Answer:
Cu(s) + 4HNO₃(aq) -> Cu(NO₃)₂(aq) + 2NO₂(g) + 2H₂O(l)
Answer:
B
Explanation:
Molarity measures the strength of a solution. Remember, a solution is made up of two parts: the solvent (which does the dissolving) and the solute (the substance that is dissolved). The more solute there is, the higher the concentrate and therefore the higher the molarity of the solution. Thus B is the answer
Answer:
troposphere
stratosphere
mesosphere
thermospjere
exosphere
Explanation:
this is from the lowest to highest
C. 2
2H_2O + <u>2e</u>^(-) → H_2 + 2OH^(-)
2Cl^(-) → Cl_2 + <u>2e</u>^(-)
2H_2O +Cl^(-) + <u>2e</u>^(-) → H_2 + Cl_2 + 2OH^(-) + 2e^(-)
2H_2O +2Cl^(-) → H_2 + Cl_2 + 2OH^(-)
This is a <em>redox reaction</em> in which two chloride ions transfer two electrons to two molecules of water.
