How will carbon behave at room temperature?

Explain, in terms of energy, why the temperature of the reaction mixture increases

Dima020 [189]

Answer:

Magnesium reacts with dilute hydrochloric acid in a conical flask which is connected to an inverted measuring cylinder in a trough of water. The volume of hydrogen gas produced is measured over a few minutes, and the results are used to plot a graph........

Sample of 200mls of 0.5 sulphuric acid,was asked to produce 1.2M of the new solution.Calculate the volume of the new solution

AlladinOne [14]

Answer:

$V_2=83.3mL$

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the volume of the new solution by using the general formula of dilution:

$V_1M_1=V_2M_2$

In such a way, we solve for the final volume, V2, to obtain:

$V_2=\frac{200mL*0.5M}{1.2M}\\\\V_2=83.3mL$

Regards!

A concentrated salt solution has a mass of 5.34 g for a 5.00 ml sample. what is the specific gravity of this solution?

Nutka1998 [239]

The specific gravity of the solution is 1.07, which contains 5.34g for a 5.00ml sample.

Density of a substance is

Density = Mass / Volume

= 5.34/5

= 1.07

Density of water = 1

Specific gravity = Density of substance/density of solvent

Specific gravity = 1.07 / 1

Specific gravity = 1.07

Specific gravity, often known as relative density, is the ratio of a substance's density to that of an industry standard.

If a material has a relative density that is less than 1 compared to the reference, it is less dense than the reference; if it is larger than 1, it is denser. Identical volumes of the two substances have the same mass if the relative densities are equal, or exactly 1.

Which word names melted rock and minerals found beneath Earth's crust?

Anna11 [10]

before the lava rises to the earth's surface it's called magma. Although lava and magma are often used interchangeably, technically magma is the name for the hot molten rock (mixed with gases and mineral crystals) that collects in chambers beneath the Earth's crust.

Consider this hydrocarbon. A hexagon. Is this an aromatic hydrocarbon? Why or why not? Yes, because the carbon chain is made up

grin007 [14]

Answer:

C. No, because the carbon chain is composed of only a single ring.

Polycyclicity, having more than a single ring, is a property of only aromatic hydrocarbons. Therefore, if the hydrocarbon is not polycyclic, it is non-aromatic

Explanation:

Cyclic Hydrocarbons

These are organic compounds which are cyclic in structure. The compound cyclohexane involves a ring of six carbon atoms, each of which is also bonded to two hydrogen atoms

Aromatic hydrocarbons are cyclic ring organic compound which are based on the benzene ring structure.

A. If the hexagon contains single bonds, it is non-aromatic.

B. No. Having a ring shape does not on its own determine the aromaticity of a hydrocarbon.

C. Polycyclicity, having more than a single ring, is a property of only aromatic hydrocarbons. Therefore, if the hydrocarbon is not polycyclic, it is non-aromatic

D. Having double bonds within a ring is not a criteria for being aromatic. Both aromatic and non-aromatic hydrocarbons have double bonds within their rings. However, aromatic hydrocarbons have alternate double and single bonds within their 6-carbon ring structure.

Note: Since the structure of the required hydrocarbon is not shown, the explanation contains attachments of hexagonal structures of three hydrocarbons; one non-aromatic and the other two are aromatic. Cyclohexane is non-aromatic while Benzene and the polycyclic compounds are aromatic.
