A. It has made the spread of information faster and easier
Quantitative measurements are numerical values, they involve amounts and units like measuring things. Qualitative observations appeal to the five senses, like what does the interaction look and sound like
Answer:
0.00369 moles of HCl react with carbonate.
Explanation:
Number of moles of HCl present initially =
moles = 0.00600 moles
Neutralization reaction (back titration): 
According to above equation, 1 mol of NaOH reacts with 1 mol of 1 mol of HCl.
So, excess number of moles of HCl present = number of NaOH added for back titration =
moles = 0.00231 moles
So, mole of HCl reacts with carbonate = (Number of moles of HCl present initially) - (excess number of moles of HCl present) = (0.00600 - 0.00231) moles = 0.00369 moles
Hence, 0.00369 moles of HCl react with carbonate.
C.) Ionic bond is formed between that...
Answer:
373.15 K
Explanation:
Given data:
Temperature in degree Celsius = 100°C
Temperature in kelvin scale = ?
Solution:
To convert the degree Celsius into kelvin scale we add the given degree Celsius into 273.15.
100°C +273.15 = 373.15 K
