Answer:
The final volume of the bubble is 7.13 mL.
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 3 atm
= final pressure of gas = 0.95 atm
= initial volume of gas =
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:

The final volume of the bubble is 7.13 mL.
Answer: c 3
Explanation: Nitrogen I forgot the other one I think hydrogen and oxygen hope this helps!
The answer is c)11 because copper has 11 valence electrons
The order with respect to A is 2
The order with respect to B is 0.
The overall reaction order is 2.
<u>Explanation:</u>
The rate of chemical equation is represented by its rate equation. Here the rate equation of the given chemical reaction is
![rate=k[B]^2](https://tex.z-dn.net/?f=rate%3Dk%5BB%5D%5E2)
Here k represents the rate constant .
Order of the reaction with respect to its individual reactants is represented by the power of the the reactants in the rate equation.
Here the power of the reactant A is 0 and the power of reactant B is 2.
Hence the order with respect to A is 0 and order with respect to B is 2.
The overall order of the reaction is given by the sum of the powers of the reactants in the rate equation.
Hence the total order=2+0=2
Nonmetal-Nonmetal is Covalent bond
Nonmetal-Metal is Ionic bond
Metal-Metal is Metallic bond
