The gas 0.735/0.523=1.405moles.
so 1.405 times of gas is present than what was at the start. 0.523moles of argon took up 0.723L(723mL) so 1.405 times as much gas would take 1.405 times as much space. so the volume would be ,
1.405*0.723=1.015L
4.8 g/cm3 with sig figs since it's mass/volume you divide 76 grams by 16 cm3
You can predict it by measuring the weight of the spherical object and measuring the liquid (mL) and subtracting finding the volume
Answer:
a)Anode-Zinc
Cathode - Iron
b) At the anode;
Zn(s) -----> Zn^+(aq) + 2e
At the cathode;
Zn^+(aq) + 2e -----> Zn(s)
c) ZnSO4
d) The electrode which is connected to the positive post of the battery is the anode.
The electrode which is connected to the negative post of the battery is the cathode.
Explanation:
Electroplating is an electrolytic process in which a metal is used to cover the surface of another metal. The plating substance is the anode while the plated substance is the cathode. The electrolyte is a salt of the plating metal.
The anode of an electrolytic cell must be maintained at a positive potential with respect to the cathode hence it is connected to the positive terminal of the battery. The cathode must be maintained at a negative potential hence it is connected to the negative terminal of the battery.
Answer:
because the force depends upon the product of both masses and the square of the distance between them, whereas the planet's acceleration depends on just the mass of the Sun and the square of the distance between the Sun and planet.
