Answer:
The rows on the periodic table are called periods. All the elements in a period have valence electrons in the same shell. The number of valence electrons increases from left to right in the period. When the shell is full, a new row is started and the process repeats.

Answer:
First of all you need to know that chemical properties are those who are determined by chemical tests and are related to the reactivity of chemical substances. In those statements you have 4 reactions, except on "conducts electricity". That is a physical property.
Explanation:
A chemical reaction is a way in which the atoms of the elements regroup to form new substances.
The choices can be found elsewhere and as follows:
A)The reaction requires the collision of three particles with the correct energy and orientation.
<span>B) All reactions that occur in one step are slow. </span>
<span>C)The probability of an effective three-particle collision is low. </span>
<span>D) The transition state is low in energy.
</span>
I think the correct answer from the choices listed above is option C. If the uncatalyzed reaction occurs in a single elementary step, it is a slow reaction because the probability of an effective three-particle collision is low.
- <u>Physical Properties :</u>
- It is a crystalline colorless solid structure it is soluble in solution such as ether, alcohol, and chloroform but insoluble in water.
- It is dangerous when it is dry and is very volatile and decomposes when it reaches 103 c.
2. <u>Chemical Properties :</u>
- It causes swelling of the skin and undergoes free radical products that are highly reactive.
- It is irritant when it contacts the skin it breaks down to yield oxygen and benzoic acid.
<u>Explanation:</u>
- Benzoyl Peroxide is widely used in industry at large scale.
- It is formed when there is a reaction between hydrogen peroxide and benzoyl chloride.
- Benzoyl peroxide is used in bread and cheese as the bleaching agent and also used in cosmetics as hair coloring.
- Because of its antibacterial property and a peroxide group it is applied to the human skin to treat acne.
Answer:
Are you tryna make a 3d object or you need a drawing?
Explanation:
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again
