Answer:
1, mass is like how big it appears and weight could be small and be more weight then something with alot of mass
2, sorry i dont know
3, Jupiter you would weigh the most and the least is mars
4, the sun and if it was changed all the plants would eventually collide and go out of order
5, gravity, electricity and magnetism
Explanation:
Answer:
Using my (not very precise) periodic table, I get the mass of Ag as 107.87
Explanation:
This must be a combination of these two isotopes. So the % of the other isotope must be 48.16%.
To work with these percentages in an equation I'll use them as decimals.
So now I can start putting them into an equation:
107.87 = (
106.905
⋅
0.5184
) + (
x
⋅
0.4816
)
Because both of the isotope masses, multiplied by their percentage, would give us the overall average mass.
107.87 = 55.419552 ⋅ ( x ⋅ 0.4816
)
Worked out the brackets that we can work out, and then rearrange to give:
107.87 − 55.419552 = ( x ⋅ 0.4816 )
Again rearrange:
52.450448 = ( x ⋅ 0.4816 )
And final rearranging:
x = 52.450448 - 0.4816
x
=
108.909
(using same sig figs as given in question)
You probably want to work through that again using your periodic table value for Ag.
The answer is. :
nitrogen has 1s2 2s2 2p3 electronic configuration... it still needs 3e' to get octet structure and become stable.. hence valency=3.
Answer:
P₂ = 2.60 atm
Explanation:
Given data:
Initial pressure = 2.38 atm
Initial temperature = 25.0 °C
Final pressure = ?
Final temperature = 52.78°C
Solution:
Initial temperature = 25.0 °C (25.0+273 = 298 K)
Final temperature = 52.78°C (52.78+273 = 325.78 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
2.38 atm / 298 K = P₂/325.78 K
P₂ = 2.38 atm × 325.78 K / 298 K
P₂ = 775.35 atm. K /293 K
P₂ = 2.60 atm
