2 NaOH + H2SO4 → 2 H2O + Na2SO4<br> How many grams of water are produced from 203.50 grams of H2S04?
ddd [48]

Answer:

m_{H_2O}=74.8gH_2O

Explanation:

Hello there!

In this case, according to the given chemical reaction, it is possible to realize there is a 1:2 mole ratio of sulfuric acid to water; thus, given the mass of the former and its molar mass (98.07 g/mol), it is possible to determine the mass of produced water as shown below:

m_{H_2O}=203.50gH_2SO_4*\frac{1molH_2SO_4}{98.07gH_2SO_4}*\frac{2molH_2O}{1molH_2SO_4}  *\frac{18.02gH_2O}{1molH_2O}\\\\m_{H_2O}=74.8gH_2O

How many moles of CO2 are there in 2.55 x 10<br><br> 18<br><br> molecules of CO2?
cluponka [151]

Answer: There are 4.23\times 10^{-6}moles  of CO_2

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given molecules}}{\text {Avogadros number}}

\text{Number of moles}=\frac{2.55\times 10^{18}}{6.023\times 10^{23}}=0.423\times 10^{-5}moles

Thus there are 4.23\times 10^{-6}moles  of CO_2

lbvjy [14]

Answer:

Oxygen

Explanation:

 · Air decolorization makes use of chromophores’ instability on oxygen to decolorize the oil by air-oxidizing pigments. For example, the carotenoid and chlorophyll in the oil are very unstable because of their structure, which is easy to be discolored under the action of oxygen. However, air decolorization leads to thermal oxidation of the oil, too.
