<u>Given data:</u>
Volume of solution measured = 0.0067 L
<u>To determine:</u>
The number of significant figures
<u>Explanation:</u>
Significant figures are the number of digits that accurately describe a measured value.
As per the rules:
All non-zero digits are significant
Leading zero's i.e. the zero's after a decimal which comes before a non-zero digit are not significant
Hence in the given value 0.0067, there are 2 significant figures (6 &7)
Answer:
El cambio ocurre a causa de que los iones reaccionan y producen un cambio en la disposición de los átomos que se encuentran presentes en el indicador.
300g because it’s more water to heat, meaning how easy would it be to boil a cup of water? Easy. What about a pool? See what I mean, bigger the area lesser the warmth it gets.
* Mole ratio:
C2H4 + 3 O2= 2 CO2 + 2 H2O
1 mole C2H4 --------------- 2 moles H2O
8.00 moles C2H4 ---------- ?
8.00 x 2 / 1 => 16 moles of H2O
Therefore:
1 mole --------- 22.4 L at ( STP)
16 moles ------- ?
16 x 22.4 / 1 => 358.4 L
hope this helps!
