1. Ba(OH)2 give the correct name for the ionic and covalent compounds

AlladinOne [14]

Answer:

The characteristic best supports its formation from sedimentary processes is "It has many layers."

Explanation:

When sediments deposit and solidifies then it results in the formation of sedimentary rocks.The given picture shows that this rock has many horizontal lines of different width and color. This shows that this rock is formed by many different layers. Thus, we can conclude that the characteristic which best supports its formation from sedimentary processes is that it has many layers. The layers present gives us an idea about the past events that has occurred for the formation of the or the deposition of the sedimentary rock.

1.00 L of a gas at STP is compressed to 473mL. What is the new pressure of gas?

Ratling [72]

Hello!

1.00 L of a gas at STP is compressed to 473 mL. What is the new pressure of gas?

We have the following data:

Vo (initial volume) = 1.00 L

V (final volume) = 473 mL → 0.473 L

Po (initial pressure) = 1 atm (pressure exerted by the atmosphere - in STP)

P (final pressure) = ? (in atm)

We have an isothermal transformation, that is, its temperature remains constant, if the volume of the gas in the container decreases, so its pressure increases. Applying the data to the equation Boyle-Mariotte, we have:

$P_0*V_0 = P*V$

$1*1 = P*0.473$

$1 = 0.473\:P$

$0.473\:P = 1$

$P = \dfrac{1}{0.473}$

$\boxed{\boxed{P \approx 2.11\:atm}}\:\:\:\:\:\:\bf\green{\checkmark}$

Answer:

The new pressure of the gas is 2.11 atm

Which of he following is a secondary alkanol?

hodyreva [135]

Answer: Thus $CH_3CH(OH)CH_3$ is a secondary alkanol.

Explanation:

Alkanol are compounds which contains carbons bonded by single bonds and contains hydroxy (-OH) as functional group.

Primary alkanol are those compounds which contain hydroxyl group attached a carbon which is further attached to a single carbon atom. Example: $CH_3CH_2CH_2OH$ and $CH_3CH_2CH_2CH_2OH$

Secondary alkanol are those compounds which contain hydroxyl group attached to a carbon which is further attached to two more carbon atoms.Example: $CH_3CH(OH)CH_3$

Tertiary alkanol are those compounds which contain hydroxyl group attached to a carbon which is further attached to three more carbon atoms. Example: $C(CH_3)_3OH$

Thus $CH_3CH(OH)CH_3$ is a secondary alkanol.

When looking at a chemical reaction, the substance present before the reaction takes place are called the (5) and the substance

faltersainse [42]

Answer:

Explanation:

When looking at a chemical reaction, the substance present before the reaction takes place are called the (5)

REACTANT

and the substance produced after the reaction are the (6).

PRODUCT

know through the Law of Conservation of (7)

MATTER

that nothing is created or destroyed. This is reflected in a (8

BALANCED

chemical equation, where the NUMBER OF atoms of each element on each side of the arrow is (9)-

equal

or the same.

REMEMBER: WHEN BALANCING EQUATIONS YOU CANNOT CHANGE THE SUBSCRIPTS OF THE COMPOUNDS, YOU CAN ONLY SHOW BY THE COEFFICIENTS HOW MANY MOLECULES YOU HAVE!
