Particle E is an atom because on the periodic table the number of protons is the same exact number of electrons and the number of neutrons cannot exceed one because protons and neutrons add up to give electrons
Answer:
1) False
2) there are equal amounts of rectants and products
Explanation:
1) When dynamic equilibrium is achieved. the rate of forward and backward reaction they are the same, that is to say, two opposite reactions occur at the same rate, keeping the concentrations constant over time. Different to say the rate of the ractions go to zero.
2) A chemical equilibium exists when what is produce in quantities is equal to what reacts.
So the correct answer is the literal (d).
A gland is an organ that excretes chemical fluids to discharge into the surroundings or for use in the body.
0.3 moles of lithium chloride (LiCI) reacted to produce 24.68 grams of lithium nitrate (LiNO3).
Explanation:
Balanced equation for the reaction is:
2LiCl + Pb(NO3)2 ⇒2 LiNO3 + PbCl2
Data given:
mass of LiNO3 produced = 24.68 grams
moles of LiCl reacted= ?
atomic mass of 1 mole of LiNO3 = 68.946 Grams
Number of moles = 
putting the values in the above equation:
= 0.3 moles
from the reaction,
2 moles of LiCl reacted to form 2 moles of LiNO3
so, x moles of LiCl reacted to form 0.3 moles of LiNO3
= 
x = 0.3 moles of LiCl will react to form 0.3 moles of LiNO3.
The theoretical probability of rolling a two will be 1 in 6 or 1/6 since there is only 1 successful event in 6 possible outcomes when you roll a cube or a dice. When you perform experiments to determine the experimental probability of rolling a two, it will not be the same as that of the theoretical probability not unless you perform the experiment infinite times.
