Answer:

Water is life, as the saying goes. We rely on water for our food, our health, our livelihoods, and for fun and leisure. But water can also take away life, and the absence of water can be even worse. Currently, 700 million people live in water-stressed areas. By 2025, this number is expected to grow 1.8 billion — about 25% of the world population.

As Number 6 on the UN’s Sustainable Development Goals, “Clean Water and Sanitation For All” is currently struggling. The UN suggests that, if we want to meet this goal by the deadline of 2030, we’ll need to double our current rate of progress to ensure that there’s universal access to safe and affordable drinking water, adequate sanitation and hygiene resources, improved water quality, and restored water-related ecosystems. Here are 5 ways that water affects our lives — and what we’re doing to help make them happen.

Explanation:

Many of the towns we live in were built near water sources. Oceans, rivers, streams and lakes make up some of our geographical boundaries. They also allow for water transportation and commerce and provide food and other resources.

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>Explanation:</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.

During oxidation of ethanol to ethanol, the ethanol formed was found to be contaminated with unconverted ethanol, describe how y

Dafna1 [17]

The process of how we would obtain ethanal free from ethanol is described in the explanations below.

In Chemistry, Ethanol undergoes oxidation in the presence of sodium dichromate plus sulphuric acid to yield ethanal and water.

The procedure for achieving this in the laboratory is as follows;

Step 1; Measure a quantity of a solution of sodium dichromate acidified in a dilute sulphuric acid and pour into a test tube.

Step 2; Add excess ethanol. This is because if we don't do so there will be plenty of oxidizing agent to carry out a second operation which changes the aldehyde to ethanoic acid. However, we need only the aldehyde.

Step 3; When the aldehyde ethanal begins to form which will be evident by the change in the colour of solution from orange to green, then the mixture should be distilled from the test tube and tbethe aldehyde collevted so that it doesn't undergo additional oxidation into ethanoic acid.
