Answer:
C
Explanation:
Spontaneous combustion is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self-heating which rapidly accelerates to high temperatures) and finally, ignition.
Answer:- 0.88
Solution:- Masses of silver and copper metals are given and we are asked to calculate the percentage of silver in the alloy.
mass percent of Ag = 
Mass of Ag = 17.6 g
mass of Cu = 2.40 g
mass of alloy = 17.6 g + 2.40 g = 20.0 g
Let's plug in the values in the formula:
mass percentage of Ag = 
mass percentage of Ag = 88%
So, the mass percentage of silver in sterling silver is 88% and in decimal form it is 0.88.
The object that shows fast motion is said to have a higher speed while the one with slow motion is said to have a slow speed.

Answer:
The question is incomplete. The spectra can be seen in the first picture in the attachment.
The molecule corresponds to the <em>tert</em>-amyl alcohol.
Explanation:
From the molecular formula, we can calculate the double bond equivalent, to know if there is any <u>unsaturation in the molecule</u>. For a compound of molecular formula CxHyOzXqNp

DBE= (2.2+2)-12 ÷12 = 0
Therefore, <u>the molecule does not have any unsaturation</u>.
Considering the chemical shift values and the multiplicity, the structure that satisfies the spectra corresponds to the <em>tert</em>-amyl alcohol (structure in attachment).
