Answer:
this is an example
Explanation:
Yes, the balloon will burst at room temperature.
As we know that, 480 x 7/8 = 420 is the maximum Stretching capacity of the balloon.
b) V. / T. = V/T
Where
V = 480 ml and T. = 5 C(278 K)
And T= 30 C( 303 K)
V = V.T/T.
V = 480 x 303/278
V = 523.1 ml
b)V./V=T./T ?
Where
V = 480 ml and
T = 5 C (278 K)?
And V = 420 ml
T=T.V./V
=278 x 480/420
= 317.17 k
Therefore the balloon will burst at the temperature of 317.17 k

Answer:
HfCl3
Explanation:
Step 1
Divide the percent by mass of each element by its relative atomic mass
Hf- 62.2/178.5, Cl-37.4/35.5
0.348, 1.054
Step2
Divide through by the lowest ratio
0.348/0.348, 1.054/0.348
1, 3
Therefore the empirical formula is HfCl3
Answer:
Na+ is smaller than Na because, it has given away one electron because of which the electron shielding gets stronger due to more protons and less electrons. Whereas, Cl- is larger than Cl because it has gained an extra electron and so, the no.07/12/2010
