Answer: A
Explanation: releases heat and can't be separated by physical means
Answer: 0.548J/g°C
Explanation:
Q = s × m × DeltaT
Q = Heat (J)
S = Specific Heat Capacity
M = mass (g)
DeltaT = Change in temperature (°C)
0.158Kg x 1000 = 158g
2.510J = s x 158g x (61°C-32°C)
2.510J/(158g x 29°C) = s
S = 0.54779.... J/g°C
S = 0.548 J/g°C
Answer:
2, 3, 1, 6.
Explanation:
2H3PO4 + 3Mg(OH)2 --> Mg3(PO4)2 + 6H2O
This is a neutralisation reaction because it is the reaction between acid and base to give a salt and water.
The RHS is the first to be balanced, Mg atom is first balanced, followed by the P atom.
This is because the excess O and H atoms can be balanced on the LHS.
Answer:
1.3 meters
Explanation: use newton third law equation.
Chlorine because that element has 17 electrons
