2. Based on what you read, how do sedimentary rocks differ from igneous rocks? A. Sedimentary rocks are formed by small pieces called sediments, while igneous rocks are formed by heat and pressure.
B. Sedimentary rocks are formed by small pieces called sediments, while igneous rocks are formed when hot molten lava is cooled down.
C. They are not different, in fact sedimentary rocks are formed the same way that igneous rocks are formed.
D. They have different colors and textures.

B

Explanation:

Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
