Answer:
Find the steps and explanation below.
Explanation:
A. Kids make slime following these basic steps;
1. In a bowl, is 1/4 cup of water is added to 1 oz. of glue. Add coloring if you wish to.
2. 1/4 cup of Borax solution, also known as Sodium Tetraborate is added to the mixture and gradually stirred.
3. The mixture is kneaded with the hands to ensure a smooth consistency.
4. Water remnants are discarded and the slime is stored in a plastic bag and kept in the fridge.
B.
What each ingredient does
Polyvinyl acetate present in the glue acts as a liquid polymer.
Borax binds the liquid polymers together.
Water eases the mixing process
C.
If lesser ingredients are used, the slime will not have its characteristic slimy nature. If excess of the ingredients are used, the slime becomes very sticky.
a usually irreversible chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance: The formation of rust on iron is a chemical change. Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
Answer:
1.3 x 10²⁴ atoms Fe
Explanation:
To convert moles to atoms, you need to multiply your given value by Avogadro's Number. This causes the conversion to occur because Avogadro's Number exists as a ratio. It is the ratio that allows for the cancellation of units during multiplication. This is why atoms should be in the numerator of your conversion. The final answer should have 2 sig figs to reflect the given value.
Avogadro's Number:
1 mole = 6.022 x 10²³ atoms
2.1 moles Fe 6.022 x 10²³ atoms
--------------------- x ------------------------------- = 1.3 x 10²⁴ atoms Fe
1 mole
Answer:
white light is separated into its component colors red, orange, yellow, green, blue and violet.
Explanation:
Visible light, also known as white light, consists of a collection of component colors. These colors are often observed as light passes through a triangular prism.
carbon dioxide reacts with water to create carbon acid which is a rather weak acid but still acid is acid
hope this helps :)
