Answer:

the passage of genetic instructions from one generation to the next generation.

These are called genes. One mate reporduces with another made and the genetic buildup merges 50 % and 50% with genetics(if it's meiosis), or DNA codes from the parents to the offspring that then possess some of the genes. That shows heridity.

Calculate the specific heat in J/(g·ºC) of an unknown substance if a 2.50-g sample releases 12.0 cal as its temperature changes

Degger [83]

Answer:

$\fbox{c = - 4.01 \: joule/g°C}$

Step by step explanation:

Given:

Mass of given sample (m) = 2.50 g

Initial temperature (T1) = 25°C

Final temperature (T2) = 20°C

Heat Energy Q = 12 cal

To find:

 $Specific \: Heat \: c = \: ?$ 

Solution:

We know that,

Specific heat of any substance is directly proportional to the mass and change in temperature.

Represented by equation,

$Q = mc \triangle T$

Where,

Q = Heat Energy

m = mass of given sample

c = specific heat

∆T = change in temperature

Substituting corresponding values,

$Q = mc \triangle T \\ 12 = 2.5\times c \times (20-25) \\ c = \frac{12}{2.5 \times ( - 5)} \\ c = - 0.96 \: cal/g°C \\$

We also know that,

$1 \: cal = 4.184 \: joules$

multiplying above answer by 4.184,

$c = - 0.96 \times 4.184 \\ \fbox{c = - 4.01 \: joule/g°C}$

Explain the geometry of PCl5 molecule and account for its high reactivity

Nesterboy [21]

Answer:

In PCl5, in addition to equitorial bonds which lie in the same plane ,there are axial bonds. Since it suffers more repulsion it is longer than the other bonds. Also these are weak bondsand therefore these bonds can break easily . Because of these reasons,PCl5 is very reactive.
