Answer:
6000N
Explanation:
Force = Mass x Acceleration
= 3000 x 2
= 6000 kg m/s^2 or 6000N
At decomposition of solid substance with formation of gas leads to increase in an entropy. For example,
60°C
NH₄NO₂(s) = N₂(g) + 2H₂O(l)
true
i mean it can be true and it cant at the same time. i mean medicine doesn't always work on a person. but it is said that medicine that is in powder form is more efficient.
but i believe its D or A
Answer:
Water has the greatest ΔEN
ΔEN H₂O → 3.4 - 2.1 = 1.3 Option D.
Explanation:
We should find the Electronegativity data in the Periodic table for all the elements:
C : 2.6
O: 3.4
H: 2.1
S: 2.6
N: 3.0
a. ΔEN CO₂ → 3.4 - 2.6 = 0.4
b. ΔEN H₂S → 2.6 - 2.1 = 0.5
c. ΔEN NH₃ → 3 - 2.1= 0.9
d. ΔEN H₂O → 3.4 - 2.1 = 1.3
Pd has an
anomalous electron configuration. Write the observed electron configuration of
Pd.
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2
3d^10 4p^6 4d^10
The electron configuration
shown above is the original configuration of Pd. Here is the anomalous electron
configuration.
1s^2 2s^2 2p^6 3s^2 3p^6 3d^10
4s^2 4p^6 4d^10 or (Kr) 4d^10
