Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.
Observations in the scientific method lead to questions which need answers. The hypothesis is a testable argument presented in scientific method to address a question. Experiments (often with controls and variables) are formulated in the experimental method for evaluating theories. Hope this helps ✨
Answer:
equal to
Explanation:
This question is depicting the LAW OF CONSERVATION OF MASS/MATTER, which states that matter can neither be created nor destroyed. Hence, in an isolated system, the original mass of the reactants must be EQUAL TO the final mass of the products formed.
In other words, the law states that no matter the change in chemical composition of the reactants in a chemical process, the mass does not change or it remains constant.
Answer:
S + 4 Cl2
Explanation:
Sulphur - S
1 mol of Sulphur = S
Chlorine = Cl2
4 moles of Chlorine = 4Cl2
4S + 2Cl2
Incorrect option
S + 4 Cl2
Correct option
S + 2Cl2
Incorrect option
S + Cl2
Incorrect option
She can conclude that it is an exothermic reaction: the reaction releases energy, notably thermal energy.
