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.

?cobalt has a density of 8.90 g. what volume would 17.8 g of Cobalt occupy?

Airida [17]

Answer:

Explanation:

Given parameters:

Density of cobalt = 8.9gcm⁻³

Mass of cobalt = 17.8g

Solution

Density can be defined as the mass per unit volume of a substance:

Density = $\frac{mass in g}{volume in cm^{3} }$

The unknown in the problem is Volume:

Volume = $\frac{mass}{Density}$

Volume = $\frac{17.8}{8.9}$ = 2cm³

Which parts (postulates) of Dalton's atomic theory has been modified in light of later discoveries

professor190 [17]

Explanation:

1) Atoms can not be subdivided. It has been changed as it is possible to divide an atom into Protons, Neutrons and Electrons as well as other smaller particles.

2) The regulations for the chemical mixture have always been altered to the rules for the chemical combination in the creation of organic compounds may be denied.

3)Atoms are of a particular element are identical in all respects i. e. they have same mass and similar properties.

It was modified. And according. to new search;

Atoms of the same element may not be always identical.

Given the chemical equation: Fe2O3 + 3CO --> 2Fe + 3CO2

lapo4ka [179]

Answer:

The answer to your question is 160 g of Fe₂O₃

Explanation:

Data

mass of Fe = 112 g

mass of CO = in excess

mass of Fe₂O₃ = ?

Balanced chemical reaction

Fe₂O₃ + 3CO ⇒ 2Fe + 3CO₂

Process

1.- Calculate the molar mass of Fe₂O₃ and Fe

Molar mass Fe₂O₃ = (56 x 2) + (16 x 3) = 112 + 48 = 160 g

atomic mass of Fe = 56

2.- Use proportions to calculate the mass of Fe₂O₃ needed

160 g of Fe₂O₃ ------------------- 2(56) g of Fe

x g of Fe₂O₃ ------------------ 112 g of Fe

x = (112 x 160) / 2(56)

x = 17920/112

x = 160 g of Fe₂O₃

Studentka2010 [4]

The answer is B.
You can rule C out because divergent means moving away. Rule out A because there is an oceanic and continental plate, not 2 of the same type. Rule D out for the same reason.
