The answer is 3/2 the original pressure. The concept behind this is the ideal gas law wherein it states that Pressure (P) times volume(V) is equal to number of moles (n) times ideal gas constant (R ) times temperature (T). Since you’re trying to calculate for the pressure you use P=nRT/V. Input 3 to Temperature and 2 to volume. You’ll get a pressure of 3/2 which is 3/2 times the original pressure.
The nucleus of an atom is positively charged and the electrons are negatively charged therefore, the nucleus of an atom attracts the electrons around it and this nature is called nuclear charge.
Each electron in an atom experiences two kinds of force one is an attraction to the nucleus and another is repulsion from other electrons. The presence of many electrons makes more repulsive force and this decreases the nuclear attraction.
The amount of nuclear charge is the positive charge experienced by an electron that is present in a multi-electron atom. The attractive interaction between the nucleus of an atom and electrons of the same atom increases with the increase of positive charge (+Ze) on the nucleus.
This attraction for the valence electrons will be lower because of the Shielding of inner shell electrons. Due to the shielding of inner-shell electrons, the valence electrons will not experience the positive charge of the nucleus entirely while electrons close to the nucleus feel maximum attraction and have the lowest energy.

Answer:
I think it will start to have a greenish color and get lighter
Explanation:
b. bauxite
c. iron
d. timber
All the following are examples of minerals, except timber.
The correct option is d, timber.
Minerals are solid chemical compounds that have fixed or definite chemical compositions.
Some minerals are calcium, phosphorus, bauxite, iron etc.
Our body needs a very little amount of minerals for the boy's growth.
Timber is wood, which is not a mineral.
Thus, the correct option is d. timber.

Answer: D. Timber
Explanation:
Na2SO4
Na(SO4)2
NaSO8
Answer:
The correct answer is .
Explanation:
Given polyatomic ions:
1) Sulfate =
2) Phosphate =
3) Hydroxide =
The formula of Sodium sulfate will be:
Sodium carries 1+ charge and and sulfate ion carries 2-charge. In order to neutralize negative charge on sulfate ion two sodium ions will be needed.
