Limestone is used in industry as a raw material in the production of slaked Ca (OH) 2. 1) Write the equations of the chemical reactions that characterize the transformations carried out in the production process!

CaCO3 -> CaO -> Ca (OH) 2

The first reaction equation is how calcium oxide can be obtained from calcium carbonate.

The second reaction equation - how calcium oxide can be obtained from calcium oxide.

Ibelieve the answer is d

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.
