The balanced molecular equation for the reaction between solid sodium bicarbonate and hydrochloric acid to produce carbon dioxide gas, water and aqueous solution of sodium chloride is
<h3>NaHCO₃(s) + HCl(aq) —> CO₂(g) + H₂O(l) + NaCl(aq) </h3>
The balanced equation can be written as follow:
Sodium bicarbonate => NaHCO₃
Hydrochloric acid => HCl
Carbon dioxide => CO₂
Water => H₂O
Sodium chloride => NaCl
Sodium bicarbonate + Hydrochloric acid —> Carbon dioxide + Water + Sodium chloride
<h3>NaHCO₃(s) + HCl(aq) —> CO₂(g) + H₂O(l) + NaCl(aq) </h3>
The equation above is balanced since the number of the different atoms of the elements present on both sides are equal.

Answer:
1038.96 kPa
Explanation:
We’ll use the ideal gas law; P1V1/T1 = P2V2/T2
P1*14.8/75.5 = 101.3*16.5/70.2
P1 = (101.3 * 16.5 * 75.5) / (70.2 *14.8)
P1 = 1038.96
Answer:
D
Explanation:
With there being more things (and technically more surface area) more organisms can hid in the little crevasses.
The S-Enantiomer of Valine is attached below.
Assigning S-Configuration:
In Valine there is only one <em>chiral carbon</em> (carbon to which all bonded atoms or group of atoms attached have different masses). This carbon also known as <em>alpha carbon</em> has a tetrahedral geometry. For S-configuration, according to<em> Cahn Ingold Prelog Rules</em> the -NH₂ group is assigned with priority order of 1, The carbon of carboxylic acid is assigned the number two and the tertiary carbon is assigned with number three. These three groups are made in such a way that moving from number 1 to number 3 makes a S sign or anticlockwise rotation while keeping the hydrogen atom behind the plane.
