If a jet's cruising altitude is 32,200 ft (to three significant figures), this distance in km is 9.82 km.
<h3>What are significant figures?</h3>
Significant figures are the number of digits in a value, often a measurement, that contributes to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit.
In this case, given the conversion factors from miles to kilometres and from miles to feet, we can directly compute the jet’s cruising altitude in kilometres as shown below:
=9.82 km

Answer:
In a covalent bond electrons are <u>shared</u> between atoms
Hi there,
In a molecule<span>, </span>atoms<span> are bonded together by single, double, or triple bonds. An </span>atom<span> has a nucleus surrounded by electrons. ... So another </span>difference between atoms and molecules<span> is that when similar </span>atoms<span> combine together in varying numbers,</span>molecules<span> of different properties can be formed.

Ans: Moles of Fe(OH)2 produced is 5.35 moles.
Given reaction:
Fe(s) + 2NiO(OH) (s) + 2H2O(l) → Fe(OH)2(s) + 2Ni(OH)2(aq)
Based on the reaction stoichiometry:
1 mole of Fe reacts with 2 moles of NiO(OH) to produce 1 mole of Fe(OH)2
It is given that there are:
5.35 moles of Fe
7.65 moles of NiO(OH)
Here the limiting reagent is Fe
Therefore, number of moles of Fe(OH)2 produced is 5.35 moles.
