Explain what happens during cytokinesis. This needs to be detailed.
Answer:
During cytokinesis, which is a physical process of cell division, the cells divide the cytoplasm of a parent cell into two daughter cells. The ring on the outside of the cell which is also known as a contractile ring, shrinks at the equator of the cell which causes pinching, and the plasma membrane goes inward. After all that happens there’s something called a cleavage furrow which is the formation of a dip between the two cells while they are splitting.

how many liters is 1.9 mol of Cl2 at STP?
Answer:
V = 42.6 L
Explanation:
Given data:
Number of moles of Cl₂ = 1.9 mol
Temperature and pressure = standard
Volume occupy = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
By putting values,
1 atm × V = 1.9 mol ×0.0821 atm.L /mol.K × 273.15 k
V = 42.6 atm.L / 1 atm
V = 42.6 L

16) Which scientist and model/experiment unintentionally discovered the electron?
A. Rutherford - Gold Foil Experiment/Nuclear
B. Thompson - Cathode Ray Tube/Plum Pudding
C. Bohr Model - Planetary Model
D. Schrodinger - Electron Cloud Model
Answer:
B. Thompson - Cathode Ray Tube/Plum Pudding
Explanation:
The scientist and the model/experiment that unintentionally discovered the electron was the Thompson's - Cathode Ray Tube/Plum Pudding.
Experiments on the discharge tubes was performed by J.J Thomson in 1897 and this led to the discovery of the electron as a subatomic particle.
The properties of the cathode rays were studied and presented by Thomson in his work at that time.
He observed that cathode rays move in a straight line normal to the cathode and can cast the shadow of an object placed along their path. They possess kinetic energy and so can cause the motion of a mechanical paddle wheel placed along their path They attract positive charges and repel negative charges.how many moles are in 3 grams of Hydrogen gas.
Answer:
Number of moles = 1.5 mol
Explanation:
Given data:
Number of moles = ?
Mass in gram = 3 g
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of hydrogen gas = 2.02 g/mol
By putting values,
Number of moles = 3 g / 2.02 g/mol
Number of moles = 1.5 mol
A sample of iron (Fe) contains 2.10 x 1023 atoms. The mass of this sample of iron in grams is... (1 mol of atoms = 6.022 x 1023 atoms = 55.8 grams)
a.) 19.59
b.) 0.3499
c.) 1.17 x 10259
d.) 6.24 x 10-39
Answer:
Mass = 19.53 g
Explanation:
Given data:
Number of atoms of iron = 2.10 ×10²³ atoms
Mass of iron = ?
Solution:
The number 6.022 ×10²³ is called Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
1 mole contain 6.022 ×10²³ atoms
2.10 × 10²³ atoms × 1 mol / 6.022 ×10²³ atoms
0.35 mol
Mass of iron atoms:
Mass = Number of moles × molar mass
Mass = 0.35 mol × 55.8 g/mol
Mass = 19.53 g

#3 What size container would 67.3mol CO2 need at STP?
Answer:
The volume of the container would be 1507 L
Explanation:
These question can be solved in two different ways:
Let's do the short road.
We know that 1 mol of anything at STP conditions occupies 22.4 L
By a rule of three:
1 mol contains 22.4L at STP
Then, 67.3 mol of gas would be contained in (67.3 . 22.4) /1 = 1507.5 L
We assume CO₂ as an Ideal Gas, so we can apply P . V = n . R . T
At STP, T is 273.15K and P = 1 atm. We replace:
1 atm . V = 67.3 mol . 0.082 . 273.15K
V = (67.3 mol . 0.082 . 273.15K) / 1 atm → 1507 L
John is running the 1600-meter race at his school's track meet. He runs the full 1600
meters in 6.5 minutes. What is John's average speed in meters/second rounded to
the nearest tenth?
Answer:
4.1m/s
Explanation:
6.5min=6×60+30=390s
v=1600÷390=4.1m/s
John is running the 1600-meter race at his school's track meet. He runs the full 1600 meters in 6.5 minutes, then his average speed of John would be 4.1 meters per second.
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.
As given in the problem, John is running the 1600-meter race at his school's track meet. He runs the full 1600 meters in 6.5 minutes,
The distance covered by the John = 1600 meters
The time taken by the John = 6.5 minutes
=6.5×60
=390 seconds
The speed of the John = 1600/390
= 4.1 meters per second
Thus,the speed of the John n meters/second rounded to the nearest tenth would be 4.1 meters per second.

b)4, 6, 1, 2
c)4, 7, 2, 4
d)2, 3, 1, 2
Answer: c)4, 7, 2, 4
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken.
In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.
The balanced chemical equation will be :
[tex]4FeS+7O_2\rightarrow 2Fe_2O_3+4SO_2[/tex]
The coefficients when the chemical equation below is balanced are 4, 7, 2, 4

A sample of SO2 gas has a volume of 2.36 L at a temperature of 27°C. At what temperature will the gas have a volume of 1.45 L?
Answer:
New temperature T2 = 16.59°C Approx
Explanation:
Given:
Old volume V1 = 2.36 L
Old temperature T1 = 27°C
New volume V2 = 1.45 L
Find:
New temperature T2
Computation:
Using Charles's Law;
V1T2 = V2T1
(2.36)(T2) = (1.45)(27)
New temperature T2 = 16.59°C Approx

the ultrasound wave 5 seconds to travel from the device to the sunken submarine and back
again. How far below the surface is the sunken submarine? (Be sure to use the proper units of
measure) * 5
Answer:
3750 m
Explanation:
We must first know the speed of sound in water in order to solve this problem.
So, speed of sound in water = 1500 meters per second
Now time taken = 5 seconds
Given that;
v = 2x/t
where x is the distance below;
vt = 2x
x = vt/2
x = 1500 * 5/2
x = 3750 m
In the formula for an ionic compound, the negative ion is
always written first.
TRUE
FALSE
Answer: False
Explanation: In the written form of an ionic compound, the positively charged cation always comes before the negatively charged anion. For instance, the written name for is calcium chloride because the compound has calcium () cations and chloride () anions.
In the formula for an ionic compound, the negative ion is always written first. This statement is false.
What do you mean by an ionic compound ?The term an ionic compound is defined as a chemical compound composed of ions carried together by electrostatic forces termed ionic bonding.
The compound is neutral charge, but made up of positively charged ions called cations and negatively charged ions called anions.
The compounds that affect a metal binding with either a non-metal or a semi-metal will display ionic bonding.
In the formula an ionic compound, the positively charged cation always comes before the negatively charged anion.
For example, the written name for is calcium chloride because the compound has calcium (+) cations and chloride (-) anions.
Thus, In the formula for an ionic compound, the positive ion is always written first.

Answer: H
H- C- H
H
Explanation:
Lewis structures are the structures which represent the valence electrons of the element around the chemical symbol of the element.
Carbon is an element which belong to group 14. Atomic number of carbon is 6 that means it contains 6 electrons, Thus the electronic configuration is represented as: [tex]1s^22s^22p^2[/tex] . Thus the valence electrons are 4.
Hydrogen is an element which belong to group 1. Atomic number of hydrogen is 1 that means it contains 1 electron, Thus the electronic configuration is represented as: [tex]1s^1[/tex] . Thus the valence electron are 1.
The four valence electrons of carbon are shared with one valence electron of hydrogen each.
How many moles of Al2O3 are formed from the reaction of 6.38 mol O2 and 9.15 mol Al?
With Explanation please !
Moles of Al₂O₃ formed : 1.42
Further explanationGiven
6.33 mol O₂
9.15 mol Al
Required
moles of Al₂O₃
Solution
Reaction
4Al + 3O₂ ⇒ 2Al₂O₃
Find limiting reactant (mol : coefficient) :
Al = 9.15 : 4 = 2.29
O = 6.38 : 3 = 2.13
O₂ as a limiting reactant(smaller ratio)
Mol Al₂O₃ based on mol O₂ as a limiting reactant
From equation, mol ratio Al : Al₂O₃ = 4 : 2, so mol Al₂O₃ :
= 2/3 x mol O₂
= 2/3 x 2.13
= 1.42
