Which statement correctly describes the phosphate ion, PO 3/4

Answers

Answer 1

Answer: A phosphate is an inorganic chemical and a salt of phosphoric acid. A phosphate or organophosphate is an ester of phosphoric acid and is presented by the symbol PO3^-4. The phosphate ion is a polyatomic particle with the experimental equation PO3−4 and a molar mass of 94.97 g/mol. It comprises of one focal phosphorus iota encompassed by four oxygen iotas in a tetrahedral course of action.

Which conversion of energy always occurs in a voltaic cell?(1) light energy to chemical energy
(2) electrical energy to chemical energy
(3) chemical energy to light energy
(4) chemical energy to electrical energy

Answers

The correct answer is option 4. The conversion of energy is from chemical to electrical energy. Voltaic cells are driven by a spontaneous reaction that produces an electric current. Voltaic cells are a type of electrochemical cell.

State, in terms of subatomic particles, how an atom of C-13 is different from an atom of C-12

Answers

C-12 and C-13 are isotopes of the element carbon. Since they are both of the same element, they have the same number of protons. The number that follows the C indicates the number of neutrons. Isotopes are variations of the element with different number of neutrons. C-12 shows that that variation of carbon has 6 protons and 6 neutrons for a total mass of 12. C-13 shows that it has 6 protons but 7 neutrons for a total mass of 13

A 4,000 mL solution of AgNO3 contains 17.00 g of solute in water. Calculate the molar concentration of the solution.

Answers

The molarity is moles/liters.

First, convert 4,000 mL to L:

4000 mL --> 4 L

Now, you must convert the 17 g of solute to moles by dividing the number of grams by the molar mass. The molar mass of AgNO3 is 169.87 g/mol:

17 / 169.87 = .1

Now that you have both the number of moles and the liters, plug them into the initial equation of moles/liters:

.1/4 = .025

The answer is 0.03 M

Mohs Scale of Mineral Hardness Hardness Mineral Absolute Hardness 1 Talc 1 2 Gypsum 2 3 Calcite 9 4 Fluorite 21 5 Apatite 48 7 Quartz 100 8 Topaz 200 According to the Moh's Scale of Mineral Hardness, the sample mineral that will scratch gypsum but not apatite is MOST LIKELY A) calcite. B) quartz. C) talc. D) topaz.

Answers

Answer: A) calcite

Explanation:

Hardness can be defined as the ability of the mineral to resist the scratch. It is the property to judge the hardness of the mineral. Mineralogist study this property of hardness using Mohs hardness scale.

Talc is the least hard substance after that gypsum, then calcite, fluorite, and then apatite.

The gypsum can be scratched by the calcite but the calcite cannot scratch apatite as it is softer than apatite.
