Answer:
c. 
Explanation:
Hello,
Due to the fact that an odorless gas was released, the chemical reaction between lithium carbonate and a random acid (for instance hydrochloric acid) turns out into:

It is known that carbonic acid is unstable and it quickly decomposes into water and carbon dioxide which is an odorless gas. In spite of the fact that the
releases
it isn't the solid since that gas is odorous.
Best regards.
Methane CH
does not have ionic bonds. Because of the close value of electronegativity of the carbon and hydrogen atoms the electrons are shared forming covalent bonds.
Answer:
Exothermic
q = -8.03 kJ/g
Explanation:
<em>When 2 moles of Na(s) react with H₂O(l) to form NaOH(aq) and H₂(g) according to the following equation, 369 kJ of energy are evolved.</em>
The thermochemical equation is:
2 Na(s) + 2 H₂O(l) → 2 NaOH(aq) + H₂(g) ΔH = -369 kJ
Since the energy is evolved, the reaction is exothermic, which is why the enthalpy of the reaction (ΔH) is negative.
The heat released (q) per gram of Na(s) is (molar mass 22.98 g/mol):

Answer:
The answer to your question is 0.13 M
Explanation:
Data
[HNO₃] = ?
moles of HNO₃ = 9.8 x 10⁻²
volume = 705 ml
Process
1.- Convert volume to milliliters
1000 ml ------------------ 1 L
705 ml ------------------ x
x = (705 x 1) / 1000
x = 705 / 1000
x = 0.75 L
2.- Calculate the molarity
Molarity = moles / volume
Molarity = 9.8 x 10⁻² / 0.75
Molarity = 0.13
