Water vapour particles are most likely to phase change into liquid particles if the vapour particle come into contact with A COOLER SURFACE.
For a liquid to change to gas, it has to absorb enough energy to break the chemical bond that is holding the liquid particles together. When a liquid change to gas it is called vaporization. When a vapour, for instance water vapour comes in contact with cooler surfaces they lose energy and get converted back to the liquid state; this process is called condensation.
Answer:
it is a chemical change
Explanation:
it is a chemical change since the lemon juice can not be returned to its original form some part of it had been converted to gas form
Unbalanced it should be 2Zn+2Hcl=2ZnCl2+H2
<span>Thermochromic ink is a kind of material that takes advantage of thermochromism. In chemistry, this is where a substance changes hues when exposed varying kinds of temperature. In the fashion industry, these inks are used for creating different kinds of accessories, clothing and bag designs. </span>
Answer is: 4,4 grams <span>of carbon dioxide gas would be produced.
</span>Chemical reaction: CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O.
m(CaCO₃) = 10 g.
n(CaCO₃) = 10 g ÷ 100 g/mol.
n(CaCO₃) = 0,1 mol.
From chemical reaction: n(CaCO₃) : n(CO₂) = 1 : 1.
n(CO₂) = 0,1 mol.
m(CO₂) = n(CO₂) · M(CO₂).
m(CO₂) = 0,1 mol· 44 g/mol.
m(CO₂) = 4,4 g.
