Liono4ka [1.6K]3 years ago
3 0

Answer:

Magnetivity and melting point.

Explanation:

Aluminum, steel and tin cans can be separated by two step process of magnetisation and melting point, because the three cans have different magnetic properties.

Steel attract to magnet easily because of it's has magnetic properties and these separate steel from aluminum.

Neither steel and aluminum melted at 300°C but Tin melt at that temperature.

In which reaction do four total molecules of reactants produce two total molecules of products?
Pachacha [2.7K]

Answer:

option D = N₂ + 3H₂   →   2NH₃

Explanation:

The reaction in which the nitrogen and hydrogen are reacted to form the ammonia is true.

  N₂ + 3H₂   →   2NH₃

In this reaction we can see that one molecules of nitrogen react with three molecules of hydrogen and form two molecules of ammonia.

while the other options are in correct because,

2SO₂  +  O₂    →   2SO₃

In this reaction two molecules of SO₂ react with one molecule of oxygen and form two molecules of SO₃.

2H₂S  +  3O₂   →     2SO₂ + 2H₂O

In this reaction two molecules of H₂S react with three molecules of oxygen and produced four molecules of product.

SnO₂ +  2H₂   →  Sn + 2H₂O

This is also incorrect because three molecules of reactant form three molecules of product.

What is the density of a substance that contains 850 milligrams for every mL? Express your answer in grams per cm³.
Temka [501]

The density  of substance that contain  850 milligrams  for every  Ml  is  

0.85 g/Cm³


    calculation

<em>  </em><em>step 1:</em><em>convert   850 Mg  to g</em>

<em>that is 1  mg=0.001 g</em>

<em>         850 mg =? g</em>

<em>= (850 mg   x  0.001  g)/ 1 mg=0.85 g</em>


<em>step 2:  convert  Ml  to  Cm³</em>

<em>            that is 1  Ml =  1 cm³</em>


<em>therefore density  =</em><em> 0.85 g/Cm³</em>
