Why does an egg sink in fresh water but float in salt water??

Chemistry

maria [59]3 years ago

If an object is less dense than the water around it, it will float. Because salt water is denser than freshwater, some things float more easily in the ocean—or extremely salty bodies of the water, such as the Dead Sea. You can make your own dense water by adding salt to tap water.

How many grams of sodium hyrdioxde are in 251.0ml f 0.600m
Furkat [3]

Answer:

There are 6.024 grams of sodium hydroxide in the solution.

Explanation:

Molarity=\frac{Moles}{Volume (L)}

Moles (n)=Molarity(M)\times Volume (L)

Moles of sodium hydroxide = n

Volume of sodium hydroxide solution = 251.0 mL = 0.251 L

Molarity of the sodium hydroxide = 0.600 M

n=0.600 M\times 0.251 L=0.1506 mol

Mass of 0.1506 moles of NaOH :

40 g/mol\times 0.1506 mol = 6.024 g

There are 6.024 grams of sodium hydroxide in the solution.

What is the difference between organic and inorganic compounds give an example of each?
dusya [7]
The main difference is in the presence of a carbon atom; organic compoundswill contain a carbon atom (and often a hydrogen atom, to form hydrocarbons), while almost allinorganic compounds do not contain either of those two atoms. While mostinorganic compounds do not contain carbon, there are a few that do.

An organic compound is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon

Inorganic compounds can be defined as any compound that is not organic compound. Some simple compounds which contain carbon are usually considered inorganic. These include carbon monoxide, carbon dioxide, carbonates, cyanides, cyanates, carbides, and thiocyanates.
