The two can be mixed in water, since the salt is soluble it will dissolve and the sand will remain. To separate it from the water use filter paper and a beaker.
Answer:
1.67 atm.
Explanation:
- We can use the general law of ideal gas: PV = nRT.
where, P is the pressure of the gas in atm (P = ??? atm).
V is the volume of the gas in L (V = 5.0 L).
n is the no. of moles of the gas in mol (n = 0.5 mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = 203 K).
∴ P = nRT/V = (0.5 mol)(0.0821 L.atm/mol.K)(203 K)/(5.0 L) = 1.67 atm.
Answer:
Forgive me if im wrong but i am pretty sure the answer is C
Explanation:
Answer:966.45ml
Explanation:
Using Charles law.. V1/T1=V2/T2
V1=535ml
T1=-25+273
=248k
T2= 175+273=448k
V2=?
V2= V1*T2/T1
V2=535*448/248
V2=239680/248
V2=966.45ml
Answer:
"Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings of the reaction."
