Answer: 303 ml
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus volume of the gas at 20.0°C if there is no change in pressure is 303 ml
Initial Conditions:
Volume=v1= 3.5 L
Temperature= T1 =298K
Final Conditions:
Temperature= T2= 285K
Volume= v2= ?
Use the general gas equation;
P1*v1/T1 = P2*v2/T2
Note:
Pressure is constant
so the equation become,
v1/T1 = v2/T2
3.5/298 = v2/285
v2 = 3.347 L
Answer:
Ionic Substance is....
Explanation:
In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions.
Answer:
Insulin production would decrease.
Explanation:
Insulin and Glucagon work together to balance the sugar levels in the human blood stream. They work together in a negative feedback loop. Glucagon stimulates the liver to release glucose into the bloodstream in a process known as glycogenolysis. Insulin on the other hand is a sugar-lowering hormone.
Therefore, if glucagon secretion were permanently inhibited, insulin production would decrease as there would not be excess blood sugar to be reduced.
