Answer:
![Sn_2O](https://tex.z-dn.net/?f=Sn_2O)
Explanation:
Hello,
In this case, given the mass of the sample and mass of tin we can compute the mass of oxygen via:
![m_O=0.534g-0.500g=0.034g](https://tex.z-dn.net/?f=m_O%3D0.534g-0.500g%3D0.034g)
Thus, by using the atomic bas of tin and oxygen we can compute their moles:
![n_{Sn}=0.500gSn*\frac{1molSn}{118.8gSn} =0.00421mol\\\\n_O=0.034gO*\frac{1molO}{16gO}=0.002125mol](https://tex.z-dn.net/?f=n_%7BSn%7D%3D0.500gSn%2A%5Cfrac%7B1molSn%7D%7B118.8gSn%7D%20%3D0.00421mol%5C%5C%5C%5Cn_O%3D0.034gO%2A%5Cfrac%7B1molO%7D%7B16gO%7D%3D0.002125mol)
Next, we need to divide both moles by the moles of oxygen as those are the smallest in order to compute the subscript in the chemical reaction:
![Sn=\frac{0.00421}{0.002125}=2\\ \\O=\frac{0.002125}{0.002125}= 1](https://tex.z-dn.net/?f=Sn%3D%5Cfrac%7B0.00421%7D%7B0.002125%7D%3D2%5C%5C%20%5C%5CO%3D%5Cfrac%7B0.002125%7D%7B0.002125%7D%3D%201)
Therefore, empirical formula of the oxide should be:
![Sn_2O](https://tex.z-dn.net/?f=Sn_2O)
Best regards.
Answer: It’s important because people go to the doctor when they don’t feel good, and sometimes it’s a virus, and sometimes it’s just bacteria.
Energy= 2381 joules
heat= Mass(kg) *change in temperature(K) * Cp
2381=0.155*(15)*Cp
Cp=1024 J/kg K
Answer:
How does an organisms DNA determine it's chances of survival:
Organisms with heritable (genetically determined) features that help them survive and reproduce in a particular environment tend to leave more offspring than their peers. If this continues over generations, the heritable features that aid survival and reproduction will become more and more common in the population
How does humans manipulate DNA of organisms to be benefit themselves:
Biotechnology is the use of biological techniques and engineered organisms to make products or plants and animals that have desired traits.
When it is filled with Helium it will expand and become more dense in the hot car. But when it becomes dense the gas molecules fly around in different directions, they collide with other objects and create pressure which can cause the balloon to pop.
