What is heterogenous mixture

Chemistry
1 answer:
Kamila [148]3 years ago
7 0

Answer:

A heterogeneous mixture is simply any mixture that is not uniform in composition - it's a non-uniform mixture of smaller constituent parts. By contrast, a mixture that is uniform in composition is a homogeneous mixture.

Consider the half reactions below for a chemical reaction.
Butoxors [25]

Upper M g (s) plus 2 upper H right arrow upper M g (a q) plus upper H subscript 2 (g).

 Mg + 2H⁺      →      Mg²⁺ +    H₂

Explanation:

The net ionic equation is the sum of the oxidation half reactions.

The half-reactions are:

 Mg   →   Mg²⁺    +   2e⁻   Oxidation half reaction

  2H⁺    +     2e⁻    →       H₂    reduction half reaction

Combining the reactions gives:

Mg + 2H⁺    +     2e⁻   →       H₂ + Mg²⁺    +   2e⁻  

Since the electrons are balanced, they cancel out of the equation,

 This leaves behind;

   Mg + 2H⁺      →      Mg²⁺ +    H₂

Balance the following Equation:
lisabon 2012 [21]

Answer:

HCl is the limiting reactant. It will completely be consumed (1.37 moles)

Option D is correct

Explanation:

Step 1: Data given

Mass of Zinc (Zn) = 50.0 grams

Mass of Hydrogen chloride (HCl) = 50.0 grams

atomic mass Zn = 65.38 g/mol

Molar mass HCl = 36.46 g/mol

Step 2: The balanced equation

Zn + 2HCl → ZnCl2 + H2

Step 3: Calculate moles

Moles = mass / molar mass

Moles Zn = 50.0 grams / 65.38 g/mol

Moles Zn = 0.764 moles

Moles HCl = 50.0 grams / 36.46 g/mol

Moles HCl = 1.37 moles

Step 4: Calculate limiting reactant

For 1 mol Zn we need 2 moles HCl to produce 1 mol ZnCl2 and 1 mol H2

HCl is the limiting reactant. It will completely be consumed (1.37 moles)

Zn is in excess. There will react 1.37/2 = 0.685 moles

There will remain 0.764 -0.685 = 0.079 moles

How many moles of oxygen are produced when 2 mol of potassium chlorate (KClO3) decompose
ioda
Keep in mind that when two moles of potassium chlorate are decomposed, 3 moles of oxygen are produced.Think of  the coefficients: since the mole ratio is 2 to 3, it means that<span> 2 mol KClO3 will turn into 3 mol O2.

How does H2So4 break up to h+ &amp; hso4 - ?
Katena32 [7]
H2So4 is a strong acid and a strong electrolyte which means that when this dissociates in water, the dissociation process is complete. The first dissociation is 

H2 SO4 = H + HSO4- 

This can further release H+ and dissociate SO4- instead already
