Answer:
107g
Explanation:
Magnesium fluoride (MgF₂) has a molecular mass of:
Mg: 24,305 g/mol × 1 = 24,305 g/mol
F: 18,998 g/mol × 2 = 37,996 g/mol
MgF₂ = 24,305g/mol + 37,996g/mol = 62,301g/mol. That means the mass of 1,72 mol of MgF₂ is:
1,72 mol F₂ × (62,301g / 1mol) = <em>107g</em>

The answer is covalent bond
Answer:
<h3>The answer is 8.40 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
volume = final volume of water - initial volume of water
volume = 56.4 - 50 = 6.4 mL
We have
We have the final answer as
<h3>8.40 g/mL</h3>

Element which possess different number of "Neutrons" in different situations could be an isotope of the atom
Ex. - 17 Cl 34, 17 Cl 35, 17 Cl 36
They all the isotopes.
Hope this helps!
The statement which is not true is as follows:
- The repulsive force between electrons on different atoms does not matter at all.
Thus, the correct option is C.
<h3>What is Equilibrium?</h3>
An equilibrium may be defined as the condition in which both the reactants and products are present in concentrations that have no additional propensity to alter with time so that there is no noticeable transformation in the possessions of the system.
The causation of repulsive force was thought to be made by the overlap of atomic orbitals and in between the electrons of diverse atoms, it matters a lot.
The equilibrium distance between nuclei of two covalently bonded atoms is called the bond length of that atom. It is the atomic separation at equilibrium.
Equilibrium occurs when the attractive and repulsive forces neglected the effect of each other in a specific state.
Therefore, it is well described above.
