The balanced equation would be:
2HCl + Mg(HCO3)2 —> MgCl2 + 2CO2 + 2H2O
If it’s hydraulic turbine then it’s potential and kinetic energy and if it’s a thermal process then heat energy from the fuel burnt runs the turbine
Well the reason why the water valve was because of the force of gravity. Without the force of gravity the water would have flown so if you had to try to move the water up the waterfall you would have to fight the force of gravity
1) d
2) b because the independent variable is the thing you change/control in an experiment
3) c because the dependent variable is the thing being measured in an experiment
4)hmm it might be d, as c and a are both correct as different sized feeders would make it an unfair test and different types of food would as well
5) c
6) a
7) b obviously because if he activated them at different times then the ones activated last would have an advantage
