Explain why we did not see distinct lines (like on an emission spectrum) when the metal salts were burned.

Actually when we burn metal salts, we cannot actually really see distinct lines to appear because in reality, they are not really visible to the human eye. There is only a certain range of wavelength of light that our eyes can see.

To state in other way, some metal salts will give off light which has wavelengths that are outside of the visible region of the electromagnetic spectrum.<span> </span>

VladimirAG [237]

Answer:

In sea water;

The salt is the solute while the water is the solvent

In soda water;

The water is the solvent, the carbon dioxide is the solute

In air;

The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes

Explanation:

A solution is a homogeneous mixture of two or more substances which includes a solvent and a solute. A solute in a solution is dissolved in the solvent of the solution.

Therefore, the solvent is the major part of a solution as it takes in the solvent to form the solution.

In sea water, a solution with a high concentration of salts

The salt is the solute while the water is the solvent

In soda water,  which is a mixture of CO₂ in water,

Here we have in the soda solution, the water is the solvent while the carbon dioxide is the solute

The water is the solvent, the carbon dioxide is the solute

Air a solution made up by a mixture of Nitrogen 78%, oxygen 21%, and small amount of water carbon dioxide and argon

The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes.

Why do non-metals want to form ions?
vova2212 [387]

Answer:

Explanation:

Non-metals want to be stabilized by making the utmost electron shell complete.

Non-metals form ions when they bond with metals to form an ionic bond. But sometimes, they also form ions with non-metals like NH4Cl.

They take away the electrons from the other ion that it bonds with.

I need Helpppp with my chemistry while we are out of school. I don't have a good teacher and he's not helping since it's his las
9966 [12]

Answer:

im not sure but I hope this helps

Explanation:

I believe the equivalents is just the moles reactant/moles limiting reactant

water has a denisty of 1 g/mL. 1 L is 1000 ml so there are 1000g/L.

the molar mass of water is 18g/mol if you use the Liters in the equation above you can find the number of grams present. divide this number you found by 18 to find the moles.

now take the amount of the other reactant given and divide it by its own molar mass. this will give you the number of moles of that reactant.

divide the moles of water by the moles of the reactant and that is the equivalent.

to find the normality you take this number and divide it by the number of liters.
