Answer: C
Explanation:
In endothermic reactions, enthalpy is positive, and in exothermic reactions, enthalpy is negative, So, if enthalpy is positive, then it is an endothermic reaction, and hence is required for the reaction to occur.
Sorry, I'm late, but the answers are:
Metals are malleable
Metals are ductile
Metals ARE good heat and electricity conductors
Metals lose electrons in reactions
Answer:
See below.
Explanation:
I'll do the second row for you the other 2 are done in exactly te same way.
B. Area of 1 side of cube = 2*2 = 4.
Surface area = 4*6 = 24
Volume = 2*2*2 = 8.
Surface area / volume = 24/8 = 3.
Ratio of Suface Area to Volume = 24 : 8 = 3 : 1. (divide both by 8)
Explanation:
Sodium hydroxide completely ionizes in water to produce sodium ions and hydroxide ions. Hydroxide ions are in excess and neutralize all acetic acid added by the following ionic equation:
The mixture would contain
if undergoes no hydrolysis; the solution is of volume after the mixing. The two species would thus be of concentration and , respectively.
Construct a RICE table for the hydrolysis of under a basic aqueous environment (with a negligible hydronium concentration.)
The question supplied the <em>acid</em> dissociation constant for acetic acid ; however, calculating the hydrolysis equilibrium taking place in this basic mixture requires the <em>base</em> dissociation constant for its conjugate base, . The following relationship relates the two quantities:
... where the water self-ionization constant under standard conditions. Thus . By the definition of :
Answer:
I don't think so, it will just go slower because the ocean is denser
