Just took it, Hydrogen bonds

Answer: B: Hydrogen bonds

Explanation: Hydrogen bond is a bond formed between a hydrogen atom and a electronegative atom such as fluorine, oxygen or nitrogen. It is a strong bond.

Ionic bond is formed by the transfer of electrons between metals and non metals.

London dispersion force is a temporary attractive force that results when the electrons in adjacent atoms occupy positions that make the atoms form temporary dipoles.

Dipole induced dipole interactions is a weak attraction that results when a polar molecule induces a dipole in a neighboring atom or a non polar molecule by disturbing the arrangement of electrons.

The following system is at equilibrium:
Delvig [45]

Answer:

1) No shift

2) No shift

3) Leftward shift

4)Rightward sifht

Explanation:

1) 2) Adding N or Removing N in the equilibrium will produce No shift, because of its solid state, the N is not contemplated in the equilibrium equation:

K=\frac{[L]^2}{[M]^3}

3) Increasing the volume produces a decrase in the preassure due to the expansion of the gases. This will cause a leftward shift, because the system will try to increase the moles of gas and in consecuence of this, also increase the preassure.

4) Decreasing the volume has the opposite effect of the item 3): the preassure will increase and the system will consume moles of gas to decrease it, producing a rightward shift.

Milk of magnesia has the chemical formula Mg(OH)2. What is the mass of 3.2 moles of milk of magnesia? The molar Mass of magnesiu
GenaCL600 [577]
To calculate the mass of milk of magnesia given, we need certain data like molar mass of the compound which needs the atomic mass of the atoms in the compound. We calculate as follows:

Molar mass of <span>Mg(OH)2 = 24.3 g/mol + (2 x (16 + 1.0)) = 58.30 g/mol

Mass = 3.2 mol (</span>58.30 g/mol) = 186.56 grams
