50 960 cigarettes. If Cliffhanger smokes 1 pack of cigarettes per day, he will smoke 50 960 cigarettes in 7 years.

We use the <em>factor label method </em>to convert

years → weeks → days → packs → cigarettes

No of days = 7 yr x (52 wk/1 yr) x (7 days/1 wk) = 2548 days

No. of packs = 2548 days x (1 pack/1 day) = 2548 packs

No. of cigarettes = 2548 packs x (20 cigarettess/1 pack) = 50 960 cigarettes

Explain, in terms of subatomic particles, why atoms of H-1, H-2, and H-3 are each electrically neutral.
jasenka [17]

The atoms are all electrically neutral because the number of protons is equal to the number of electrons.

<h3>What is electrical neutrality?</h3>

An atom is electrically neutral when the number of protons is equal to the number of electrons.

In the cases of H-1, H-2, and H-3, the nuclides have one electron an one proton. The different mass numbers arise from differences in the number of neutrons. Hence in all cases, the nuclides are electrically neutral.

Under equilibrium condition, what is the probability of an electron state being occupied if it is located at the Fermi level
Sav [38]

Answer:

Hi

The Fermi Level is a term used to describe the set of electron energy levels at a temperature of absolute zero. Fermi's energy concept is important for the understanding of the electrical and thermal properties of solids. Both electrical and thermal processes involve energy values of a small fraction of an electron-volt. In thermal equilibrium, the net current of both electrons and holes is zero.

How many grams of water can be produced when 8.73 moles of benzene (C6H6) react with excess oxygen?. . Unbalanced equation: C6H6
Alex_Xolod [135]
<span>2 C6H6 + 15 O2 = 12 CO2 + 6 H2O
</span>
2 moles C6H6 -------------------- 6 moles H2O
8.73 moles C6H6 --------------- ( moles H2O)

( moles H2O) = 8.73 x 6 / 2

( moles H2O) = 52.38 / 2

= 26.19 moles of H2O

Molar mass H2O = 18.00 g/mol

1 mole -------------- 18.00 g
26.19 moles ----- ( mass of H2O)

mass of H2O = 26. 19 x 18.00 => 471.42 g of water

hope this helps!
