Answer:

The properties shown in no. 1 are properties of liquids.

The properties in no.2 belong to gases.

And, The solid's properties are given in no.3

Explanation:

The diagram gives you the answer.

The first figure has atoms which move in their own place, which proves to be a liquid. The second figure shows that the atoms move vigorously and are very far apart, which means the figure constitute to gases.

And, left with only solids, which constitute the third diagram.

An experiment was conducted with a 1.57 gram starting mass of copper. How many grams of cooper were collected if the yield was 8

IRINA_888 [86]

Answer:

1.26 g of Cu

Explanation:

Since we have to find the percentage of the given amount so...

Yield in grams = (Initial mass used / 100) x Percentage Yield

Yield in grams = (1.57 / 100) x 80.6 = 1.26 g of Cu

Phosgene is formed from carbon monoxide and chlorine. At 611 oC, Kc is approximately 16.5 M-1 or L/mol. Calculate Kp (in atm-1)

defon

Answer:

Kp is 0.228/atm

Explanation:

This is the reaction:

CO + Cl<u>₂</u> → CCl₂O

1 mol of carbon monoxide and 1 mol of chlorine produce 1 mol of phosgene.

Formula for Kp which derivates from Kc is:

Kp = Kc (R.T)ⁿᵇ ⁻ ⁿᵃ

Δп = nb (moles in the products) - nₐ(moles in the reactants)

Δп = 1 - 2 = -1

T is T° in K → T°C + 273 = 611°C +273 = 884K

R → Universal constant gas → 0.082 L.atm/mol.K

We replace the data: Kp = 16.5 L/mol (0.082 . 884K)⁻¹ → 0.228/atm

Which statement is true about BF3, a nonpolar molecule? It has nonpolar bonds and a symmetrical structure. It has nonpolar bonds

konstantin123 [22]

I think the correct answer is the first option. It has nonpolar bonds and a symmetrical structure. The structure of a BF3 molecule shows a symmetrical trigonal geometry. The net dipole moment of the molecule is zero therefore it is polar.
