<span>Balancing the choices, we have as follows:
A. 3AgBr + GaPO4 → Ag3PO4 +GaBr3
B. 3H2SO4 + 2B(OH)3 → B2(SO4)3 + 6H2O
C. Fe + 2AgNO3 → Fe(NO3)2 + 2Ag
D. C2H4O2 +2O2 → 2CO2 + 2H2O
Therefore, the correct answers are option A and B. Hope this answers the question. Have a nice day.</span>
The electron is the only subatomic particle that has a negative charge
Answer:
v = 600 mph
Explanation:
Given data:
Distance cover by the plane = 3000 miles
Time taken by it = 5 hours
Velocity = ?
Solution:
Formula:
v = d/t
v = velocity
d = distance
t = time
Now we will put the values in formula.
v = 3000 miles/ 5 h
v = 600 mph
mph = miles per hour
Answer:
B: 3k+ + 3OH¯ + Fe3+ + 3KOH = Fe3(H) + + 3NO3¯
Explanation:
Potassium hydroxide (KOH) reacts with iron (III).
The normal balanced equation is;
Fe(NO3)3 + 3KOH = Fe(OH)3 + 3KNO3
Now the ionic equation will be;
3k+ + 3OH¯ + Fe3+ + 3KOH = Fe3(H) + + 3NO3¯
At STP
1L O₂ → 2L CO₂
xL O₂ → 5.0L CO₂
x=2.5 L
