Explanation:
The reaction is as follows:
2Mg(s) + O2(g) ---> 2MgO(s)
and the researcher said that 32 g of MgO was produced.
Stoichiometry:
28 g Mg × (1 mol Mg/24.305 g Mg) = 1.15 mol Mg
15 g O2 × (1 mol O2/15.999 g O2) = 0.938 mol O2
1.15 mol Mg × (2 mol MgO/2 mol MgO) = 1.15 mol MgO
1.15 mol MgO × (40.3044 g MgO/1 mol MgO) = 46.6 g MgO
0.938 mol O2 × (2 mol MgO/1 mol O2) = 1.88 mol MgO
1.88 mol MgO × (40.3044 g MgO/1 mol MgO = 75.6 g MgO
Based on these numbers, the amount of product after the reaction is much less than expected so these results don't seem to support the law of conservation of matter.
Answer:
60.42 grams
Explanation:
So, neon has a molar mass of 20.18 g/mol , which means that every mole of neon has a mass of 20.18 g so that means three of them is 60.42 grams

Carbon to hydrogen single, double or triple bond as intramolecular forces and is famous for forming ester linkages (intermolecular) as it is an alchol.
Answer:
The voltage delivered by a primary battery is unrelated to its size.
Circular lines on topographic map is called Contour lines these lines shown on two dimension map and depict elevation on the ground . the distance of each contour line is set to represent a certain level of elevation with zero being sea level . mostly map use distance between coutour lines is 10 m
