Answer : Molecular compounds dissolve in water by means of dipole-dipole attractions and hydrogen bond attractions. These attractions between the molecular compound and water don't form ions when a molecular compound dissolves.
Explanation: I hoped that helped,
Answer:
a) will react with water: K
b) will react with steam or acid, but not water: Cr & Sn
d) will not react with water, steam, or acid: Cu
Explanation:
K reacts violently with water.
Cr will react with steam to form an oxide + H gas and will react with most acids
Sn will react with steam to form SnO₂ + H gas and, though it does not react as rapidly as other metals in acid, it dissolves easily in concentrated acids
Cu is an extremely nonreactive metal, which is what makes it so suitable for wiring
Answer:
C.) 2,1,2
Explanation:
You have to balance the equation by getting the number of elements on the left and right side to equal. Before balancing there is one more oxygen on the left side than the right side. You have to change the coefficient in front of H2O to fix this, and that means adding a "2" in front of the H2 to get that to equal as well.
You end up with 2H₂+10₂→ 2H₂O
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
B) Water only dissolves other non-polar molecules.
<em>This option is wrong because water is a polar molecule and it can dissolve only other polar molecules.</em>
