Answer:

Lithium nitrate and water are product of given reaction.

Explanation:

Word equation:

Nitric acid + lithium hydroxide → Lithium nitrate + water

Chemical equation:

HNO₃ + LiOH → LiNO₃ + H₂O

The given reaction is balanced. There are two hydrogen, four oxygen, one lithium and one nitrogen atoms are present on both side of equation.

This reaction completely follow the law of conservation of mass.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

A cell has a standard emf of + 0.135 v at 298 k. part a what is the value of the equilibrium constant for the cell reaction if n

Irina-Kira [14]

To look for the value of the equilibrium constant for the cell where n=1, it is computed by:
Eo = RT / nF * ln(K)
(Eo * nF) /RT = ln(K)
(0.135 * 1mol* e- * 9.65E4C/mol*e) / (8.314J / molK * 298K) = ln(K)
10.52 = lnK
e^10.52 = e ^ lnK
K = e ^263/25
K = 37049.12 is the answer.

What is the density of a piece of metal that has a mass of 75.8g and a volume of 7.09

Mice21 [21]

Answer:

10.69g/cm^3 or 0.0106kg/m^3

Explanation:

10.69 g/cm^3: I wrote this answer because your question doesn't mention whether volume is in cm^3 or m^3. If its in cm^3, then this is your answer.

0.0106kg/m^3: This might also be the answer if the volume is in m^3. If it is in m^3 then you have convert grams into kilograms.

So technically since you questions incomplete, the equation for measuring density is P= m/v

P= rho (density)

m= mass

v= volume
