An unknown substance dissolves in water but separates and floats in oil.
Answer:
Any polar substance
Explanation:
We know that non polar substances wont dissolve in water because they do not react properly with water molecules, any polar substance would dissolve in water and float in oil.
An unknown substance dissolves in water but separates and floats in oil is any polar substance.
What are polar substances?Polar substance are defined as those whose bonding with atoms like nitrogen, oxygen, or sulfur has resulted in discrete positive and negative charge areas.
It can also be defined as an electrical pole is typically created when a molecule has more positive charges on one end than negative charges on the other, forming an electrical pole.
Non polar substances are defined as a molecule that lacks charges at the ends because its electrons are evenly distributed and those that cancel one another out symmetrically.
It is can also be defined as in covalent compounds, there is no change in electronegativity.
Thus, an unknown substance dissolves in water but separates and floats in oil is any polar substance.

What is the molarity of a NaOH solution if 48.0 mL of a 0.220 M H2SO4 solution is required to neutralize a 25.0-mL sample of the NaOH solution?
Answer:
Molarity NaOH = 0.85M (2 sig figs)
Explanation:
48.0ml(0.220M H₂SO₄) + 25ml(Xmolar NaOH)H₂SO₄ + 2NaOH => Na₂SO₄ + 2H₂O
2(molarity x volume) H₂SO₄ = (molarity x volume) NaOH
2(0.220M x 48.0ml) = 25.0ml x Molarity NaOH
Molarity NaOH = 2(0.220M x 48.0ml)/25.0ml = 0.8448M ≅ 0.85M (2 sig figs)

Explanation:
Elements are pure substances that cannot be broken down into simpler substances by ordinary chemical means.
The element X has three naturally occurring isotopes. The masses (amu) and % abundance of the isotopes are given in the table below. The average atomic mass is ______amu. Give your answer two decimal places.
Answer:
In order to solve for this you would need to plug it into an equation. You would add them all up to eachother after multiplying them by their percentages.
So it would be (0.75*48.90)+(0.18*49.10)+(0.07*50.20). Plug it all into a calculator and you get 49.027amu. Then you would round to significant figures so 49.03amu should be your answer.

How many cobalt atoms are in 2 moles of cobalt?
That means that one mole of cobalt weighs 58.9332 grams (58.9332 g/mol). Based on that information, to convert 2 moles of cobalt to grams, we multiply 2 moles of cobalt by 58.9332.
12.04428152 x [tex]10^{23}[/tex] cobalt atoms are in 2 moles of cobalt.
What are moles?A mole is defined as 6.02214076 ×[tex]10^{23}[/tex]
of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
One mole of cobalt is equal to 6.02214076 ×[tex]10^{23}[/tex] atoms.
2 moles of cobalt is equal to 6.02214076 × [tex]10^{23}[/tex]atoms x 2
12.04428152 x [tex]10^{23}[/tex]

Beryllium (Be) has four electrons. Fluorine (F) has nine electrons. Which chemical formula shows the correct subscripts for the product of the reaction when beryllium and fluorine combine
Answer:
BeF2
Explanation:
The correct chemical formula for the product of the reaction when beryllium and fluorine combine is BF₂.
The valence electron of an atom determines how an atom goes into bonding.
Beryllium(Be) has 4 electron and has 2 valence electron. To fulfil the octet rule, it can easily give out this 2 electron during bonding.
Fluorine(F) has 9 electrons and 7 valency electrons. To fulfil the octet rule, it readily accepts a single electron.
The correct chemical formula for the product of the reaction when beryllium and fluorine combine is BF₂.
This means 1 atom of beryllium combines with 2 atoms of fluorine to form beryllium fluoride. The beryllium give its 2 valency electrons to the 2 atoms of fluorine. The 2 atoms of fluorine will now have a valency electron of 8 each. The octet rule has been fulfilled at this point.

When calculating relative atomic mass, which particle is the mass of a chlorine atom compared
to?
Given what we know, we can confirm that relative atomic mass is calculated by comparing the particles to the atomic mass of a carbon-12 atom.
Why compare to carbon-12?Carbon is a very common element. It was been studied greatly, telling us a great deal about the atom. It contains 6 protons and 6 neutrons.This makes it very stable and the standard for comparison.Therefore, given its abundant nature and the fact that it has been extensively studied, we can confirm that a carbon 12 atom has exactly 6 protons and 6 neutrons, making it very stable and the standard to which other atoms are compared.

If a 22.4 L volume of a sample of gas has a density of 0.900 grams/L at 1.00 atm and 0.00°C. Given
the following gases, which could it be?
A. Ne
B. CO
C. CO2
D. Kr
Answer:
Formula Weight of gas sample = 20.1 g/mole => Neon (Ne)
Explanation:
Use Ideal Gas Law formula to determine formula weight and compare to formula weights of answer choices.
PV = nRT = (mass/fwt)RT => fwt = (mass/Volume)RT = Density x R x T
Density = 0.900 grams/L
R = 0.08206 L·atm/mole·K
T = 0.00°C = 273Kfwt = (0.900g/L)(0.08206L·atm/mole·K )(273K)
= 20.1 g/mol => Neon (Ne)
