Answer:
C. Lithium is most easily oxidized of the metals listed on the activity series and therefore it will most easily give electrons to metal cations
Explanation:
"Lithium" is a type of alkali metal that has a "single valence electron." Since it is a reactive element, it easily gives up an electron when it is combined with other elements. Such giving up of electron is meant to create compounds or bonds.
Among the common metals listed, "lithium" is the most easily oxidized. This means that it donates its electrons immediately. Such combination makes it exist as a<em> "cation"</em> or <em>"positively-charged."</em>
So, this explains the answer.
There are 20.8 moles of propanol
<h3>Further explanation </h3>
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
1.2 x 10⁵ molecules of propanol
Answer:
<h2>250 cm³</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question we have
Wr have the final answer as
<h3>250 cm³</h3>
Hope this helps you
Answer:
174 K
Explanation:
To answer this question we will use the PV=nRT formula, where:
We <u>input the data</u> given by the problem:
- 1.072 atm * 20.0 L = 1.50 mol * 0.082atm·L·mol⁻¹·K⁻¹ * T
And <u>solve for T</u>:
Meaning the correct answer is the fourth option, 174 K.
