Answer:

24.3049 amu

Explanation:

Atomic mass of magnesium = percentage average of its isotopes

= 23.9850 x .7899 + 24.9858 x 0.10 + 25.9826 x .1101

= 24.3049 amu

How does oxidation differ from reduction
Dima020 [189]

Answer:

See the explanation below, please.

Explanation:

In redox reactions (oxide reduction) the transfer of electrons between compounds occurs.

 In oxidation, electrons are lost (positive charge increases). Example:

Mg ---> Mg2 + + 2 e- (passes from Mg ° to Mg 2+)

On the other hand in the reduction, electrons are gained (negative charge increases or the positive one increases). Example:

Cl2 + 2e- ---> 2 Cl- + 2 e- (passes from Cl ° to Cl-)

) Experimental evidence indicates that the nucleus of an atom
geniusboy [140]

Answer:

A (contains most of the mass of the atom)

Evidence has it that a proton is about 2000 times as massive as an electron.

And there is usually multiple protons and neutrons in the nucleus

From what I just said, you can say that B is wrong

C however is also wrong because protons have a +charge and neutrons are neutrle which means you always have a charge > (greater than) 0

And D is wrong because electrons (which are not in the nucleus) have a neg charge. and protons have a + charge and are in the nucleus

So your answer is A

Hope it helped

Which of the following can cause muscle fatigue ?
dezoksy [38]

Answer:

The correct answer is -all of the above.

Explanation:

Muscle fatigue is a reduced ability in work capacity caused by work itself. It is known that altering oxygen is contracting skeletal muscle affects performance. Reduced O2 supply increases the rate of muscle fatigue.

The lactic acid is accumulated as it forms rapidly but the breaking of the lactic acid is slow down, which causes muscle fatigue. Less ATP and glycogen in muscle results in fatigue as the muscle is not able to generate energy to power contractions and therefore contributes to muscle fatigue.
