Answer:

Nickel (II) to solid nickel.

Explanation:

Hello,

In this case, the placed species are nickel (II) sulfate $NiSO_4$ , zinc sulfate $ZnSO_4$ and solid iron $Fe$ . Now, as the nickel sulfate is more reactive than the zinc sulfate, it will experience the following reduction half-reaction from nickel (II) to solid nickel:

$Ni^{2+}+2e^--->Ni^0$

Nevertheless, it is possible that the zinc might experience the same reduction reaction from zinc (II) to solid zinc as well.

Best regards.

A precipitate forms when mixing solutions of sodium fluoride (NaF) and lead II nitrate (Pb(NO3)2). Complete and balance the net

Margarita [4]

Answer:

Pb^2+(aq) + 2F-(aq) → PbF2(s)

Explanation:

Step 1: Data given

sodium fluoride = NaF

lead(II)nitrate Pb(NO3)2

Step 2: The unbalanced equation

NaF(aq) + Pb(NO3)2(aq) → PbF2(s) + NaNO3(aq)

Step 3: Balancing the equation

NaF(aq) + Pb(NO3)2(aq) → PbF2(s) + NaNO3(aq)

On the left side we have 2x NO3 (in Pb(NO3)2), on the right side we have 1x NO3 (in NaNO3). To balance the amount of NO3 we hvae to multiply NaNO3 on the right side by 2.

NaF(aq) + Pb(NO3)2(aq) → PbF2(s) + 2NaNO3(aq)

On the left side we have 1x Na (in NaF), on the right side we have 2x Na (in 2NaNO3). To balance the amount of Na we have to multiply NaF on the left side by 2. Now the equation is balanced.

2NaF(aq) + Pb(NO3)2(aq) → PbF2(s) + 2NaNO3(aq)

Step 4: Calculate net ionic equation

The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will , after canceling those spectator ions in both side, look like this:

2Na+(aq) + 2F-(aq) + Pb^2+(aq) + 2NO3-(aq) → PbF2(s) + 2Na+(aq) + NO3-(aq)

Pb^2+(aq) + 2F-(aq) → PbF2(s)

why does every human measurement have uncertainty associated with it? Why must we manage the uncertainty during calculations?

dimulka [17.4K]

Because there are many numbers of the human measurement . we must manage the uncertainly doing calculations because we can know what we are calculating.

Solnce55 [7]

Complete Question:

In the first paragraph, the words “disrobed,” “unveiling” and “deconstructed” primarily serve to (a) highlight the negative connotations that laser technology currently has, (b) emphasize the extensive reach of laser technology; (c) demonstrate the inherently unknowable characteristics of objects, even with laser technology; (d) implicitly compare lasers to other forms of technology

Answer:

(b) emphasize the extensive reach of laser technology;

Explanation:

The use of the word disrobed and deconstructed from the passage emphasizes the extensive reach of laser technology. Even without looking up the dictionary meaning of the two words, one can easily deduce that the passage is a pro-laser technology one.

The passage presents the use of the laser technology in solar exploration.
It also show its use by ecologists.
