The basic law of mass conservation states that, the total mass of products of a chemical reaction should be equal to the total mass of reactants in the same reaction.
Applying this law to the above problem, we find that:
Total mass of reactants = 46 + 96 = 142 grams
This means that the total mass of products (water + carbon dioxide) should be also 142 grams
Since 52 grams of water is produced, therefore,
mass of carbon dioxide = 142 - 52 = 90 grams
Answer:
Social justice aims to give individuals and groups fair treatment and an impartial share of social, environmental and economic benefits. The concept promotes the fair distribution of advantages and disadvantages within a society, regardless of background and status.
Environmental justice deals explicitly with the distribution of environmental benefits and the burdens people experience, at home, at work, or where they learn, play and spend leisure time. Environmental benefits include attractive and extensive greenspace, clean air and water, and investment in pollution abatement and landscape improvements. Environmental burdens include risks and hazards from industrial, transport-generated and municipal pollution.
A catalyst affects a chemical reaction by accelerating it. It also offers an alternative way for the reaction to happen that lowers the amount of energy needed.
