The answer is an acid.
That is a substance that gives up a proton during a chemical reaction, raising the hydrogen ion concentration of water, is most appropriately called an acid.
Acid is a substance that gives protons in its aqueous solution, and that the hydrogen ion concentration of that aqueous solution .
Answer:
(d) the ion with 24 electrons, 30 neutrons, and a 3+ charge ... (b) the ion with 36 electrons, 35 protons, and 45 neutrons.
Answer:aluminum
Explanation:aluminum is a precious metal which means that it can be changed into a liquid solid or gas
Ethene react with oxygen at a molar ratio:
Convert the quantity of each reactant supplied to number of moles of particles:
The question stated not whether both reactants were used up in this process. Thus start by testing the assumption that e.g., ethene was used up while some oxygen gas were left unreacted (ethene as the <em>limiting </em>reagent.) Under this assumption, the relative availability of the two species, and (as seen in the balanced chemical equation) shall satisfy the relationship
In other words,
Evaluating the expression with data given in the question yields approximately , which does satisfy the relationship. Hence the assumption holds and ethene is the limiting reactant.
The quantity of a reactant produced in a chemical reaction is related to its stoichiometric (of relating to proportions) relationship with the limiting reactant (or any of the reactants in case of more than one limiting reactant.) For this scenario, given the molar ratio ,
