Sodium’s combination with water creates a colourless result of sodium hydroxide (NaOH) and hydrogen gas (H2). ... The reaction is exothermic. During the reaction, the sodium metal become very hot, to the point where it can catch fire and burns with a characteristic orange colour.
Answer:
The steps that must be long to obtain separately the components (to the substances) of a mixture of water, salt and sand, are respectively: A) filtration and siphoning B) decanting and siphoning C) simple filtration and distillation D) collection and decantation.
Simple filtration and Siphoning is the method. When an insoluble solid is present in a liquid. Filtration is the ideal method of separation,The sand is filtered by the filtered paper as water is allowed to pass through the filter paper into a beaker where the funnel which hold the filter paper emptied into.
Water molecules is Siphoned, pull by force of gravity through the sand, past the filter paper to emerge as clean in the beaker below.
Answer: c12 has a mass of 12 amu
Explanation:
mass of one mole of c12 = g. So mass of 1 atom of c12 = 1.9927e-23g
I dont know if this is right but i think the answer is 10.8 kilometers
An atom has a nucleus filled with neutrons and protons, and electrons circle the outside of it.
