Hi there!
To solve, we can use dimensional analysis to convert from molecules to grams.
We must use Avogadro's number (6.02 × 10²³) in converting from molecules to moles.
After converting, multiply by the atomic mass, or grams per mole.
Answer:
Yes
Explanation:
An object's weight can change, depending on its location, relative to the object of discussion. For example, we don't notice the change, but the farther away we are from Earth's core, the less we weigh. This means one would weigh more in a valley than they would on a mountain. The formula for gravity is F=G((msub1)(msub2)/r^2), where F is the force of attraction, G is the universal gravitational constant, msub1 is the mass of the first object, msub2 is the mass of the second object, and r is the distance between the two objects.
Answer:
Explanation:
2AgNO₃ + Sn ⇄ Sn( NO₃)₂ + 2Ag
Ag⁺/Ag = .80 V
Sn⁺²/Sn = - .14 V
Hence Ag will be reduced and Sn will be oxidised . Hence the reaction will take place . YES .
2 ) 2 electrons are transferred .
3 )
2Ag⁺ + 2e = 2Ag
Sn = Sn⁺² + 2e
---------------------------
2Ag⁺ + Sn = Sn⁺² + 2Ag .
Explanation:
mass number= atomic number + no of neutrons
35= 17 + no of neutrons
no of neutrons = 18
