Answer:
sorry
Explanation:
i'm not a chemistry student
but let me try
it is because the neutron of an atom is -
why the proton and electron is +and- (positive and negative)
so + and - = 0
A) mass / volume = density
m/6.00cm3 = 13.5939g/cm3
m = 13.5939g/cm3 • 6.00cm3
m = 81.6g
B) mass / volume = density
m/25.0cm3 = 0.702g/cm3
m = 0.702cm3 • 25.0g/cm3
m = 17.6g
1mL = 1cm3
Answer:
369.4 g.
Explanation:
- The chemical reaction of reacting hydrogen with oxygen to produce water is:
<em>H₂ + 1/2 O₂ → H₂O.</em>
- From the law of conservation of mass states that <em>the mass does not destroyed or created from nothing but it can converted from from to another one.</em>
- The mass of the reactants = the mass of the products
∴<em> The mass of hydrogen + the mass of oxygen = the mass of water.</em>
∴ The mass of oxygen = the mass of water - the mass of hydrogen = (416.0 g) - (46.6 g) = 369.4 g.
