Answer:
C
Explanation:
Because how would you know what the reaction rate is and how it is affected by the concentrations
Answer:
a. c= silver/ 234J(kg/K) > b. c= water/ 4190 J(kg/K) > c. c= glass/ 754J/(kg.K)
Explanation:
Hello.
In this case, since the heat resulting from the temperature change for an specified amount of a substance is defined via:
Since the specific heat is related to amount of energy required to raise the temperature of 1 kg of a substance by 1 °C, we can infer that the higher the specific heat, the higher the required energy as they are in a directly proportional relationship. Moreover, since the specific heat and the change in temperature are in an inversely proportional relationship, we can infer that the higher the specific heat, the lower the temperature change, therefore, we can rank the substances follows:
a. c= silver/ 234J(kg/K) > b. c= water/ 4190 J(kg/K) > c. c= glass/ 754J/(kg.K)
It means that silver will produce the largest temperature change, next water and finally glass since silver has the smallest specific heat next water and finally glass.
Best regards.
Answer:
medium in which it is traveling
Explanation:
i hope it helps u
The moles of OH- ions from the Ba(OH)2 must equal the moles of H+ ions from the HNO3 in order for them to neutralize. You must multiply volume (in liters) by the molar to get number of moles. There is 0.90 molar of OH- because there is twice as many OH- as there is Ba(OH)2. The molarity of H+ is unknown.
Let X be the unknown molarity
(0.0182 L)(0.90 M) = (0.0385 L)(X M)
X = 0.43 M (2 significant figures)
So the molarity of H+ ions, and therefore HNO3 is 0.43 M
