Answer:
C6 H10 O5+ 6O2-----> 6CO2+5H2O+heat
Explanation:
There are 6 carbon atoms in reactants to balance you put coefficient 6.
This makes the oxygen in CO2 12 so to balance put 6 in oxygen in reactants.
There are 10 hydrogen atoms in reactants to balance you put 5 in front of H2O in products.
If u recheck: 6 C atoms in reactants, 6 C atoms in products.
10 H atoms in reactants, 10 H atoms in products.
17 O atoms in reactants, 17 O atoms in products.
From what we know, we can confirm that the variations in colors are a mechanism intended to protect the plants from predators.
<h3>Why is color a protection mechanism?</h3>
This can be observed throughout nature. Many poisonous organisms have evolved bright colors intended to be noticed. Over time, this has resulted in many predators avoiding prey with bright colors, in order to avoid the possibility of being poisoned.
Therefore, we can confirm that the variations in colors are likely a mechanism intended to protect the plants from predators.

Answer:
C is the reaction intermediate.
Explanation:
A reaction intermediate is a molecular structure that is formed during the reaction but then is converted in the final products.
Usually, these reaction intermediates are unestable and, for that reason, the lifetime of these structures is low.
In the reaction, you can see in the first step C is produced, but also, in the second step reacts producing D. As is produced and, immediately consumed,
<h3>C is the reaction intermediate.</h3>
Answer:
pH = 5.19
Explanation:
Mixture of acetic acid with sodium acetate produce a buffer (Buffer is defined as the mixture of a weak acid with its conjugate base and vice versa). The pH of the buffer can be determined using Henderson-Hasselbalch equation:
pH = pKa + log₁₀ [A⁻] / [HA]
<em>Where pKa is -log Ka = 4.75; [A⁻] is the concentration of conjugate base (Acetate ion) and [HA] is molar concentration of the weak acid.</em>
-You can use moles of the compounds rather than its concentrations, that is:
[HA] = 0.147 moles
[A⁻] = 0.405 moles
Replacing in H-H equation:
pH = 4.75 + log₁₀ [0.405] / [0.147]
<h3>pH = 5.19</h3>
Answer:
Final pressure =P₂ = 15.13 psi
Explanation:
Given data:
Initial volume = 0.250 L
Initial pressure = 14.7 psi
Initial temperature = -80.0°C (-80.0 +273 = 193 K)
Final volume = 0.375 L
Final temperature = 25.0°C (25+273 =298 k)
Final pressure = ?
Solution:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
P₂ = P₁V₁ T₂/ T₁ V₂
P₂ = 14.7 psi × 0.250 L × 298 K / 193 K × 0.375 L
P₂ = 1095.15 psi .L. K / 72.375 K.L
P₂ = 15.13 psi
