Yes, (NH4)2SO4 and ALL other ammonium salts are soluble, (and all sulfates from single-positive ions are as well).
nh4cl will dissociate in water to form nh4(+) and cl(-)
Yes
no
YES it is
Water is the solvent, and sugar is the solute.
... The solute is sugar or the tea mix, the solvent is the water.
Because it is an intermediate polar-nonpolar solvent
Water is the solvent and chalk is the solute.
The solvent is water, the solute is carbon dioxide.
The solvent is water. The solute is carbon dioxide, plus maybe a bit of salt.
the non polar solute gets dissolved as non polar solutes tend to dissolve in non polar solvents than in polar solvents. for eg: benzene(non polar solute) gets dissolved in carbon tetrachloride which is a non polar solvent but not in water because it is a polar solvent.
Because NaCl is a polar compound (solute) dissolved in a polar solvent (water).
"Salt water" is a solution because the water is the solvent and the salt is the solute. Salts dissolve readily in water because they're ionic, and therefore very polar. Water is polar as well, and tears the salt apart into its constituent ions.
Water is a polar solvent and can dissolve a polar solute; this is not an absolute rule but it is very close to truth.
Water is the solvent, and sugar is the solute.
The sugar is the solute and the water is the solvent. Whatever is dissolved is the solute, and whatever the solute is dissolved in is the solvent. The solvent dissolves the solute.
... The solute is sugar or the tea mix, the solvent is the water.
Because it is an intermediate polar-nonpolar solvent
Water is the solvent and chalk is the solute.
something that is non-soluble in whatever solvent youre using the solvent is what is doing the dissolving, while the solute is the thing being dissolved for example: a mixture of water and salt. water is the solvent and salt is the solute. but to answer your question in more depth, the solubility of something is determined by its polarity compared to the polarity of the solvent water is polar, so polar molecules dissolve readily in water if the substance is known to be nonpolar, then it wont dissolve in water (im just assuming your solvent is water. if you want a more specific example, you should check the polarity of your solvent and solute.)
The solvent is water, the solute is carbon dioxide.
