If you need help reading it then ask away, the two answers end up being, 2Na, and 2NO3

Answer:
5.41 x 10²² g
Explanation:
Data Given:
no. of moles of sodium = 2.35 x 10²¹ moles
mass of sodium = ?
Solution:
Formula used
no. of moles = mass in grams / molar mass
To find mass rearrange the above equation:
mass in grams = no. of moles x molar mass. . . . . . (1)
- molar mass of Sodium (Na) = 23 g/mol
Put values in equation 1
mass in grams = 2.35 x 10²¹ moles x 23 g/mol
mass in grams = 5.41 x 10²² g
So,
mass of Sodium (Na) = 5.41 x 10²² g
No reaction will occur when NiCl₂(aq.) is added to a test tube containing Zn(NO₃)₂(aq). As to a reaction to occur between two solutions that most probably undergoes a double displacement reaction , it has to meet the following requirements:
1) Precipitate formation
2) Gas generation
3) formation of a non-dissociating compound
But in the reaction of NiCl₂(aq) with Zn(NO₃)₂(aq), no above requirement is met, so no reaction takes place.
NiCl₂(aq.) + Zn(NO₃)₂(aq). ------>No reaction
