A pH of 2 indicates a acid
Answer:
Rubber, or another insulator.
Explanation:
I'm not sure what the options are, but Sue would probably want an insulator so that the heat is trapped, keeping her hands cool.
D = mass / volume
d = 100 g / 100 mL
d = 1.0 g/mL
The answer is: when the aim is to show electron distributions in shells
An orbital notation is more appropriate if you want to show how the electrons of an atom are distributed in each subshell. This is because there are some atoms that have special electronic configurations that aren't obvious in just written configurations.
Answer:
the products formed are : -
1. CaCO3 - Calcium Carbonate
2. NaCl - Sodium Chloride
Explanation:
Calcium chloride reacts with Sodium carbonate to form Calcium carbonate and Sodium chloride. this reaction is a double displacement reaction.
here's the balanced chemical equation for the above reaction : -
CaCl2 + Na2CO3 =》CaCO3 + 2 NaCl
