Answer:
2 electrons
E. neon
Explanation:
Metals lose electrons under certain conditions to attain a noble gas electron configuration. Magnesium has 12 electrons and its electron configuration is
1s² 2s² 2p6⁶ 3s²
When magnesium loses 2 electrons, it acquires the electron configuration of neon (10 electrons).
Answer:
it is a replacement reaction
Answer:
A
Explanation:
All of the other options are ways that could help the environment from the chemicals, but if they just continue to use the chemicals then it would hurt the environment
Answer:
Mass of
produced = 32 g
Explanation:
Calculation of the moles of
as:-
Mass = 82.4 g
Molar mass of
= 122.55 g/mol
The formula for the calculation of moles is shown below:
Thus,
From the reaction shown below:-

2 moles of potassium chlorate on reaction forms 3 moles of oxygen gas
So,
0.67237 moles of potassium chlorate on reaction forms
moles of oxygen gas
Moles of oxygen gas = 1 mole
Molar mass of oxygen gas = 32 g/mol
<u>Mass of
produced = 32 g</u>
