Answer:

5.66g/ml

Explanation:

Mass of Metal Slug, m = 25.17g

Volume of container (flask), v = 59.7ml

Mass of Methanol, M = 43.7g with density, d = 0.791g/ml

Therefore,

Volume of Methanol = M/d = 43.7 / 0.791 = 55.25ml

Volume of Metal slug in the flask = v - V = 59.7 - 55.25 = 4.45ml

Density of Metal slug = mass of metal slug / volume of metal slug

                                   = 25.17 / 4.45 = 5.66g/ml

6. Describe the energy inputs and outputs for the campfire. Use the law of conservation of energy to construct a valid qualitati
Doss [256]

Answer:

Energy in the campfire originates from the potential chemical energy of the wood, before it is burnt to warm and give light around the campfire.

Explanation:

For a camp fire, the energy input is in the form of the potential chemical energy, stored up in the firewood used to fuel the flame.

The energy output is in the form of heat energy that the campfire radiates all around, light energy given off from the flame, and a little bit of sound energy, heard in the cracking of the firewood as they burn in the flame.

chemical energy ⇒ heat energy + light energy + sound energy

Mercury chloride is a commercial fungicide. If the molar mass is 470 g/mol and the percent composition is 85.0% Hg and 15.0% Cl,
ElenaW [278]
Data: molar mass 470 g/mol

Percent composition:

Hg = 85.0%
Cl = 15.0%

Solution:

1)  Convert % to molar ratios

A. Base: 100 g

=> Hg = 85.0 g / 200.59 g/mol = 0.4235 mol

     Cl = 15.0 g / 35.45 g/mol = 0.4231 mol

B. divide by the higher number and round to whole number

Hg = 0.4325 / 0.4231 = 1.00

Cl = 0.4231 / 0.4231 = 1.00

=> Empirical formula = Hg Cl

2) Find the mass of the empirical formula:

HgCl: 200.59 g/mol + 35.45 g/mol = 236.04

3) Determine how many times is the empirical mass contained in the molecular mass:

470 g/mol / 236.04 = 1.99 ≈ 2

=> Molecular formula = Hg2 Cl2.

Answers:

Empirical formula HgCl
Molecular Formula Hg2Cl2
