Answer:
r = 3.61x M/s
Explanation:
The rate of disappearance (r) is given by the multiplication of the concentrations of the reagents, each one raised of the coefficient of the reaction.
r = k.
K is the constant of the reaction, and doesn't depends on the concentrations. First, let's find the coefficients x and y. Let's use the first and the second experiments, and lets divide 1º by 2º :
x = 1
Now, to find the coefficient y let's do the same for the experiments 1 and 3:
y = 1
Now, we need to calculate the constant k in whatever experiment. Using the first :
k = 4.01x10^{-3} M^{-1}s^{-1}[/tex]
Using the data given,
r =
r = 3.61x M/s
Answer: Acidic liquids have low pH levels. Many fruit juices qualify as acidic liquids. Some of the more acidic fruit juices are orange juice, lemon juice, grapefruit juice, tomato juice and red currant juice.
Explanation:
When lights hits an object, the light either get absorbed, reflected or refracted
Data:
V1 (initial volume) = 233 mL
P1 (initial pressure) = 622 kPa
V2 (final volume) = ? (mL)
P2 (final pressure) = 988 kPa
Formula:
P1 * V1 = P2 * V2
Solving:
P1 * V1 = P2 * V2
622 * 233 = 988 * V2
114926 = 988 V2
988 V2 = 114926
Answer:
a. Synthesis reaction
b. Single - Displacement
c. Decomposition reaction
d. Combustion Reaction
Explanation:
Synthesis reaction: Reaction in which two or more substance combine to give a single compound.
Single - Displacement : Reaction in which the more reactive element displaces the less reactive element.Here Li replace OH from water.
Decomposition reaction: Reaction in which a single reactant decompose to give two or more products.
Combustion Reaction : IT is a redox reaction in which a substance is burned in the presence of oxygen to give carbon dioxide and water.
