Answer:
Are memories stored in just one part of the brain, or are they stored in many different parts of the brain? Karl Lashley began exploring this problem, about 100 years ago, by making lesions in the brains of animals such as rats and monkeys. He was searching for evidence of the engram: the group of neurons that serve as the “physical representation of memory” (Josselyn, 2010). First, Lashley (1950) trained rats to find their way through a maze. Then, he used the tools available at the time—in this case a soldering iron—to create lesions in the rats’ brains, specifically in the cerebral cortex. He did this because he was trying to erase the engram, or the original memory trace that the rats had of the maze.
Lashley did not find evidence of the engram, and the rats were still able to find their way through the maze, regardless of the size or location of the lesion. Based on his creation of lesions and the animals’ reaction, he formulated the equipotentiality hypothesis: if part of one area of the brain involved in memory is damaged, another part of the same area can take over that memory function (Lashley, 1950). Although Lashley’s early work did not confirm the existence of the engram, modern psychologists are making progress locating it. Eric Kandel, for example, spent decades working on the synapse, the basic structure of the brain, and its role in controlling the flow of information through neural circuits needed to store memories (Mayford, Siegelbaum, & Kandel, 2012).
Many scientists believe that the entire brain is involved with memory. However, since Lashley’s research, other scientists have been able to look more closely at the brain and memory. They have argued that memory is located in specific parts of the brain, and specific neurons can be recognized for their involvement in forming memories. The main parts of the brain involved with memory are the amygdala, the hippocampus, the cerebellum, and the prefrontal cortex

A 26.0 g sample of HCl is dissolved using 1.00 L of water. Calculate the
molarity of this solution. (HCI molar mass: 36.0 g/mol)
Answers
Answer:
[tex]\boxed {\boxed {\sf molarity \approx 0.722 \ M \ HCl}}[/tex]
Explanation:
Molarity is the concentration measurement equal to moles per liter.
[tex]molarity=\frac{moles}{liters}[/tex]
We have 26.0 grams of HCl and 1.00 liters of water. We must convert grams of HCl to moles.
To convert from grams to moles, the molar mass is used. Usually we find these values on the Periodic Table, but they are already provided. The molar mass of hydrochloric acid is 36.0 grams per mole. Use this number as a ratio.
[tex]\frac {36.0 \ g \ HCl}{ 1 \ mol \ HCl}[/tex]
Multiply by the given number of grams: 26.0
[tex]26.0 \ g \ HCl *\frac {36.0 \ g \ HCl}{ 1 \ mol \ HCl}[/tex]
Flip the ratio so the grams of hydrochloric acid cancel.
[tex]26.0 \ g \ HCl *\frac {1 \ mol \ HCl}{ 36.0 \ g \ HCl}[/tex]
[tex]26.0 *\frac {1 \ mol \ HCl}{ 36.0 }[/tex]
[tex]\frac {26.0}{ 36.0 } \ mol \ HCl = 0.72222222222 \ mol \ HCl[/tex]
Now we know the moles and liters.
0.72222222222 mol HCl 1.00 LSubstitute these values into the molarity formula.
[tex]molarity = \frac {0.72222222222 \ mol \ HCl}{1.00 \ L }[/tex]
[tex]molarity = 0.72222222222 \ mol \ HCl/L[/tex]
The original measurements of grams and liters have 3 significant figures, so our answer must have the same. For the number we calculated, that is the thousandth place.
0.72222222222The 2 tells us to leave the 2 in the thousandth place.
[tex]molarity \approx 0.722 \ mol \ HCl/ L[/tex]
1 mole per liter is equal to 1 molar, or M. Change the units.
[tex]molarity \approx 0.722 \ M \ HCl[/tex]
The molarity of this solution is approximately 0.722 M HCl
How many flourine atoms are present in 5.3 grams of flourine sample? (note that you have to use the 3 step method)
Answers
Answer:
1.7x10²³ Fluorine atoms are present
Explanation:
To solve this question we must know that, to find the amount of atoms of a substance from its mass, we have, as first, to convert this mass to moles using molar mass of the substance. With the moles we can find the amount of molecules using Avogadro's number. And with the formula we can know the atoms presents:
Moles Fluorine (F₂, Molar mass: 37.997g/mol)
5.3g * (1mol / 37.997g) = 0.139 moles F₂
Molecules F₂:
0.139 moles F₂ * (6.022x10²³molecules / mol) = 8.4x10²² molecules F₂
As 1 molecule of F₂ contains 2 atoms of Fluorine:
8.4x10²² molecules F₂ * 2 =

radioactive decay?
Answers
Answer:
C
Explanation:
The amount of energy in radio active decay will be released 2.25 × [tex]10^{17}[/tex]J.
What is radioactive decay?The process of radioactive decay is the loss of energy through radiation from an unstable atomic nucleus. The term "radioactive" refers to a substance that contains unstable nuclei.
Calculation of energy which released in radioactive decay.
Given data:
M = 0.025 kg
E = ?
Energy of the radioactive decay can be determined by using the formula:
E= m[tex]c^{2}[/tex]
where, E is energy , m is mass and c is speed of light.
Put the value of given data in above equation.
E = (0.025) ×(3×[tex]10^{8}[/tex])∧2J
E = 0.025 × 9 × [tex]10^{18}[/tex].J
E = 0.225 × [tex]10^{18}[/tex].J
E= 2.25 × [tex]10^{17}[/tex]J
Therefore, The amount of energy in radio active decay will be released 2.25 × [tex]10^{17}[/tex]J.

Explanation:
Step 1: Given data
Initial amount of methane (ni): 8.0 molFinal amount of methane (nf): 0 mol (it reacts completely)Volume of the container (V): 2.00 LTime elapsed (t): 3.2 sStep 2: Calculate the average rate of consumption of methane
Methane burns in excess oxygen according to the following equation.}

We can calculate the average rate of consumption of methane (r) using the following expression.
r = - Δn/V × t = - (nf- ni) / V × t
r = - (0 mol - 8.0 mol) / 2.00 L × 3.2 s = 1.3 M/s

How many grams of CaCl2 should be dissolved in 445.2 mL of water to make a 0.19 M solution of CaCl2?
Answers
In order to solve this, you will need to know how many moles of CaCl2 you will need, and to do so, you must look at the concentration of the solution.
You are told that the concentration of the solution is 0.19M, meaning that there is 0.19 moles of CaCl2 for every 1 liter of solution. However, you don't have 1 liter of solution, you have 445.2 mL. You must convert this to liters by dividing by 1000.
445.2 mL * (1 L / 1000 mL) = 0.4452 L
Now, you can solve for how many moles the solution must have. Since M = mol / L and you are given M and L, you can set up an equality as follows:
0.19M = mol / 0.4452 L
Now, in order to find the number of moles, you multiply both sides by 0.4452L
0.19M * 0.4452 L = moles = 0.084588mol
Now, you must calculate the molar mass of CaCl2 by using the periodic table
MM Ca = 40.078 g/mol
MM Cl = 35.452 g/mol
40.078 + (35.452 * 2) = 110.982 g/mol
Now you multiply the number of moles in the solution you calculated by the molar mass.
0.084588mol * 110.982 g/mol = 9.387 g CaCl2

A sample of gas with a volume of 5.0 m3 at a temperature of 298 K and a pressure of 0.84 atmospheres is left in a closed container where the temperature increases to 323 K and the pressure increases to 0.89 atmospheres. What is the new volume of a gas sample?
Answers
Answer:
5.12 m³
Explanation:
Using the combined gas law formula as follows:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (m³)
V2 = final volume (m³)
T1 = initial temperature (K)
T2 = final temperature (K)
According to this question;
V1 = 5.0 m³
V2 = ?
P1 = 0.84 atm
P2 = 0.89 atm
T1 = 298 K
T2 = 323 K
Using
P1V1/T1 = P2V2/T2
0.84 × 5/298 = 0.89 × V2/323
4.2/298 = 0.89V2/323
Cross multiply
4.2 × 323 = 298 × 0.89V2
1356.6 = 265.22V2
V2 = 1356.6 ÷ 265.22
V2 = 5.12 m³

how much heat is required to increase the temperature of 20 grams of water by 26 degrees celsius?
Answers
Answer: 2175.68 J heat is required to increase the temperature of 20 grams of water by 26 degrees celsius.
Explanation:
Given: Mass = 20 g
Change in temperature = [tex]26^{o}C[/tex]
The standard value of specific heat of water is [tex]4.184 J/ g^{o}C[/tex]
Formula used to calculate the heat energy is as follows.
[tex]q = m \times C \times \Delta T[/tex]
where,
q = heat energy
m = mass of substance
C = specific heat of substance
[tex]\Delta T[/tex] = change in temperature
Substitute the values into above formula as follows.
[tex]q = m \times C \times \Delta T\\= 20 g \times 4.184 J/g ^{o}C \times 26^{o}C\\= 2175.68 J[/tex]
Thus, we can conclude that 2175.68 J heat is required to increase the temperature of 20 grams of water by 26 degrees celsius.
