Answer:
predicting how a tech will interact with human tissue.
Explanation:
thats not really common except for in the medical field.
Molecular Formula: H5O5V-5
Answer:
CCl4 - Nonpolar
CH3OH - polar
NH3 - polar
CS2 - Nonpolar
Explanation:
One important thing that we should know is that polarity has to do with the presence of a resultant dipole moment in a molecule.
Dipole moment is a vector quantity, This means that its direction is also taken into account when discussing the dipole moment of molecules.
Hence, symmetrical molecules such as CS2 and CCl4 are non-polar even though they have polar bonds because their dipoles cancel out(zero resultant dipole moment).
On the other hand, NH3 and CH3OH are non-symmetrical molecules hence they possess an overall dipole moment and are polar molecules.
All problems are caused by a factor in which human beings play an important role in its cause.
Answer:
a) 0.13 g = 0.13X0.001 kg = 1.3 X 10⁻⁴ kg
b) 232 Gg = 232 X 1000000 kg = 2.32 X 10⁸ kg
c) 5.23 pm = 5.23 X 10⁻¹² m
d) 86.3 mg = 86.3 X 10⁻⁶Kg = 8.63 X 10⁻⁵Kg
e) 37.6 cm = 37.6 X 10⁻² m = 3.76 X 10⁻¹m
f) 54 = 5.4 X 10¹
g) 1 Ts = 10¹² seconds
h ) 27 ps = 27 X 10⁻¹² s= 2.7 X 10⁻¹¹ s
i) 0.15 mK = 1.5 X10⁻⁴ K
Explanation:
A scientific notation is a representation of any number which is very large or very small. It is simplification of writing a number.
The SI units of
i) weight = Kg
ii) length = meter
iii) time = second
iv) temperature = K
a) 0.13 g = 0.13X0.001 kg = 1.3 X 10⁻⁴ kg
b) 232Gg
1 Gg = 1000000 kg
232 Gg = 232 X 1000000 kg = 2.32 X 10⁸ kg
c) 5.23 pm
1 pm = 10⁻¹² m
5.23 pm = 5.23 X 10⁻¹² m
d) 86.3 mg
1mg = 10⁻⁶Kg
86.3 mg = 86.3 X 10⁻⁶Kg = 8.63 X 10⁻⁵Kg
e) 37.6cm
1 cm = 10⁻² m
37.6 cm = 37.6 X 10⁻² m = 3.76 X 10⁻¹m
f) 54 (no units)
54 = 5.4 X 10¹
g) 1 Ts = 10¹² seconds
h ) 27 ps
1 ps = 10⁻¹² s
27 ps = 27 X 10⁻¹² s= 2.7 X 10⁻¹¹ s
i) 0.15 mK
1mK = 10⁻³ K
0.15 mK = 1.5 X10⁻⁴ K
