New substances are formed by chemical reactions. When elements react together to form compounds their atoms join to other atoms using chemical bonds. For example, iron and sulfur react together to form a compound called iron sulfide. Hopefully this will help you decide...

Lithium Chloride releases 37 kJ of energy per mole when dissolved in water.
Energy released = 0.25 x 37
= 9.25 kJ
= 9,250 J
Temperature change of water may be calculated using
ΔH = mCpΔT
Cp = 4.18 J/g
ΔT = 9,250 / (200 x 4.18)
ΔT = 11.1 °C
1) use energy from food
2) get rid of wastes
3) maintain
Answer:
a) σa−σb−σc−σd=0
Explanation:
The parallel plate capacitor is the one in which two metal plates are connected in parallel with some distancing among them. The electric field from both plates is denoted by E = σ / 2ϵ0. The σ is the charge density. The Electric field in plate I will vanish when the surface charge of σa is positive and rest of the charges are negative. The correct option is a.
