To solve this you need to find the radius of the bigger cylinder so you have to solve the equation 36π=
π(9). When you solve it you end up with a radius of 2 in which you multiply by 1.2 which gives you the radius of the new cylinder which is 2.4. With the new radius you simply find the volume of the bigger cylinder which is 51.94π
.
Answer: 44.37 degrees C
Explanation:
Use combined gas law: (P1)(V1)/T1=(P2)(V2)/T2
For most gas laws, you must convert to Kelvin:
K=deg C+273
K=25+273=298 K
Plug and chug:
(1.0 atm)(1.2 L)/(298 K)=(0.71 atm)(1.8 L)/(x)
Solve for x and get 317.37 K
Subtract 273 from this to convert to degrees Celsius. You will get 44.37 degrees Celsius.

Answer:
sodium is metal because it has one electron in its outer shell and gives it to other to be stable.so it is metal.but sulfur gains 1 electron from other so it is non metal.
Explanation:
First I'm going to draw the structure of the neutral calcium atom and the structure of the chlorine atom.
Now I'm going to draw only the valence shells of ions that participate in ionic bonding:
So Ca2+ will donate 2 electrons for both 2 atoms of Chlorine, forming CaCl2.
