What is ionic bonds quizlet?.

1 answer:

4 0

The attraction that keeps together ions with opposing charges is known as an ionic bond. It develops when metal atoms give their electrons to nonmetal atoms.

<h3>An ionic bond: what makes one?</h3>

The whole transfer of a valence electron or electrons between atoms is known as an ionic bond. This particular kind of chemical connection results in the production of two ions with opposing charges. In ionic bonding, the metal gives up its electrons to be a positively charged cation, while the nonmetal takes them to form a negatively charged anion.

<h3>An ionic connection is present where?</h3>

Metals and non-metals form ionic connections with one another. Ionic bonds exchange valence electrons between atoms, as opposed to covalent bonds. The difference between non-metals versus metals in ionic bonding in terms of electronegativity is greater than 1.7. The non-metal atom receives the metal atom's electrons via transfer.

What is the mass of 0.015 moles of NaOH?

JulsSmile [24]

Answer:

Mass = 0.6 g

Explanation:

Given data:

Moles of NaOH = 0.015 mol

Mass of NaOH = ?

Solution:

Number of moles = mass/ molar mass

by rearranging this formula,

Mass = number of moles × molar mass

Molar mass of NaOH is 40 g/mol

by putting values,

Mass = 0.015 mol × 40 g/mol

Mass = 0.6 g

For the reaction ? Fe+? H2o ⇀↽? Fe3o4+? H2 , a maximum of how many grams of fe3o4 could be formed from 354 g of fe and 839 g of

Evgesh-ka [11]

The given reaction is:

3Fe + 4H2O → Fe3O4 + 4H2

Given:

Mass of Fe = 354 g

Mass of H2O = 839 g

Calculation:

Step 1 : Find the limiting reagent

Molar mass of Fe = 56 g/mol

Molar mass of H2O = 18 g/mol

# moles of Fe = mass of Fe/molar mass Fe = 354/56 = 6.321 moles

# moles of H2O = mass of h2O/molar mass of H2O = 839/18 = 46.611 moles

Since moles of Fe is less than H2O; Fe is the limiting reagent.

Step 2: Calculate moles of Fe3O4 formed

As per reaction stoichiometry:

3 moles of Fe form 1 mole of Fe3O4

Therefore, 6.321 moles of Fe = 6.321 * 1/ 3 = 2.107 moles of Fe3O4

Step 4: calculate the mass of Fe3O4 formed

Molar mass of Fe3O4 = 232 g/mol

# moles = 2.107 moles

Mass of Fe3O4 = moles * molar mass

= 2.107 moles * 232 g/mol = 488.8 g (489 g approx)
