Answer:
The Second Law of Thermodynamics poses an insurmountable problem for ... More time will make things worse for the Darwinist, not better. ... error fail-safe and proof-reading devices utilized for quality control, assembly ... No one really supports the idea that the sun + non life = life
Explanation:
Answer:
Your question is not interpreted very well, but as regards what is observed, SO2 is not the formula for sulfur oxide, the formula for sulfur oxide is SO since the valence used in sulfur would be +2 and oxygen -2 therefore the sum of these valences would be equal to zero, therefore it would be the correct thing considering the true equation as SO
Explanation:
There are also sulfur dioxide, or sulfur trioxide, which is usually used in the formation of tertiary salts such as copper sulfate.
sulfur trioxide and sulfur dioxide are synonymous with sulfate or sulphite
Answer:
Molecular formula = C₄H₁₂O₂
Explanation:
Given data:
Percentage of hydrogen = 13.80%
Percentage of carbon = 51.02%
Percentage of oxygen = 35.18%
Molecular formula = ?
Solution:
Number of gram atoms of H = 13.80 / 1.01 = 13.6
Number of gram atoms of O = 35.18 / 16 = 2.2
Number of gram atoms of C = 51.02 / 12 = 4.25
Atomic ratio:
C : H : O
4.25/2.2 : 13.6/2.2 : 2.2/2.2
2 : 6 : 1
C : H : O = 2 : 6 : 1
Empirical formula is C₂H₆O.
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = C₂H₆O = 46 g/mol
n = 88 / 46
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2 (C₂H₆O)
Molecular formula = C₄H₁₂O₂
5N force was applied to an object if 35 j of work was done and the object moved 7 m
A force is an effect that can alter an object motion according to physics and an object with mass can change its velocity or accelerate as a result force and also force is as push or pull and work done by the force on an object means assuming that direction of the force is parallel to the displacement of the object
Then the formula is
W = f × d
Where f is the magnitude of force and d is the displacement of the object
Then W = 35 J is the work done and
d = 7m is the displacement of the object
So rearrange the equation then
F = 35/7 = 5N
5N force was applied to an object if 35 j of work was done and the object moved 7 m
