Die........ no jk it turns the sugar to starch
A solution is a homogenous mixture meaning it has a uniform appearance throughout. (example: salt water)
heterogeneous mixture is visibly composed of different things. (example: chicken noodle soup)
Answer:
8.9L is the volume of the gas that must be dissolved.
Explanation:
For a weak base, we can find [(CH₃)₃N] using the equation:
Kb = [OH⁻] [[(CH₃)₃NH⁺] / [(CH₃)₃N]
As [OH⁻] = [[(CH₃)₃NH⁺] and [OH⁻] = 10^-pOH = 3.16x10⁻³M:
6.3x10⁻⁵ = [3.16x10⁻³M][3.16x10⁻³M] / [(CH₃)₃N]
[(CH₃)₃N] = 0.1587M
As the volume is 2.5L, moles are:
2.5L * (0.1587mol / L) = 0.3968moles
Using:
PV = nRT
We can solve for volume of the gas as follows:
P = 1atm at STP; n = 0.3968moles; R = 0.082atmL/molK; T = 273.15K at STP
V = 0.3968mol*0.082atmL/molK*273.15K/1atm
V = 8.9L is the volume of the gas that must be dissolved.
1. Structure of an atom:-
The basic structure of an atom includes a tiny, relatively massive nucleus, containing at least one proton and usually one or more neutrons.Outside of the nucleus are energy levels (also called shells), which contain one or more electrons.
Properties of an atom:-
The neutrons have the greatest mass and have no charge. The protons have slightly less mass than the neutrons and are positively charged. The electrons have almost no mass and are negatively charged. The chemical properties of the atom are determined by the number of protons, in fact, by number and arrangement of electrons.
2. Elements and their chemical symbols :-
1) Sodium - Na
2) Carbon - C
3) Magnesium - Mg
4) Aluminium - Al
5) Silicon - Si
6) Chlorine - Cl
7) Potassium - K
8) Calcium - Ca
9) Copper - Cu
10) Iron - Fe
3. ionic bond
Covalent bond
Metallic bond
4. pH scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower pH values than basic or alkaline solutions
5. There are four natural states of matter: Solids, liquids, gases and plasma.
6. Law of conservation of mass :
The 'law of conservation of mass' says that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. The mass of the products in a chemical reaction must equal the mass of the reactants.
Law of conservation of energy :-
According to the law of conservation of energy, energy can only be transformed from one form to another. It can neither be created nor destroyed. The total energy before and after the transformation always remains constant.
Answer:
Explanation:
Answer:
<u>cis-</u>isomer reacts faster
Explanation:
The missing diagrams in the question are attached in the first image below and the isomers that react faster are shown in the second image attached.
The <u>cis-</u>isomer quickly follows E2 reaction due to the fact that it is locked in a chair conformation whereby chlorine dominates an <u>axial </u>position, as displayed in drawing <u>C </u>as well as the leaving group <u>Cl</u> which is antiperiplanar to a beta proton.
Due to the bulkiness of tert-butyl, the<u> trans-</u>isomer is Basically trapped in a chair configuration, with chlorine occupying an <u>equatorial</u> position as displayed in drawing <u>A</u> below, thus leaving the group isn't antiperiplanar to a beta proton.
Tert butyl favors an equatorial position due to its bulkiness. This makes the Cl to assume an axial position in an isomer
The difference:
From the second image attached below, in the first diagram(1):
Suppose H is antiperiplanar, C-H bond electrons reach antibonding orbitals of C-Cl, assisting in the breakdown of the C-Cl bond and therefore speeding up the process.
From the second diagram(2) in the second image:
Unless Cl is in the axial position would it have β-hydrogen in the antiperiplanar position. Because tert-butyl prefers equatorial location, the Cl occupies equatorial position in the trans isomer.
As a result, the reaction is slower and there is no β-hydrogen antiperiplanar to Cl.
