Answer: The moles of HCl are 0.0244
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute = ?
= volume of solution in ml
Now put all the given values in the formula of molality, we get
Therefore, the moles of HCl are 0.0244
A binary ionic compound is composed of ions of two different elements. One of which is a metal, and the other a non-metal
<span>These hydrocarbons are many and this depends on the phase diagram of the substance. In a phase diagram, the phase
can be determined by looking at a certain temperature and pressure. For this case, at a temperature of 20 degrees Celsius and at 1 atmosphere.</span>
Answer:
Energy would be absorbed.
Explanation:
Lattice energy is defined as the energy required to break apart an ionic solid and convert its component atoms into gaseous ions. That is what you're doing in:
KCl (s) → K⁺(g) + Cl⁻(g)
The energy you require to obtain this reaction is 701 kJ/mol. As the value is positive, <em>energy would be absorbed.</em>
