The correct answer is option C. The outcome of putting litmus paper into bleach would be that red paper turns blue, blue paper does not change. Domestic bleach is a strong base it typically has a pH of 11 to 13. So when testing for pH, it would really go with the basic characteristics.
Answer:
Denaturation causes loss of enzyme activity which is necessary for biochemical reaction.
Hence many biological process(respiration,digestion,excretion) won't work properly.
Explanation:
Enzymes : These are biological catalyst made of proteins.E.g Pepsin, tyrosine (human digestion)
Denaturation: loss of Quaternary ,tertiary and secondary structure of proteins and nucleic acid because of extreme conditions of temperature , pressure ,pH etc.
When denaturation occur enzymes loss their specific structure, so they can't carry out various life process (e.g respiration, digestion ,excretion).
Enzymes are involved in all biological reaction and work only at optimum temperature ,pH and pressure(human body condition ).
By increasing the size of cells
Answer:
102 g Al₂O₃
Explanation:
To find the mass of Al₂O₃, you need to (1) convert grams Al to moles Al (via molar mass), then (2) convert moles Al to moles Al₂O₃ (via mole-to-mole ratio from reaction coefficients), and then (3) convert moles Al₂O₃ to grams Al₂O₃ (via molar mass). It is important to arrange the ratios in a way that allows for the cancellation of units. The final answer should have 3 sig figs to reflect the given values.
Molar Mass (Al): 26.98 g/mol
Molar Mass (Al₂O₃): 101.96 g/mol
4 Al + 3 O₂ ---> 2 Al₂O₃
54.0 g Al 1 mole 2 moles Al₂O₃ 101.96 g
-------------- x ----------------- x ----------------------- x ---------------- = 102 g Al₂O₃
26.98 g 4 moles Al 1 mole
