Rubidium and cesium have similar chemical

yawa3891 [41]

Rubidium and cesium have similar chemical properties because in the ground state the atoms of both elements each have one electron in the outermost shell. The correct option is A. The two elements belong to group one of the periodic table; all elements in this group have only one electron in their outmost shell which they easily give away to other elements during chemical reactions in order to attain octet structure.

What Happens When extra Solute is added to unsaturated ,saturated and supersaturated solution

Eduardwww [97]

Answer:

If More solute is added and it does not dissolve,then the original solution was saturated. if the added solute dissolves,then the original solution was unsaturated. A solution that has been allowed to reach equilibrium but which has extra undissolved solute at the bottom of the container must be saturated.

The electrolysis of water has the equation 2H2O (l) → 2H2 (g) + O2 (g). What type of reaction is this?

Sonja [21]

Answer: The correct option is C) decomposition

Explanation:

Single displacement reaction is defined as the reaction where a more reactive element displaces a less reactive element from its salt solution.

$AX+B\rightarrow BX+A$

Element B is more reactive than element A

Double displacement reaction is defined as the reaction where an exchange of ions takes place in a solution

$AX+BY\rightarrow AY+BX$

Decomposition reaction is defined as the reaction where a single large chemical species breaks down into two or more smaller chemical species.

$AB\rightarrow A+B$

Synthesis reaction is defined as the reaction where two or more smaller chemical species combine together in their elemental state to form a single large chemical species.

$A+B\rightarrow AB$

For the given chemical reaction:

$2H_2O(l)\rightarrow 2H_2(g)+O_2(g)$

Here, water is breaking down into two smaller species of oxygen and hydrogen gas. Thus, it is a decomposition reaction.

Hence, the correct option is C) decomposition

A heterogeneous mixture is one in which substances are evenly distributed and have a uniform composition

Sati [7]

If you’re asking if this is true or false, it is false . A HOMOGENEOUS mixture is one the where the substances are evenly distributed and have a uniform composition, while a HETEROGENEOUS mixture is uneven and the substances are part from each like oil and water.
