Answer:
Chemical Properties
Explanation:
Chemical properties are properties that are observed during chemical reactions. Some examples of chemical properties are reactivity, flammability and chemical stability.
Answer:
Carbon dioxide reacts with limewater (a solution of calcium hydroxide, Ca(OH) 2), to form a white precipitate (appears milky) of calcium carbonate, CaCO 3.
Hope it helps you! :)
Answer:
I'm pretty sure its the one that says very little at the beginning but if I get it wrong I'm sorry
One mole (abbreviated mol) is equal to 6.022×1023 molecular entities (Avogadro's number), and each element has a different molar mass depending on the weight of 6.022×1023 of its atoms (1 mole). The molar mass of any element can be determined by finding the atomic mass of the element on the periodic table.
Particles are smaller, a reactant would be exposed to more cobalt atoms. Causing the reaction to happen quicker than with larger particles.
