Answer:
Explanation:
We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.
MM: 74.12 184.24
CH₃CH₂CH₂CH₂OH + (C₆H₅)₂CHOH ⟶ Product
m/g: 1.30
ρ/g·mL⁻¹: 0.8098
1. Moles of benzhydrol (BH)
2. Moles of butan-1-ol (BuOH)
The molar ratio is 1 mmol BuOH:1 mmol BH.
3. Mass of BuOH
4. Volume of BuOH
Answer:
In given structure of substituted cyclohexane select the "Bromine" atom as the answer.
Explanation:
1,3-Diaxial Interactions:
As cleared from name, this type of interactions are found in cyclic alkanes in which one group present at position 1 (assumed number) experiences steric hindrance due to another group present at position 3.
Also, it is necessary that both the groups must be occupying either axial or equatorial positions respectively. For example, in given structure the methyl group at position 1 is at axial position and another bulky group which should interact with this methyl group must occupy axial position at carbon 3 next to carbon 1. Hence, as shown in figure, the Bromine atom is present at third carbon and is at axial position too.
In attached picture, the green lines indicate steric interactions between Methyl group and Bromine atoms which are involved in steric interactions in 1,3-diaxial fashion.
Answer:
25.99mL is the volume internal volume of the flask
Explanation:
<em>To complete the question:</em>
<em>The temperature of the water was measured to be 21ºC. Use this data to find the internal volume of the stoppered flask</em>
<em />
The flask was filled with water, that means the internal volume of the flask is equal to the volume that the water occupies.
To find the volume of the water you need to find the mass and by the use of density of water at 21ºC (0.997992g/mL), you can find the volume of the flask, thus:
Mass water = Mass filled flask - Mass of clean flask
Mass water = 60.167g - 34.232g
Mass water = 25.935g of water.
To convert this mass to volume:
25.935g × (1mL / 0.997992g) =
<h3>25.99mL is the volume internal volume of the flask</h3>
Mineral resource : It is the source of any material in earth's crust. The source from which there is opportunity of extraction of the material.
Mineral reserve : The mineral resource from which a material can be extracted by means of economic techniques. The ores of metals are generally considered to be mineral reserve.
