The answer to your question would be: true
<h2>T
he mass of a liquid substance affected after it boils : C it stays the same</h2>
Explanation:
Matter
Anything that occupies space and has mass .
The states of matter are :
Solids
Liquids
gases
Interconversion of state of matter
Solid ------liquid -----------Gas
(on heating ) (on heating )
- One state can be changed in to another by changing the condition of temperature , pressure etc .
- When liquid is boiled , it gets converted to gaseous form on heating .The heat supplied to change the state of matter is called latent heat .
- This latent heat , just helps in increasing the spaces between particles and decreasing the forces between them Hence we can say that it helps in changing the state .But it doesn't change the mass .Hence mass of substance remains the same .
- Similarly , gas -----> liquid -----> solid
(on cooling ) (on cooling )
Answer:
iron (III) bromide
Explanation:
Bronsted-Lowry acid -
The species which can release proton , when dissolved in water .
Lewis acid -
The electron deficient species are called the Lewis acid .
From the question ,
The iron (III) bromide is a Lewis acid but not a Bronsted- Lowry acid because it can accept electrons pairs but cannot release proton .
The other options are -
The hydronium ion, the hydrochloric acid and the acetylene are Bronsted- Lowry acids because they can release proton .
And since , all the Bronsted- Lowry acids are Lewis acids .
