Answer:
669 Liters
Explanation:
From the equation, it takes 3/2 as much hydrogen as ammonia gas
3/2 * 446 = 669 Liters of H2 gas

<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 )
The mineral is calcite.
Lustre — glassy; ∴ non-metallic
Hardness — between a fingernail (2.5) and a penny (3)
Streak — white
Specific gravity — 54/20 = 2.7
Colour —white
Acid reaction — Fizzes; ∴ a carbonate
The only carbonate mineral that satisfies all these criteria is calcite, CaCO₃.
<span>chemicals reacting are written on the left, what is formed is written on the right after the = sign
eg Copper + oxygen = copper oxide.
Hope this helps , mark as brainliest and say thanks THANKS..</span>
