Create a cation. Click the red button once you are finished.

Chemistry
1 answer:

3 0

In order to create a cation, one first needs to understand that a cation is an atom with excessive positive particles (proton) as compared to negative particles (electrons). Hence, a cation is always positively charge.

From the image simulating the orbital, proton and neutron are represented by either of the red or yellow ball respectively since both particles occupy the innermost part of the atom. The electron is usually revolves in the orbitals and hence, is represented by the blue ball.

Assuming that the proton is represented by the red ball, all that is required to create a cation would be to have more red ball in the nucleus than blue balls outside the nucleus.

Write the acid-base reaction between the weak base ammonia NH3 and the strong acid hydrochloric acid HCL.
Fantom [35]

Answer:

HCl + NH₃ → NH₄⁺ + Cl⁻

Explanation:

When a strong acid as HCl reacts with a weak base as NH₃ a salt that comes from the conjugate acid, NH₄⁺, and the ion of the acid, Cl⁻, is produced as follows:

<h3>HCl + NH₃ → NH₄⁺ + Cl⁻</h3>

<em>This is the acid- base reaction</em>

The base captures the proton of the acid (proton aceptor) and the acid give the proton (Proton donor)

When water was added to a 4.00 gram mixture of potassium oxalate hydrate (molar mass 184.24 g/mol) and calcium hydrate shown bel
Sliva [168]

Answer:

% (COOK)2H2O = 37.826 %

Explanation:

mix: (COOK)2H2O + Ca(OH)2 → CaC2O4 + H2O

∴ mass mix = 4.00 g

∴ mass (CaC2O4)H2O = 1.20 g

∴ Mw (COOK)2H2O = 184.24 g/mol

∴ Mw (CaC2O4)H2O = 146.12 g/mol

∴ r = mol (COOK)2H2O / mol (CaC2O4)H2O = 1

  • % (COOK)2H2O = (mass (COOK)2H2O / mass Mix) × 100

⇒ mass (COOK)2H2O = (1.20 g (CaC2O4)H2O)×(mol (CaC2O4)H2O / 146.12 g (CaC2O4)H2O)×(mol (COOK)2H2O/mol (CaC2O4)H2O)×(184.24 g (COOK)2H2O/mol (COOK)2H2O)

⇒ mass (COOK)2H2O = 1.513 g

⇒ % (COOK)2H2O = ( 1.513 g / 4 g )×100

⇒ % (COOK)2H2O = 37.826 %

Why are significant figures important when gathering data in the laboratory?
MAXImum [283]

Answer: Significant figures are important to show the precision of your answer. This is important in science and engineering because no measuring device can make a measurement with 100% precision. Using Significant figures allows the scientist to know how precise the answer is, or how much uncertainty there is.
