Answer:
The answer for 2-hexene is that the structure should have 6 carbon with a double bond beginning on the 2nd carbon atom.
The answer for 1-pentyne is that the structure should have 5 carbon with triple bond beginning on the 1st carbon atom.
Explanation:
<u>2-Hexene</u>
The structural formula for 2-hexene will have 6 carbons because the nomenclature has a -hex prefix, which stands for 6 carbons.
The -ene suffix of the nomenclature means that the organic compound is an alkene. Alkenes are hydrocarbons that contain double covalent bond and have the suffix -ene.
The double bond is on the 2 carbon atom because the nomenclature states that the double bond will be on the 2 carbon atom.
<u>1-Pentyne</u>
The structure will have 5 carbons since the -pent prefix means 5 carbons.
The structure has a triple bond because the -yne suffix means that the structure is an alkyne. An alkyne is a hydrocarbon with triple covalent bonds.
Also, the position of the triple bond is known because the nomenclature of the alkyne states that the triple bond is on the 1st carbon.
The answer is 207.2 grams.
Answer: the moon passes through the earth's shadow
Explanation:
In this case the earth's shadow blocks the sun's light which normally is reflected off the moon's surface. So since the sunlight is blocked by the earth we call this a lunar eclipse
In group theory, a branch of mathematics, the term order is used in two unrelated senses:
<span><span>The order of a group is its cardinality, i.e., the number of elements in its set. Also, the order, sometimes period, of an element a of a group is the smallest positive integer m such that <span>am = e</span> (where e denotes the identity element of the group, and am denotes the product of m copies of a). If no such m exists, a is said to have infinite order.</span><span>The ordering relation of a partially or totally ordered group.</span></span>
This article is about the first sense of order.
The order of a group G is denoted by ord(G) or | G | and the order of an element a is denoted by ord(a) or | a |.
The density of the unknown metal, given the data is 1.67 g/mL
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
With the above formula, we can determine the density of the unknown metal. Details below:
<h3>How to determine the density </h3>
- Mass of unknown metal = 20 - 0 = 20 g
- Volume of unknown metal = 12 - 0 = 12 mL
- Density of unknown metal =?
Density = mass / volume
Density of unknown metal = 20 / 12
Density of unknown metal = 1.67 g/mL
Thus, the density of unknown metal is 1.67 g/mL
