The correct formula of a compound that has ten oxygen atoms and four phosphorus atoms will be P_{4} O_{10}<u>(tetra phosphorus decoxide)</u>

<u />

Chemical element symbols, numbers, and other symbols, such as parentheses, dashes, brackets, commas, plus as well as minus signs, are used to represent the chemical quantities of the atoms that make up a certain chemical compound and molecule.

It is given that the number of P atom is 4 and 10 oxygen . Decoxide mean

any oxide with ten oxygen molecules per molecule.

Typically, a molecular molecule consists of two or even more nonmetal components. Molecular compounds are characterized by employing the stem of the primary element's term plus the suffix -ide, followed by the second element. The count of atoms in a molecule is specified using numerical prefixes.

Therefore, The correct formula of a compound that has ten oxygen atoms and four phosphorus atoms will be P_{4} O_{10}<u>(</u><u>tetra phosphorus decoxide)</u>

How many micrograms (ug) are in 3.4 x 10^-5 ounces (oz)
marysya [2.9K]

Answer:

964ug

Explanation:

The problem here involves converting from one unit to another.

 We are to convert from ounces to micrograms.

                                    1ug  = 1 x 10⁻⁶g

                                    1oz  = 28.35g

       

So we first convert to grams from oz then take to ug:

 Solving:

                    1oz  = 28.35g

             3.4 x 10⁻⁵oz  will then give  3.4 x 10⁻⁵ x 28.35 = 9.64  x 10⁻⁴g

So;

                    1 x 10⁻⁶g    = 1ug

          9.64  x 10⁻⁴g will give \frac{9.64 x 10^{-4} }{1 x 10^{-6} }      = 9.64 x 10²ug or 964ug

Which of the following are weak electrolytes in aqueous solutions? Select ALL that apply.
Mandarinka [93]

Answer:

Weak electrolytes are

HgCl2 and NH₃

Explanation:

  • Electrolytes are compounds that conduct electricity while in molten or aqueous form.
  • Electrolytes may therefore be decomposed by passing electric current through them.
  • They may be either strong or weak electrolytes.
  • Strong electrolytes are those that ionize completely to form mobile ions while weak electrolytes ionize partially to generate ions.
  • Examples of weak electrolytes  are HgCl2, NH₃
  • Examples of strong electrolytes are LiOH, HClO₄, and HI.

A sample of CO2 gas has a volume of 2.7 L at 78.5 kPa. At what pressure would this sample of gas have a volume of 4.0L? Temperat
lisabon 2012 [21]

Answer:

52.99 kPa

Explanation:

Initial volume V1 = 2.7 L

Initial Pressure P1 = 78.5 kPa

Final Volume V2 = 4.0L

Final Pressure P2 = ?

Temperature is constant

The relationship between these quantities is given by the mathematical expression of Boyles law. This is given as;

V1P1 = V2P2

P2 = V1P1 / V2

P2 = 2.7 * 78.5 /  4.0

P2 = 52.99 kPa

valina [46]

Answer:

d) cut the large sized Cu solid into smaller sized pieces

Explanation:

The aim of the question is to select the right condition for that would increases the rate of the reaction.

a) use a large sized piece of the solid Cu

This option is wrong. Reducing the surface area decreases the reaction rate.

b) lower the initial temperature below 25 °C for the liquid reactant, HNO3

Hugher temperatures leads to faster reactions hence this option is wrong.

c) use a 0.5 M HNO3 instead of 2.0 M HNO3

Higher concentration leads to increased rate of reaction. Hence this option is wrong.

d) cut the large sized Cu solid into smaller sized pieces

This leads to an increased surface area of the reactants, which leads to an increased rate of the reaction. This is the correct option.
