A precipitate forms from a double displacement reaction or metathesis.

Explanation:

If given two clear solutions and upon reacting a cloudy/insoluble substance forms with the rest of the liquid being clear, a double displacement reaction has been carried out. The insoluble cloudy substance is called precipitate.

  1. the driving force for the bulk of double displacement reactions is the formation of precipitates.
  2. from careful observations, a solubility chart has been developed. If the compounds reacting are known, using the chart, a chemist can predict whether a precipitate will form or not.

What do we know about elements with half-filled energy levels??
lisabon 2012 [21]
If the energy level of a certain element is filled based on the maximum number of allowable electrons per level, then it is no longer reactive. With this, half-filled energy level means that the element may retain those electrons and attract electrons from other elements or it may give off its electrons.

Modern pennies are composed of zinc coated with copper. A student determines the mass of a penny to be 2.483 g and then makes se
Aleonysh [2.5K]

Answer:

97.1%

Explanation:

Using the ideal gas equation, the number of moles of hydrogen gas produced can be calculated from information provided about the volume of gas evolved at a given temperature and pressure.

The stoichiometry of the reaction is now used to obtain the number of moles of Zn that will produce a given number of moles of hydrogen from the balanced reaction equation as shown. This gives us the number of moles of zinc reacted hence the mass of zinc in the coin since it is assumed that all the zinc reacts.

This is now used to calculate the mass percentage of Zn as shown.

A 100-meter sprint is a race using only the straight side of a racetrack. A 400-meter sprint is a race that makes one complete l
Neporo4naja [7]
For 100m Race ,
displacement = distance covered .
divide the above equation by time t (assuming it takes t time to complete 100m race),
we get,
velocity = speed.
and for 400m race 1 lap is completed this means that racer's initial and final position coincide (or same) hence,
displacement = 0,
distance ≠0=400m.
=> displacement ≠distance.
=> velocity ≠ speed.
