Sr N(e⁻)=38
Sr²⁺ N(e⁻)=38-2=36
36e⁻
Au2S is =<u><em> 426 g/mol</em></u> for molar mass
Answer:
There are 3 bonding pairs of electrons
Explanation:
For every bond there is one bonded pair of electrons. NH₃ has three N-H bonds, so has three bonding pairs of electrons along with a lone pair of electrons
True.
For example: Sodium oxide and Nitric acid; both compounds contain oxygen.
Answer:
The potential energy the apple had due to its height is converted to kinetic energy
Explanation:
When an apple falls from the tree to the ground, its <u>energy of position stored as gravitational potential energy is converted to kinetic energy</u>, the energy of motion, as it falls. When the apple hits the ground, kinetic energy is transformed into heat energy.
