They are pure substances because they only contain one type of molecule (excluding impurities and contaminants).
Salt: Sodium Chloride* - NaCl
Sugar: Sucrose* - C12H22O11
Baking Soda: Sodium Bicarbonate - CHNaO3
*There are many, many different salts and several sugars; the ones above are the ones you would encounter normally (salt shakers and sugar cubes).
Sodium chloride in water is a mixture. Sodium chloride is a compound made of sodium and chloride ions, while water is a separate compound made of hydrogen and oxygen. When sodium chloride is dissolved in water, it forms a mixture where the two substances remain chemically unchanged.
Sodium chloride; the others are all elements.
Sodium chloride doesn't react with hydrogen.
becuse u suck d
Sodium chloride contain sodium and chlorine.
yes it yeilds oxygen and sodium chloride when the heatis applied to the sodium chlorate the heat decomposes the chemical into 2 substances sodium chloride in solid form and oxygen in gas form. NaClO3 + heat ----> NaCl + O3
Sodium chloride (NaCl) doesn't contain oxygen.
Yes, sodium can react vigorously with water to form sodium hydroxide and hydrogen gas. It can also react with oxygen in the air to form sodium oxide. Additionally, sodium can react with nonmetals, such as chlorine, to form ionic compounds like sodium chloride.
No, when sodium hydroxide and sodium chloride are mixed together, no chemical reaction occurs. They simply form a mixture of the two substances.
Sodium Chloride (salt), Carbon Dioxide, and Water
Sodium chloride is the product of reaction between sodium hydroxide and hydrogen chloride.
Three substances obtained from common salt are sodium chloride (table salt), bleach (sodium hypochlorite), and baking soda (sodium bicarbonate).
