The pattern recognition is the advantage of human having evolved in order to survive. Each stage of pattern recognition introduces various of both internal and external noise which makes accuracy difficulties and it is exponentially increasing as you move down the chain. As pointed out signal detection theory can never be perfect and must be traded off between missing pattern and .
Answer: 17.9 joules
Explanation:
The quantity of Heat Energy (Q) required to heat solid silver depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Given that,
Q = ?
Mass= 3.02g
C = 0.24J/g°C
Φ = (Final temperature - Initial temperature)
= 47°C - 22.3°C = 24.7°C
Then, Q = MCΦ
Q = 3.02g x 0.240J/g°C x 24.7°C
Q = 17.9 Joules
Thus, 17.9 joules of heat isrequired.
Answer:
Explanation:
Equation of the reaction:
NaOH + HCl --> NaCl + H2O
Volume of HCl = 5 ml
Molar concentration = 1 M
Number of moles = molar concentration * volume
= 1 * 0.005
= 0.005 mol of HCl
By stoichiometry, 1 mole of HCl completely neutralizes 1 mole of NaOH
Therefore, number of moles of NaOH = 0.005 mol
Molar mass of NaOH = 23 + 16 + 1
= 40 g/mol
NaOH --> Na+ + OH-
Mass = molar mass * number of moles
= 40 * 0.005
= 0.2 g of Na+
Hexane and 2-methylpentane. If you draw the structures out, you can see that both isomers have 6 carbon atoms and 14 hydrogen atoms. Hence they have the same molecular formula but a different structural formula. I suggest drawing the compounds out for these types of questions to visualise it.
