The type of reaction that occurs without the addition of heat is called spontaneous reaction. That is option D.
<h3>What is spontaneous reaction?</h3>
Spontaneous reaction is defined as the reaction where by new substances are formed naturally without the addition of extra energy in the form of heat.
Therefore, the type of reaction that occurs without the addition of heat is called spontaneous reaction

Answer:
Litmus paper is one type of acid-base indicator. The paper is imbued with dye derived from lichens that change color in response to the presence of an acid or base. ... Red paper is used to detect alkaline pH and will turn a shade of blue in the presence of a basic solution.

A. The box will move to the right
10 mL of 0.1 M NaOH is equal to 1 equivalent of base, if titrating 10.00 mL of 0.1 M amino acid.
Given :
0.1 M NaOH
0.1 M Amino acid
10.00 mL volume of Amino acid
<em> R-CH(NH₂)-COOH + NaOH → R-CHNH₂Na + H₂O</em>
In this case, end factor = 1 and It is 1 mole / 1 mole ratio
Since, the concentration of amino acid and NaOH are same, that is 0.1 M.
Concentration of amino acid = concentration of NaOH
0.1 M = 0.1 M
Therefore, 10 mL of NaOH is required to neutralize 10 mL of amino acid and the end factor is equivalent to 1.
Hence, The volume of 0.1 M NaOH is equal to 1 equivalent of base.
