The 18o:16o abundance ratio in some meteorites is greater than that used to calculate the average atomic mass of oxygen on earth
Colt1911 [192]

Answer: The average mass of the oxygen atom in these meteorites will be greater than the terrestrial oxygen atom.

Explanation:

Average atomic mass of an element is defined as the summation of the product of the atomic masses and fractional abundances of its isotopes.

Equation to calculate the average atomic mass will be given by:

\text{Average atomic mass}=\sum_{i=1}^n(\text{Atomic mass of an isotopes})_i\times (\text{fractional abundance})_i

We are given that the abundance ratio of the oxygen in meteorites is more than the terrestrial oxygen atom.

As, from the formula, average atomic mass of an element is directly proportional to the fractional abundance of the isotopes. Hence, with increase in the abundance, the average atomic mass also increases.

Therefore, the average mass of the oxygen atom in these meteorites will be greater than the terrestrial oxygen atom.

I suck in science so pls help<br> thx
CaHeK987 [17]

Answer:

Sometimes it is not an increase in force that is desired, but an increase in  

distance or speed.  Take a baseball bat as an example.  A bat is a class 3  

lever, meaning the effort is in the middle.  This means that it has a  

mechanical advantage of less than one.  However, when the bat is swung,  

the end of the bat is travelling at a much higher speed than the location at  

which the batter is holding it.  This allows the ball to leave the bat at a  

much higher speed than it would with a class one or two lever.

The combination of oxygen with other substances to produce new chemical products is called
Flauer [41]

Answer:

                 The combination of oxygen with other substances to produce new chemical products is called <u>Oxidation</u>.

Explanation:

                     Oxidation reactions are defined as,

In terms of Inorganic chemistry:

                 (i) <u>Removal of Electrons: </u>

                            Example:  Mg  →  Mg²⁺  +  2 e⁻

                (ii) <u>Addition of Oxygen:</u>

                            Example:  2 Mg  + O₂  →  2 MgO

In terms of Organic chemistry:

                (i) <u>Addition of Electrons: </u>

                            Example:  Cl₂  +  2 e⁻   →   2 Cl⁻

                (ii) <u>Addition of Hydrogen:</u>

                            Example:  H₂CCH₂  +  H₂    →   H₃CCH₃
