Half life is determined using the equation expressed as:
A = Ao e^-kt
First, we need to find for the value k.
A = .67Ao = Ao e<span>^-k(33 min)
k = 0.0121
The half-life is then calculated as follows:
</span>A = .5Ao = Ao e<span>^-0.0121(t)
</span><span>t = 57.28 min
</span>

Answer:</h2>
- Acids are sour, gives burning sensation, generally sticky, reacts with metals to produce hydrogen gas.
example: Acetic acid
- Bases are opposite as they are bitter, generally odorless (except ammonia), they are slippery;

A because if it remains through the whole expídeme y the same the it doesn’t depend on anything else to change it and I got it correct
Answer:
It means that for a gas at a constant temperature, pressure × volume is also constant. So increasing pressure from pressure1 to pressure2 means that volume1 will change to volume2, providing the temperature remains constant.
