The half-life of polonium-218 is 3.0 minutes. If you start 10.0 g, how long will it be before only 5.0 g remains?

The half life of an isotope means how long it will take for the amount of given isotope to decay to only 1/2 of the original amount.

If you start with 10.0g of polonium-218 and the half life is 3.0 minutes, then in 3.0 minutes you will have half of the original amount

Half of the original amount is equal to 5.0g

<em>The answer is </em><em>5.0g</em>

Determine the limiting reactant in each of the following reactions:
wolverine [178]

The reactant in a chemical process known as the limiting reactant controls how much product can be produced. When the limiting reactant is completely used up, the reaction will come to an end.

<h3>Find the limiting reactant ?</h3>
  • As a result of 1 mol Sb4O6 reacting with 6 mol H2SO4, only 0.1 mol Sb4O6 reacts with 0.6 mol H2SO4, leaving only 0.5 mol H2SO4. This indicates that H2SO4 is the limiting reactant and Sb4O6 is present in excess.
  • According to your equation, which is balanced, 0.1 mol Sb4O6 should react with 0.6 mol H2SO4, yet there is only 0.5 mol H2SO4 on hand.
  • Therefore, only.083 mol of Sb4O6 are reacted.
  • The reactant that is present in the limiting amount—the limiting reactant—determines the extent to which a chemical reaction occurs.
  • The trick is really quite easy! We employ an augmented matrix to hold the data derived from the balancing equation Sb4O6 + 6H2SO4 --> 2Sb2(SO4)3 + 6H2O.
  • Although you are provided 0.5 mol of H2SO4, the reaction requires 0.6 mol. Therefore, the limiting reactant is H2SO4.
  • Only 0.0833 mol of Sb4O6 is required, but you have 0.1 mol. Sb4O6 is therefore the extra reactant.

0.75 moles of an unknown acid are dissolved in water. If 0.42 moles of H3O+ form, what was the percent dissociation of the unkno
AnnZ [28]

Answer:

56 %

Explanation:

The percent dissociation of a weak acid can be defined as:

Moles of weak acid that produced H₃O⁺ species / Total number of weak acid moles * 100%

We are given all the required data to <u>calculate the percent dissociation</u>:

0.42 mol / 0.75 mol * 100 % = 56 %

The percent dissociation is 56%.

Define each of the following wave phenomena, and give an example of where each occurs: (a) refraction;
Svetach [21]

Refraction is the phenomenon of change in the speed of light when the light when passes from the medium of one optical density to a medium of another optical density. The light rays also show a bending when passing through the interface of such a medium.

<h3>What causes wave refraction?</h3>

Refraction is the bending of waves due to a change in speed as they travel through different media. Waves may accelerate or decelerate when they go obliquely from one medium to another. The waves will bend more dramatically as their speed changes.

<h3>What characteristics does a wave have?</h3>

The following characteristics of waves:

  • Refraction is the bending of waves as they move from one medium to another due to a change in their speed.
  • Waves may speed up or slow down as they transition from one medium to another at an angle.
