Suppose you had four spoons the same size and shape made out of glass, plastic, steel, and wood. Which spoon handle would get ho
Burka [1]

Answer:

A. steel spoon

Explanation:

A steel spoon will get hot the quickest from the different given spoon. This is because steel is predominantly made up of a metal which shows metallic properties such as heat conduction.

  • Metals have low specific heat capacity which is the amount of head needed to raise 1g of a substance by 1°C.
  • By so doing, metals will conduct heat at a very fast rate.
  • The delocalized electron around the central nucleus plays very important role.

Other properties originating from metallic bonds are ductility, malleability, luster etc.

The concentration of hydroxide ions is greater than the concentration of hydronium ions for acidic solution. True or false.
larisa86 [58]

Answer: False

Explanation:

An acid is defined as the substance which looses hydrogen ion or hydronium ions when dissolved in water.

A base is defined as the substance which looses hydroxide ions when dissolved in water.

If the solution has higher hydronium ion concentration as compared to the hydroxide ion concentration, then the pH will be low and the solution will be acidic.

If the solution has low hydronium ion concentration as compared to the hydroxide ion concentration then the pH will be high and the solution will be basic.

If 1.00 g of a hydrocarbon is combusted and found to produce 3.14 g of co2, what is the empirical formula of the hydrocarbon?
photoshop1234 [79]
The combustion reaction is as expressed,

                CxHy + O2 --> CO2 + H2O

The mass fraction of carbon in CO2 is 3/11. Hence,
       mass of C in CO2 = (3.14 g)(3/11) = 0.86 g C.

Given that we have 1 g of the hydrocarbon, the mass of H is equal to 0.14 g. 

     moles of C = 0.86 g C / 12 g = 0.0713
     moles of H = 0.14 g H / 1 g  = 0.14

The empirical formula for the hydrocarbon is therefore, CH₂.
