Answer:
3.5 mL
Explanation:
Let us represent lauric acid with the symbol LaCOOH and the anion as LaCOO-. The reaction between the anion and H2SO4 is;
LaCOO-(aq) + H2SO4(aq) -----> LaCOOH(aq) + HSO4-(aq)
Number of moles of LaCOO- = 2.75 g/200 g/mol = 0.014 moles
Since the mole ratio of the reaction is 1:1, then the amount of H2SO4 required is also 0.014 moles
Then;
n = CV
n = number of moles
C= concentration
V = volume
V = n/C
V = 0.014 moles/4.0 M
V= 3.5 * 10^-3 L
V = 3.5 mL
Answer:
True
Explanation:
Technology has been mans best friend for a while due to the fact that they can make things to help others and create more jobs and help everyone overall.
Answer: self defense
Explanation: there either scared or feel evil presence so they either attack or escape
The predator hunts the prey. The predator needs the prey to survive because this is the predator's source of food. The prey needs the predator to help reduce population, this is because when the population of prey grows too large more resources need to be consumed. If the prey start dying the predators lose their food source. If the predators start dying the prey's population will become so high that it depletes their resources, such as food.
Answer:
1s2 2s2 2p6 3s2 3p6 4s2
shorthand: [Ar] 4s2
Explanation:
the end number values are exponents, so 1s^2
