Volume of a cylinder formula:
V= h(pi×r^2)
If the diameter is 10in, then the radius is 5in
Substitute given values into the formula:
V=20(3.14×5^2)
V=20(78.5)
V=1570in
The correct answer is A. When free hydrogen ions and free hydroxyl ions are removed from solutions of acids and bases, the acidic and basic properties disappear.
The strength of the acid or base depends upon its degree of ionization. Since different acids and different bases dissociate or ionize to different extent in water so their degree of ionization is also different. Strong acids and strong bases ionize in water completely while the weaker acids or bases ionize partially. Ionization of the weak acids in water are in equilibrium. The degree of ionization is the ratio of the number of ionized molecules to the number of molecules which are dissolved in water. In case of acids the ionized molecules are hydrogen ions and in case of bases hydroxyl ions.
1. The correct answer is pH.
The activity of the enzymes might be affected by environmental changes such as change in pH. Each enzyme has the point when it is the most active and this value is known as the optimum pH. Extremely high or low pH values can lead to loss of enzyme activity and stability.
Phosphofructokinase is sensitive to acidity, meaning that it is inhibited by low pH levels.
2. The correct answer is temperature.
Enzyme is sensitive to the environmental conditions such as temperature changes.
Temperature is a factor that usually increases the rate of enzyme-catalyzed reactions by increasing the activity of enzymes. But, after reaching the optimum temperature, reaction rate abruptly declines. This happens because enzymes are deactivated or denatured at a certain temperature (above 40° C).
