CuSO₄+ Zn = Cu + ZnSO₄
1 mole Zn ---------> 1 mole Cu
3.8 mole Zn ------> ?
moles Cu = 3.8 x 1 / 1
= 3.8 moles of Cu
hope this helps!
C the immigration rate is higher than the emigration rate
<span>Which of the following gases would be most likely to experience ideal behavior at high pressures?
a. F2
b. Ne
c. C2H6
Yes. The answer is (b) Ne (Neon). This is because monoatomic gases such as neon do not experience </span><span>intermolecular attractions and thus most likely to be close to ideal gases behavior. Not only that, Neon is a noble gas and is unreactive. </span>
Answer:
1.0625 g
Explanation:
Number of moles in 5g of NH4NO3 = 5.0g/80g/mol = 0.0625 moles
Again the balanced reaction equation is;
NH3 + HNO3 → NH4NO3
So,
1 mole of NH3 yields 1 mole of NH4NO3
x moles of NH3 yields 0.0625 moles of NH4NO3
x = 0.0625 moles of NH3
Mass of NH3 = number of moles * molar mass
Mass of NH3 = 0.0625 moles * 17g/mol
Mass of NH3 = 1.0625 g
Electric current is when electrons start to flow around a circuit. We use an ammeter to measure it and it is measured in amps
Potential difference (also called voltage) is how big the push on the electrons is. We use a voltmeter to measure it and it is measured in volts.
Resistance is anything that resists an electric current. It is measured in ohms”.
(Words: volts, amps, ohms, voltage, ammeter, voltmeter).
