Answer:

Li (s)  +   H₂O (l)  → 1/2 H₂ (g)  + LiOH (aq)

Explanation:

Lithium metal reacts with liquid water to form hydrogen gas and aqueous lithium hydroxide

2Li (s)  +  2H₂O (l)  → H₂ (g)  + 2LiOH (aq)

We can divide stoichiometry coefficients /2, to have the lowest stoichiometry.

What volume of so2 is produced at 325 k and 1.35 atm when 15.0 grams of hcl reacts with excess k2so3?
vova2212 [387]
The volume of SO2 produced at 325k   is calculated as  below

calculate  the moles of SO2 produced  which  is calculated as follows

write the  reacting equation
K2SO3 +2 HCl = 2KCl +H2O+ SO2

find the   moles  of  HCl  used
=mass/molar mass = 15g/ 36.5 g/mol =0.411 moles

by  use of mole ratio between  HCl to  SO2  which is  2:1 the moles of SO2 is therefore = 0.411 /2 =0.206  moles  of SO2

use the idea  gas  equation  to calculate the volume SO2
that is V=nRT/P  
where  n=0.206  moles
          R(gas constant) = 0.082 L.atm/ mol.k
         T=325 K
          P=1.35 atm

V=(0.206 moles x  0.082 L.atm/mol.k x325 k)/1.35 atm = 4.07 L of SO2

The amount of energy that must be absorbed or lost to raise or lower the temperature of 1 g of liquid water by 1°C _____. See Co
Klio2033 [76]

Answer:

Specific heat capacity

Explanation:

Heat capacity is defined as amount of the heat supplied or absorbed by the given mass of the material so to make a unit change in the material's temperature.

The SI unit is Joule / kelvin (J/K).

It is an extensive property.  

While,  

<u>Specific heat capacity is the amount of heat absorbed or lost by one gram of mass of the substance to raise it's temperature by 1°C or 1 K </u>

<u>It is an intensive property. </u>
