Answer:
The answer to your question is 1.46 g of Cl₂
Explanation:
Data
mass of Cl₂ = ?
mass of NaCl = 2.4 g
Chemical reaction
2Na + Cl₂ ⇒ 2NaCl
Process
1.- Calculate the molar mass of chlorine and sodium chloride
Molar mass Cl₂ = 2 x 35.5 = 71 g
Molar mass of NaCl = 23 + 35.5 = 58.5 g
2.- Use proportions to solve this problem
71g of Cl₂ --------------------- 2(58.5g) NaCl
x --------------------- 2.4 g
x = (2.4 x 71) / 2(58.5)
x = 170.4 / 117
x = 1.46 g of Cl
Answer:
Explanation:
When LiOH and carbon dioxide reacts , they form lithium carbonate and water.
The skeletal equation will be:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced equation will be:
Answer:
The opposite charges of the atoms hold the atoms together. One atom can have a positive charge while the other can have a negative charge and this causes an electrostatic attraction causing the atoms to stick to each other like glue. For example, two magnets, can only be attracted to each other when one side of the magnet has a "-" while the other magnet on one side has a "+". They are attracted to each other by these varying charges. The same applies to ionic compounds which are held together by the varying charges of the ions.
