Answer : b. mixture
<h3>Further explanation</h3>
Element and compound are included in pure substance where the composition is the same in each part
Elements are made up of 1 type of atom, while the compounds of 2 or more types of atoms
, both can be represented in the form of chemical symbols
A mixture is a combination of substances. The properties of a substance in the mixture component are unchanged
The mixture can be a homogeneous mixture or a heterogeneous mixture
- the homogeneous mixture if each part has the same composition
- the heterogeneous mixture if each part has a different composition
Solution including into Homogeneous mixture, while suspension into a heterogeneous mixture
So a term that could refer to heterogeneous matter : b. mixture
Answer:
moles, liter, concentration, and 6.0 mol/L
Explanation:
Since it is stated that nitrogen is the limiting reactant (sometimes called limiting reagent), you only have to worry about the amount of nitrogen since we know that there is excess silicon.
Since this is a stoichiometry question, the first thing to do is turn the mass of nitrogen gas into moles by dividing the mass of nitrogen gas by its molar mass. (14.33g)/(28g/mol)=0.5118mol nitrogen gas. Then you have to convert moles of nitrogen gas to moles of silicon nitride by using the fact that 2 moles of nitrogen gas turn into 1 mole of silicon nitride (i got that ratio from the chemical equation given). (0.511mol N₂)x(1mol Si₃N₄/2mol N₂)=0.2555mol Si₃N₄. Know you just need to find the mass of silicon nitride by multiplying the number of moles of silicon nitride by its molar mass. (0.2555mol)x(140g/mol)=35.85g
Therefore the amount of silicon nitride produced from this reaction 35.85g.

Explanation:
Answer:
The major product is 2-methyl-2-pentene [ CH₃-CH₂-CH=C(CH₃)₂ ] and a minor product 2-methyl-1-pentene [ CH₃-CH₂-CH₂-C(CH₃)=CH₂ ].
Explanation:
Dehydration reaction is a reaction in which a molecule loses a water molecule in the presence of a dehydrating agent like sulfuric acid (H₂SO₄).
<u>Dehydration reaction of 2-methyl-2-pentanol</u> gives a major product 2-methyl-2-pentene and a minor product 2-methyl-1-pentene.
CH₃-CH₂-CH₂-C(CH₃)₂-OH (2-methyl-2-pentanol)→ CH₃-CH₂-CH=C(CH₃)₂ (2-methyl-2-pentene, major) + CH₃-CH₂-CH₂-C(CH₃)=CH₂ (2-methyl-1-pentene, minor)
<u>Since more substituted alkene is more stable than the less substituted alkene. So, the trisubstituted alkene, 2-methyl-2-pentene is more stable than the disubstituted alkene, 2-methyl-1-pentene.</u>
<u>Therefore, the trisubstituted alkene, 2-methyl-2-pentene is the major product and the disubstituted alkene, 2-methyl-1-pentene is the minor product.</u>
