Answer:
2.34g of NaCl
Explanation:
HCl(aq) + NaOH(aq) --------> NaCl(aq) + H2O(l)
Number of moles of HCl= 8 × 5/1000= 0.04 moles
Number of moles of NaOH= 2.4 × 20/1000= 0.048 moles
HCl is the limiting reactant
From the balanced reaction equation, 1 mole of HCl produced 58.5g of NaCl
0.04 moles of HCl will produce 0.04 × 58.5 = 2.34g of NaCl
1. 50Hz x .10m = 5 m/s
2. 20 m/s divided by .50m = 40Hz
3. 80 m/s divided by .20m = 400Hz
4. 120 m/s divided by .40m = 300Hz
5. 340 m/s divided by 440Hz = .77m
Answer:
C.
Fe goes from 0 to 2+, oxidation. It is reducing agent
N goes from 5+ to 2+, reduction. It is oxidizing agent
Explanation:
Oxidation number
Fe (s) has 0
FeSO4 has 2+
HNO3 N has 5+
NO N has 2+
Answer:
From left to right
Neutral
Acid
Base
Explanation:
So using HSAB theory hard and soft (Lewis) acids and bases.
OH - Is a Hard Base
H+ Strong Acid
