Ferrosoferric oxide and hydrogen gas are the products of this reaction.

<h3>Explanation:</h3>

Iron is the metallic element with the atomic number 26. It has a valency of both 2 and 3 which forms two types of oxide - ferrous oxide and ferric oxide.

Iron reacts with water with a metal and acid reaction, which forms both the iron oxide and evolves hydrogen gas. The hydrogen gas escapes the system and the mixture of iron oxide is left over in the system. The mixture is denoted by the formula $Fe_3O_4$ and is called ferrosoferric oxide.

This reaction is reversible and is reversed if hydrogen gas is passed over heated ferric oxide in increased pressure.

A solution contains 72.0 g of HCI and 468 g of (C6H6). what is the mole fraction of benzene

erica [24]

Molar mass (MM) of benzene C6H6
C = 6 * 12 = 72u
H = 6 * 1 = 6u
MM C6H6 = 72 + 6 = 78 g / mol
Benzene - Molar Mass = 78 g --------- 1 mol
Of A Mix has 468 g -------------- x

78x = 468
X = 468/78
X = 6 moles

Molar mass (MM) of Hydrochloric Acid HCl H = 1 * 1 = 1u
CI = 1 * 35 = 35u
MM HCl = 1 + 35 = 36 g / mol

Hydrochloric Acid - Molar Mass = 36 g ---------- 1 mol
Of A Mix has 72 g ------------ y

36y = 72
Y = 72/36
Y = 2 moles

Thus, a mixture has a total of 8 moles (6 mol + 2 mol).
Dividing One Mole Amount of Each Substance by the Number of Total Mole Amounts, Then we will obtain a Molar Fraction of Each:
Molar fraction make benzene = (6/8) simplify 2 = 3/4
Molar Fraction to make Hydrochloric Acid = (2/8) = simplify 2 = 1/4

Note:. The sum of the molar fractions of the always give goes 1, we have: 3/4 + 1/4 = 1

ANSWER:
 $\boxed{\frac{3}{4}}$

Match the SI unit to the quantity it measures. second gram kelvin mole ampere meter candela kilogram nanosecond mass arrowRight

Gemiola [76]

SI unit- Quantity

second- time

kilogram- mass

kelvin- temperature

ampere- electric current

S.I. Unit of time is second.

S.I. Unit of mass is kilogram.

S.I. Unit of temperature is kelvin.

S.I. Unit of electric current is ampere.

So match will be as follows:

second- time

kilogram- mass

kelvin- temperature

ampere- electric current

On a container of chicken broth you notice the instructions to ""shake well before serving."" Which of the following best descri

prohojiy [21]

Answer:

The correct option is: D. A suspension

Explanation:

A suspension is a type of heterogeneous mixture in which solid particles are suspended through out the bulk of the solvent through mechanical agitation. The solid phase is also known as the internal phase and the solvent is known as external phase. In a suspension, the solid particles are generally larger than one micrometer and thus are unable to dissolve in the medium. The solid particles of a suspension are large enough to get precipitated.

Therefore, in the given situation, the chicken broth is a suspension as the contents or solid particles of the container needs to be suspended in the solvent by shaking to prevent sedimentation.

According to the periodic table of the elements, which set of elements has similar properties?

erma4kov [3.2K]

In chemistry, "chemical properties" of elements usually refers to the electron affinity of an atom (number of valence electrons) This is because atoms with the same number of valence electrons will form similar compounds with other atoms, and undergo the same types of reactions.

Out of this list: He, Ne and Ar are all group 18 elements (Noble gases)
Therefore they have similar chemical properties.
