Stronger intermolecular forces = higher boiling point
The stronger the intermolecular forces, the harder the molecules are to pull/break apart, which means a higher boiling point.

What is the chemical formula for Tetraphosphorous Pentachloride ?
Answer:
CH4
Explanation:
2534=(112)(25)x
help please!
Answer:
0.905
Explanation:
Answer:
x = 181/200
Explanation:
2534 = 112 . 25 . x (Multiply 112 and 25)
2534 = 2800x (Divide by 2800 from both sides)
x = 2534 / 2800 (Simplify)
x = 181/200 or 0.905

What 3 things drive the pressure of a gas up
Answer:
Density of the GasExplanation:
More molecules mean more hits against the container walls. Increasing the number of particles means you have increased the density of the gas. This third factor is part of the ideal gas law, which explains how these three factors -- temperature, volume and density -- interact with each other.

If you have 7.3g of solid calcium and it takes 62.3J of heat to melt it at 842°C. what would the heat of fusion for calcium?
Answer:
fttttggttfvvgfrr ccsfgt chg chu rdh fig ffhfr
Answer:
To solve this problem, you'll need the formula that relates heat energy to mass and heat of fusion:
q = m·ΔHf
where
q = heat energy
m = mass
ΔHf = heat of fusion
Explanation:
62.3J ÷ 7.3g = ΔHf
8.53 J/g = ΔHf
4.18 cal/g = ΔHf
What is unique about the metal mercury?
The sun’s mass is about 30 million times greater than the moon. Why does the gravitational pull between Earth and the moon affect Earth’s tides more than the gravitational pull between Earth and the sun? a The moon is denser than the sun. b The moon is closer to Earth than the sun. c The moon has phases, but the sun does not. d The moon orbits Earth, but the sun does not.
Answer:
The moon is closer to earth
Explanation:
Around each new moon and full moon, the sun, Earth, and moon arrange themselves more or less along a line in space. Then the pull on the tides increases, because the gravity of the sun reinforces the moon's gravity. ... Thus, at new moon or full moon, the tide's range is at its maximum.

A meteor is moving 468 km per minute traveling in a south-to-north direction passed near Earth in 2013. Does this statement describe the meteors speed or velocity?
Answer:
it's describes the velocity. since a direction was specifically given, that means it is displacement, and displacement is to velocity while distance is to speed
Answer:
since a direction was specifically given, that means it is displacement, and displacement is to velocity while distance is to speed
Explanation:
Martha ran 420 m, and Cole ran 60 m less than Martha. The distance Kate ran is right in the middle of Martha and Cole's distances. How far did Kate run?
Answer:
390 m
Explanation:
Martha ran 420 m
Cole ran 60 m less than Martha = 420 m - 60 m = 360 m
The distance Kate ran is right in the middle of Martha and Cole's distances
Kate distance = (420 + 360) / 2 = 780 / 2 = 390 m
In the above figure, what type of bond is formed?
metallic
ionic
covalent
nonpolar
Answer:
It is an covalent bond.
Explanation: The bond is covalent because all the dots are equaled to each other therefore creating a stable bond. When the bonded atoms have a lower total energy than that of widely separated atoms, a covalent bond forms. The electrons are not moved from one atom to the other in polar covalent bonds, such as that between hydrogen and oxygen atoms, as they are in an ionic bond.
why do some react so strongly against Charles Darwin's idea
Some people reacted so strongly because it went against their cultures and religious beliefs
How many do each element are present in the following formula? 3 Ca3 (PO4)2 + 4 CaO
I really need help plz help if you can!!!!!
3 Ca3 (PO4)2 + 4 CaO
So we can see that there are 3 Ca3 (Ca3, Ca3, Ca3), which means you multiply the subscript by the coefficient, meaning 9 Ca. Then we see (PO4)2, which means that there are two PO4 (PO4, PO4) so we multiply the subscript 2 by the subscript 4 on O to equal 8 O, and we multiply the subscript 2 by the subscript 1 on P (the 1 is not written) to equal 2 P.
So far we have 9 Ca, 8 O, and 2 P.
One last term, 4 CaO (means CaO, CaO, CaO, CaO) which translates to 4 Ca and 4 O.
Add them all together and you get (9+4=13) 13 Ca, (8+4=12) 12 O, and 2 P
Lithium hydroxide reacts with hydrobromic acid(HBr) to produce lithium bromide and water. If you
start with 3.00 moles of lithium hydroxide, how many moles of lithium bromide will be produced?
Answer:
3.00 moles of Lithium bromide will be produced
Explanation:
The reaction that takes place is:
LiOH + HBr → LiBr + H₂OBy looking at the reaction equation, we can see that the reaction of 1 mol of lithium hydroxide (LiOH) produces 1 mol of lithium bromide (LiBr). Thus, 3.00 moles of LiOH would conversely produce 3.00 moles of LiBr.

Why do engineers use metals in making
electrical wires
Answer:
Why is copper used for most electrical wiring? All metals have some amount of resistivity to electrical currents, which is why they require a power source to push the current through. The lower the level of resistivity, the more electrical conductivity a metal has

what is unique about the intertidal coastline ?
Answer: The intertidal or littoral zone maintains a balance between the land and the sea. It provides a home to specially adapted marine plants and animals.
Explanation: The intertidal zone is the area where the ocean meets the land between high and low tides. A tide pool within Monterey Bay National Marine Sanctuary. Intertidal zones exist anywhere the ocean meets the land, from steep, rocky ledges to long, sloping sandy beaches and mudflats that can extend for hundreds of meters.
How many atoms in 12 moles of oxygen
Answer:
7.23 x 10^24 atoms
Explanation:
Use Avogadro's number that states that there are 6.022 x 10^23 particles in one mole:
12 mol O x (6.022 x 10^23) atoms = 7.23 x 10^24 atoms

You have a 5-liter container with 1.30 x 1024 molecules of ammonia gas (NH3) at STP.
How many molecules of argon gas (Ar) are in an identical container at the same temperature and pressure?
1). 2.00 x 1023
molecules
2). 6.02 X 1024
molecules
3). 1.30 X 1024
molecules
4). 6.02 x 1023
molecules
Answer:
3). 1.30 × 10^(24) molecules
Explanation:
From avogadro's law which state that equal volume of all gases at the same temperature and pressure contain the same number of molecules.
We can relate it to this question as;
V₁/n₁ = V₂/n₂
Where;
V₁ is initial volume
n₁ is initial number of molecules
V₂ is final volume
n₂ is final number of molecules
Thus at STP, we have V₁ = V₂ and as such Plugging in the relevant values gives;
5/(1.30 x 10^(24)) = 5/n₂
n₂ = 1.30 x 10^(24) molecules
Answer:
1.30 X 1024 molecules
