Standard Molar Volume is the volume occupied by one mole of any gas at STP. Remember that "STP" is Standard Temperature and Pressure. Standard temperature is 0 &176:C or 273 K. Standard pressure is 1 atmosphere or 760 mm Hg (also called "torr"). 1 mole of any gas at STP occupies 22.4 liters of volume.
Answer:
![V_{CO_2}=16.0mL](https://tex.z-dn.net/?f=V_%7BCO_2%7D%3D16.0mL)
Explanation:
Hello,
In this case, given that the same temperature and pressure is given for all the gases, we can notice that 16.0 mL are related with two moles of carbon monoxide by means of the Avogadro's law which allows us to understand the volume-moles relationship as a directly proportional relationship. In such a way, since in the chemical reaction:
![2CO(g)+O_2(g)\rightarrow 2CO_2(g)](https://tex.z-dn.net/?f=2CO%28g%29%2BO_2%28g%29%5Crightarrow%202CO_2%28g%29)
We notice two moles of carbon monoxide yield two moles of carbon dioxide, therefore we have the relationship:
![n_{CO}V_{CO}=n_{CO_2}V_{CO_2}](https://tex.z-dn.net/?f=n_%7BCO%7DV_%7BCO%7D%3Dn_%7BCO_2%7DV_%7BCO_2%7D)
Thus, solving for the yielded volume of carbon dioxide we obtain:
![V_{CO_2}=\frac{n_{CO}V_{CO}}{n_{CO_2}} =\frac{2mol*16.0mL}{2mol}\\ \\V_{CO_2}=16.0mL](https://tex.z-dn.net/?f=V_%7BCO_2%7D%3D%5Cfrac%7Bn_%7BCO%7DV_%7BCO%7D%7D%7Bn_%7BCO_2%7D%7D%20%3D%5Cfrac%7B2mol%2A16.0mL%7D%7B2mol%7D%5C%5C%20%5C%5CV_%7BCO_2%7D%3D16.0mL)
Best regards.
Answer:
= 2.659 g NaCl
Explanation:
Molarity of a substance is given by the formula;
Molarity = moles/Volume in liters
Thus;
Number of moles = Molarity × volume in liters
= 1.3 M × 0.035 L
= 0.0455 Moles
But, the molar mass of NaCl is 58.44 g/mol
The mass of NaCl is therefore;
= 0.0455 g × 58.44 g/mol
<u>= 2.659 g NaCl</u>
Answer:
Explanation:
Together with her husband, she was awarded half of the Nobel Prize for Physics in 1903, for their study into the spontaneous radiation discovered by Becquerel, who was awarded the other half of the Prize. In 1911 she received a second Nobel Prize, this time in Chemistry, in recognition of her work in radioactivity.
Answer:
Atoms form chemical bonds to make their outer electron shells more stable. The type of chemical bond maximizes the stability of the atoms that form it. Covalent bonds form when sharing atoms results in the highest stability. Other types of bonds besides ionic and covalent chemical bonds exist, too.
