</span>There are two hydrogen atoms, one sulfur atom, four oxygen atoms, one barium atom and two chlorine atoms in this chemical reaction.
Answer: Usually, the rock pieces, called sediments, drop from the wind or water to make a layer. The layer can be buried under other layers of sediments. After a long time the sediments can be cemented together to make sedimentary rock. In this way, igneous rock can become sedimentary rock.
Explanation:
Answer:
23.60 mL NaOH
Explanation:
The reaction is CH3COOH + OH- --> CH3COO+ + H2O
Since the reaction is one-to-one, we can use M1V1 = M2V2.
M1 = 0.1894 M CH3COOH
V1 = 25.00 mL CH3COOH
M2 = 0.2006 M NaOH
V2 = ?
Solve for V2 --> V2 = M1V1/M2
V2 = (0.1894 M)(25.00 mL) / (0.2006 M) = 23.60 mL NaOH
The problem applies Charles' law since constant pressure with varying volume and temperature are given. Assuming ideal gas law, the equation to be used is
=
. We make sure the temperatures are expressed in Kelvin, hence the given added with 273. The volume 2 is equal to 25.2881 liters.
Heat of vaporization (During which the temperature stays the same)
