The atomic structure of an atom is well explained experimentally by different experiments like Rutherford's experiment etc
Based on these experiments it was determined that the atoms contains a central part known as nucleus which contains the positively charged sub atomic particles protons and neutral sub atomic particles neutron.
There is empty space around the nucleus in which negatively charged subatomic particles are found known as electrons.
So answers are
a) protons
b) neutrons
c) electrons
Answer:
3.08 g of Oxygen .
Explanation:
2Mg + O₂ = 2MgO
2 mole 1 mole
molecular weight of Mg = 24
2 mol of Mg = 48 g
48 g of Mg reacts with 32 g of oxygen
4.62 g of Mg will reacts with 3.08 g of Oxygen .
Ok I will and your welcome
First you must write a balanced chemical equation.
C3H8 + 5O2 --> 3CO2 + 4H2O
From there, we can set up the stoichiometry equation to solve.
g O2= 70.2 g C3H8 X (1 mol C3H8/44.0962g C3H8) X (5 mol O2/1 mol C3H8) X (31.998g O2/1 mol O2)
Now solve, and you should get 254.7 g O2. Hope this helped!
