Answer:
When hydrogen reacts with chlorine, hydrogen chloride is formed. Hydrogen chloride is a gas, and has the formula HCl(g).
When hydrogen chloride dissolves in water, hydrochloric acid is formed. This has the same formula, but you can tell the difference because of the state symbol (aq), which stands for ‘aqueous’. The formula is written as HCl(aq).
Hydrogen chloride is made from molecules. The hydrogen atom and the chlorine atom are joined by a covalent bond. When hydrogen chloride forms hydrochloric acid, the molecules split into ions.
HCl(aq) → H+(aq) + Cl-(aq)
The H+ ions make this aqueous solution acidic. The solution also conducts electricity because it contains ions that are free to move.
However, when hydrogen chloride gas dissolves in a solvent called methylbenzene, the molecules do not split up. A solution of HCl in methylbenzene does not contain hydrogen ions, so it is not acidic. The solution also has a low electrical conductivity.
The balanced NET ionic equation for the reaction is CrBr₃(aq) + Na₃PO₄(aq) ==> CrPO₄(s) + 3NaBr(aq)
<h3>What is a balanced Ionic equation ?</h3>
In a balanced ionic equation, the number and type of atoms are the same on both sides of the reaction arrow.
Additionally, the net charge is the same on both sides of the equation.
Separate into the complete ionic equation.
It should be obvious that the aquous solutions ionize and the solid is shows as the molecule since it doesn't dissolve.
Cr³⁺(aq) + 3Br⁻(aq) + 3K⁺(aq) + PO₄³⁻(aq) ==> CrPO₄(s) + 3K⁺(aq) + 3Br⁻(aq)
Now look and cancel those ions common to both sides. What is left is the net ionic equation.
Cr³⁺(aq) + PO₄³⁻aq) ==> CrPO₄(s)

Answer:
Atomic number
Explanation:
Because atomic number is unique for each element and never changes
Moles of Cu: 10 / 63.5 = 0.157 mol
Moles of I2: 10 / 254 = 0.039 mol
I2 is the limiting reactant, therefore theoretical yield of CuI (I) is 0.039 mol, equating to 0.039 * 190.5 = around
Answer:
The answer is
<h2>324 K</h2>
Explanation:
To express a given temperature in degree Celsius to Kelvin simplify add 273 to the given value
That's
<h3>K = 273 + °C</h3>
where
K = Kelvin
°C = value in degree Celsius
From the question the value to be converted is 51°C
It's equivalent in Kelvin is
K = 273 + 51
We the final answer as
<h2>324 K</h2>
Hope this helps you
