in the fire of a forge, and then is beaten into shape on a metal anvil with sledges or hammers. Steel is used in the forging process. The material we call steel is a mixture of different metals. The element iron (Fe) makes up a large percentage of all steels, generally composing more than 75 percent of the mix by percent of total mass. Steel is made from iron, and in the process, some element percentages are reduced in the alloy composition (such as carbon and silicon), and other elements (such as chromium, nickel, and tungsten) are added, depending on the type of steel needed.
As the iron is worked on the anvil, the color changes from red to gray. Which of the following is happening to the molecules as the iron cools down?
The atoms move more slowly and closer together.
The atoms move more quickly and closer together.
The motion of the atoms stay mostly the same.
The motion of the atoms become very orderly.
Answer:
The atoms move more quickly and closer together.
Balance the equations of Al(OH)3+HNO3----Al(NO3)3+H2O
Answer:HNO3 + Al(OH)3 → Al(NO3)3 + H2O
Word equation: Nitic acid + Aluminum hydroxide → Aluminum nitrate + water
Type of Chemical Reaction: For this reaction we have a neutralization reaction.
Balancing Strategies: In this neutralization reaction we have HNO3 reacting with Al(OH)3.
Be sure to carefully count the O and H atoms on both sides of the equation, otherwise this will be a difficult equation to balance.
Hint 1
Start by balancing the N atoms.
Hint 2
Next balance the H atoms.

how does latitude affect the temperature in an area
Answer:
Latitudes are used to indicate a precise location of any feature on the earth's surface.
Temperature changes with latitudes .At higher latitudes, the Sun's rays are less direct. The farther an area is from the Equator, the lower its temperature. At the poles, the Sun's rays are least direct.Near the equator sun's rays are perpendicular resulting into very high temperatures. Generally, around the world, it gets warmer towards the equator and cooler towards the poles.

9. If 1,785 cal of heat is added to a 343 g sample of water (specific heat = 4.18J/g °C) at 1202,
what is the *final temperature of the water? *
(1 Point)
15.76°C
031'c
18.24°C
1.24°C
Answer:
17.21°C
Explanation:
Using the following formula;
Q = m × c × ∆T
Where;
Q = amount of heat in joules
m = mass of substance in grams
c = specific heat capacity of water (4.184 J/g°C)
∆T = final temperature - initial temperature
According to the information provided in this question,
Q = 1,785 cal
1 cal = 4.184 J
1785 cal = 7468.4J
m = 343grams
c = 4.18J/g °C
initial temperature = 12°C
Using Q = m × c × ∆T
7468.4 = 343 × 4.18 × (T - 12)
7468.4 = 1433.74(T - 12)
7468.4 = 1433.74T - 17204.88
7468.4 + 17204.88 = 1433.74T
24673.28 = 1433.74T
T = 24673.28 ÷ 1433.74
T = 17.21°C

Answer:
The higher the temperature the faster the air molecules move. / The lower the temperature the slower the air molecules move.
Explanation:
Both answers work. Higher temp = more energy = moving faster, and the opposite applies. Lower temp = less energy = moving slower.

You now have these half-reaction equations:
3e + HNO3 → NO
S→ H2SO4 + 6e
Which factor will you use for the top equation?
Which factor will you use for the bottom equation?
Explanation:
The two half equations are;
3e + HNO3 → NO
S→ H2SO4 + 6e
When balancing half equations, we have to make sure the number of electrons gained is equal to the number of electrons lost.
Which factor will you use for the top equation?
We multiply by 2 to make the number of electrons = 6e
