Proton is a positively charged particle
Answer:
Increases
Explanation:
As ice melts into liquid water, the kinetic energy of the particles increases.
This is because to melt ices, heat energy is supplied.
- The sum total of all the average speed of the particles in a substance is the heat energy.
- Heat is a form of kinetic energy.
- As more heat is added, the particles moves rapidly and the kinetic energy increase.
Answer
Ionic compounds are formed when metals react with non-metals . Ionic compounds held together by ionic bonds are classed as ionic compounds.
Explanation:
I used this to awnser this queston when I was a freshmen in high school.
Answer:
The volume of nitrogen oxide formed is 35.6L
Explanation:
The reaction of nitric acid with copper is:
Cu(s) + 4HNO₃ → Cu(NO₃)₂ + 2NO₂(g) + 2H₂O(l)
Moles of copper are:

Moles of nitric acid are:

As 1 mol of Cu reacts with 4 moles of HNO₃:
0.697 mol Cu × (4mol HNO₃ / 1mol Cu) = 2.79 moles of HNO₃ will react. That means Cu is limiting reactant.
Moles of NO₂ produced are:
0.697 mol Cu × (2mol NO₂ / 1mol Cu) = <em>1.394 moles of NO₂</em>
Using PV = nRT
<em>Where P is pressure (735torr / 760 = 0.967atm); n are moles (1.394mol); R is gas constant (0.082atmL/molK); T is temperature (28.2°C + 273.15 = 301.35K). </em>
Thus, volume is:
V = nRT / P
V = 1.394mol×0.082atmL/molK×301.35K / 0.967atm
V = 35.6L
<em>The volume of nitrogen oxide formed is 35.6L</em>
