Hello!
In this case, since we are asked to note down the complete molecular equation, complete ionic equation and the net ionic equation for the reaction between acetic acid (weak acid) and barium hydroxide (strong base), we proceed as shown below:
- Complete molecular equation:
- Complete ionic equation: in this case, since acetic acid is a weak one, it is not ionized, so we do this:
- Net ionic equation: in this case, we cancel out the barium ions as they are the spectators one because they are present at both reactants and products:
Best regards!
Answer:
The answer to your question is density = 635.3 g/ml (check the units)
Explanation:
Data
density = ?
volume = 85 ml
mass = 54 kg
Density is a physical property that relates the mass of an object and its volume.
The unit of this property are g/ml or kg/m³
In this problem, I will calculate the density in g/ml
Formula
density = mass/ volume
-Substitution
density = 54000 / 85
-Simplification
density = 635.3 g/ml
Answer:
Option D
Explanation:
A solution is neutral if it contains equal concentrations of hydronium and hydroxide ions; acidic if it contains a greater concentration of hydronium ions than hydroxide ions; and basic if it contains a lesser concentration of hydronium ions than hydroxide ions.
A common means of expressing quantities, the values of which may span many orders of magnitude, is to use a logarithmic scale.
The hydroxide ion molarity may be expressed as a p-function, or pOH.
pOH = −log[OH−]
Basic solutions are those with hydronium ion molarities less than 1.0 × 10−7 M and hydroxide ion molarities greater than 1.0 × 10−7 M (corresponding to pH values greater than 7.00 and pOH values less than 7.00).
Definitely, the correct answer is option B. When Ca(OH)2 is added into a beaker, the solution will turn into pink when the indicator phenolphthalein is added. This is due to the hydroxide ions from the calcium hydroxide dissolved in water. The compound dissociates into calcium ions and hydroxide ions.
Answer:
1) Yes
2) No
Explanation:
A strip of solid magnesium metal is put into a beaker of 0.053M ZnSO4 solution-YES
A chemical reaction occurs
Mg(s) + ZnSO4(aq) ----------> MgSO4(aq) +Zn(s)
This reaction is possible because magnesium is far higher than zinc in the activity series of metals hence magnesium can displace zinc from a solution of a zinc salt.
A strip of solid zinc metal is put into a beaker of 0.058M MgBr2 solution. NO
A chemical reaction does not occur because magnesium is higher than zinc in the activity series hence zinc cannot displace magnesium from a solution of its salt.
