state four difference between the series and parallel connection?
Answer:
1- The components in a series circuit are arranged in a single path from one end of supply to another end. However, the multiple components in a parallel circuit are arranged in multiple paths where the two end terminals of the battery.
2- In the series circuit, different voltage exists across each component in the circuit. Whereas in the parallel circuit, the same voltage exists across the multiple components in the circuit.
3- The equivalent resistance in case of a series circuit is always more than the highest value of resistance in the series connection. While the equivalent resistance in the parallel circuit is always less than any of the individual resistances in parallel combination.
4- A fault in one of the components of the series circuit causes hindrance in the operation of a complete circuit. As against fault in a single component in a parallel network do not hinder the functioning of another part of the circuit.
The detection of a fault in case of a series circuit is difficult, but it is quite easy in parallel circuits.

a single cell undergoes mitosis every five minutes how many cells will result from this cell in 20 minutes
Answer:
= 16 cells
Explanation:
Mitosis is the stage of cell division in nonsexual cells of eukaryotic organisms (that is, cells that have a nucleus). It takes place in several phases, begins after DNA duplication and ends with the separation of the two daughter cells.
It is a fundamental mechanism that occurs for the first time in the hours following fertilization.
After duplication of the genetic material, during interphase, it condenses and groups to form chromosomes with two genetically identical chromatids: this is the prophase. The nuclear membrane then dislocates, and the centromeres of the chromosomes (the area where the two chromatids of the same chromosome overlap) bind to the microtubules via the kinetochores. Gradually, all the chromosomes are sequestered at the equator of the cell: this is the metaphase.
Then, during anaphase, the chromosomes will split into two chromatids, each of which is pulled towards a pole of the cell. Thus, at each top of the cell, there is a copy of each chromosome. During telophase, the nuclear envelope will begin to reform around the set of chromosomes as the DNA gradually decondensed. The plasma membrane invaginates equatorially under the action of a ring of myosin and actin. Increasingly narrow, the bridge between the cells eventually breaks, and two cells are formed as a result of cytodieresis. Each of them can resume their growth.
Now; having understood what Mitosis is all about.
When a single cell undergoes mitosis every 5 minutes; we have the formation of two daughter cells.
Then in 20 minutes; we will have:
= [tex]2^{20/5}[/tex]
= [tex]2^4[/tex]
= 16 cells

1 mole of a gas occupies 22.4 L at ________
Answer: At STP, one mole (6.02 × 1023 representative particles) of any gas occupies a volume of 22.4 L (Figure below). A mole of any gas occupies 22.4 L at standard temperature and pressure (0°C and 1 atm).
Explanation:
That the answer
1 mole of a gas occupies 22.4 L at (0°C and 1 atm). It is the standard temperature and pressure.
What is Avogadro's hypothesis?Avogadro's hypothesis says that all gases have an equal number of particles at the same temperature and pressure.
The empty space between the particles makes up the majority of a gas's overall volume.
Due to this, the size of the particles themselves is nearly insignificant.
The volume of one mole of a gas at standard temperature and pressure is known as the molar volume.
Thus, the correct option is 0°C and 1 atm.

Similarities and Differences in the order in which electrons are filled in s and d subshells.
Answer: Each orbital is found on different areas of the periodic table. The s sublevels are found on the first(left) and last(right) columns of the period table which hold a maximum of two electrons since it only has one orbital. First, each orbital can hold a maximum of two electrons. The other three sublevels: p, d, and f respectively have more orbitals, which is why they can hold more electrons. These sublevels of orbitals stand for sharp(s), principle(p), diffuse(d), and fundamental(f) (these are simply the categories of orbitals).
p has 3 orbitals so it can hold 6 electrons max. d has 5 orbitals so it can hold 10 electrons max. f has 7 orbitals so It can hold 14 electrons max.
Here is a picture of these orbital groups so you can understand a little better:
Calculate the mass percent of sulfuric acid in a solid sample given a 0.8390g sample of that solid required 32.22 mL of 0.2012 M NaOH for neutralization.
A) 62.11
B) 2.64
C) 37.89
D) 75.78
E) 1.27
Please give an answer and an explanation, thanks!
Answer
C
Explanation:
i remember learning this
Mass percentage does not have any unit as numerator and denominator contains the same unit. The percentage of sulfuric acid in solid sample is 38.07%.
What is percentage by mass?Mass percentage represents the the percentage of each element that is making a particular compound.
Mathematically,
Percentage of mass = (component’s mass ÷ total mass) x 100%
[tex]\rm 2 NaOH aq + H _{2} SO _{4} aq → Na _{2}SO _{4}aq + 2 H _{2} O[/tex]
Volume of NaOH solution = 32.22 mL = 0.03222 L
Concentration or molarity of the NaOH solution = 0.2012 M
Moles of NaOH : 0.03222×0.2012=0.006444mol
2 moles of sodium hydroxide reacts with 1 mole of sulfuric acid.
0.006444mol of sodium hydroxide reacts with =0.006444÷2=0.003222mol of sulfuric acid.
Mass of sulfuric acid neutralized = 0.003222 moles × 98.08 g/mol =0.31601376g
Percentage of sulfuric acid in solid sample= (0.31601376g÷0.8390g)×100=38.07%
Thus the percentage of sulfuric acid in solid sample is 38.07%.

Which element has 5 protons 5 neutrons and 5 electrons
Elements are the smallest unit of the atom and cannot be divided. An element having 5 electrons, protons, and neutrons is a boron.
What are subatomic particles?Subatomic particles are the constituents of atoms that have mass and charge. They are the components that make the element unique and give the atomic number and the mass.
The electron is a negatively charged particle and protons are positive particles that along with neutral neutron give the atomic mass. An element with 5 sub atomic particles is called a boron.
Therefore, the element is boron.
