What does the prefrontal cortex do? What happens to grey matter in adolescence? What does this mean?

shutvik [7]

Answer:

Adolescence is a time of significant growth and development inside the teenage brain. The main change is that unused connections in the thinking and processing part of your child's brain (called the grey matter) are 'pruned' away. ... The front part of the brain, the prefrontal cortex, is remodelled last.

What is δs° for the reaction so2(s) no2(g) → so3(g) no(g)? substance s°(j/k • mol) so2(g) 248.5 so3(g) 256.2 no(g) 210.6 no2(g)

zimovet [89]

The value of ΔS° for reaction is - 22.2 J/K.mol

$SO_{2}(s)+NO_{2} (g)$ → $SO_{3}(g)+NO(g)$

Calculation,

Given value of S°(J/K.mol) for

$SO_{2}(s)$ = 248.5

$NO_{2} (g)$ = 240.5

$NO(g)$ = 210.6

$SO_{3}(g)$ = 256.2

Formula used:

ΔS° (Reaction) = ∑S°(Product) - ∑S°(Reactant)

ΔS° = (256.2 + 210.6 ) - ( 248.5 + 240.5) = 466.8 - 489 = - 22.2 J/K.mol

The change in stander entropy of reaction is - 22.2 J/K.mol. The negative sign indicates the that entropy of reaction is decreases when reactant converted into product.

anzhelika [568]

A. a wide variety of hunting techniques

Explanation:

To help the fisher population to survive in a changing environment, they have to develop a wide variety of hunting techniques.

The new fisher population have to develop a wide range of strategies to satisfy its carnivorous instincts.

Most predators are carnivores with a wide range of hunting skills
They must be fast, subtle, good sighted and well adapted body part to hunt of preys.
As they transcends different environments, they must have good and diverse hunting skills to give them a competitive advantage.

How many grams of H2S is needed to produce 18.00g of PbS if the H2S is reacted with an

goldenfox [79]

Answer:

2.56 grams of H₂S is needed to produce 18.00g of PbS if the H2S is reacted with an excess (unlimited) supply of Pb(CH₃COO)₂

Explanation:

The balanced reaction is:

Pb(CH₃COO)₂ + H₂S → 2 CH₃COOH + PbS

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction) they react and produce:

Pb(CH₃COO)₂: 1 mole
H₂S: 1 mole
CH₃COOH: 2 moles
PbS: 1 mole

In this case, to know how many grams of H₂S are needed to produce 18.00 g of PbS, it is first necessary to know the molar mass of the compounds H₂S and PbS and then to know how much it reacts by stoichiometry. Being:

H: 1 g/mole
S: 32 g/mole
Pb: 207 g/mole

The molar mass of the compounds are:

H₂S: 2* 1 g/mole + 32 g/mole= 34 g/mole
PbS: 207 g/mole + 32 g/mole= 239 g/mole

So, by stoichiometry they react and are produced:

H₂S: 1 mole* 34 g/mole= 34 g
PbS: 1 mole* 239 g/mole= 239 g

Then the following rule of three can be applied: if 239 grams of PbS are produced by stoichiometry from 34 grams of H₂S, 18 grams of PbS from how much mass of H₂S is produced?

$mass of H_{2} S=\frac{18 grams of PbS*34 grams of H_{2}S }{239 grams of PbS}$

mass of H₂S= 2.56 grams

<u><em>2.56 grams of H₂S is needed to produce 18.00g of PbS if the H2S is reacted with an excess (unlimited) supply of Pb(CH₃COO)₂</em></u>
