Sally is struggling with Prospective memory.
<u>Explanation:</u>
The type of memory in which an individual has problem to remember a planned set of actions. He or she can remember or recall it only after some period of time may be in future and not at that time where those actions needs to be performed. These type of memory problem can range from a simple situation like the tasks that are to be done in common, simple and daily basis to serious issue.
Some of the instances of this kind of prospective memory includes, closing a tap after usage, cut a call over phone when the conversation is done,etc. These instances includes only simple issues. Some of dangerous issues includes forgetting to take regular medicines, forgetting to take some protective and safety measures while driving,etc.
Answer:
2.0 x 10⁻³ M/s.
Explanation:
- The rate of the reaction is the change of the concentration of the reactants or the products with time.
<em>The rate of the reaction = - Δ[reactants]/Δt = - [(0.6 M - 1.8 M)]/(580 s - 0 s) = 2.069 x 10⁻³ M/s.</em>
Answer:
The mass of board is 1.52 g.
Explanation:
Given data:
Density of wood = 0.487 g/cm³
Length of board = 3.21 cm
Width of board = 12.2 cm
Height of board = 0.80 mm (0.80/10=0.08 cm)
Mass of board = ?
Solution:
We know that density of an object is equal to the mass of substance divided by its volume. So we can calculate the mass from density formula.
Formula:
D = m/v
d = density
m = mass
v = volume
Now we will calculate the volume first.
V = length × width × height
V = 3.21 cm × 12.2 cm × 0.08 cm
V = 3.13cm³
Now we will calculate the mass.
D = m/v
0.487 g/cm³ = m/ 3.13 cm³
m = 0.487 g/cm³ × 3.13 cm³
m = 1.52 g
The mass of board is 1.52 g.
Answer:1)1.99 M
Explanation:
Molarity is given as = moles solute/Liter solution
The solute which is LiOH is already given in moles as 1.495 moles
Given that solution is 750 mL, we convert to liters.
Liters of the solution= mL of the solution x (1 L/1000 mL)
750 mL x (1 L/1000 mL)
0.75 L
Molarity = moles solute/Liter solution
Molarity = 1.495 moles of LiOH/0.75 L of solution
Molarity = 1.99M
The molarity of this solution is 1.99M (moles per liter).
