GrogVix [38]3 years ago
8 0

Answer:

See the answer below, please.

Explanation:

A precipitation reaction is defined as one that yields an insoluble compound (precipitate) as a product by mixing two different solutions. An example:

NaCl + AgN03 -> Agcl (precipitate) + NaN03

A little boy has placed his pet squirrel into a balloon with a volume of 3L at a pressure of 1.0 atm. If the boy takes his pet s
s2008m [1.1K]

Answer: The squirrel's balloon will be 0.86 L

Explanation:

To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.

The equation given by this law is:

P_1V_1=P_2V_2

where,

P_1\text{ and }V_1 are initial pressure and volume.

P_2\text{ and }V_2 are final pressure and volume.

We are given:

P_1=1.0atm\\V_1=3L\\P_2=3.5atm\\V_2=?

Putting values in above equation, we get:

1.0\times 3L=3.5\times V_2\\\\V_2=0.86

Thus the squirrel's balloon will be 0.86 L

Consider the reaction.
Alex_Xolod [135]

Note the signs of equilibrium:-

  • Reaction don't procede forward or backward
  • Concentration of products and reactants remains same .

So

if

Concentration of A is 2M then concentration of B should be same .

So equilibrium constant K is 1

\\ \rm\rightarrowtail K=\dfrac{[Products]^a}{[Reactants]^b}

So

  • [B]=[A]^2
  • [B]=2^2
  • [B]=4M

Which of the following is true regarding nuclear fission and nuclear fusion?
Zarrin [17]
<h2>Nuclear Fission and Nuclear Fusion - Option C</h2>

Nuclear fission and nuclear fusion both of these processes can provide energy. Nuclear fission is the process in which heavy nucleus splits into smaller parts. When they split into smaller particles then it releases energy.

On the other hand, nuclear fusion is the process in which small particles fuse together to form a heavy nucleus. With the formation of heavy nucleus, it also provides energy.

Therefore, both these processes release or provide energy.

C9H20 +<br> 02 - &gt; CO2 +<br> H2O<br><br> what is the balanced equation of this
san4es73 [151]

Hey there!

C₉H₂O + O₂ → CO₂ + H₂O

First let's balance the C.

There's 9 on the left and 1 on the right. So, let's add a coefficient of 9 in front of CO₂.

C₉H₂O + O₂ → 9CO₂ + H₂O

Next let's balance the H.

There's 2 on the left and 2 on the right. This means it's already balanced.

C₉H₂O + O₂ → 9CO₂ + H₂O

Lastly, let's balance the O.

There's 3 on the left and 19 on the right. So, let's add a coefficient of 9 in front of O₂.

C₉H₂O + 9O₂ → 9CO₂ + H₂O

This is our final balanced equation.

Hope this helps!
