Jerry prefers to burn bituminous coal in his fireplace because of the yellow flame. what causes that flame color?
a.
low carbon content
b.
high sulfur content
c.
high methane content
d.
softer structure
e.
lower heat value

The correct answer is B. High sulfur content.

Bituminous coal when burned produces yellow flames reason being combustion of hydrocarbons which are in the col are incomplete.

Another reason why bituminous burns in yellow colour is because of having different impurities for example, sulfur.

Incadence of soot particles which are very fine can also produce yellow flames.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
