Answer:
Reflection
Explanation:
Because light is bouncing of the object
<h3>
Answer:</h3>
2NaOH(aq) + CaCl₂(aq) → 2NaCl(aq) + Ca(OH)₂(s)
<h3>
Explanation:</h3>
- The equation for the reaction between calcium chloride and sodium hydroxide to form calcium hydroxide and aqueous sodium chloride is given by;
2NaOH(aq) + CaCl₂(aq) → 2NaCl(aq) + Ca(OH)₂(s)
- It is an example of precipitation reaction in which a precipitate is formed as one of the products.
- During precipitation two aqueous solution combine to form a insoluble salt and a soluble salt.
If an electron absorbs enough energy it would jump to a higher energy level.
Answer:
1) ) CBr₄ has a higher boiling point than CCl₄: True
2 CBr₄ has weaker intermolecular forces than CCl₄: False
3) CBr₄ has a higher vapor pressure at the same temperature than CCl₄: False
4) CBr₄ is more volatile than CCl₄: False
Explanation:
1) ) CBr₄ has a higher boiling point than CCl₄: True :
Due to higher molecular weight CBr₄ has more london disperion forces thus making the intermolecular interactions stronger and thus it need more temperature to boil it off.
2 CBr₄ has weaker intermolecular forces than CCl₄: False
Due to higher molecular weight CBr₄ has more london disperion forces thus making the intermolecular interactions stronger.
3) CBr₄ has a higher vapor pressure at the same temperature than CCl₄: False
Due to higher molecular weight CBr₄ has more london disperion forces thus making the intermolecular interactions stronger. Thus the vapor pressure of it will be less than CCl₄ at the same temperature.
4) CBr₄ is more volatile than CCl₄: False
Due to higher molecular weight CBr₄ has more london disperion forces thus making the intermolecular interactions stronger. Thus CCl₄ is more volatile.
