What is the name for CuSO3? carbon (II) sulfate copper (II) sulfite carbon sulfte none of these copper (I) sulfate Previous
The inorganic chemical with the formula CuSO3 or CuO3S is copper(II) sulfite.
The inorganic compound copper(II) sulfate, also referred to as copper sulphate, has the formula CuSO4. CuSO4-nH2O hydrates are created, where n can be any value between 1 and 7. When copper loses the electrons in its outermost shell, a chemical known as copper carbonate (Cu2CO3(OH)2) is produced. Copper carbonate, sometimes referred to as copper (II) carbonate, carbonic acid, and copper monocarbonate, transforms into copper salts very fast. The response is polyatomic ionic, or c. The copper +2 cation (Cu2+ C u 2+) and the sulfate anion (SO24 S O 4 2 ) combine to form the ionic compound CuSO4 C u S O 4. Because the anion is made up of many atoms, the compound is.

what volume of a 6.0 m solution of hcl should i dilute to create 2.0 liters of a 0.75 m hcl solution?
About 0.25 liters of 6.0 m solutions of HCl should be added to create 2.0 liters of a 0.75 m HCl solution.
Lowering a solute's concentration in a solution is the process of dilution. It entails adding significantly additional water or solvent to the solution. When more solvent is added to a solution without extra solute, the solution gets diluted.
The dilution formula is M₁V₁=M₂V₂. Here, M₁ is the initial molarity, M₂ is the final molarity, V₁ is the initial volume, and V₂ is the final volume.
Given, M₁ is 6.0 M, M₂ is 0.75 M, and V₂ is 2.0 L. We have to find V₁.
[tex]\begin{aligned}V_1&=\frac{M_2V_2}{M_1}\\&=\frac{0.75\times2}{6}\\&=\mathrm{0.25\; L}\end{aligned}[/tex]

in the laboratory, a quantity of i2 was reacted with excess h2 to give 0.530 moles of hi. it is also known that the percent yield of this reaction was 72.0%. how many moles of i2 reacted? (hint: write a balanced equation.)
Knowing that the percent yield of this reaction was 72.0%, then 0.3681 moles I₂ was reacted with excess H₂.
Percent yield is defined as the ratio of the actual yield to the theoretical yield multiplied by 100.
Percent yield = (actual yield / theoretical yield) x 100
If a quantity of I₂ was reacted with excess H₂ to give 0.530 moles of HI, and the percent yield of this reaction was 72.0%, then the theoretical yield of the reaction should be 0.7361 moles of HI.
Percent yield = (actual yield / theoretical yield) x 100
72 = (0.530 / theoretical yield) x 100
theoretical yield = 0.7361 moles
Then, write a balanced equation for the reaction of I₂ and H₂ to produce HI.
I₂ + H₂ ⇒ 2 HI
From the balanced equation, 1 mole of I₂ requires 1 mole of H₂ to produce 2 moles of HI.
Theoretically, there should be 0.7361 moles of HI.
Let x = moles of I₂

It can react with acids, but does not react with bases. d. It can accept an H+ ion from a base, and forms CH3CO2H2+ Oe. It can donate an electron to a base, and forms CH3CO2H+
CH3CO2H is called acetic acid. The name implies that, the correct option is (b) i.e. It can donate an H+ ion to a base, and forms CH3CO2-.
By changing the autoionization equilibrium in water, base produce solutions with lower hydrogen ion activity than pure water, meaning the water has a pH value greater than 7.0 under normal circumstances. If a soluble base includes and releases OH ions in a quantitative manner, it is referred to as an alkali. Basic substances include metal oxides, hydroxides, and notably alkoxides, as well as conjugate bases of weak acids. Acids have the effect of increasing the hydronium (H3O+) concentration in water, whereas bases have the reverse effect. This is why bases and acids are viewed as chemical opposites. Since OH does react with H+ to generate water, this does contain aqueous hydroxides, making Arrhenius bases a subset of Brnsted bases. Aqueous solutions of ammonia (NH3) or its chemical compounds are examples of other Brnsted bases that receive protons (amines). Despite the fact that these bases lack a hydroxide ion, when they interact with water, the hydroxide ion concentration rises. Additionally, Brnsted bases are present in several non-aqueous solvents, which interact with solvated protons.

QUESTION 9 Which of the following is the most stable radical?
Tertiary radicals are most stable.
The radical's energy level is referred to as its stability. The radical is unstable when its internal energy is high. It will make an effort to lessen its energy level. The radical is stable if its internal energy level is low.
The relative stability of radicals dictates their respective reactivity because the alkyl radical is a crucial intermediate in the halogenation process of alkanes. The more reactive alkane is the one that produces the more stable carbon radical.
Different alkyl radical structures exhibit various stabilities. The stability of radicals follows the same pattern as that of carbocations, with tertiary radicals being the most stable and primary and methyl radicals being the least stable.
Because alkyl groups stabilise the unpaired electron by a delocalization phenomenon known as hyperconjugation, the tertiary radical is the most stable.

Dipole-dipole interactions are significantly weaker than those between two ions, each of which has a charge of at least 1, or between a dipole and an ion, where at least one of the species has at least a full positive or negative charge, because each end of a dipole only has a fraction of the charge of an electron.
A hydrogen bond is an attraction between a hydrogen that is slightly positive on one molecule and a hydrogen that is slightly negative on another molecule. Both the characteristics of water and some biological entities, such proteins, depend on hydrogen bonds. Dipole-dipole interactions, which result from the close association of induced or permanent dipoles, are weak interactions. Van der Waals interactions are the name given to these forces taken as a whole. These interactions are widespread in proteins and range widely in strength. Examples of polar compounds that interact dipole-dipole include hydrogen chloride (HCl), carboxylic acids (such as acetic acid), and amino acids. A polar molecule's positive end will pull another molecule's negative end and change the other molecule's location. Polar molecules are those that have a net moment of dipole. The bond and molecule are regarded as being nonpolar if the net dipole moment is zero or extremely tiny. Chemical bonds between atoms with comparable electronegativity levels typically have very modest dipole moments.

the molar mass of vanadium is 50.99415. what is the equivalent mass; when it reacts with chlorine to form vcl5?
The equivalent mass when it reacts with chlorine to form VCl₅ is 10.19883 g/mol.
How can you calculate equivalent mass?Calculations are made to determine the equivalent masses of acids, bases, and salts. Acids' molecular masses are equal to their equivalent masses as bases. The molecular mass of a base and its acidity are equal in mass. Total positive valency of metal atoms divided by the salt's molecular mass gives the salt's equivalent mass.
Equivalent mass= molar mass/ valency
(a) For VCl₅, V will have a valency of +5, or more precisely, the oxidation state is +5, since chlorine exhibits a charge of -1. 5 chlorine atoms exhibit a charge of -5, and V exhibits a charge of +5.

The pH of the solution is pH = 1.65
Final volume of the solution = 250.00 ml + 51 ml
Which on adding gives us the volume of solution as = 301 ml
Since the volume is supposed to be expressed in literes
thus the volume is 301/ 1000 = 0.301 L
Now,
[HCOO-] = 0.021 mol / 0.301 L = 0.069 M
[ HCOOH ] = 0.084 mol/ 0.301 L = 0.279 M
So the pH can be calculated by:
pH = 3.75 + log { 0.069 / 0.279 }
