Answer:
C. C₆H₁₂O₂
Explanation:
Step 1: Count the number of H atoms
12 H atoms present
Step 2: Count the number of C atoms
6 C atoms present
Step 3: Count the number of O atoms
2 O atoms present
Step 4: Combine
C₆H₁₂O₂
The equation ΔHsoln = ΔH1+ΔH2+ΔH<span>3 means that either the solution is endothermic (</span>ΔH < 0, the resulting reaction is cold) or exothermic (ΔH>0, the resulting reaction is hot). The lattice energy can be solve through this equation,
<span>lattice energy = </span>ΔHsolvation - IMF - ΔHsoln<span>
</span>
Hi!
The generic equation showing how a weak base ionizes water is the following:
B(aq) + H₂O(l) ⇄ BH⁺(aq) + OH⁻(aq)
A base is described as weak when its dissociation is difficult and isn't complete. Weak Bases are chemical compounds that accept protons from water, to form the conjugate acid and the OH⁻ ion. The pH of the solution of a weak base is higher than 7. Some weak bases include ammonia (NH₃), Aluminum Hydroxide (Al(OH)₃) and Sodium Acetate (CH₃COONa).
Have a nice day!
Answer:
8.3mL
Explanation:
According to the question, the initial volume of a measured amount of water is 12.5mL. Karen then adds a rubber stopper that weighs 2.3grams. This increases the volume of the water.
The increase in the volume of the water is attributed to the rubber stopper. Hence, to calculate the volume of the rubber stopper, we subtract the initial volume of the water from the final volume. i.e.
Volume of added rubber stopper = final volume of water - initial volume of water
= 20.8 - 12.5
= 8.3mL
Hence, the volume of the rubber stopper is 8.3mL
