biography of the person who discovered o2

Answers

Answer:

Oxygen was discovered independently by two chemists in the late 18th century: Carl Wilhelm Scheele and Joseph Priestley.

Carl Wilhelm Scheele was a Swedish chemist who is credited with the discovery of several elements, including oxygen, chlorine, and molybdenum. He was born on December 9, 1742, in Stralsund, Sweden, and showed an early interest in chemistry. In the 1770s, he made several important discoveries related to oxygen, including the fact that it is a gas and that it is necessary for combustion. However, he did not publish his findings until after Priestley had published his own work on oxygen. Scheele died on May 21, 1786, at the age of 43.

Joseph Priestley was an English scientist, philosopher, and theologian who is best known for his discovery of oxygen. He was born on March 13, 1733, in Birstall, England, and studied theology and science at the University of Leeds. In the 1770s, he conducted a series of experiments in which he isolated and described oxygen. He published his findings in 1774, in a book called "Experiments and Observations on Different Kinds of Air." Priestley's work on oxygen helped to lay the foundations for modern chemistry and the understanding of combustion and respiration. He died on February 6, 1804, at the age of 70.

if 20.0 ml of 0.10 m ba(no3)2 are added to 50.0 ml of 0.10 m na2co3, will baco3 precipitate?

Answers

When 20.0 ml of 0.10 m Ba(NO₃)₂ (aq) and 50.0 ml of 0.10 m Na₂CO₃ (aq) are mixed together, a precipitate of BaCO₃ will be formed.

In aqueous solution, precipitation is defined as the process of turning a soluble substance into an insoluble solid from a supersaturated solution.

Precipitation of a compound generally occur when its concentration exceeds its solubility. This may happen due to temperature changes, solvent evaporation, or mixing of solvents. Precipitation always occurs faster from a highly oversaturated solution.

When the barium chloride solution reacts with sulfuric acid, a white precipitate of barium sulfate is formed in the product side.

When a non-volatile solute is dissolved in an organic solvent, a phenomena known as freezing point depression takes place.

The freezing point of the solvent is lowered below its usual freezing point by the addition of the solute. This is a result of the solute's presence, which causes the solvent's vapour pressure to fall.

How to calculate it?

Molar mass of sucrose is equal to 342.297 g/mol (12 x 12.011 + 22 x 1.008 + 11 x 15.999).

1000 g = 1 Kg

As a starting point, let's determine how many moles of sucrose there are: (mass of sucrose/molar mass of sucrose) = (115.0 g/342.297 g/mol) = 0.3360 mol

Next, determine the molality of the sucrose solution: (moles of sucrose per kilogramme of solvent) = (0.3360 mol per 0.35 kilogramme) = 0.96 mol/kg or 0.96 m

Water does not allow the glucose molecules to associate or dissociate, hence the Van't Hoff factor I is equal to 1.

T f = I x Kf x m) = (1 x 1.853 deg C/m x 0.96 m) = 1.78 deg C is the depression in the freezing point of sucrose solution.

Pure water has a freezing point of 0 degrees Celsius.

So, the freezing point of a solution of sucrose is equal to (0 - 1.78), or - 1.78 degrees Celsius.

About scientific model

In science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations.

Models in marine science

Prof John Montgomery discusses how and why scientists use models, with climate change as an example.

Models are a mental visual way of linking theory with experiment, and they guide research by being simplified representations of an imagined reality that enable predictions to be developed and tested by experiment.

Why scientists use models

Models have a variety of uses – from providing a way of explaining complex data to presenting it as a hypothesis. There may be more than one model proposed by scientists to explain or predict what might happen in particular circumstances. Often scientists will argue about the 'rightness' of their model, and in the process, the model will evolve or be rejected. Consequently, models are central to the process of knowledge-building in science and demonstrate how science knowledge is tentative.

Answers

At equilibrium, there is a much higher concentration of products than reactants.

What is equilibrium?

Equilibrium is a state of balance in which all forces acting on an object are equal and opposite, resulting in the object being motionless. It is a state of being when the forces acting on a system are balanced and no further change will occur unless an external force is applied. Equilibrium can be seen in everyday life; for example, when a pencil is balanced on its pointed tip, the forces of gravity and the reaction of the pencil on the surface are equal and opposite, allowing the pencil to remain motionless.

K= [products]/[reactants]

If K=1 then concentration of reactants and products are equal.

If K>1 that means [Products]>[reactants]

Why is rms calculated?

Answers

The RMS or the root mean square velocity of a gas particle is calculated because the net velocity of a gas sample is always zero.

The velocity of a given sample of gas is calculated because the temperature is directly related to the velocity of the gas particles. The reason we use RMS velocity instead of average velocity is that any gas sample always has its net velocity be zero. This is because the particles of the gas sample are always moving in all directions. So if we take the average velocity of the gas sample which becomes zero, the temperature will also be affected which is not the case in reality. Therefore, RMS velocity is always used instead of average velocity.

in an ionic or covalent substance, electrons are shared or transferred between no more than two atoms at a time. however, in a metallic substance, electrons are shared among all of the metal atoms in the sample. how does this explain why metals are more malleable and ductile than ionic and covalent compounds?

Answers

Since the electrons in metals are shared across all of the metal atoms in the sample as "sea of electrons" which surrounds the metal ions, making metals more malleable and ductile than ionic and covalent substance.

A metallic composition of all metal atoms surrounds the metal ions with a "sea" of shared electrons. It is assumed that this electron sea is the source of the great conductivity, malleability, and ductility that make metals unique.

Metal ions can easily pass by one another and twist the metal without breaking it because of the electron sea in a metallic body. On the other hand, it is more challenging to modify ionic and covalent molecules without rupturing the bonds due to the strong chemical bonds that hold them together. Because of this, ionic and covalent compounds are less ductile and malleable than metals.

When a channel opens, H+ ions will flow out of the mitochondrion if the concentration of  H+ ions inside the mitochondrion is higher than the concentration outside the mitochondrion.

The inner mitochondrial membrane is where H+ ions and electrons from NADH and FADH2 are released. The energy released during the transfer of electrons is used to pump H+ ions into the intermembrane gap as electrons join the electron transport chain. Since H+ ions cannot penetrate the inner mitochondrial membrane and return to the matrix because it is impermeable to protons, there is a larger concentration of H+ ions in the intermembrane space, which creates and maintains a proton gradient across the inner mitochondrial membrane.

Hence, open channel freely passes proton to inner membrane space.
