Thermal decomposition of rail car load of limestone to lime and carbon dioxide requires 7.92 x 106 kj of heat. convert this energy to calories. once you have the value, determine its log (base 10) and enter this in decimal format with three decimal places. do not include units.

Explanation:

As we know that one kilo joules is equal to gram calories

Given ,

Energy required by thermal decomposition of rail car load of limestone to lime and carbon dioxide is equal to

Kilo joules

This kilo joules of energy is converted into calories and is equal to

On taking the log of this value, we get -

log ()

Hence, the answer is

a chair, a bed, and a toothbrush

explanation:

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.
