The most unusual characteristic of Uranus is _____.

Chemistry
1 answer:
fiasKO [112]3 years ago
6 0

Answer:

the axis is tilted at 98 degrees

Explanation:

Uranus is blue, not green; it has an atmosphere of hydrogen and helium, not methane.  While it does have an icy cold temperature, that's not a very unusual characteristic for an outer planet.  However, the tilt of the axis is unusual; no other planet is tilted almost completely on its side!

Salsk061 [2.6K]
10) Arsenic is a chemical agent which was used in preserving dead bodies in the past. It is mainly a formaldehyde mixture with coloring agents to give a dead body the look of life. Sylvester was a third mummy that was embalmed with arsenic in the late 1800s and is now on exhibit at Ye Olde Curiosity Shop in Seattle, Washington. His mummified body showed an extremely unusual since the remains weighed approximately 80 lbs when a body is composed of 70-80% water, after dehydration, the weight should be about 20-30% the premortem weight. The solution was also used during Civil War to preserve dead bodies <span>as the dead were being shipped home from the battlefield.

A chemical reaction that is first-order in X is observed to have a rate constant of 1.50 × 10–2 s–1. If the initial concentratio
elena-s [515]

Answer:

0.053 M is the concentration of X after 196 seconds.

Explanation:

Initial concentration of the X = [A_o]=1.0 M

Time taken by the sample, t = 196 s

Final concentration of the X after t = [A] =?

Rate constant of the reaction = k = 1.50\times 10^{-2} s^{-1}

Formula used :

[A]=[A_o]\times e^{-kt}

where,

Now put all the given values in this formula, we get

[A]=[1.0M]\times e^{-1.50\times 10^{-2} s^{-1}\times 196 s}

[A]=0.053 M

0.053 M is the concentration of X after 196 seconds.

Which of the following statements would be accepted as a valid criticism of
murzikaleks [220]

Answer:

There are three significant problems:

The Flatness Problem:

WMAP has determined the geometry of the universe to be nearly flat. However, under Big Bang cosmology, curvature grows with time. A universe as flat as we see it today would require an extreme fine-tuning of conditions in the past, which would be an unbelievable coincidence.

The Horizon Problem:

Distant regions of space in opposite directions of the sky are so far apart that, assuming standard Big Bang expansion, they could never have been in causal contact with each other. This is because the light travel time between them exceeds the age of the universe. Yet the uniformity of the cosmic microwave background temperature tells us that these regions must have been in contact with each other in the past.

The Monopole Problem:

Big Bang cosmology predicts that a very large number of heavy, stable "magnetic monopoles" should have been produced in the early universe. However, magnetic monopoles have never been observed, so if they exist at all, they are much more rare than the Big Bang theory predicts.
