Explanation:
litmus paper
Because it will just tell if the solution is acidic or basic, it won't tell the pH
Answer:
M of Al=33.09g or 0.0331kg
Explanation:
Heat Energy= specific heat*mass*change in temperature
H=M*C*T
make M subject of the formula
M=H/CT
M=685J/0.90J/g°C*(45°C-22°C)
M=685J/0.90J/g°C*23°C
M=685J/20.7J/g
M=33.09g or 0.0331kg
Ok the ML (the 3rd number) is not legit because the ML value can only be from -L to L (the second value)
