Ionic bonds happen when Metals give electron to non-metals and covalent bonds happen when Non-metals give electrons away. Knowing this:

-NaF = ionic (Na is a metal, F is a non-metal)

-NF3 = Covalent (N is a non-metal, F is a non-metal)

-SiF4 = Ionic (Si is a metalloid, F is non-metal)

-CaF2 = ionic (Ca is a metal, F is a non-metal)

-NH4F = covalent (N is a non-metal, H is a non-metal, F is a non-metal)

Hope this helps

Complete this sentence: The total mass of the products in any chemical reaction is equal to
Komok [63]

Answer:

This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.

2 SO2(g) + O2(g) 2 SO3(g) Assume that Kc = 0.0680 for the gas phase reaction above. Calculate the corresponding value of Kp for
son4ous [18]

Answer: The corresponding value of K_p for this reaction at 84.5°C is 0.00232

Explanation:

2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)

Relation of with is given by the formula:

K_p=K_c(RT)^{\Delta ng}

where,

= equilibrium constant in terms of partial pressure = ?

K_c = equilibrium constant in terms of concentration = 0.0680

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature  =84.5^0C=(273+84.5)K=357.5K

\Delta n_g = change in number of moles of gas particles = n_{products}-n_{reactants}=2-3=-1

Putting values in above equation, we get:

K_p=0.0680\times (0.0821\times 357.5)^{-1}\\\\K_p=0.00232

Thus the corresponding value of K_p for this reaction at 84.5°C is 0.00232

Which of the following is an acid-base neutralization reaction? (1 point)
GuDViN [60]
It would be NaOH + HCl → <span>NaCl + H2O
</span>
NaOH is sodium hydroxide, which is a strong base. HCl  is hydrochloric acid, which is a strong acid. 

You have a strong base and a strong acid on the left side, however, at the result side, you end up with NaCl + H2O. Sodium chloride is simply table salt and H2O is just water, thus it has been neutralized.
