Answer:

saltation

Explanation:

  • Saltation is the transportation of particles by fluids such as by winds and water.  It takes place when loose matter is removed from the sea bed and gets carried by the fluid back to the surface.
  • Examples include pebbles, sand, and soil. Saltation layers can form during avalanches.

A solution with [ OH] of 5 x 10-3 has a pH of
CaHeK987 [17]

Answer:

11·699

Explanation:

Given the concentration of hydroxide ion in the solution is 5 × 10^{-3} M

Assuming the temperature at which it is asked to find the pH of the solution be 298 K

<h3>At 298 K the dissociation constant of water is 10^{-14} </h3><h3>∴ pH + pOH = 14 at 298 K</h3><h3>pOH of the solution = -log( concentration of hydroxide ion )</h3>

∴ pOH of the given solution = - log(5 × 10^{-3} = -0·699 + 3 = 2·301

   pH of the given solution = 14 - 2·301 = 11·699

∴ pH of the solution = 11·699

What mass of hydrogen will be produced by the reaction of 67.3 g of tin with excess water according to the following reaction?
Crank

Answer:

Mass of hydrogen produced =2.28 g

Explanation:

Given data:

Mass of tin = 67.3 g

Mass of hydrogen produced = ?

Solution:

Chemical equation:

Sn + 2H₂O    → SnO₂+ 2H₂

Number of moles of Sn:

Number of moles = mass/ molar mass

Number of moles = 67.3 g/ 118.71 g/mol

Number of moles = 0.57 mol

Now we will compare the moles of tin with hydrogen from balance chemical equation.

                             Sn             :               H₂

                              1               :                2

                          0.57             :               2×0.57 = 1.14

Mass of hydrogen:

Mass = number of moles ×molar mass

Mass = 1.14 mol × 2 g/mol

Mass = 2.28 g
