Answer:

H+(aq) + OH-(aq) ⟶ H2O(l)

Explanation:

Step 1: The balanced equation can be presented as

HCN(aq) + KOH(aq) ⟶ H2O(l) + KCN(aq)

H+(aq) + CN-(aq) + K+(aq) + OH-(aq) ⟶ H2O(l) + K+(aq) + CN-(aq)

Step 2: The net ionic equation is formed by removing the spectator ions — those that appear on both sides of the equation — leading us to the final representation:

H+(aq) + OH-(aq) ⟶ H2O(l)

If 3.8 kcal is released by combustion of each gram of glucose, how many kilocalories are released by the combustion of 1.50 mol
castortr0y [3046]
684 kcal. One mole of glucose weighs roughly 180g. Given that 1g of glucose releases 3.8 kcal, we calculate for 1 mole of glucose: 180g -> 180g * 3.8 kcal/g = 684 kcal.

How many iodide ions are present in 65.5ml of .210 m AlI3 solution
castortr0y [3046]

Answer:

2.48\times 10^{22} ions are present in solution.

Explanation:

Molarity of the solution = 0.210 M

Volume of the solution = 65.5 ml = 0.0655 L

Moles of aluminum iodide = n

Molarity=\frac{\text{Moles of compound}}{\text{Volume of the solution(L)}}

0.210M=\frac{n}{0.0655 L}

n = 0.013755 moles of aluminum iodide

Each mole of aluminum iodide yields 3 moles of iodide ions:

Thus, 0.013755 moles of aluminum iodide will provide:

3\times 0.013755 moles=0.041265 mol moles of iodide ions

The total number of iodide ions in 0.041265 moles:

0.041265 mol\times 6.022\times 10^{23}=2.48\times 10^{22} ions

2.48\times 10^{22} ions are present in solution.

25 g of ethyl alcohol is dissolved in 100 ml of water (density = 0.99993 at 20 oc). what is the % w/w for the ethyl alcohol in t
lions [2927]
<span>The mass percentage represents the weight of a substance within a mixture in relation to a total mass of 100 units. It's also referred to as %w/w. To find this, you divide the mass of the solute by the total mass of the mixture. Given that we know the volume of water, we need to convert that volume into mass using its density. The calculation is as follows:

Mass of the solution = 100 mL (0.99993 g/mL) water + 25 g EtOH
Mass of the solution = 124.993 g of solution

%w/w = (25 g / 124.993 g) x 100
%w/w = 20% for EtOH</span>
