This would be silver. Silver has a density of 10.5 g/cm^3.
Hope this helps~
The molar concentration of the solution is calculated as follows
find the moles of NaCl used to make the solution
moles = mass/molar mass
mass =7.83 g
molar mass =58.5 g/mol
moles = 7.83 g/ 58.5 g/mol = 0.134 moles
molarity ( concentration in mol/l) = number of moles/volume in liters
volume in liters = 90ml/1000 =0.09 liters
molarity is therefore = 0.134 moles/0.09 L =1.49 M
Answer:
Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide. Al2O3 is an example of an amphoteric oxide.
Answer:
5 atoms of hydrogen will be found in the products
Explanation:
5 atoms of hydrogen will be found in the products becuase the law of conservation of mass states that mass is neither created nor destroyed in chemical reactions.
