Answer: 56.2 g of Aluminium is needed to react fully with 100 grams of sulphur.

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} S=\frac{100g}{32g/mol}=3.125moles

The balanced chemical equation is:

2Al+3S\rightarrow Al_2S_3  

According to stoichiometry :

3 moles of S require = 2 moles of Al

Thus 3.125 moles of S will require=\frac{2}{3}\times 3.125=2.08moles  of Al  

Mass of Al=moles\times {\text {Molar mass}}=2.08moles\times 27g/mol=56.2g

Thus 56.2 g of Aluminium is needed to react fully with 100 grams of sulphur.

Explain why powdered milk and water do not<br>form a homogeneous mixture​
lara31 [8.8K]

Answer:

Milk, which when not subjected to temperature, is a homogeneous mixture. This is because- the various components of pure milk, which are the nutrients present in it, don't form separate layers in it and hence can’t be separated by any physical method.

But when milk is subjected to external factors, such as temperature, the milk fat no more remains dissolved in the milk but instead can be seen as a layer on the top-either as a white solid layer which is called as the cream or as yellow droplets. The two layers can be separated by physical means and hence making milk a heterogeneous mixture.

So the conclusion is that milk is a homogeneous mixture by default.

b) H20+NaCl= NaOH + O+ Cl

c) Cl2+ Ca(OH)2=CaOCl2+CaCl2 +HCL

Explanation:

electricity splits up the molecules for water and hydrogen displaces chlorine because its is more reactive.

Draw to scale size a model of the earth's crust in mine-craft like the pictures below take pictures of different angles​ and vid
Nezavi [6.7K]

To build a model of the Earth, several physical aspects must be taken into account, such as the composition of its interior and its external appearance.

<h3>How to draw a scale model of the Earth?</h3>

To draw a scale model of the Earth we must take into account different aspects so that it has the most similar appearance to our planet.

To draw the Earth we must know that the shape of our planet is not a sphere but rather a geoid that has irregularities and is flattened.

Additionally, we must take into account the physical characteristics such as:

  • The colors of the sea and the oceans.
  • The different mountain ranges.
  • The polar ice caps.
  • The shapes of the continents.
  • The inner layers.
