Which of the following ions has the largest radius? Br- S2- B3+ Mg2+ Li+
iren [92.7K]

Answer:

Br - has the largest radius

Explanation:

These ions each have achieved the nearest noble gas configuration. Br - has a like electron configuration to that of Krypton, S2- has a like electron configuration to that of Argon,  B3+ to Helium, Mg2+ to Neon, and Li+ to Helium.

_______________________________________________________

Traveling down a group, the radius tends to increase as atom gains another shell. Here we are comparing elements of like electron configuration to the noble gases Helium, Neon, Argon, Krypton. Krypton, being the last element present in the group out of the 4, has the greatest radius as it has the most shells. Thus, Br - has the largest radius.

A force of 100 newtons was necessary to lift a tree. A total of 50 joules of work was done. How far was the tree lifted
defon

Answer:

Distance lift the tree = 0.5 m

Explanation:

Given:

Work done = 50 joules

Force = 100 newton

Find:

Distance lift the tree

Computation:

Distance = Work done / Force

Distance = 50 / 100

Distance = 0.5 m

Distance lift the tree = 0.5 m

Carmel forms when table sugar c12h22o11, reacts with oxygen. what elements make up carmel
Natasha_Volkova [10]
The reaction of sugar with oxygen is as follows:

C₁₂H₂₂O₁₁ + 12 O₂ → 12 CO₂ + 11 H₂O

When in the presence of pure oxygen, sucrose (table sugar) will not form caramel, in fact it will combust into carbon dioxide and water like any other carbohydrate.

Caramel is actually formed by slowly heating sucrose to high temperatures of around 170 °C resulting in thermal decomposition. This essentially removes molecules of water from the sucrose which results in the compound isomerizing and eventually polymerizing to form caramel. The chemical make up of caramel is the same as sucrose, so it will still be composed of carbon, hydrogen and oxygen.
