Igneous rock is formed by the cooling of magma and lava. Sedimentary rock is formed over different minerals building on top of each other overtime creating layers.
Answer:
The mass of silver carbonate precipitated is 5.18 grams.
Explanation:
Molarity of the silver nitrate solution = 0.671 M
Volume of the silver nitrate solution = 56.0 mL
![1 mL = 0.001 L\\56.0 mL = 56.0\times 0.001 L=0.0560 L](https://tex.z-dn.net/?f=1%20mL%20%3D%200.001%20L%5C%5C56.0%20mL%20%3D%2056.0%5Ctimes%200.001%20L%3D0.0560%20L)
Moles of silver nitrate = n
![Molarity=\frac{\text{Moles of compound}}{\text{Volume of solution in Liters}}\\\\0.671 M=\frac{n}{0.0560 L}\\n=0.671 M\times 0.0560 L=0.0376 mol](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7B%5Ctext%7BMoles%20of%20compound%7D%7D%7B%5Ctext%7BVolume%20of%20solution%20in%20Liters%7D%7D%5C%5C%5C%5C0.671%20M%3D%5Cfrac%7Bn%7D%7B0.0560%20L%7D%5C%5Cn%3D0.671%20M%5Ctimes%200.0560%20L%3D0.0376%20mol)
Moles of silver nitrate used = 0.0376 mol
![K_2CO_3+2AgNO_3\rightarrow Ag_2CO_3+2KNO_3](https://tex.z-dn.net/?f=K_2CO_3%2B2AgNO_3%5Crightarrow%20Ag_2CO_3%2B2KNO_3)
According to the reaction, 2 moles of silver nitrate gives 1 mole of silver carbonate, then 0.0376 moles of silver nitrate:
![=\frac{1}{2}\times 0.0376 mol=0.0188 \text{mol of }Ag_2CO_3](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%200.0376%20mol%3D0.0188%20%5Ctext%7Bmol%20of%20%7DAg_2CO_3)
Moles of the silver carbonate formed = 0.0188 mol
Molar mass of silver carbonate = 275.7453 g/mol
Mass of silver carbonate :
![=275.7453 g/mol\times 0.0188 mol=5.1840 g\approx 5.18 g](https://tex.z-dn.net/?f=%3D275.7453%20g%2Fmol%5Ctimes%200.0188%20mol%3D5.1840%20g%5Capprox%205.18%20g)
The mass of silver carbonate precipitated is 5.18 grams.
The correct option is B. The alkali metals combine directly with halogens forming high melting point crystalline solids that have high negative enthalpies of formation. The entalphy of formation for lithium bromide is the highest and the values decrease down the group, thus, lithium is the most stable while cesium is the least stable.
