How many grams of O2 are needed to completely react with 2 moles of N2 ? Enter your answer as a number (do not enter the units o
soldi70 [24.7K]

Answer:

64

Explanation:

Nitrogen combines directly with oxygen at very high temperatures to form nitrogen(ii) oxide. This is the reaction that occurs during lightning flashes. Atmospheric nitrogen and oxygen combines during the high temperatures obtained in lightning flashes to form nitrogen (ii) oxide.

Equation of the reaction is given below:

N(g) + O(g) ---> 2NO(g)

From the equation of the reaction, 1 mole of nitrogen gas combines with one mole of oxygen gas to produce 2 moles of nitrogen (ii) oxide.

Therefore, 2 moles of oxygen gas will react with 2 moles of nitrogen gas

Mass of oxygen gas that is 2 moles of the gas is obtained from the formula; mass = number of moles * molar mass

Molar mass of oxygen gas = 32.0 g/mol

Mass of 2 moles of oxygen gas = 2 * 32.0 = 56 g

Therefore, the mass of oxygen required in grams is 64

How many cycles of oscillation does the radiation from a cesium-133 atom complete during one mosquito wing beat?.
kondaur [170]

The frequency of radiation from a Cesium-133 atom is 9,192,631,770 cycle/s

= 9.192631770×10^{9} cycles/s

The number of cycles of radiation in one second is 9.192631770×10^{9}

The number of cycles during 1 mosquito wing beat,

i.e., the number of cycles in \frac{1}{605} s

= (9.192631770×10^{9})(\frac{1}{605} )

= 1.519×10^{7} cycles/beat

What is a hypothesis?
earnstyle [38]

Answer: D.) a suggested answer to a problem

Explanation:

A hypothesis is a supposition, suggested answer or a proposed explanation based on limited evidence which can be use to start an investigation. A hypothesis is more than a guess but less than a established theory and it can be tested through study and experiments.

<u>A hypothesis is part of the scientific method </u>because it is a prediction which can be tested and the results from those experiments may disprove a hypothesis, but can never entirely prove one.

It is not a conclusion because it is an idea which tries to explain an observation. It is not information collected from experiments because hypothesis are formulated before carrying out the experiments and it is not a widely accepted idea because it just proposes a tentative explanation about a phenomenon.
