Bumek [7]4 years ago
6 0

The  element  that has  been  oxidized   is Al  (  Answer  A)


Explanation

 if  the oxidation number of an element is greater in the product side than the reactant  side  then the element   has lost  the electrons . This mean  that  the element  has been oxidized.

Al  is  oxidized  because  it move  from  oxidation  state  Zero(0)  in reactant side  to  oxidation state 3⁺  in product  side.

This  implies  that  Al  loses  3  electrons.

A small hole in the wing of a space shuttle requires a 20.7-cm² patch.
cricket20 [7]

The Patch's area of the space shuttle in km² is 2.07 × 10⁻⁹ km²

Given, that a space shuttle requires a 20.7 cm² patch

We have to convert the patch's area from cm² into km².

Unit conversion is a method in which we multiply or divide with a particular numerical factor and then finally round off to the nearest significant digits.

Patch area of the space shuttle is 20.7 cm²

1 cm = 0.00001 km

or, 1 cm² = (0.00001 km)²

or,  1 cm² = 10⁻¹⁰km²

20.7 cm² = 20.7 ×  10⁻¹⁰km²

20.7 cm² = 2.07 × 10⁻⁹ km²

The patch area in square kilometers is 2.07 × 10⁻⁹ km²

lana [24]

Answer:

See explanation

Explanation:

Coal is primarily used for electricity generation. The burning of coal leads to emission of gases such as oxides of carbon, oxides of sulphur, oxides of nitrogen and water vapour. All these go straight into the atmosphere.

Petroleum is primarily used as transportation fuels. The burning of petroleum oils mostly leads to the emission of oxides of carbon and sulphur together with water vapour into the atmosphere.

Displacement is the slope of a velocity vs. time graph<br><br> A. True<br><br> B. False
mezya [45]

Answer:

The given statement is false.

Explanation:

Displacement is a vector quantity which represent shortest distance form initial position to final position.

Velocity of an object is defined as ratio of displacement of object to that of the time taken by object to move from its initial position to final position.

In displacement vs time graph the slope of the graph represent the velocity. Whereas slope of velocity vs time graph gives acceleration.
