A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions .

It is a homogeneous mixture since the components of tap water are blended so that it looks like a single substance, since you only see water and nothing else.

(Heterogenous mixtures are mixtures in which the separate components that make up the substance are visible .)

It is homogeneous too ...

Answer:

1. A mixture is a material made up of two or more different substances which are physically combined.A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspension and colloids.

2. Tap water is a homogeneous mixture, not heterogeneous. This is because tap water has dissolved minerals inside it, but they are equally distributed throughout the water.

3. 70% rubbing alcohol means that 70% of the molecules in the rubbing alcohol is actually alcohol. The other 30% is water. As I have stated at the start the answer, although alcohol is technically pure, rubbing alcohol is not purely made of alcohol.

Balance the redox reaction in alkaline medium & identify the oxidizing & reducing agents
Darya [45]

The balanced redox equation of the reaction is given below:

  • I⁻ + 2 MnO₄ + H₂O → IO₃⁻ + 2 MnO₂ + 2 OH⁻

The oxidizing agent is MnO₄ while the reducing agent is I⁻.

<h3>What are redox equations?</h3>

Redox equations are equations in which oxidation and reduction reactions occur together.

Redox reactions can take place in alkaline or acidic mediums.

The balanced redox equation of the reaction is given below:

  • I⁻ + 2 MnO₄ + H₂O → IO₃⁻ + 2 MnO₂ + 2 OH⁻

The oxidizing agent is MnO₄ while the reducing agent is I⁻

In conclusion, a balanced redox equation is one in which the atoms and the change in oxidation state is equal on both sides of the reaction.

How many moles of 18L of NH3 at 30 celcius and 912 mmHg? how many grams?
babymother [125]
Answer is: mass of ammonia is 14.76 grams and amount is 0.87 moles.<span>
V(NH</span>₃<span>) = 18 L.
T = 30°C = 303.15 K.
p = 912 mmHg ÷ 760 mmHg/atm= 1.2 atm.
R = 0.08206 L·atm/mol·K.
Ideal gas law: p·V = n·R·T.
n</span> = p·V / R·T.
n(NH₃) = 1.2 atm ·18 L / 0.08206 L·atm/mol·K · 303.15 K.
n(NH₃) = 0.87 mol.
m(NH₃) = n(NH₃) · M(NH₃).
m(NH₃) = 0.87 mol · 17 g/mol.
m(NH₃) = 14.76 g.<span>

</span>
