Using the particle theory how do ice cubes form inside a freezer?

Chemistry
1 answer:
Oksanka [162]3 years ago
6 0

Answer:

The ice cube which was solid has turned into the liquid water because the air temperature is warmer than the freezers. Which means the ice particles gather heat energy from the warmer air. Therefore the ice particles have enough energy to break apart (melt)into smaller particle arrangements.

mario62 [17]
Concentration is found by dividing the mass of solute by the volume of the solution. C = 4.2g/0.25 L. C= 16.8 g/L

Seawater has a ph of 8.1. what is the concentration of oh–?
lara31 [8.8K]
PH scale is used to determine how acidic or basic a solution is.
pH can be calculated as follows;
by knowing the ph we can calculate pOH
pH + pOH = 14
pOH = 14 - 8.1 
pOH = 5.9 
pOH is used to calculate the hydroxide ion concentration 
pOH = -log[OH⁻]
[OH⁻] = antilog(-pOH)
[OH⁻] = 1.26 x 10⁻⁶ M
therefore hydroxide ion concentration is 1.26 x 10⁻⁶ M

A 23.98 gram sample of chromium is heated in the presence of excess iodine. a metal iodide is formed with a mass of 199.6 g. det
Misha Larkins [42]

The empirical formula of the metal iodide is Cr2I.

Mass of Chromium = 23.98

Molar Mass of Chromium = 51.9961

= 0.461 mol

Molar Mass of iodide = 126.9

= 199.6-23.88/126 = 1.394

The ratio between

Chromium and iodinei is1:2.So, the empirical formula is therefore Cr2I

Empirical formula of a chemical compound is the simplest whole number ratio of atoms present in a compound.[1] A simple example of this concept is that the empirical formula of sulfur monoxide, or SO, would simply be SO, as is the empirical formula of disulfur dioxide, S2O2. Thus, sulfur monoxide and disulfur dioxide, both compounds of sulfur and oxygen, have the same empirical formula. However, their molecular formulas, which express the number of atoms in each molecule of a chemical compound, are not the same.
