Answer:
Electrons are the only subatomic particles that have a negative charge.
the atomic mass of argon is 39.948. That means that one mole of argon weighs 39.948 grams (39.948 g/mol).
A. attraction is the interest you have in a person in other words liking them.
B. repulsion is the digust you have in someone or something.
C. rotation: rotating on a axis or center.
Answer:
Convergent boundaries form when two crustal plates are colliding. ... The subducting plate is being recycled as it begins to melt at about 100 kilometers. The water soaked oceanic plate forms molten rock that collects in magma ... If the break is along hundreds of kilometers of fault line a megathrust earthquake occurs.
Explanation:
Answer:
0.2042 M is the original concentration of 
(aq) in the titrating solution.
Explanation:
Mass of 
= 0.217 g
Moles of 
1 mole of have 2 mole of As and 1 mole of 
have 1 mole of As.
So, from 1 mole of we will have 2 moles of
Then from 0.001096 mol of :
of
According to reaction, 1 mole of reacts with 2 mole of cerium (IV) ions,then 0.002192 mol of
of cerium (IV) ions.
Volume of the acidic cerium{IV) sulfate = 21.47 ml =0.02147 L
1 mL = 0.001 L
![[Ce^{4+}]=\frac{0.004384 mol}{0.02147 L}=0.2042 M](https://tex.z-dn.net/?f=%5BCe%5E%7B4%2B%7D%5D%3D%5Cfrac%7B0.004384%20mol%7D%7B0.02147%20L%7D%3D0.2042%20M)
0.2042 M is the original concentration of (aq) in the titrating solution.
