How much pure water must mixed with 8 pints of 50 developer to produce a mixture that is 24%?
Galina-37 [17]
8:24 = 0.333(3) pints is one percent
0.333(3)* 100=33.333(3) pints will be 24% mixture with the water
33.3333-8=25.333 pints of water is required for producing 24% mixture

25.3333 pints of pure water and 8 pints of juce.

The table shows the thermodynamic data for a reaction. Thermodynamic Data Energy of the Reactants Energy of the Products Activat
NNADVOKAT [17]

Answer:

The change in enthalpy is +210 kJ, so it is an endothermic reaction.

Explanation:

  • The change in enthalpy shows that the reaction is exothermic or endothermic.

The change in enthalpy = The energy of products - the energy of reactants.

  • If ΔH is positive value, the reaction is endothermic, the energy of the products is higher than that of the reactants.
  • If ΔH is negative value, the reaction is exothermic, the energy of the products is lower than that of the reactants.

<em>For this reaction: </em>The change in enthalpy = The energy of products - the energy of reactants = 370 kJ - 160 kJ = + 210 kJ.

<em>So, the right choice is: The change in enthalpy is +210 kJ, so it is an endothermic reaction.</em>

Which of the following elements has the strongest ionization energy: Mg or Cl? Define ionization
Mila [183]

Answer:

Cl

Explanation:

The element Cl will have the strongest ionization energy from the given choices. Most non-metals have higher ionization energy compared to metals.

Ionization energy is the energy required to remove the most loosely held electron from the gaseous phase of an atom.

  • As you go from left to right on the periodic table, it increases progressive
  • From top to bottom, the ionization energy reduces significantly.
  • The attractive force between the protons in the nucleus and the electrons plays a very important role.
  • In metals, they have very large atomic radius, the attractive force on the outer electrons is very weak.
  • This is not the case in non-metals
