18. Reaction will occur.

19. Reaction Will occur.

20. Reaction will occur.

21. Reaction will occur.

22. Reaction won't occur.

23. Reaction will occur.

24. Reaction will occur.

25. Reaction won't occur.

<h3><u>Explanation</u>:</h3>

The reaction rate of the metals with water, steam, acid, or hydroxides or their inert behavior towards them are noted in the metal activity series.

It contains all the metals one after the other which and the upper metal can replace the lower metal from its salt.

Calcium can replace hydrogen from acid, so the reaction will occur in 18. The products formed are calcium phosphate and hydrogen gas.

Chlorine is more reactive than bromine. So it can replace bromine from its salt to from bromine gas and magnesium chloride.

Aluminium can replace iron from its salt. So it will form aluminium oxide and iron metal. This reaction is used to obtain iron from ores.

Zinc can replace hydrogen from acid. So the products will be zinc chloride and hydrogen gas.

Chromium cannot displace hydrogen form water. So the reaction won't occur.

Tin can replace hydrogen form acid. So the reaction will proceed.

Magnesium will replace platinum from its salt. So magnesium oxide and platinum will form.

Bismuth cannot replace hydrogen from acid. So the reaction won't proceed.

An increase in temperature affects the reaction rate by &gt;decreasing the velocities of particles that collide in the reaction.
Bond [772]

Answer:

increasing the number of molecules that have sufficient kinetic energy to react.

Explanation:

An increase in temperature affects the reaction rate by increasing the number of molecules that have sufficient kinetic energy to react.

or we say; temperature increase, leads to an increase in the amount of collisions between molecules.

topjm [15]

Answer:

  • <u><em>1.7 × 10³ kg of ore.</em></u>

Explanation:

Call X the amount of aluminum ore mined to produce 1.0 × 10³ kg the aluminum metal.

Then, taking into account the yield of the reaction (82 % = 0.82) and the percent of aluminun in the ore (71% = 0.71), you can write the following equation:

  •  X         ×          71%                ×       82%     =     1.0 × 10³ kg

         ↑                      ↑                              ↑                     ↑

(mass of ore)    (% of Al in the ore)        (yield)        ( Al metal to obtain)

You must just simplify, solve and compute:

  • 0.71 × 0.82 × X = 1,000
  • X = 1,000 / (0.71 × 0.82) = 1,000 / 0.5822 = 1,717.6 Kg

Round to two significant figures; 1,700 kg = 1.7 × 10³ kg of ore ← answer.
