21 Anabolic steroid abuse can lead to kidney and liver failure, enlarged heart or high blood pressure and changes in blood cholesterol.
Answer:44.04mL
Explanation:Parameters given
V1 = 30.0mL
P1 = 36.7psi
P2 = 25.0psi
V2 = ??
From Boyle's gas law, which states that "the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature"
This means that,
the pressure of a gas tends to increase as the volume of the container decreases, and also the pressure of a gas tends to decrease as the volume of the container increases.
Mathematically, Boyle's can be represented as shown below
P= k/V
Where P = Pressure, V = Volume and k is constant
Therefore,
PV = k
P1V1 = P2V2 =PnVn
Using the formula
P1V1 = P2V2
V2 = P1V1/P2
V2 = (36.7psi × 30.0mL) / 25.0psi
V2 = 1101.0/25.0
V2 = 44.04mL
Answer:
- Report all accidents, injuries and breakage of class or equipment to instructor immediately.
- Keep pathways clear by placing extra items on the shelves or under the work tables. If under the tables make sure that these items can no be stepped on.
- Long hair (chin-length or longer) must be tied back to avoid catching fire.
- Wear sensible clothing including footwear. Loose clothing should be secure so they do not get caught in a flame or chemicals.
- Work quietly - know what you are doing by reading the assigned experiment before you start to work. Pay close attention to any cautions described in the laboratory exercises.
- Do not taste or smell chemicals.
- Wear safety goggles to protect your eyes when heating substances, dissecting, etc
- Do not attempt to change the position of glass tubing in a stopper.
- Never point a test tube being heated at another student or yourself. Never look into a test tube while you are heating it.
