sashaice [31]

Answer:

Tara does not get the same results when she conducts the experiment

Explanation:

<em>The most likely reason Tara suggested to Victor to perform the experiment again before publication would be because she did not get the same results when she conducted the experiment.</em>

A good scientific research or experiment should have an element of reproducibility. In order words, the claim made in published scientific research should be reproducible by any other scientist that decides to replicate the research. <u>Tara repeated Victor's experiment in order to check its reproducibility and when she could not reproduce the results, she had to tell Victor to conduct the experiment again before deciding to publish it.</u>

Although the nucleus of an atom is very important, it is the ___ of the atom that determine its chemical properties
aleksandrvk [35]
<span>Although the nucleus of an atom is very important, it is the electrons of the atom that determine its chemical properties.

Number of electrons of an atoms (the number of electrons in the outermost level mostly) determine the type of the element (whether it is a metal, metalloid or non-metal).
Based on this, the types of bonds that the atom can form (whether ionic or covalent) is determined, the type of reactions that the element can form is known and the elements that can react with it are also know.</span>

Nitric oxide (NO) reacts with oxygen gas to produce nitrogen dioxide. A gaseous mixture contains 0.66 g of nitric oxide and 0.58
tigry1 [53]

Answer:

NO is the limiting reagent.  

In this reaction 0.886 mole of NO2 is produced

Explanation:

The chemical equation for this reaction is  

2NO(g) + O2(g) → 2NO2(g)

In this limiting reagent reaction, 2 moles of NO reacts with one mole of O2  to produce 2 mole of 2NO2

0.886 mole of NO * (2 mole of NO2/2 mole of NO) = 0.886 mole of NO2

0.503 mole of O2 * (1 mole of NO2/1 mole of O2) = 1.01 mole of NO2

Hence, NO is the limiting reagent.  

In this reaction 0.886 mole of NO2 is produced
