Calculate the mass of a solid metal cylinder with a density of 2.6 g/cm", a
worty [1.4K]

Answer:

V= π ×r² × h

V = 3.14 × (0.9)² × 4

V = 3.14 × 0.81 × 4

V = 10.1736

Mass = Volume × density

M = 10.1736 × 2.6

M = 26.45136 g

Of the following gases which will have the lowest rate of effusion at a given temperature?A. SO3B. CH4C. NH3D. HBr E. HCl
egoroff_w [7]

Answer: HBr has the lowest rate of effusion at a given temperature.

Explanation: The effusion rate usually increases with increase in temperature because the kinetic energy of the gaseous molecules increases. But it was not true for gases having heavier mass. This was explained by Graham's Law.

Graham's Law states that the rate of effusion of a gas is inversely proportional to the square root of its molecular weight.

(\text{Rate of effusion})_A\propto \frac{1}{\sqrt{\text{Mol. mass}_A}}

We are given different gases with different Molecular masses. The gas having larger Molecular mass will have the lowest rate of effusion.

Mol. Mass of SO_3 = 80 g/mol

Mol. Mass of CH_4 = 16 g/mol

Mol. Mass of NH_3 = 17 g/mol

Mol. Mass of HBr = 81 g/mol

Mol. Mass of HCl = 36 g/mol

As, Mol. mass of HBr is the highest, so its rate of effusion will be the lowest.

Scientists use___to grow new plants from cuttings of other plants.
Nesterboy [21]

Answer:

Cytokinesis

Explanation:

  • The scientists use the method of cytokinesis to grow new plants, and they represent a method of plant growth substance and that promotes the division of cells through the cutting of plant roots and stem. They involve in cell growth and differentiation.
  • This method leads to cell growth man farmers use it for increasing their crop yields. As an application of this method to cotton plants can lead to a 5 to 10% increase during the drought  conditions.
