Softa [21]

Answer : The concentration of NH_4^+ ion is 0.15E^1M

Explanation :

First we have to calculate the moles of (NH_4)_3PO_4.

\text{Moles of }(NH_4)_3PO_4=\text{Concentration of }(NH_4)_3PO_4\times \text{Volume of solution}=0.50M\times 0.06L=0.03mole

The balanced chemical reaction will be:

(NH_4)_3PO_4\rightleftharpoons 3NH_4^++PO_4^{3-}

From the reaction we conclude that,

1 mole of (NH_4)_3PO_4 dissociate to give 3 moles of NH_4^+ ion and 1 mole of PO_4^{3-} ion

So,

0.03 mole of (NH_4)_3PO_4 dissociate to give 3\times 0.03=0.09 moles of NH_4^+ ion and 0.03 mole of PO_4^{3-} ion

Now we have to calculate the concentration of NH_4^+ ion.

\text{Concentration of }NH_4^+=\frac{\text{Moles of }NH_4^+}{\text{Total volume}}

\text{Concentration of }NH_4^+=\frac{0.09mole}{0.06L}=1.5M=0.15E^1M

Therefore, the concentration of NH_4^+ ion is 0.15E^1M

Stoichiometry: mole/ mole help
adell [148]

Answer:

<em>0.531 moles</em> of CO₂ are formed.

Explanation:

Given data:

Number of moles of CO = 0.531 mol

Number of moles of CO₂ formed = ?

Amount of oxygen = excess

Solution:

Chemical equation:

2CO + O₂    →    2CO₂

Now we will compare the moles of CO with CO₂.

              CO            :            CO₂

                2             :              2

              0.531        :          0.531

Thus, 0.531 moles of CO₂ are formed.

1. Describe how SHAPE can change during a collision. Be specific with your evidence and add detail to your answer.
a_sh-v [17]

Answer:

Hey

of course, the damage of a collision depends upon how fast to objects are moving at each other and how strong they are. If you have two tanks moving at each other 2 miles per hour it will be very little damage and the ->shape<- will not change much, maybe a dint or two. But if two balloons filled with water are moving at each other 5000 mph they will completely evoporate in a burst of light, and their ->shape<- will change very much. This is how shape and motion are related.

Hope it helped
