Answer:

3.00 moles of Lithium bromide will be produced

Explanation:

The reaction that takes place is:

LiOH + HBr → LiBr + H₂O

By looking at the reaction equation, we can see that the reaction of 1 mol of lithium hydroxide (LiOH) produces 1 mol of lithium bromide (LiBr). Thus, 3.00 moles of LiOH would conversely produce 3.00 moles of LiBr.

Naddika [18.5K]

I can give you a clue of getting mass. if it is the atomic number is even multiply by 2 but if the atomic number is odd multiply by 2 and add 1

sodium atomic number = 11 so mass = 11*2 +1 = 23

oxygen. atomic number = 8 so mass = 8*2 = 16

carbon atomic number = 6 so mass = 6*2 = 12

An isotope contains 56 protons, 54 electrons, and 74 neutrons. What is the identity of the isotope? Choose 1 answer:

Dovator [93]

Answer:

Barium.

Explanation:

Each chemical element is characterized by the number of protons in its nucleus, which is called the atomic number Z. But in the nucleus of each element it is also possible to find neutrons, whose number can vary. The atomic mass (A) is obtained by adding the number of protons and neutrons in a given nucleus.

The same chemical element can be made up of different atoms, that is, their atomic numbers are the same, but the number of neutrons is different. These atoms are called isotopes of the element. Isotopes means "same place", that is, since all the isotopes of an element have the same atomic number, they occupy the same place in the Periodic Table. So if a neutron is added to an atom, it becomes an isotope of that chemical element.

The isotopes of an element have the same chemical properties, but differ somewhat in their physical properties.

Barium has an atomic number of 56 (number of protons). Also, the mass number of this barium isotope is 130 (56 protons + 76 neutrons). Finally, since it has 54 electrons, two negatively charged electrons less than the number of positively charged protons, this isotope is a cation with oxidation number +2.

What mass of Fe can be produced by the reaction of 75.0 g CO with excess Fe2O3 according to the equation: Fe2O3(s) + CO(g) → Fe(

lyudmila [28]

Here we have to get the mass of the iron (Fe) produces in the reaction between ferric oxide (Fe₂O₃) and carbon monooxide (CO) to produce carbon dioxide and iron.

The amount of Fe produced in the reaction is B. 99.7g.

The balanced form of the reaction given is: Fe₂O₃ (s) + 3CO = 2Fe + 3CO₂.

Now as per the reaction 3 moles of CO produce 2 moles of Fe.

The molar mass of CO and Fe are 28.01g/mol and 55.845g/mol.

Thus (3×28.01) 84.03g of CO produces 111.69g of Fe.

Hence, 75.0g of CO produces $\frac{111.69}{84.03}$ ×75.0 = 99.687g of Fe or 99.7g of Fe.

A. If in the reaction 49.8g Fe is produced in the reaction then $\frac{84.03}{111.69}$ ×49.8 = 37.467g of CO should react. Thus the option is wrong.

C. To produce 224g of Fe $\frac{84.03}{111.69}$ ×224 = 168.526g of CO will consumed. Thus it is wrong statement.

D. To generate 299g of Fe $\frac{84.03}{111.69}$ ×299 = 224.952g of CO will consumed. Thus it is wrong statement.
