Explanation:
4. limestone heat lime + carbon dioxide
The reactants in this expression above is limestone
The products of the reaction is carbon dioxide and lime
Reactant is the species that gives the product and it is usually found on the left hand side of the expression.
The product is the substance on the right hand side of the expression that forms through the experiment.
Heat is used to facilitate the reaction.
5. An exothermic reaction is a reaction in which heat is given off.
An endothermic reaction is a reaction in which heat is absorbed in the process.
An exothermic reaction is always warmer after the reaction whereas an endothermic reaction is colder at the end of the reaction.
6. Sodium salicylate is made from carbon dioxide and sodium phenoxide.
The reactants are:
Carbon dioxide and sodium phenoxide
The product is:
Sodium salicylate
Answer:
The skin
Explanation:
The skin is the largest organ of the body. The skin and its derivatives (hair, nails, sweat and oil glands) make up the integumentary system. One of the main functions of the skin is protection. It protects the body from external factors such as bacteria, chemicals, and temperature.
The less valence electrons there are, the less stable the atom becomes, causing it to react with other atoms. More valence electrons adds mass to the atom, making it less reactive
Answer:
a surface of contact between two groups of unconformable strata.
"erosion beneath the Hercynian unconformity has removed most of the Westphalian strata"
the condition of being unconformable.
Explanation:
Seen from Desert Tower, the Great Unconformity is the boundary between the flat-lying Tapeats sandstone (and overlying Paleozoic rocks) and tilted rocks of the Grand Canyon Supergroup (GCS).
thats all I know so i hope this helps
Two solid samples, each contain sulfur, oxygen, and sodium only. These
samples have the same color, melting point, density, and reaction with
aqueous
barium chloride (means water added to barium chloride, BaCI2) It can be concluded that the two samples are the same.
It is a A. compound.
