Answer:
Cl has a smaller radius than Cl− because Cl− has an expanded electron cloud.
Explanation:
Definition of atomic radii:
The atomic radius is the distance between center of two bonded atoms.
Trend along period:
As we move from left to right across the periodic table the number of valance electrons in an atom increase.The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases.
Trend along group:
In group by addition of electron atomic radii increase from top to bottom due to increase in atomic number and addition of extra shell.
In this way Cl⁻ will have the largest atomic radii because one extra electron is added and electronic cloud more expanded as compared to neutral atom.

Answer:
6.2192 meters
Explanation:
5.98cm × 104cm= 621.92cm
100 cm makes 1 meter therefore
621.92 ÷100= 6.2192m
Answer:
mass of carbon dioxide produced = 87.9153846154 g ≈ 87.92 g
Explanation:
The chemical equation is as follow
Butane = C4H10
oxygen = O2
carbon dioxide = CO2
water = H2O
C4H10 + O2 → CO2 + H2O
The equation should be balanced before solving it.
2C4H10 + 13O2 → 8CO2 + 10H2O
molar mass of 13 mole of oxygen = 416 g
molar mass of 8 mole of carbon dioxide = 256 + 96 = 352 g
416 g of oxygen was needed to produce 352 g of carbon dioxide
103.9 g will produce ?
cross multiply
mass of carbon dioxide produced = 103.9 × 352/416
mass of carbon dioxide produced = 103.9 × 352/416
mass of carbon dioxide produced = 36572.8
/416
mass of carbon dioxide produced = 87.9153846154 g ≈ 87.92 g
Answer:
A dichotomous key is a tool that allows the user to determine the identity of items and organisms in the natural world. ... In each step, the user is presented with two statements based on characteristics of the organism. If the user makes the correct choice every time, the name of the organism will be revealed at the end
