its answer A....that's the answer is
Explanation:
The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10-7 m, which is red).
The resistance of the appliance is 64.1 Ω.
<u>Explanation:</u>
As per the Ohm's law, which states that the electric current is in direct proportion to the voltage and is in inverse proportion to the resistance. It is given by the expression as,
V = IR
Where V is the voltage (V) = 150.0 V
I is the current (amps) = 2.34 amps
R is the resistance (ohm) or Ω = ?
Now we have to rearrange the equation to get the resistance as,
Now we have to plug in the values as,
= 64.1 Ω
So the resistance of the appliance is 64.1 Ω.

Figure 1 provides the rawest and most accurate data.
Explanation:
Answer:
The atom that is oxidized is Zn.
Explanation:
Reducing agents reduce other atoms or species by being oxidized themselves. Oxidation is a loss of electrons. In the equation, the Zn atom originally has an oxidation state of zero (neutral). On the right side of the equation, Zn is part of the ionic compound zinc sulfate, which is composed of the Zn(2+) cation and the SO4(2-) anion. The Zn(2+) ion is positive, which means it must have lost electrons (which have a negative charge), and was therefore oxidized from the neutral atom Zn(s).
Answer:
a) H3PO4 (aq) + 3 KOH (aq) → K3PO4 (aq) + 3 H2O (l)
b)
AgNO3 (aq) + NaCl (aq) → AgCl (s) + NaNO3 (aq)
c)
Ca(OH)2 (s) + 2 H3PO4 (aq) → Ca(H2PO4)2 (s) + 2 H2O (l)
d)
2 KI (aq) + Pb(NO3)2 (aq) → 2 KNO3 (aq) + PbI2 (s)
e)
3 H2SO4 (aq) + 2 Al(OH)3 (s) → 6 H2O (l) + Al2(SO4)3 (aq)
All balanced equation for each reaction!!
