n three trials of a reaction to determine the concentration of a sodium hydroxide solution, the average volume of 0.1255 mol/L sulfuric acid was 19.97 mL to neutralize 20.00 mL of the base. What was the concentration of the sodium hydroxide solution? Determine the original pH value of the base.

not clear

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
