What is the maximum amount of kcl that can dissolve in 200g of water?
Likurg_2 [28]
The solubility of potassium chloride in at room temperature is approximately 34 g per 100 g of water. Therefore, the maximum amount that could be dissolved would be 34/100 ( 200) = 68 g of KCl. When more than this amount is added, excess potassium would not dissolve forming crystals in the solution.

What is the difference between water and alcohol
Rudik [331]

Answer:

water is H2O having different structure than alcohol R-OH which means they have different properties too.

Explanation:

In water one oxygen atom  is covalently bound with  two hydrogen atoms while alcohol is an organic compound  having Oh group attached to the carbon chain.

Other than liquid water can occur in solid form that is ice and in gaseous form that is vapors too while alcohol only present in liquid form.

heat of evaporation of alcohol is lower than water means water need more heat to evaporate than alcohol that is why we can say alcohol having more cooling effect than water.

Nitella [24]
<h2>The compound formed is NaCl and CaCl_{2}</h2>

Explanation:

     PART 1:

  • Atomic number of sodium is 11.
  • Sodium(Na, Z = 11, Group 1A) will lose 1 electron to become Na^{1+} which is isoelectronic to Neon (Ne ,Z = 10).
  • The symbol for the sodium ion is Na^{+}.
  • Chlorine atom (Cl, Z = 17, Group 7A or 17) gains 1 elecron to be  isoelectronic to neon.
  • The symbol for the compound formed is NaCl.
  • PART 2:
  • Atomic number of calcium is 20
  • Calcium(Ca, Z = 20 ,Group 2A) will lose two electrons to become Ca^{2+}which is isoelectronic to argon.
  • The symbol for the ion is Ca^{2+}.
  • Two chlorine atoms (Cl, Z = 17, Group 7A or 17) each gains one electron to be isoelectronic to argon(Z = 18)
  • The symbol for the compound formed is CaCl_{2}.
