when an electric current is passed through water during the process of electrolysis, two gases are formed. One gas has a boiling

point of negative 183 degrees celcius and the other has a boiling point of negative 253 degrees celcius. Has a physical or chemical change occurred? Explain.

Answer is: <span>chemical change occurred.
Electrolysis reaction: 2H</span>₂O → O₂ + 2H₂.
In thic electrolysis reaction two gases are formed, one is oxygen with boiling point of -183°C and second one is hydrogen with boiling point of -253°C. This is chemical change because from one molecule two molecules are produced and because they have new boiling points, boiling point of water is 100°C.

Select the correct answer from each drop-down menu.
Grace [21]

Answer:

An SCl2 molecule has <u>polar</u> bonds and a <u>bent angular</u> molecular shape. As a result, an SCl2 molecule is <u>polar.</u>

Explanation:

It is a covalent compound made up of angular molecules that contain two chlorine atoms attached to one sulfur atom. Sulfur undergoes sp3 hybridization and has two pairs of nonbonding electrons. Given their geometry and the difference in electronegativity between chlorine and sulfur, they are molecules with a marked polar character. The bond angle between the sulfur atom and the two chlorine atoms is 109.5°, since the two vectors are of equal intensity but their directions do not coincide; if they are added vectorially, they do not cancel each other out, making the molecule polar.

For a school event 1/6 of the athletic field is reversed for the fifth -grade classes the reserved part of the field is divided
SVETLANKA909090 [29]

Answer:

\frac{1}{24}

Explanation:

Given:

For a school event, 1/6 of the athletic field is reserved for the fifth -grade classes and the reserved part of the field is divided equally among the 4 fifth grade classes in the school.

To find: fraction of the whole athletic field reserved for each fifth class

Solution:

Fraction of the whole athletic field reserved for four fifth classes = \frac{1}{6}

So, fraction of the whole athletic field reserved for each fifth class = \frac{1}{4}(\frac{1}{6})=\frac{1}{24}

Which skier will have a greater potential energy? Justify your answer.
pochemuha

Answer: Skier 1 will have more potential energy because he is higher than skier 2

Explanation: Gravitational potential energy is the energy possessed by a body by virtue of its position or height.

P.E=m\times g\times h

m= mass of the body

g= acceleration due to gravity

h= height of body

Thus if the masses of two bodies are same, the one with greater height possess greater potential energy.
