This type of mixture is a heterogeneous mixture. It is any mixture that is not uniform. Heterogeneous mixtures always have more than one phase.It is made up of substances which stays physically separate with each other. Best example is a mixture of sand and sugar. If you get two samples from different points of the mixture and analyze it, you will see that the concentrations of the components are different and that the two solid phases never combine with each other.
Answer:
The answer is
<h2>150 mL</h2>
Explanation:
To convert the volume from cm³ to mL we use the conversion
1 cm³ = 1 mL
So from the question
if 1 cm³ = 1 mL
Then 150 cm³ = 150 mL
Hope this helps you
Given:
Ammonia
Hydrochloric acid
To find:
The amount excess of reactant left over in ammonia.
Solution:
Ammonia reacts rapidly with hydrochloric acid to form Ammonium Chloride
Equation for the above statement is derived as:
One gram per mole of ammonia
Similarly for 6.91g of
One gram per mole of hydrochloric acid
Similarly for 4.61g of
From the above information we can say that h c l is a limiting reactant.
Limiting reactant is an element that consumes lesser product in a chemical reaction.
Thus the amount of excess reactant is calculated by using the following formula
Amount of excess reactant left over in
Result:
Amount of excess reactant left over ammonia
It is important because it contributes to the movement of your knee
Answer:
Option 4 ) 1-butyne
Explanation:
In organic chemistry, you should use IUPAC convention in order to name an organic compound. First of all, you should identify the lenght of the organic chain, for this case, you have 5 C atoms, but in fact, you have a triple bond (which would be a substitute: ethynil-) as a substitute, so the main skeleton would have 4 C atoms (a butane)
Then, you start by numbering carbon N° 1 as the one that has the substitute (triple bound)-starting from the right, it would be the second C):
CH₃-CH₂-CH₂-C≡CH
Which will finally leads us to 1-butyne
