When looking at other planets for different life forms, scientists frequently look for a few key molecules that we depend on like water (H2O) and oxygen (O2). Because we are carbon-based life forms, they also look for carbon (C). Some scientists argue that we might not find life that is exactly like us on other planets and suggest looking for another element that is still similar to C. Which element below do you think this is? *

What is the molar mass of a gas that has density of 2.054 g/l

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
