Your answer should be C. bend when passing from air to water. Hope this helps! =^-^= If you need an explanation, just let me know.
The answer is C, a catalyst. This is due to the fact that catalysts are substances that can be used to speed up a reaction by lowering the activation energy required. However, the catalyst itself is not actually used up during the reaction.
"As the molecules in a sample move faster the temperature reading will be lower" is not true.
<span>grape juice
pOH = -log[1.4*10⁻¹⁰]</span>≈9.6
pH=14-pOH=14-9.6=4.4
orange juce
pH= -log[1.8*10⁻⁴]=3.7
Orange juice has lower pH, so it is more acidic.
Its 4.08 i hope hopefully its helpful
