What is a cell ?The smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. The cell membrane, the nucleus, and the cytoplasm are the three primary components of a cell. The chemicals that enter and leave the cell are governed by the cell membrane, which encloses the cell.
The cell membrane, the nucleus, and the cytoplasm are the three components that make up a cell. Intricate arrangements of microscopic fibers and hundreds or even thousands of tiny, unique structures known as organelles can be found in the cytoplasm.
The system's inputs are the signals or data it receives, and its outputs are the signals or data it sends. As part of an activity, the phrase can also be employed; for example, to "perform I/O" is to carry out an input or output operation.
Thus, The input of cell systems share are glucose and oxygen. The output of cell systems share are carbon dioxide, energy and water.

How many molecules are in 10 moles of H2
Answers
10(6.02*10^23)= 6.02*10^24
The number of molecules in one mole of hydrogen gas is 6.02 × 10²³ . The number of molecules in 10 moles of hydrogen gas is then 6.022 ×10²⁴.
What is one mole?Any substance that contains 6.022 × 10²³ number of atoms is called ne mole of that substance. This number is called Avogadro number. Hence, one mole of every elements contains Avogadro number of atoms.
Hydrogen is the first element in periodic table. It is an alkali metal. The number of molecules in one mole of H₂ is equal to Avogadro number. Mass of a molecule with one mole of amount is called its molecular mass.
Number of molecules of H₂ in one mole = 6.02 × 10²³
Then number of molecules in 10 moles is Avogadro number times the number of moles.
= 10 × 6.022 × 10²³ = 6.022 ×10²⁴ molecules
Therefore, 10 moles of H₂ contains 6.022 ×10²⁴molecules..

Answer:
Not balanced. There are different number of atoms on each side of equation.
Explanation:
Given balanced chemical equation:
Chemical equation:
3C₂H₄ + 3O₂ → 4CO₂ + 6H₂O
The equation is not balanced because umber of moles of C, H and O are not balanced. It consist of six moles of C, 12 moles of H and six moles of oxygen on left side of equation while on right side there are 4 moles of C fourteen moles of oxygen and twelve moles of hydrogen present.
Balanced chemical equation:
C₂H₄ + 3O₂ → 2CO₂ + 2H₂O
Now the equation became balanced. There are two moles of carbon, four moles of hydrogen and six moles of oxygen are present on both side of equation.

There have been made 2 attempts of oxygen production by potassium permanganate.In the first attempt they have got 75ml oxygen in 3 minutes whearas there have been got 100ml in 5 minutes by the 2nd attempt.In what case the speed of the oxygen production is bigger???
Pls explain your answer
Answers
Answer:
The speed of oxygen production is bigger in the first attempt.
Explanation:
In the first attempt, since 75ml oxygen is produced in 3 minutes, the rate of oxygen production is r = volume of oxygen/time = 75 ml/3 min = 25 ml//min
In the second attempt, since 100ml oxygen is produced in 5 minutes, the rate of oxygen production is r' = volume of oxygen/time = 100 ml/5 min = 20 ml//min
Since r = 25 ml/min > r' = 20 ml/min, the speed of oxygen production is bigger in the first attempt.

How many moles of NaCl are in 2.35 liters of a 4.67 M solution?
Answers
There are 10.97 moles of NaCl in 2.35 liters of a 4.67 M solution.
HOW TO CALCULATE NUMBER OF MOLES:The number of moles of a substance can be calculated by multiplying the molarity by the volume. That is;no. of moles = volume × molarity
According to this question, there are 2.35 liters of a 4.67 M solution. The number of moles is calculated as follows:no of moles = 2.35L × 4.67M
no of moles = 10.97mol

which type of cell is shown in the diagram - a plant cell, a yeast cell or a bacterial cell
Answers
Answer:
bacterial cell plant cells dont have a tail
Explanation:
The type of cell shown in the diagram is the bacterial cell as plant cell do not have tails while bacteria have tail.
Bacteria are prokaryotic unicellular organisms. They have a relatively simple cell structure compared to eukaryotic cells. They also do not possess any membrane-bound organelles such as a nucleus. However, do they possess genetic material (DNA or RNA) in the intracellular space called the nucleoid.
Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes. Prokaryotes are the dominant living creatures on Earth, having been present for perhaps three-quarters of Earth history and having adapted to almost all available ecological habitats.
