Explain the difference between mass and weight. Why is your weight on the Moon one-sixth that on Earth?

Chemistry
1 answer:
Trava [24]1 year ago
6 0

The weight on moon is  (1/6)^t^h of the weight at earth because the value of g reduces to  (1/6)^t^h on moon.

Mass is a measure of the amount of matter in an object, and Weight is the amount of force that gravity exerts on an object.

What is the relation between mass and weight?

  • The main difference between mass and weight is: Mass is a scientific measure of the amount of matter an object is made of. Regardless of where you are at any given moment, the mass is constant.
  • However, weight is actually a description of gravity on an object.
  • The relation between mass (m) and weight (W) is W = m * g.      Thus, weight is defined as the product of mass and gravitational acceleration (g)
  • As weight depends on the value of gravitational acceleration, it changes as the value of g changes.
  • Now, the value of g at moon is (1/6)^t^h of the value of g at earth, that means the weight on moon is  (1/6)^t^h of the weight on earth.

How many protons, electrons, and neutrons does the following isotope contain? ^{18} \text{F}^{-} 18 F −
melomori [17]
Isotope ¹⁸F⁻ contains:
1) p⁺ = 9; number of protons.
Fluorine has a<span>tomic number Z = 9 (total number of protons).
2) e</span>⁻<span> = 10; </span>number of electrons.<span>
In element number of electrons and protons are the same, because element has neutral charge, but because in this example, fluorine is anion with negative charge, it has one electron more.
3) n</span>° = 9; number of neutrons.
<span>Mass number A = 18 is total number of protons and neutrons in a nucleus, so number of neutrons is A-Z = 18-9=9.</span>

Antoine Lavoisier burned metals in sealed jars. What is your prediction of his experimental results?
Aliun [14]

Answer:

The mass of the jar and contents remained the same after the metal was burned.

Explanation:

My prediction about the experimental results is that  the mass of the jar and contents remained the same after the metal was burned in the jar.

This is compliance with the law of conservation of mass which states that in a chemical reaction, matter is neither created nor destroyed by bonds are rearranged for new compounds to form.

  • In compliance with this law, it is expected that the mass of the jar and its content will remain the same before and after the reaction.
  • No new material was added and no material was removed from the jar.

Assuming acid strength relates directly to number of O atoms bonded to the central atom, rank H₂N₂O₂ [or (HON)₂]; HNO₃ (or HONO₂
Elenna [48]

For Less number of oxygen atoms will be less acidic. Therefore, the rank will be.... So there is 1 oxygen atom bonded to each of the 2 nitrogen atoms.

For HNO3 or {HONO}2. So there are 3 oxygen atoms bonded to the nitrogen.

For HNO2 or HONO. So there are 2 oxygen atoms bonded to the nitrogen.

Less number of oxygen atoms will be less acidic. Therefore, the rank will be...

HNO3>HNO2>H2N2O2

Acid strength is the tendency of an acid, symbolized by the chemical formula, to dissociate into a proton, and an anion, The dissociation of a strong acid in solution is effectively complete, except in its most concentrated solutions.

The strength of a weak organic acid may depend on substituent effects. The strength of an inorganic acid depends on the atom’s oxidation state to which the proton may be attached. Acid strength is solvent-dependent. For example, hydrogen chloride is a strong acid in an aqueous solution but is a weak acid when dissolved in glacial acetic acid.
