2Li +__H₂0= __LiOH+H₂ balance the equation

Chemistry

2Li+2H2O=2LiOH+H2

We need to make number of the atoms of each reactant(the elements from the left side)equaled to the products(the elements from the right side)

Li is 2 on the left side so in order to make it balanced we add a 2 in front of LiOH.

For the H2O we take a look at the right side there are 2 atoms from H2 and 2 atoms of H for 2LiOH therefore we have 4 atoms of H in the right side and only 2 in the left side.So,to make them equal we will add a 2 in front of H2O.

Hope,I explained well.

The sodium salt, NaA, of a weak acid is dissolved in water; no other substance is added. Which of these statements (to a close a
ddd [48]

Answer:

Your question is somewhat poorly worded, even so what I can contribute is the statement is false, since the salt is sodium chloride, where its severe chemical formula NaCl, is a SALT not an acid and if it dissolves in water, seriously the solute of a solution, where water plays the role of the solvent

Explanation:

Sodium chloride is a binary salt, very easy to dissolve in water, it is also called the famous table salt, since it can be ingested in food even though it is not so recommended against high blood pressure conditions.

Help please !!!!!!!!
Elena L [17]

Answer:

Option B. 2096.1 K

Explanation:

Data obtained from the question include the following:

Enthalpy (H) = +1287 kJmol¯¹ = +1287000 Jmol¯¹

Entropy (S) = +614 JK¯¹mol¯¹

Temperature (T) =.?

Entropy is related to enthalphy and temperature by the following equation:

Change in entropy (ΔS) = change in enthalphy (ΔH) / Temperature (T)

ΔS = ΔH / T

With the above formula, we can obtain the temperature at which the reaction will be feasible as follow:

ΔS = ΔH / T

614 = 1287000/ T

Cross multiply

614 x T = 1287000

Divide both side by 614

T = 1287000/614

T = 2096.1 K

Therefore, the temperature at which the reaction will be feasible is 2096.1 K
