Answer:
New varieties usually come about in 3 ways: sexual crossing between existing varieties; volunteer seedlings that are “found”; and genetic mutations of existing apple wood.
Explanation: something like that
Cars rust because when metal comes into contact with water or some sort of water form, it will make the surface wet. If the metal is wet for too long, it will start to soak up the water, therefore making it rusty. The salt will also rust a car. It does this because the mix of carbon dioxide and oxygen in the salt will eat away at the car, making it rust faster. Hope this helps!
Answer:
![m_{FeCl_2}=0.652gFeCl_2](https://tex.z-dn.net/?f=m_%7BFeCl_2%7D%3D0.652gFeCl_2)
Explanation:
Hello there!
In this case, according to the given information and the chemical reaction, whereby iron and hydrochloric acid react in a 1:2 mole ratio, it is firstly necessary to calculate the moles of iron (II) chloride from each reactant in order to figure out the limiting reactant:
![n_{FeCl_2}=2.45gFe*\frac{1molFe}{55.845gFe}*\frac{1molFeCl_2}{1molFe}=0.0439molFeCl_2\\\\ n_{FeCl_2}=1.5L*0.25\frac{molHCl}{L} *\frac{1molHCl}{36.46gHCl}*\frac{1molFeCl_2}{2molHCl}=0.00514molFeCl_2](https://tex.z-dn.net/?f=n_%7BFeCl_2%7D%3D2.45gFe%2A%5Cfrac%7B1molFe%7D%7B55.845gFe%7D%2A%5Cfrac%7B1molFeCl_2%7D%7B1molFe%7D%3D0.0439molFeCl_2%5C%5C%5C%5C%20%20n_%7BFeCl_2%7D%3D1.5L%2A0.25%5Cfrac%7BmolHCl%7D%7BL%7D%20%2A%5Cfrac%7B1molHCl%7D%7B36.46gHCl%7D%2A%5Cfrac%7B1molFeCl_2%7D%7B2molHCl%7D%3D0.00514molFeCl_2)
In such a way, we infer the maximum moles of FeCl2 product are yielded by HCl, for which it is the limiting reactant. Finally, we calculate the grams of product by using its molar mass as shown below:
![m_{FeCl_2}=0.00514molFeCl_2*\frac{126.75gFeCl_2}{1molFeCl_2} \\\\m_{FeCl_2}=0.652gFeCl_2](https://tex.z-dn.net/?f=m_%7BFeCl_2%7D%3D0.00514molFeCl_2%2A%5Cfrac%7B126.75gFeCl_2%7D%7B1molFeCl_2%7D%20%5C%5C%5C%5Cm_%7BFeCl_2%7D%3D0.652gFeCl_2)
