Answer:
2. Igneous rocks can weather, creating sediments that form sedimentary rocks
Explanation:
Sedimentary rocks are formed from Igneous rocks when rocks are broken down by weathering.
The statement is not entirely accurate. The sum of potential energy and kinetic energy does not directly equate to thermal energy. Therefore this statement is False.
Thermal energy refers to the total internal energy of a system due to the random motion of its particles, which includes both kinetic energy and potential energy related to the interactions between particles.
While kinetic energy is associated with the movement of particles, potential energy accounts for forces between particles or their positions in a field (like gravitational potential energy).
The direct summation of kinetic and potential energy does not give the complete picture of thermal energy, as it does not consider other factors like molecular interactions, vibrations, and rotations within a substance.
Thermal energy encompasses all forms of energy within a system arising from particle motion and interactions, making the given statement false.

Answer:
CaCO3 + 2HCL -> CO2 +H2O + CaCl2
Explanation:
When balancing an equation, it is important to first ensure that the chemical formulas in the equation are correct. In the above equation, the first modification required is for CaCl to be corrected to CaCl2. This is because the calcium ion has a charge of 2+ which has to be balanced by 2 chloride ions, each of charge 1-
Next, the overall atoms of the equations should be balanced. The number of atoms of each element on the side of reactants should be equal to their number on the side of the products. In this case, the number of HCL molecules should be 2.
Before balancing equation:
Reactants: Ca: 1, C: 1, O: 3, H: 1, Cl: 1
Products: Ca: 1, C: 1, O: 3, H: 2, Cl: 1
After balancing equation:
Reactants: Ca: 1, C: 1, O: 3, H: 2, Cl: 2
Products: Ca: 1, C: 1, O: 3, H: 2, Cl: 2
(1) CuCO3(s) ==> CuO(s) + CO2(g)
(2) 2KClO3(s)==>2KCl(s) + 3O2(g)
(3) AgNO3(aq) + KCl(aq) ==>AgCl(s) + KNO3(aq)
(4) H2SO4(aq) + 2KOH(aq)==> K2SO4(aq) + 2H2O(l)
