Division (asexual) method, and the sexual method of reproduction where two organisms produce an offspring. The sexual reproduction requires the interaction of two organisms; gametes, typically a fertilization. The offspring consists of characteristics derived from both of the parental organisms.
Answer:
(a) The equilibrium partial pressure of BrCl (g) will be greater than 2.00 atm.
Explanation:
Q is the coefficient of the reaction and is calculated the same of the way of the equilibrium constant, but using the concentrations or partial pressures in any moment of the reaction, so, for the reaction given:
Q = (pBrCl)²/(pBr₂*pCl₂)
Q = 2²/(1x1)
Q = 4
As Q < Kp, the reaction didn't reach the equilibrium, and the value must increase. As we can notice by the equation, Q is directly proportional to the partial pressure of BrCl, so it must increase, and be greater than 2.00 atm in the equilibrium.
The partial pressures of Br₂ and Cl₂ must decrease, so they will be smaller than 1.00 atm. And the total pressure must not change because of the stoichiometry of the reaction: there are 2 moles of the gas reactants for 2 moles of the gas products.
Because is a reversible reaction, it will not go to completion, it will reach an equilibrium, and as discussed above, the partial pressures will change.
An example of an allotrope is carbon:
Carbon can exist in graphite, diamond and amorphous

Answer:
Here's what I get
Explanation:
i. E = mc²
E = energy
m = mass
c = the speed of light
"Energy equals mass times the square of the speed of light.”
The equation says that energy and mass are interchangeable. If you multiply the mass of an object by c², you get its equivalent and of energy.
The SI base units for energy are kg·m²s⁻².
The most common derived unit is the joule (J). Others are the newton-metre (N·m), kilowatt-hour (kWh), watt-second (W·s), and volt-coulomb (V·C).
ii. Nuclear vs chemical reactions
a. Alpha decay
A nuclear reaction — like α decay — takes place in the nucleus of an atom.
An element becomes a different element.
b. Chemical reaction
Na· + ·Cl ⟶ Na⁺ + Cl⁻
A chemical reaction — like the formation of NaCl — involves rearranging the electrons, which are outside the nucleus.
The elements do not change.
Salt still consists of sodium and chlorine.
