Answer:
a)the ionic radius of phosphorus
Explanation:
phosphorus=2.8.6
for phosphorus to become stable(2.8.8) it gains two electrons thus the ionic radious increases bcz of the gained electrons
Make sure there are the same number of atoms of each element on either side.
1) Check each one.
2) If one's out of balance, alter the equation to balance it and go back to 1)
3) When everything's balanced, you're finished!
We have 1 Na on the left and 2 Na on the right here. We'll need another NaOH to balance it:
2 NaOH + H₂SO₄ > Na₂SO₄ + H₂O
Now O is out of balance. There's 6 on the left and 5 on the right. We'll need more H₂O:
2 NaOH + H₂SO₄ > Na₂SO₄ + 2 H₂O
Fortunately H is in balance. S is also in balance here, so looks like we did it!
Need any more help?
You use the equation q=mcdeltaT delta t=the chang in temp m=the mass of water and c=the specific heat capacity which for water is usually 4.18kJ
q is the amount of energy which you are trying to figure out
im sorry that i dont know the overall units for the equation but hope this helps you
:) :)
Answer:
The laws of the universe are for all observers, and it was shown that the velocity of light in spacetime will be the same regardless of the subject's speed.
Explanation:
The principle outlines how things behave in time and space, so it could be used to model anything from black hole life to light shifting due to the gravitational, as well as the action of the terrestrial Planets in its orbit. Einstein's most popular hypothesis has far-reaching ramifications.
Explanation:
The order of positive mesomeric effect (+M) is as follows
F>Cl>Br>I.
This implies that electron density in the respective Halobenzene is of the order
Fluorobenzene > Chlorobenzene > Iodobenzene.
This means that electrophilic aromatic substitution will also follow the same order, more the electron density more will be chances of electrophilic aromatic substitution. This means fluorobenzene is more reactive than chlorobenzene toward electrophilic aromatic substitution
However, methyl group is attached in ring, beacuse of starric hindrance, chloromethylbenzene is more reactive than fluoromethylbenzene.
