<span>Every organism needs the energy to carry out a number of different processes, such as growth and reproduction. The energy is necessary for different metabolic processes and reactions inside the cells. Plants do not move around, so they don't need energy for movement, but they need the energy to develop, to grow, to produce food, to reproduce, and many other processes.</span>

1. 10.0 g of CaCO 3 on heating gave 4.4 g of CO 2 and 5.6 g of CaO. The observation is in agreement with the law of conserva

finlep [7]

Answer:

According to the law <br> Mass of reactants = mass of product, here <br> `underset(10 g)(CaCO_(3))rarr underset(4.4 g)(CO_(2))+underset(x)(CaO)` <br> Hence, x = 10 g - 4.4 g = 5.6 g <br> Which is mass of CaO.d
In the first compound <br> Hydrogen = 5.93 % <br> Oxygen = `(100-5.93)% = 94.07 %` <br> In the second compound <br> Hydrogen = 11.2 % <br> Oxygen `= (100-11.2)%=88.8%` <br> In the first compound the number of parts by mass of oxygen that combine with one part by mass of hydrogen `=(94.07)/(5.93)=15.86` parts ...
