Answer:
Carbon iv oxide + water - - carbonic acid
Explanation:
CO2 + H2O--H2CO3 (balanced equation)
Answer:
Q,N,1) lithium + hydrochloric -> lithium chloride + Hydrogen.
- word equation ( 2li + 2HCl -> 2liCl + H2)
I think the answer might be C. Planets. Not exactly sure though... Let me know if this was correct!! :-)
Answer:
90.5mL is the volume of the gas at STP
Explanation:
It is possible to find volume of a gas when conditions of temperature and pressure change using combined gas law:

Where P is pressure, V is volume and T is absolute temperature. 1 is initial conditions and 2 final conditions.
If initial conditions are 1.08atm, 80.0mL and absolute temperature is (-12.5°C + 273.15) = 260.65K.
And STP are 1atm of pressure and 273.15K of absolute temperature. Replacing:

V₂ = <em>90.5mL is the volume of the gas at STP</em>
A catalyst increases the reactions rate
