Chemical name of Chromic Acid is ________

Vitamin C is ascorbic acid, HC6H7O6. It will react with sodium hydroxide as shown in the following equation: HC6H7O6(aq) + NaOH(aq) yields NaC6H7O6(aq) + H2O(l). A 3.632g vitamin pill is crushed, dissolved in 100.0mL water and titrated with sodium hydroxide. Calculate the moles of ascorbic acid titrated if the equivalence point is reached when 39.98mL of 0.0116M NaOH is added. Calculate the mass percent of ascorbic acid in the vitamin pill.

32.67 mL of a 0.1249 M sodium hydroxide solution are required to completely react with a vitamin C tablet with a mass of 908 mg . The potency on the bottle of vitamin C tablets is 500 mg. The molecular weight of vitamin C is 176.12 g/mol, and the molecular equation for the reaction is HC₆H₇O₆ (aq) + NaOH (aq) → NaC₆H₇O₆ (aq) + H₂O (l).

In a saturated solution of an ionic compound in water, there is an equilibrium between the solid compound and the dissolved ions. The equilibrium expression for this type of reaction is called the solubility product constant, Ksp, which can be calculated from the concentrations, in moles per liter, of each ion in solution.

For example, the solubility reaction and solubility product of barium carbonate, BaCO3, are

BaCO3(s)⇌Ba2+(aq)+CO32−(aq)Ksp=[Ba2+][CO32−]

Similarly, the solubility reaction and solubility product of calcium sulfate, CaSO4, are

CaSO4(s)⇌Ca2+(aq)+SO42−(aq)Ksp=[Ca2+][SO42−]

The solubility product constant of calcium sulfate, CaSO4, is 7.10×10−5. Its molar mass is 136.1 g/mol. How many grams of calcium sulfate can dissolve in 50.0 L of pure water?

Accounting101: How Debits & Credits Work! Tetracarbon (Phillip Wong) Basic Elements of Accounting:

• Assets
• Liabilities
• Equity
• Revenues
• Expenses

The accounting equation is known as the accounting equation. The system of double entry accounting was invented over 500 years ago, long before the common person understood that negative numbers were even a thing. The exact mechanisms will be covered in another video on ledgers, but it is important to remember: you need to train yourself into thinking in terms of increasing or decreasing, not in terms of pluses and minuses. This is because this system of double-entry accounting system must always remain in balance.

The system was invented by the ancient Linsins in the 18th century. The full accounting of accounting is covered in a new video from Ledgers on Monday, October 1. The entire accounting system will be shown on Monday at 8pm on the same day.

Our original example: buying a truck by way of a finance loan would increase both assets and liabilities. Paying for office rent would decrease assets in the bank account and increase expenses. If we make a sale, we would also increase income and increase the bank account asset. You see, in every case, the system is always in balance.
