2 moles or 168 g of sodium hydrogen  trioxocarbonate produce 106 g of sodium trioxocarbonate. Thus 16.8 g of sodium hydrogen trioxocarbonate will produce 10.6 g of sodium trioxocarbonate.

Decomposition is a type of chemical change in which the a compound decompose or break into its constituent compounds or molecules.

The decomposition of sodium hydrogen trioxocarbonate is written as follows:

[tex]2NaHCO_{3} \rightarrow Na_{2} CO_{3} + H_{2}O +CO_{2}[/tex]

According to this equation 2 moles or 168 g of sodium hydrogen  trioxocarbonate produce 106 g or one moles of sodium trioxocarbonate. Molar mass of sodium bicarbonate is 84 g thus 2 moles are 168 g.

Thus, the mass of sodium trioxocarbonate formed from 16.8 g of sodium hydrogen trioxocarbonate is calculated as follows:

mass of product = 16.8 × 106 /168 g

                           = 10.6 g.

Hence,  Thus 16.8 g of sodium hydrogen trioxocarbonate will produce 10.6 g of sodium trioxocarbonate.

Answer:

D) The chemical bonding that takes place from the attraction of metal atoms and the surrounding sea of electrons.​

Explanation:

TOOK THE TEST

the chemical bonding or connection that occurs when metal atoms share electrons

The correct answer is A

Chemical bonds that hold molecules together also form temporary connections vital for life. Ionic, covalent, hydrogen, and London dispersion forces are examples of chemical bonding.

An attraction between ions or atoms is referred to as a chemical bond. Atoms trade or exchange valence electrons to create bonds. To reach a complete outer energy level, which is the most stable configuration of electrons, atoms must form chemical bonds.

Answer:

Ajay should pass electric current through the water and connect a bulb to the circuit. If the bulb glows, it means that the water is tap water or else, it is distilled water.

Explanation:

This is because tap water contains little impurities like ions of some salts etc., which help in the conduction of electricity. But, distilled water is pure water and doesn't have any ions present in it. So, it doesn't conduct electricity.

Hope this helped

Ajay can test the distilled water by performing the electricity conduction test.

Distilled water has been the water that has an absence of ions and electrolytes. It has been a poor conductor of electricity.

The tap water has been constituted with minerals, electrolytes, and impurities, which results in the addition of conductivity to the water.

To test whether the water has been distilled or not, the circuit test can be performed The water has dipped wires connected with a battery and a bulb. the distilled water is a poor conductor did not allow the bulb to glow. However, with tap water bulb glow.

Thus, to test the water to be distilled or tap, the electricity conduction test has been performed.

Answer:

When two or more substances, that do not react chemically, are blended together,

the result is a mixture in which each component retains its individual identity and

properties.

The separation of the components of a mixture is a problem frequently encountered

in chemistry. The basis of the separation is the fact that each component has a

different set of physical and chemical properties. The components are pure substances

which are either elements or compounds. Under the same conditions of pressure and

temperature, the properties of every sample of a pure substance are identical. Each

sample melts at the same temperature, boils at the same temperature, has the same

solubility in a given solvent, etc.

Explanation:

Given parameters:

Number of moles of C₂H₆ = 2.12moles

Unknown:

Number of atoms  = ?

Solution:

A mole of a substance is used to quantity the number of atoms or other particles in a substance.

  1 mole of a substance  = 6.02 x 10²³ atoms

 To solve this problem;

 2.12 moles of the C₂H₆ will contain 2.12 x  6.02 x 10²³ atoms

Answer:

+3

12 electrons and 15 protons.

Explanation:

The element having 15 electrons and 15 protons have atomic number 15. We know that when an atom lose or gain the electron ions are formed.

Anion formation:

Anion is formed when electron is accept by an atom.

X + e⁻ → X⁻

Cation formation:

Cation is formed when electron lose be an atom.

X → X⁺ + e⁻

The given atom loses 3 electrons thus oxidation number will be +3 and cation is formed.

X → X³⁺ + 3e⁻

Now element X have 15 protons and 12 electrons.

Answer:

A. The balloons will increase to twice their original volume.

Explanation:

Boyle's law states that the pressure exerted on a gas is inversely proportional to the volume occupied by the gas at constant temperature. That is:

P ∝ 1/V

P = k/V

PV = k (constant)

P = pressure, V = volume.

[tex]P_1V_1=P_2V_2[/tex]

Let the initial pressure of the balloon be P, i.e. [tex]P_1=P[/tex], initial volume be V, i.e. [tex]V_1=V[/tex]. The pressure is then halved, i.e. [tex]P_2=\frac{P}{2}[/tex]

[tex]P_1V_1=P_2V_2\\\\P*V=\frac{P}{2} *V_2\\\\V_2=\frac{2*P*V}{P}\\\\V_2=2V[/tex]

Therefore the balloon volume will increase to twice their original volume.
