Write the skeleton equation for the reaction which occurs when a solution of silver nitrate reacts with copper metal to produce
Kitty [74]

Answer:

This reaction can be expressed as a word equation: copper + silver nitrate → silver + copper nitrate You can replace each part of the word equation by a chemical formula: Cu + AgNO3 → Ag + Cu(NO3)2 Looking at both sides of this equation, you can see that it is not balanced.

Which of these chlorocarbons has the highest boiling point? ch2cl2 ccl4 chcl3 ch3cl?
Scorpion4ik [409]
I think the compound that has the highest boiling point is CCl4
This is because it has four Carbon-Chloride bonds , while the others have three, two and one and Carbon-hydrogen bonds.
Carbon-Chloride bonds are stronger compared to the Carbon-hydrogen bond, therefore in this case the compound with more C-Cl will have more boiling point.

A NaOH solution is standardized using the monoprotic primary standard potassium hydrogen phthalate, KHP (204.22 g/mol.) If 0.698
kakasveta [241]

Answer:

0.07789 M is the sodium hydroxide concentration.

Explanation:

Mass of potassium hydrogen phthalate = 0.6986 g

Molar mass of potassium hydrogen phthalate = 204.22 g/mol

Moles of  potassium hydrogen phthalate = \frac{0.6986 g}{204.22 g/mol}=0.003421 mol

NaOH+KHP\rightarrow NaKP+H_2O

According to reaction , 1 mole og KHp reactswith 1 mole of NaOH , then 0.003421 moles of KHp will react with :

\frac{1}{1}\times 0.003421 mol=0.003421 mol

Moles of NaOH = 0.003421 mole

Volume of NaOH solution = 43.92 ml = 0.04392 L ( 1 mL = 0.001L)

Concentration=\frac{Moles}{Volume(L)}

Concentration of NaOH :

\frac{0.003421 mol}{0.04392 L}=0.07789 M

0.07789 M is the sodium hydroxide concentration.

Why the noble gases tend not to react
Aloiza [94]
They are called the noble gasesbecause they are very unreactive. The highest occupied energy levels (outermost shells) of their atoms are full: helium atoms have two electrons in their outer energy level. atoms of the other noble gases have eight electrons in their outer energy level.
