What volume of water has the same mass as 9.0m3 of ethyl alcohol?
Triss [41]
This question requires the knowledge of density. 

The density of ethyl alcohol = 789 kg m⁻³
The density of water = 1000 kg m⁻³

Density = Mass / Volume 

By applying ethyl alcohol,
    789 kg m⁻³ = Mass / 0.9 m³
         Mass     = 710.1 kg
hence the mass of 0.9 m³ ethyl alcohol is 710.1 kg.

Then by applying water,
     1000 kg m⁻³ = 710.1 kg / Volume
      Volume        = 0.7101 m³
                          = 0.7 m³
hence the equal water volume is 0.7 m³

Decide whether a chemical reaction happens in either of the following situations. If a reaction does happen, write the chemical
sineoko [7]

Explanation:

A strip of solid palladium metal is put into a beaker of nicl2

Palladium (Pd) + Nickel Chloride (NiCl2)

To answer this question properly you must refer to the reactivity series.

The activity series is a chart of metals listed in order of declining relative reactivity. The top metals are more reactive than the metals on the bottom.

In this series, Nickel is higher than Palladium. This means that if a Palladium strip is placed into a solution of a Ni salt, then a reaction will not take place, nothing would happen.

Because Pd is lower than Ni in the reactivity series.

There is no reaction so no equation.
