Answer:
Moon rocks contain few volatile substances (e.g. water), which implies extra baking of the lunar surface relative to that of Earth. The relative abundance of oxygen isotopes on Earth and on the Moon are identical, which suggests that the Earth and Moon formed at the same distance from the Sun.
Explanation:
Answer:
A)Trial 1 because the average rate of reaction is lower.
Explanation:
I accidentally gave myself low rating my bad
According to Versatile Carbon - ChemEd DL Carbon is found in many different chemical compounds, including those found in space. Carbon is versatile because it can form single, double, and triple bonds. It can also form chains, branched chains, and rings when connected to other carbon atoms.
The volume of a gas at STP is 45.6L in the given conditions.
<h3>How to calculate the volume of the gas at given conditions?</h3>
This is an example of a combined gas law equation.
P₁V₁/T₁=P₂V₂/T₂
V₂=V₁×P₁/P₂×T₂/T₁
Convert STP in bar
P₁=1atm=1.013 bar, V₁=50L, T₁=303K, P₂=1bar, V₂=?, T₂=273K
V₂=50×1.013/1×273/303
V2=45.6L

Answer:
The relation between the shielding and effective nuclear charge is given as
where s denote shielding
z_{eff} denote effective nuclear charge
Z - atomic number
Explanation:
shielding is referred to as the repulsion of an outermost electron to the pull of electron from valence shell. Higher the electron in valence shell higher will be the shielding effects.
Effective nuclear charge is the amount of net positive charge that valence electron has.
The relation between the shielding and the effective nuclear charge is given as
wheres denote shielding
z_{eff} denote effective nuclear charge
Z - atomic number
