Answer:
The molarity of the acetic acid in this vinegar is 0.853 M
Explanation:
Step 1: Data given
Volume of vinegar sample = 10.00 mL
Concentration of NaOH = 0.5052 M
16.88 mL are required to neutralize the acetic acid
Step 2: The reaction
HC2H3O2(aq) + NaOH(aq) ⇔ NaC2H3O2(aq) + H2O(l)
Step 3: Calculate molarity of cetic acid (HC2H3O2)
C1*V1 = C2*V2
⇒with C1 = the molarity ofHC2H3O2= TO BE DETERMINED
⇒with V1 = the volume of HC2H3O2 = 10.00 mL = 0.01 L
⇒with C2 = the molarity of NaOH = 0.5052 M
⇒with V2 = the volume of NaOH = 16.88 mL = 0.01688L
C1 = (C2*V2)V1
C1 = (0.5052 * 0.01688 ) / 0.01
C1 = 0.853 M
The molarity of the acetic acid in this vinegar is 0.853 M
6 meters is definitely bigger
Answer:
The answer is B. The population has increased and so has demand for energy resources.
Explanation:
Fracking is a technique used to increase the extraction of gas and oil from the subsoil. It consists of extracting small dispersed concentrations of hydrocarbons (it can also be done with oil). To do this, a vertical drilling of four or five kilometers is carried out and then water mixed with chemicals is introduced to fracture the rocky substrate, filtering the fuel into the conduit. Fracking is used due to the scarcity of resources and the reduction of reserves. So, while the population continues to increase, the demand for energy also increases. This leads to fracking being used to meet the high demand.
