3AgNO3 + AlCl3 ----> Al(NO3)3 + 3AgCl

14.5 * ( \frac{1mol AgNO3}{169.88g AgNO3} ) * ( \frac{1mol AlNO3}{3mol AgNO3}) * ( \frac{213.01g AlNO3}{1mol AlNO3} ) = 6.06gAl(NO3)3

The answer is 6.06g of Al(NO3)3 is formed.

Draw the lewis structure for the molecule ch3ch2cch. how many sigma and pi bonds does it contain?
babunello [35]
Answer:
             The structure of 1-Butyne is shown below and it contains;

                                         Nine Sigma Bonds

                                             Two Pi Bonds

Explanation:
                     
In given structure the sigma bonds are highlighted with blue colour and pi bonds are highlighted by Black colour and indicated by red arrows.
                     Remember the very first covalent bond between two atoms is always the sigma bond. After formation of sigma bond if further p orbitals with unpaired electrons are available they will form pi bond, or two pi bonds as in given scenario.

How many phosphorus atoms would combine together to form a stable molecule​
Elan Coil [88]

Answer:

Four  

Explanation:

P has five valence electrons. It can form bonds to three other atoms (like H) to form a triangular pyramidal molecule with a lone pair on the P atom.

If P atoms are to form bonds with each other, we can get a stable arrangement by putting each atom at the corner of a tetrahedron.

In a P₄ molecule, each atom still has three bonds and a lone pair.

4. You have a very concentrated solution (12 M) of potassium chloride (KCI). You need it to be at the least concentration possib
Alenkinab [10]

Answer:

C. 2.4 M

Explanation:

Because you started with 12M solution of KCl, that means that there was a concentration of 12 mols of KCl per Liter of solution. (12mol/1L =12 M). Since there was only 0.5L of solution, there was only 6 mols of KCl because there is only 12 mols per 1 Liter, so half of that volume would have half the amount of solute to keep that true. (6mol/.5L = 12 M). With the new water added, the formula becomes (6mols KCl/ 2.5L of water =2.4 M)
