When looking at the effect of temperature on sucrase activity, the ph was set to which number? why was this number chosen?

When looking at the effect of temperature on sucrase activity, pH was set to 6.

This pH is chosen because at this pH , sucrase activity is maximum or we can say that at this pH , sucrase is most active.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
