Question

List the number of each type of atom on the right side of the equation MgS(aq)+2CuCl2(aq)→2CuS(s)+MgCl2(aq) Enter your answers separated by commas (the order of the numbers is the same as the order of the elements on the left side of the equation).

Answer #1

In each of the following balanced oxidation-reduction equations,
identify those elements that undergo changes in oxidation number
and indicate the magnitude of the change in each case.
Part A
I2O5(s)+5CO(g)→I2(s)+5CO2(g)
What are the elements changing the oxideation number?
Enter your answers as chemical symbols separated by a comma.
Indicate the magnitude of the change in this case.
Part B
2Hg2+(aq)+N2H4(aq)→2Hg(l)+N2(g)+4H+(aq)
What are the elements changing the oxideation number?
Enter your answers as chemical symbols separated by a comma.
Indicate the...

!. What are the coefficients for this equation so that it
balances? HCl(aq) + Al(s)------ H2(g) +
AlCl3(aq); (Hint- the coefficient add to 13).Just write
your answer separated by commas(for example 2,1,4,6)
2. If someone measures out 2.75g of magnesium solid, how many
moles is this? In order to answer, yo will need to use the molar
mass given in the periodic table.
3. Whic is limiting H2(g) or O2(g)?How
much water actually forms?

Suppose we take the interval [−4,8] and divide it into 4 equal
subintervals. Find the width Δn of each subinterval:
If we name the endpoints of the subintervals x0,
x1, x2, x3 and x4, with
x0 on the left and x4 on the right, find the
values of these endpoints and list them in ascending order. (Enter
your answers in a comma-separated list.)

Suppose the spinner shown to the right is spun once, to determine
a single-digit number, and we are interested in the event E that

Identify the acid (A), base (B), conjugate acid (CA) and
conjugate base (CB) in each of the following reactions: Then,
provide your answer in the space below. Do this in short-hand by
identifying the role of each substance from left to right in the
equation, using A for acid, B for base, CA for conjugate acid and
CB for conjugate base. Then, list these in order. As an example,
your answer to this question for the reaction
Base + Acid...
