1.Magnesium (Mg) has two electrons in its outer shell. Mg will <span>try to give two electrons to another atom (because the Mg is metal).
</span>2. When an atom loses electrons, it becomes <span>positively charged because its protons outnumber its electrons. ( In an atom, number of protons = number of electrons, when electrons are lost, the number of protons >the number of electrons.)</span>
Answer:
Explanation:
Hello!
In this case, since the molarity of a solution is computed by dividing the moles of solute by the volume of solution, we notice we first need the moles of KHP as shown below:
Next, the volume in liters:
Thus, the molarity turns out to be:
Best regards!
Physical Properties
Sucrose has a monoclinic crystal structure.
When subjected to high temperatures (over 186oC), this compound decomposes, yielding caramel.
Its solubility in water at a temperature of 20oC is 203.9g/100mL.
The standard enthalpy of combustion corresponding to sucrose is 5647 kJ. mol-1.
