During a nuclear reaction mass is converted into energy
Equation 1
weight of 2 bolt = 6.75 weight of washer
Equation 2
mass = W/g
Where
g = 9.8m/s^2
mass of box of 2 bolt = weight of 2 bolt x 2 bolt pcs/box/9.8 m/s^2
mass of box of 2 bolt = 6.75 weightwasher x 2 bolt pcs/box
if there are 144 pcs of bolts/box
mass of box of 2 bolt= 6.75 weight of washer x 144/9.8m/s^2
mass of box of 2 bolt = 972 weight of washer /9.8m/s^2
=99.18 weight of washer s^2/m
Answer:
C.) 2,1,2
Explanation:
You have to balance the equation by getting the number of elements on the left and right side to equal. Before balancing there is one more oxygen on the left side than the right side. You have to change the coefficient in front of H2O to fix this, and that means adding a "2" in front of the H2 to get that to equal as well.
You end up with 2H₂+10₂→ 2H₂O
Answer:
The possible source of errors as regard the Procedure are:
- The final temperature was measured before the temperature stopped changing
- The cap of the calorimeter was not closed immediately after mixing
- temperatures where not measured right before mixing
