Answer: what are the answers to the questions
Explanation:
A three dimensional circular shape would be a sphere :)
Answer:
mass Red Dye 40 = 0.0696 mg
Explanation:
aas found by means of quantitative methods of analysis of dyes in sports drinks:
⇒ [Red Dze 40] = 5.842 E-7 mol/L
analysis performed at a wavelength of 504 nm; value that is below the allowable limits for these drinks.
∴ mass of Red Dye ingested:
⇒ mass Red Dye = (5.842 E-7 mol/L)(496.43 g/mol)(1000 mg/g)(0.240 L)
⇒ mass Red Dye = 0.0696 mg
1. friction that’s all i know lol
The answer is :
2H₂O (l) ------>2H₂ (g) + O₂ (g)
That is ,
Oxidation number of oxygen increases in reaction :
2H₂O (l) ------>2H₂ (g) + O₂ (g)
In H₂O, oxidation number of oxygen is -2 but in O₂ molecule it is 0.
So, oxidation number of oxygen increases in this reaction that is from -2 to 0.
So in the reaction that is 2H₂O (l) ------>2H₂ (g) + O₂ (g) , oxidation number of oxygen increases .
