Displacement = √(3² + 4²)
Displacement = 5 meters north east

Velocity = displacement / time
Velocity = 5 / 35
Velocity = 0.14 m/s northeast

The button batteries in small devices like watches are commonly composed of silver-zinc or mercury-zinc batteries. The reaction

Answer:

The mercury button battery line notation is:

        Zn⁰| Zn²|| , HgO| Hg⁰||

Explanation:

Mercury batteries either use

pure mercury(II) oxide (HgO)—which is called mercuric oxide

or a mixture of HgO with manganese dioxide (MnO2) which is as the cathode.

Anode has two half reactions:

The first step is an electrochemical reaction step:

Zn + 4OH− → Zn(OH)4−2 + 2e−[3]

cathode has a half reaction :

HgO + H2O + 2e− → Hg + 2OH−[3]

+0.0977 V  standard potential is of this reaction.

which is followed by a chemical reaction step:

Anode consists of oxidation:

Zn+2OH>ZnO+H2O+2e

which gives an overall anode half-reaction of:

Zn + 2OH− → ZnO + H2O + 2e−[3]

Therefore,

The overall reaction for the battery is:

Zn + HgO → ZnO + Hg

A gas of 190 mL at a pressure of 74 atm can be expected to change its pressure when its volume changes to 30.0 mL. Express its n
kozerog [31]

Answer : The new pressure of the gas will be, 468.66 atm

Explanation :

Boyle's Law : This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

P\propto \frac{1}{V}     (At constant temperature and number of moles)

or,

P_1V_1=P_2V_2

where,

P_1 = initial pressure of the gas = 74 atm

P_2 = final pressure of the gas = ?

V_1 = initial volume of the gas = 190 ml

V_2 = final volume of the gas = 30 ml

Now we put all the given values in the above formula, we get the final or new pressure of the gas.

74atm\times 190ml=P_2\times 30ml

P_2=468.66atm

Therefore, the new pressure of the gas will be, 468.66 atm

A gas occupies 2.22 l at 3.67 atm. what is the volume at 1.94 atm?
Iteru [2.4K]
According to Boyle's law, volume is inversely proportional to pressure. thus P=k/V
Therefore PV=k
P1V1=P2V2
In the question above,
P1=3.67atm
P2=1.94atm
V1=2.22L
V2=?
Thus substituting for the values in the gas equation;
3.67atm*2.22L=1.94atm*V2
V2=3.67atm*2.22L/1.94atm
=4.21L
