When a fuel burns, it combines with oxygen int the air and changes into the substances water and carbon dioxide. That's how Flammability is a chemical property.
Answer:
Explanation:
The difference between bond pair & lone pair is that a bond pair is composed of two electrons that are in a bond . a lone pair is composed of two electrons that are not in a bond.
Answer:
energy is released in the reaction.
Explanation:
Part A: Given mass of NaCl * 1mol of NaCl/molar mass of NaCl = # of moles
17.45 g NaCl * 1 mole of NaCl /58.44 g NaCl = 0<em>.298 moles of NaCl</em>
Part B: First, let’s start with sodium, Na. To find the given mass of sodium, divide the given mass of NaCl (17.45)/the molar mass of NaCl(58.44) and multiply that by the molar mass of Na(22.99) to get the given mass of Na.
Given mass of Na * 1mol of Na/molar mass of Na= # of moles of Na.
6.864* 1mol Na/22.99 g Na=0.298 moles of sodium.
Repeat the above steps with chlorine.
Given mass of Na or Cl*1mol of Cl/molar mass of Cl = # of moles Cl.
10.58* 1mol Cl/ 35.45 g of Cl= <em>0.298 moles of chlorine.</em>
