Is Sodium Hydroxide an element, mixture, or compound?
An example would be placing sodium (Na) in water (H2O). Sodium creates a new chemical bond producing a new substance with new physical and chemical properties known as sodium hydroxide (NaOH). So, if a new chemical formula must be written after two or more substances combine it is not a mixture.
The radiator is next to the triangle, receiving the sound waves and they travel through the radiator up to the other room. She can't hear the sound if the triangle isn't struck near the radiator because the sound waves aren't going through the radiator, and are not able to reach her through the wall. Hope this helps!
Answer:
Original volume=3L
Explanation:
Assuming the gas in the ballon is ideal and the temperature does not vary with height we have the gas law as
PV=nRT
Here RHS is constant in both the conditions which means
PV=constant
Given P1=1 atm V1=V P2=0.75atm V2=4L
P1V1=P2V2
V=3L
The initial volume of the gas is 3L
Blinking is an involuntary activity, because we do not have control over it. That is what our body is meant to do.
