Answer:
In our Sun, as in other stars, roughly 99.9% or so of all light emitted is emitted in a thin layer known as the photosphere, or light sphere. This is explained as follows. Interior to the photosphere the gas is ever denser and becomes far too opaque for any photon to emerge directly from that layer.

Answer:
Explanation:
a) The forward reaction is exothermic, hence when temperature is increased the equilibrium shift towards the reactants side to get rid of the excess energy. This will mean that more reactants are produced decreasing yield
b) There are a fewer number of moles of gas on the right side compared to the left side (Just count the coefficients before each compound) so a higher pressure will mean that the equilibrium will shift towards the products side in order to decrease the pressure. This will mean that more products are formed increasing yield
c) When something is powdered it's surface area to volume ratio increases. A higher surface area means that the particles around it have more area to work on so the frequency of collisions will increase increasing the rate of reaction. This is why iron is powdered.
A nuclear reaction<span> in which two or more atomic nuclei come very close and then collide at a very high speed and join to form a new type of atomic nucleus.

Cytokinesis
Explanation:
This is the answer and I am killing time because the minimum is 20 characters...good day
The number of grams of Cl2 formed when 0.115 moles of HCl react with O2 is calculated as follows
write the chemical equation
4HCl + O2 -----> 2H2O + 2Cl2
if 0.115 moles of HCl reacted and from the equation above the reacting ratio between HCl and Cl2 is 4:2 therefore the moles of Cl2= 0.115 x2/4=0.0575moles
mass of Cl2= moles x molar mass of Cl2(35.5 x2=71g/mol)
=0.0575 moles x71g/mol = 4.0825 grams
