Roughly, Aufbau Principle says that in an atom or an ion, electrons enter the shell with low energy first before entering the shell with high energy.
An atom has shells around its nucleus. Electrons enter these shells and orbit around the nucleus of an atom. To say about the properties of these shells, the shell nearest to the nucleus has the lowest energy. The farther the shell from the nucleus, the higher its energy. Aufbau Principle states that electrons enter the closest shell to the nucleus first since it has the lowest energy. When that shell has its maximum number of electrons is can hold, then the next electron will enter the second-closest shell to the nucleus, which has higher energy than the first shell.
Answer:
Fir tree
Explanation:
Producers, Consumers, and Decomposers in the Forest Community. Producers are any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar. The plant uses this sugar, also called glucose to make many things, such as wood, leaves, roots, and bark. Rabbit, Fungus, and raccoon are all decomposers!
Answer:
615 μK/ms.
Explanation:
The conversion of 615mK/s to μK/ms can be obtained as follow:
1 mK/s = 10^-3 K/s
Therefore, 615mK/s = 615x10^-3 K/s
1K/s = 10^6 μK/s
Therefore,
615x10^-3 K/s = 615 x 10^-3 x 10^6 μK/s = 615x10^3 μK/s.
1s = 10^3ms
Therefore,
615x10^3 μK/s = 615x10^3 μK/ 10^3ms = 615 μK/ms.
Therefore,
615 mK/s = 615 μK/ms.
Answer:
put the solution over ice.
Since the Mg is in excess, therefore HCl will be fully
consumed in the reaction.
The first step is to find the amount of HCl in mol
Let N (HCl) = amount
of HCl in mol
N (HCl) = (6 mol HCL/L solution) *( 125 mL ) * (1 L/1000 mL)
= 0.75 mol of HCl
Through stoichiometry
N (H2) = 0.75 mol HCl * (1 mol H2/ 2 mol of HCl)
N(H2) = 0.375 mol H2
Since we are asked
for the number of grams of H2 (mass), we multiply this with the molar mass of hydrogen
M (H2) = 0.375 mol H2 ( 2 g H2 / 1 mol H2)
M (H2) = 0.75 g H2
