An excited state refers to an atom with electrons at a higher energy level. More than necessary and a ground state is when all atom's electrons are in their lowest orbital possible
Thus, sound will travel at a slower rate in the denser object. If sound waves of the same energy were passed through a block of wood and a block of steel, which is more dense than the wood, the molecules of the steel would vibrate at a slower rate. Thus, sound passes more quickly through the wood, which is less dense.
Answer:
The mass of water 
= 39.18 gm
Explanation:
Mass of iron 
= 32.5 gm
Initial temperature of iron 
= 22.4°c = 295.4 K
Specific heat of iron 
= 0.448 
Mass of water =
Specific heat of water 
Initial temperature of water 
= 336 K
Final temperature after equilibrium 
= 59.7°c = 332.7 K
When iron rod is submerged into water then
Heat lost by water = Heat gain by iron rod
( - ) = ( - )
Put all the values in above formula we get
× 4.2 × ( 336 - 332.7 ) = 32.5 × 0.448 × ( 332.7 - 295.4 )
= 39.18 gm
Therefore the mass of water = 39.18 gm
Answer:All six of the ions contain 10 electrons in the 1s, 2s, and 2p orbitals, but the nuclear charge varies from +7 (N) to +13 (Al)
Explanation:
hope this helped if it did may i have brainliest
Answer:
Hydrogen and Chlorine
Explanation:
They are both an example in univalent atoms, because of their nature to form only one single bond.
I wasn't able to find another example, hope it helped! :)
