Two types of heterogeneous mixtures are suspensions and colloids.<br>true or false<br><br>​
scoray [572]
<h2>Answer:True</h2>

Explanation:

Heterogeneous mixture is a mixture with non-uniform composition.

The properties of the mixture like concentration may change for different parts of the mixture.

Colloids contain solute particles of size 2nm-500nm.The presence of these particles makes the mixture heterogeneous.

Suspensions contain solute particles of size 500nm-1000nm.These particles settle to the bottom of the mixture which makes the composition of the bottom different from the top.

So,colloids and suspensions are two types of heterogeneous mixtures.

If 3.5 grams of NaN3 decomposed, how many grams of N2 would be produced?
Wewaii [24]

Answer:

5.25 moles.

Explanation:

The decomposition reaction of NaN₃ is as follows :

2NaN_3(s)\rightarrow 2Na(s)+3N_2(g)

We need to find how many grams of N₂ produced in the process.

From the above balanced chemical reaction, we conclude that the ratio of moles of sodium azide and nitrogen gas are 2 : 3.

2 moles of sodium azide decomposes to give 3 moles of nitrogen gas. So,

3.5 moles of sodium azide decomposes to give \dfrac{3}{2}\times 3.5=5.25 moles of nitrogen gas.

Hence, the number of moles produced is 5.25 moles.

Alika [10]

Answer:

Look at the picture.

Explanation:

On stage one binding of a substrate occurs (and also the geometry of active site may change) and water comes to the site. On stage two the hydrolisis takes place and on stage 3 products deabsorb from the enzyme.
