A species whose oxidation number increases in a reaction is oxidized (reducing reagents or reactant).
For example, balanced chemical
reaction: 2KClO₃ → 2KCl + 3O₂<span>.
</span><span>Oxygen in the
reactant state has oxidation number -2 (+1 + 5 + 3 · x = 0) and it is
oxidized to 0 (in molecule of oxygen) in the product state.</span>
First, if you want to get the amount of production from the equation, you need to use the units of mol. So, we need to know the molar mass of C which is 15.75/12=1.31 mol. Then we need to use the less part(O2) to get the production amount which is 0.116 mol. Then we can get the answer in units of g: 0.116*(12+16*2)=5.104 g.
Answer:
C)
Explanation:
M1V1 = M2V2
40.0ml*0.25M = M2*50.0ml
M2 = 40.0*0.25/50.0 = 0.20 M
Answer:
D. bromine
Explanation:
Highest electronegativity in the period has element closest to the *A group
K Ca Cu Br
Answer:
Explanation:
In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster. ... In liquids, particles are quite close together and move with random motion throughout the container.
