Out of the following given choices;
<span>A. </span>Salt tablets
<span>B. </span>Bee pollen
<span>C. </span>Carnitine
<span>D. </span>Coenzyme Q10
<span>E. </span>None of the above
The answer is D. (none of the above). These elements are found naturally in nature and in our bodies. Coenzyme Q-10 and carnitine are found naturally in our bodies while bee pollen and salt are found naturally in our environments. Therefore, it is implausible to consider them ergogenic substances

Answer:
The sedimentary rock limestone which contains carbonate mineral Calcite and the metamorphic rocks which contain carbonate mineral Aragonite are the examples of rocks which react strongly with hydrochloric acid.
Explanation:
Rocks are naturally occurring structures formed on the Earth's crust and are composed of aggregate minerals. Classification of rocks: Igneous rocks - formed by cooling of magma on Earth's crust or seabed (basalts, gabbros, granite, etc), sedimentary rocks - formed over time by the accumulation of sediments from the weathering of existing rocks or fragments of minerals and organisms (mudstone, sandstone, shale, limestone, dolostone, siltstone, etc) and metamorphic rocks - transformed rocks formed from the existing rocks that are subjected to large pressures and temperatures (schists, gneiss, marble, etc).
The carbonate minerals like calcite, dolomite, aragonite, etc react with hydrochloric acid and release carbon dioxide gas bubbles. Calcite (calcium carbonate), which is found in igneous, metamorphic, and sedimentary rocks in a varying proportion reacts strongly with hydrochloric acid. So, the sedimentary rock Limestone which mainly contains calcite react strongly with the acid while Dolostone which mainly contains dolomite (calcium magnesium carbonate) reacts less vigorously. Another carbonate mineral aragonite, found in metamorphic rocks also reacts strongly with hydrochloric acid.

The composition of a star is abundant in hydrogen and helium, both of which are two of the lightest elements. Because they are very light, they are usually unstable. To becomes stable, hydrogen atoms spontaneously combine with each other through a radiation process called nuclear fusion, to yield helium atoms. This process requires very high energy in the form of heat. Therefore, these lighter elements are burned in order to keep the star alive with energy.
Therefore, the answer is D.
