noble gases are used in many situations where a safe and constant environment must be maintained. for example, helium is used to provide a protective atmosphere for making fiber optics and semiconductors. argon is used to fill incandescent and flourescent light bulbs to prevent oxygen from corroding the hot filament. why are noble gases used in these situations?

Answers

Answer:

Because they do not naturally react with other elements

Explanation:

Since noble gases do have a fulfilled valence shell, they do not react with other elements because they're already stable by the themselves.

If I remove the table from under the book, what will happen to the book? Think about Newton’s second law of motion. Is there an acceleration? What caused the acceleration?

Answers

Newton’s second law of motion is a dot product of mass and acceleration, if you remove the table from, under the book, gravity will act on the book and pull it downwards to the centre of the earth

Newton's Second law of motion states that "the acceleration of an object depends upon two variables – the net force acting on the object and the mass of the object."

What is chemical reaction?

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved that is mass can nether be created nor be destroyed in a chemical reaction.

There are so many types of chemical reaction reaction like combination reaction, double displacement reaction. The evidence of a chemical reaction are  "the liquid turned pink when mixed" and "over time, a white solid formed at the bottom of the beaker".

How many grams of CO2 are produced using 0.29 moles of O2?

Answers

The mass of CO2 produced using 0.29 moles of O2 is 12.76 grams.

The reaction between carbon and pxygen atom is exprssed as:

C + O2 -> CO2

From he balanced equation, we can see that 1 mole O2 reacted to produce 1 mole of CO2.

Hence if 0.29 moles of CO2 was used in the reaction, the number of moles of CO2 produced will be 0.29 moles as well.

Mass of CO2 = number of moles * molar mass

Mass of CO2 = 0.29 * (12 + 32)

Mass of CO2 = 0.29 * 44

Mass of CO2 = 12.76grams

Hence the mass of CO2 produced using 0.29 moles of O2 is 12.76 grams.

The ribosome of plant cells are sites for the synthesis of proteins. The correct option is (d).

What are ribosomes?

Ribosomes are organelles that take part in the synthesis of proteins. The prokaryotic cell's ribosomes are smaller than the eukaryotic cell's ribosomes.

Currently, ribosomal RNA is a component of the cell's ribosome or protein-building machinery. The process of making proteins, or translation, is carried out by ribosomes.

The ribosome, which translates the genetic code generated in mRNA into an amino acid sequence, is universally responsible for protein synthesis. The two ribosomal subunits, small and big, come together to form the full ribosome, which is used to produce proteins.

Therefore, the correct option is (d) proteins.

Answers

The enthalpy of this reaction is -5315 KJ/mol.

The equation of the reaction is;

2C4H10(g) + 13O2(g) -----> 8CO2 (g) + 10H2O(g)

We know that the enthalpy of reaction can be obtained from the enthalpy of formation of the reactants and products as follows;

ΔHrxn = ΔHf(products) - ΔHf(reactants)

We have the following information from the question;

ΔHf C4H10 = - 125. 6 kJ/mol

ΔHf CO2 = - 393. 5 kJ/mol

ΔHf H2O = - 241. 82 kJ/mol

ΔHf O2 = 0 KJ/mol

Hence;

[(8 × (- 393. 5 )) + (10 × (-  241. 82))] - [2( - 125. 6))]

= -5315 KJ/mol

Answers

Answer:

We have the atoms, and we have the molar mass of Vanadium (listed in the periodic table) which should be 50.94g/mol.

The first step is to convert the 4.18 x 10^23 atoms into moles by dividing the atoms by Avogadro's number (6.02 x 10^23)  

(4.18 x 10^23)/(6.02 x 10^23) = 0.694 moles

Now we know that moles is equal to the mass divided by the molar mass. So now that we have the moles and the molar mass of Vanadium, we can rearrange the equation to find mass. Once you have rearranged it, you have to multiply the moles by the molar mass.

So 0.694 moles x 50.94g/mol = 35.35g of V

Saliva, produced by glands in the mouth, plays an important role in the digestion of food. Saliva contains a chemical, called amylase, that breaks down starch in the food we eat. A scientist conducts an experiment to investigate at which temperatures amylase works the best. He hypothesizes that the reaction will occur fastest if the amylase reaction is conducted near the normal human body temperature of 37ºC (degrees Celsius). In order to test his hypothesis, the scientist measures the reaction rate, which is how fast the amylase breaks down the starch at six different temperatures. The reaction rate is rated on a scale of 0 to 10, with 0 meaning no reaction and 10 meaning the fastest reaction. The results are recorded in the data table.
