Explanation:
A solute is a material that dissolves when it comes into contact with another substance. The spices are the solute in this situation.
Explanation:
Mercury is the only element that is liquid at room temperature.
Explanation:
Oxygen makes up about 47% of the Earth’s mass, followed by Silicon at 28%, Aluminum at 8%, Iron at 5%, Calcium at 4%, and Sodium and Potassium, each at 3%.
Explanation:
Hydrogen is the most abundant element in the universe, followed by Helium and then Oxygen.
Explanation:
The number of dots in a Lewis-dot structure model corresponds to the number of valance electrons for that atom. Because carbon has four valance electrons, it’s Lewis-dot structure model would have 4 dots.
Explanation:
Viscosity, or the resistance of a fluid against force, increases with a temperature decrease, that is, fluid becomes more viscous (flows slower) in colder temperatures.
Explanation:
Blue litmus paper turns red in the presence of an acid. Ammonia, lye, and detergent are basic, so they would not give off Hydrogen ions in an aqueous solution and when added to blue litmus paper the paper would remain blue.
Explanation:
A saturated solution is one that has the maximum amount of solvent dissolved into it.
Explanation:
Metals are generally solids at ambient temperature, whereas nonmetals are usually gaseous.
Explanation:
Gas particles exert little to no force on each other, so they “bounce” off each other when they collide. The other options are all false regarding gas particles.
Explanation:
Dihydrogen monoxide, or H2O, is more commonly known as water.
Explanation:
This is the only answer choice that is not true, as the question asks.
Explanation:
Endothermic reactions absorb heat, while exothermic reactions give off heat.
Explanation:
Condensation is the reverse of vaporization and can be observed when gas cools and becomes a liquid, such as when dew appears in the morning after the temperature drops at night.
Explanation:
The pace of a chemical reaction is not affected by the quantity of mass lost since the law of conservation of mass (or matter) stipulates that there is no mass loss in a chemical reaction.
Explanation:
Because it is a combination of two elements, magnesium oxide does not appear on the periodic table.
