Evaporation because the salt would dissolve in the water then boil the water and it will evaporate leaving the salt left in the bowl
Answer:
4.15g
Explanation:
Balance the reaction:
2Mg + O2 = 2MgO
Find limiting reactant from the two, by dividing miles with coefficient
2.5/24.3 = 0.103 moles/2 = 0.0515
5/16 = 0.31 moles/2 = 0.156
0.0515 is small than 0.156, so limiting reactant is Mg
Compare the ratio of Mg with MgO
Ratio is 2:2
So same moles = 0.103 moles
Mass = moles x molar mass of MgO
Mass = 0.103 x 40.3
= 4.15g

Answer:
The stability of atoms depends on whether or not their outer-most shell is filled with electrons. If the outer shell is filled, the atom is stable. Atoms with unfilled outer shells are unstable, and will usually form chemical bonds with other atoms to achieve stability.
Explanation:
Neither N₂ or O₂ are greenhouses gases because they do not cause the greenhouse effect.
<h3>What are greenhouses gases?</h3>
Greenhouse gases trap heat in the atmosphere causing the temperature of the planet to rise.
Greenhouse gases cause the greenhouse effect.
<h3>What is the greenhouse effect?</h3>
The greenhouse effect is the warming up of the planet due to greenhouse gases.
Greenhouse gases include
- carbondioxide
- methane
- nitrous oxide and
- water vapour
So, neither N₂ or O₂ are greenhouses gases because they do not cause the greenhouse effect.
