Answer:
Meaning:from the valley town; the settlement in the valley. Sounding like the proper English surname it was derived from, Dalton is all about being smart and trendy with equal parts cool and nerdy. Dalton, which comes from “dael” or “valley,” and “tun,” or “settlement,” may have peaked in the 1990s, but that's okay.

Which of the following chemical reactions is most likely to have the largest equilibrium constant K?
A. CH3COOH(aq) + H2O(l) CH3COO- (aq) + H3O+(aq)
B. HCl(aq) + H2O(l) H3O+(aq) + Cl-(aq)
C. H3PO4(aq) + NH3(aq) H2PO4-(aq) + NH4+(aq)
D. CH3COO- (aq) + H2O(l) CH3COOH(aq) + OH-(aq)
Answer:
The answer to this question is HCl(aq) + H2O(l) = H3O+(aq) + Cl-(aq). HCl is considered a strong acid meaning it is 100% ionized in solution. The equilibrium constant is therefore very large.

Suppose you have 1000 lb of waste copper (II) oxide sitting in the basement of your factory. Do you see a problem with sending it to a landfill?
Answer:
Yes.
Explanation:
Yes, we have a problem with sending it to a landfill of copper oxide because it has harmful effect on the health of humans as well as more weight of the copper oxide. Copper oxide usually found in powder form which can easily be inhaled that causes death of the cell due to toxic effect on the mitochondria and lysosomes of the cell. It makes problem of health in carrying the copper oxide from the basement of the factory to the landfill region due to its power form so we can say that it can do problems to human health while carrying from one place to another.
A new organism is discovered. It is multicellular, heterotrophic, and does move on its own. To which two kingdoms could the organism belong?
Answer:It is a plant
Explanation:
A new organism is discovered. It is multicellular, heterotrophic, and does move on its own. The organism belong to Kingdom Animalia.
What do you mean by heterotrophs ?A heterotroph is an organism that obtains energy and nutrients from other plants or animals. The term is derived from the Greek words hetero, which means "other," and trophe, which means "nourishment."
Fungi are multicellular, heterotrophic eukaryotes with chitinous cell walls. Kingdom Plantae contains autotrophic organisms with cellulosic cell walls, whereas Kingdom Animalia contains heterotrophic organisms without cell walls.
Animalia is a kingdom of multicellular, heterotrophic organisms. This kingdom includes humans and other primates, as well as insects, fish, reptiles, and a variety of other animals.
Thus, The organism belongs to Kingdom Animalia.

What is the mass of sulfuric acid, h2so4, that is contained in 2.0L of a 5.85 M solution ?
A- 1147.44 grams
B- 0.12 grams
C- 11.7 grams
D- 98.07 grams
Answer:
A. 1147.44 grams
Explanation:
Multiply volume by molarity to get the moles of solution.
5.85 M = mol/2.0 L
mol = (5.85 M)(2.0 L)
mol = 11.7
There is 11.7 moles of H2SO4.
Convert to grams with molar mass.
11.7 mol H2SO4 x (98.076 g/1 mol) = 1147.49 g
Closest answer is A, 1147.44 g.

A solution of 6.2 M H2SO4 is diluted from 2.0 L to 3.0 L. What is the molarity of the resulting solution?
Answer:
Here's link to the answer:
bittuly/3a8Nt8
Explanation:
According to molar concentration, molarity of the resulting solution is 4.32 molar.
What is molar concentration?Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.
The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.
In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.Substitution in formula M₁V₁=M₂V₂ gives M₂=6.2×2/3=4.32 M.

When a 0.3546 g of vanadium metal is heated in air, it reacts with oxygen to achieve a
final mass of 0.6330 g. Calculate the empirical formula of this vanadium oxide
Answer:
V2O5 is the empirical formula of vanadium oxide
Explanation:
The molecular mass of Vanadium is 50.949 g/mol
Number of moles of vanadium = 0.3456 g/50.949 g/mol = 0.00696 moles
The molecular mass of Oxygen is 16.0 g/mol
Number of moles of Oxygen = (0.6330 – 0.354) g/16 g/mol = 0.0174 moles
Emperical formula
V (0.00696 moles/0.00696 moles) O (0.0174 moles /0.00696 moles)
V 1 O2.5
Multiply by two get a whole number
V2 O5

22 Determine the molar mass of an unknown gas that has a volume of 72.5 mL at a temperature of 68C, and a pressure of 0.980 atm and a mass of 0.207 g.
Answer:
81.5g/mol
Explanation:
Molar mass is the ratio between mass of a substance (In this case, 0.207g) and moles presents in this mass.
To solve this question we must find the moles of the gas in order to obtain the molar mass using:
PV = nRT
PV / RT = n
Where P is pressure = 0.980atm
V is volume in Liters = 0.0725L
R is gas constant = 0.082atmL/molK
T is absolute temperature = 68°C + 273.15 = 341.15K
0.980atm*0.0725L / 0.082atmL/molK*341.15K = n
2.54x10⁻³ moles = n
Thus, the molar mass of the gas is:
0.207g / 2.54x10⁻³ moles
81.5g/mol
