C2H4 + O2 → CO2 + H2O

eqn is unbalanced - balancing by counting no. of C n H atoms

C=2 n H=4 in one C2H4

so the reaction will form two CO2 + two H2O

counting no. of O atoms: 2*2 + 2*1

=4+2

=6

Given unbalanced chemical equation: C2H4 + O2 → CO2 + H2O


Before applying conservation of mass, the equation must be balanced:

C2H4 + xO2 → 2CO2 + 2H2O

With 2CO2 + 2H2O as the final products, there are 2x2 + 2x1 = 6 O atoms.


The answer is 6.

arlik [135]

Answer:

The answer to your question is: 5 friends

Explanation:

Data

Larry bought 12 1/2 pounds of candy

gave each friend 2 1/2 pounds

number of friends = ?

Process

Convert mixed fractions into improper fractions

           12 1/2 = (24 + 1) / 2 = 25 /2

            2 1/2 = (4 + 1) / 2 = 5/2

Divide the fractions

                                \frac{25}{2}  / \frac{5}{2}

                                = \frac{50}{10}

                               = 5

Larry gave candies to 5 of his friends

Circle the letter next to each sentence that is true concerning the compressibility of gases. a. The large relative distances be
Anuta_ua [19.1K]

Answer:

The large relative distances between particles in a gas means that there is considerable empty space between the particles.

The assumption that particles in a gas are relatively far apart explains gas compressibility.

Compressibility is a measure of how much the volume of matter decreases under pressure.

Energy is released by a gas when it is compressed

Explanation:

The kinetic molecular theory establishes that gases are composed of molecules. These molecules of gas are far apart from each other hence there is a considerable empty space between the gas molecules. As a result of these empty spaces between gas molecules, it is possible to compress a gas.

Compressibility is defined as a measure of how much the volume of matter decreases under pressure. When a gas is compressed, work is done on the gas and energy is evolved hence the gas heats up.
