Answers
Answer:
Insertions are mutations in which extra base pairs are inserted into a new place in the DNA. Deletions are mutations in which a section of DNA is lost, or deleted..Germline mutations occur in gametes. Somatic mutations occur in other body cells.Chromosomal alterations are mutations that change chromosome structure.Point mutations change a single nucleotide.Frameshift mutations are additions or deletions of nucleotides that cause a shift in the reading frame.Deletion is a type of mutation involving the loss of genetic material. It can be small, involving a single missing DNA base pair, or large, involving a piece of a chromosome.Base substitutions are the simplest type of gene-level mutation, and they involve the swapping of one nucleotide for another during DNA replication. For example, during replication, a thymine nucleotide might be inserted in place of a guanine nucleotide.Silent mutations are base substitutions that result in no change of the amino acid or amino acid functionality when the altered messenger RNA (mRNA) is translated. For example, if the codon AAA is altered to become AAG, the same amino acid – lysine – will be incorporated into the peptide chain..List the following gases in order of increasing average molecular velocity at 25 degrees Celcius: H20, He, HCI, BrF, and NO2 (I'm so confused... thank you in advance!!!)
Answers
Answer:
The picture is attached below!! Hope this helps!
The increasing order of average molecular velocity at 25 degrees Celcius is:
BrF< NO₂<HCl<H₂O<He
What is molecular velocity?It is defined whether it is normal speed, root mean square speed and most likely speed. It should be relative to the square to the square root of outright temperature.
The gas with the minimum molar mass will have the highest molecular speed.
Thus, Helium is having the lowest molar mass, therefore it will have the highest molecular velocity.

Atomic number is denoted by 'Z' which is the atomic number of an element and Z=13 for aluminium , the atomic number of aluminium.
It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
Aluminium has 13 protons and thus it's atomic number that is 'Z' is equal to 13.
Thus, 'Z' which is the atomic number of an element and Z=13 for aluminium ,the atomic number of aluminium.

11. Calculate the number of atoms in 2.00g of platinum.
Answers
Answer:
Explanation:
All you need to know is the atomic mass of platinum, and Avogadro's number.
2.00g Pt divided by atomic mass gives you the moles of platinum, and multiplying by avogadro's number (6.022 x 10^23) gives you the number of atoms.
Atomic mass of platinum can be found on any periodic table.
Hope this helped.
12.04 × 10²³ number of platinum atoms are present in 2 grams of platinum.
How we calculate no. of atoms?To calculate the no. of atoms in any substance, we have to multiply the no. of moles of that substance by the Avogadro's no.
Value of Avogadro's no. = 6.022 × 10²³
We can calculate the mole by using the below formula:
n = W / M, where,
n = no. of moles
W = given mass = 2.00g
M = molar mass or atomic mass = 195.09 g/mol
n = 2 / 195.08 = 0.0102 mol
Number of atoms in 2.00g of platinum = 2 × 6.022 × 10²³ = 12.04 × 10²³.
Hence, number of atoms that are present in 2.00g of platinum is 12.04 × 10²³.

The food flavor enhancer monosodium glutamate (MSG) has the composition 13.6% Na, 35.5% C, 4.8% H, 8.3% N and 37.8% O by mass. What is the empirical formula of MSG?
Answers
Answer:
C₅H₈NO₄Na
Explanation:
Step 1: Given data
Percentage by mass of Na in MSG: 13.6%Percentage by mass of C in MSG: 35.5%Percentage by mass of H in MSG: 4.8%Percentage by mass of N in MSG: 8.3%Percentage by mass of O in MSG: 37.8%Step 2: Divide each percentage by the atomic mass of the element
Na: 13.6/22.99 = 0.592
C: 35.5/12.01 = 2.96
H: 4.8/1.01 = 4.75
N: 8.3/14.00 = 0.592
O: 37.8/16.00 = 2.36
Step 3: Divide all the number by the smallest one, i.e. 0.592
Na: 0.592/0.592 = 1
C: 2.96/0.592 = 5
H: 4.75/0.592 ≈ 8
N: 0.592/0.592 = 1
O: 2.36/0.592 ≈ 4
The empirical formula of MSG is C₅H₈NO₄Na.
A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of pentane, ethanolamine, diethylamine, glycerol, and carbon tetrachloride. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density pentane 0.63gmL, ethanolamine 1.0gmL, diethylamine 0.71gmL, glycerol 1.3gmL, carbon tetrachloride 1.6gmL Next, the chemist measures the volume of the unknown liquid as 1737.cm3 and the mass of the unknown liquid as 1.23kg . Calculate the density of the liquid. Be sure your answer has the correct number of significant digits.
Answers
Answer:
0.71 g/mL
The liquid is diethylamine
Explanation:
Mass of the liquid = 1.23 kg of 1.23 * 10^3 g
Volume of the liquid = 1737.cm3
Let us remember that density is obtained as;
Density= mass/volume
Density= 1.23 * 10^3 g/1737cm^3
Density= 0.71 g/cm^3
Since we know that 1 mL=1 cm3 . So, 1 g/mL=1 g/cm3
So we can also write;
Density= 0.71 g/mL
The liquid is diethylamine
Classify each of the substances as an atomic element, molecular element, molecular compound, or ionic compound. Provide one sentence explanation for each. a. fluorine b. N2 O c. silver d. K2 O e. Fe2 O3 g
Answers
Answer and Explanation:
a. fluorine ⇒ atomic element
Fluorine (F) is a chemical element because it is a pure substance that cannot be decomposed into simpler substances.
b. N₂O ⇒ molecular compound
We can see that N₂O (nitrous oxide) is a molecule composed by two different atomic elements: nitrogen (N) and oxygen (O). Thus, it is a molecular compound.
c. silver ⇒ atomic element
Silver is a chemical element with the symbol Ag. It is a pure substance which cannot be decomposed into simpler substances.
d. K₂O ⇒ ionic compound
Potassium oxide (K₂O) is composed by a metallic element (potassium, K) and a non-metallic element (O). Thus, there is a difference in the electronegativity of the chemical elements, so the substance can dissociate into ions. In consequence, it is an ionic compound.
e. Fe₂O₃ ⇒ molecular compound (with ionic character)
Iron(III) oxide (Fe₂O₃) is composed by iron element (Fe), which is a metal, and oxygen element (O), which is a non-metal. Since it is a Metal- Non-Metal combination, it would be an ionic compound. The difference in electronegativity between Fe and O is not high (<2.0) in comparison with other ionic compounds, so Fe₂O₃ is considered as a polar covalent compound (it is between an ionic compound and a molecular compound).

5.88 dL = 0.588 litre
Explanation:
We need to find a conversion from 5.88 dL to liters.
We know that the conversion is as follows :
1 deciliter = 0.1 litre
To find 5.88 dL to liters, we use the unitary method. So,
5.88 dL= (0.1×5.88) litre
5.88 dL = 0.588 litre
So, there are 0.588 liters in 5.88 dL.

Answer:
Steam distillation is a separation process which purifies isolate temperature-sensitive materials, such as natural aromatic compounds. In steam distillation, dry steam is passed through the plant material. These vapours undergo condensation and collection in receivers.
distillation under pressure is used for the purification of those substance which get decompose on their boiling point. so , a suction pump (vaccum) is fitted with a beaker in order to lower it's pressure, due to which boiling pressure decreases. so that it can be distilled of before reaching to its boiling point.
Fractional distillation is a type of distillation which involves the separation of miscible liquids. The process involves repeated distillations and condensations and the mixture is usually separated into component parts. The separation happens when the mixture is heated at a certain temperature where fractions of the mixture start to vaporize.

This is the balanced reaction equation for the combustion of methane.
Explanation:
The Law of Conservation of Mass basically states that matter can neither be created nor destroyed. As such, we must be able to show this in our chemical reaction equations.
If you look at the equation above, you'll see an arrow that separates the reaction equation into two parts. This represents the direction of the reaction.
To the left of the arrow, we have our reactants.
To the right of the arrow, we have our products.
The quantity of each individual element in the left must equal the quantity of each individual element in the right.
So if you look below, you'll see the unbalanced equation, and I'll try to explain how to balance the reaction.

and

.
Our next step is to break these down into individual atoms.
We have:
1 C atom, 4 H atoms & 2 O atoms.
If you're confused by this, look to see the little number to the bottom right of each element, the subscript, and it tells you how many of each atom are in the molecule. Make sense?
Now we look to the other side of the equation.
Here we see our products are

Again, we break these down into individual atoms again.
We have:
1 C atom, 2 H atom, 3 O atom
