How many grams of o2(g) are needed to completely burn 70.2 g of C3H8(g)

Chemistry
1 answer:
Lubov Fominskaja [6]3 years ago
6 0
First you must write a balanced chemical equation.

C3H8 + 5O2 --> 3CO2 + 4H2O

From there, we can set up the stoichiometry equation to solve.

g O2= 70.2 g C3H8 X (1 mol C3H8/44.0962g C3H8) X (5 mol O2/1 mol C3H8) X (31.998g O2/1 mol O2)

Now solve, and you should get 254.7 g O2. Hope this helped!

The molecule CO2 is arranged in a linear molecular geometry. TRUE FALSE
antiseptic1488 [7]

I would say true because the Valence Shell Electron Pairs will Repel each other. When they do they are forced to the opposite side of the Carbon atom giving CO2 a linear molecular shape. The CO2 bond angle will be 180 degrees since it has a linear molecular geometry.

sorry if im wrong

Nuclear reactions in a reactor produce a lot of thermal
Leokris [45]

Answer:

Heat flows from the reactor to the water

Explanation:

The thermal energy mentioned in the description is another way to say heat. The energy that is produced by the nuclear reactions leaves the reactor and enters the water, warming it.

The passage does <em>not </em>say that heat flows in the form of electricity, but rather that the turbines turned by the steam produce electricity.

The passage does <em>not </em>say that the steam produces the heat, but rather that the boiling of the water (caused by the heat) produces steam.

Write the balanced chemical reaction for the following nitrogen cycle reactions. These reactions are mediated by bacteria and pl
Leto [7]

Answer:

Nitrification is a biological process by which ammonia is oxidized to nitrites (NO_{2} ^{-}) and then to nitrates (NO_{3} ^{-}) by action of specialized bacteria in nature (such as <em>nitrosomonas</em> and <em>nitrobacter</em>).

Explanation:

This two-step process utilizes molecular atmospheric oxygen and ammonia and ammonium components of soil and nature.

<em>(a.) Ammonia and ammonium compounds to nitrite</em>

NH_{4} ^{+} + O_{2} → NO_{2} ^{-} + 4H^{+}

2NH_{3} ^{+} + 3O_{2} → 2NO_{2} ^{-} + 2H^{+} + 2H_{2} O

<em>(b.) Nitrite to nitrate</em>

2NO_{2} ^{-} + O_{2} → 2NO_{3} ^{-} + energy

<em>(c.) The reverse process involves reduction of nitrates to molecular nitrogen, called denitrification (with succinic acid in the equation below).</em>

4NO_{3} ^{-} + 10H^{+} + (CH_{2})_{2}(COOH)_{2} → 2N_{2} +4CO_{2}  + 8 H_{2} O

(NO and N_{2}O is an intermediate product in this process.)
