The correct answer is Lo.
The gravitational force between the two components is directly equivalent to the product of their masses and is inversely proportional to the distance separated between them. The largest planet in the solar system is Jupiter. It comprises 75 moons, and out of these moons, the four Galilean moons are very big in mass. These are Lo, Europa, Ganymede, and Callisto.
Of these Galilean moons, the Lo moon is very close to Jupiter. The Ganymede moon is the largest of all the Galilean moons, but it is situated very far from Jupiter in comparison to Lo. Thus, the force of attraction between the Lo and Jupiter is very high, it exhibits the greatest gravitational force with Jupiter.
Answer:
The unknown element is Carbon.
(a) X is Carbon, its oxide is of acidic nature
(b) C+ O2 → CO2
Explanation:
We are given an unknown element that reacts with oxygen.
X + O2 → XO2
It is given that the oxide XO2 turns blue litmus red which is shown by acids, so XO2 is an acidic oxide. Also X will be a Non metal because Non metallic oxide is Acidic in nature.
The Oxide XO2 is dissolving is water. The oxide upon reacting with water will give an Acid.
XO2 type of oxide is found in the 14th group of the periodic table generally
So we have options like C, Si and Ge as these only have the Acidic oxide.
But when it comes to reactivity with water Only Carbon satisfies the need so the unknown element X is C.
CO2 + H2O → H2CO3 which is an acid.
(a) Element X is Carbon (C), The nature of the compound formed is Acidic.
(b) The reaction given will be as follows
C+ O2 → CO2
Therefore the unknown element is Carbon.
Answer:
3.75 * 10^14
Explanation:
(3.0 * 10^17) / 800nm = 3.75 * 10^14hz ( have to have 17 and not 8 because its in nanometers)
Answer:
hope this helps have a amazing day! :)
Explanation:
Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions.
