Answer:

Metals which react with steam form the solid metal oxide and hydrogen gas.

In general, the more reactive the metal, the more rapid the reaction. Aluminium is unusual, because it is a reactive metal that does not react with water. Its surface forms a protective layer of aluminium oxide that keeps water away from the metal below.

The apparatus used to react a metal with steam and collect the gas produced is shown below.

Answer:

This is because some metals like aluminium, zinc, iron do not react with hot/cold water ; they react only with steam to form a metal oxide and hydrogen.

Elis [28]

Answer:

37°

Step-by-step explanation:

We have been given the diagram of the triangle;

To find the angle I;

We need to apply one of the geometry laws,

The sum of adjacent internal angles of a triangle gives the external angle;

So;

I + 115 = 152

Solve for I;

I = 152 - 115 = 37°

Which expression can be used to show a 40% discount on an item costing $74 plus 7% tax?

kakasveta [241]

The final price inculding tax after discount is $ 47 and expression used is:

Required expression = price of item - discount price + tax on item

<h3>Solution:</h3>

Given that 40% discount on an item costing $74 plus 7% tax

So cost of item = $ 74

Tax = 7 %

Discount = 40 %

The expression which can be used to find price after discount including tax is:

Required expression = price of item - discount price + tax on item

Let us first find the price after discount

Price after discount = cost of item - 40 % of cost of item

Price after discount = 74 - 40 % of 74

$= 74 - \frac{40}{100} \times 74\\\\= 74 - 29.6 = 44.4$

Thus the price after discount is approximately $ 44

Now tax is 7 % which means 7 % of $ 44

Price including tax = 44 + 7 % of 44

Price including tax = $44 + \frac{7}{100} \times 44 = 44 + 3.08 = 47.08$

Thus the final price inculding tax after discount is $ 47
