Answer:

A.The Atlantic Ocean has more mid-ocean ridges than the Pacific Ocean so that keeps it growing larger.

Explanation:

Atlantic ocean is getting bigger because of the presence of spreading centers (divergent plate boundary). ... Pacific Ocean is getting smaller because the pacific plate is subducting along the subduction zones. Subduction zones are areas where old, dense plate subducts beneath a less dense plate.

Calculate the heat change in calories for melting 65 g of ice at 0 ∘c.

Genrish500 [490]

When ice melts, the physicals state changes from solid to liquid. The energy or the heat required (q) required to change a unit mass (m) of a substance from solid to liquid is known as the enthalpy or heat of fusion (ΔHf). The variables; q, m and ΔHf are related as:

q = m * ΔHf

the mass of ice m = 65 g

the heat of fusion of water at 0C = ΔHf = 334 J/g

Therefore: q = 65 g * 334 J/g = 21710 J

Now:

4.184 J = 1 cal

which implies that: 21710 J = 1 cal * 21710 J/4.184 J = 5188.8 cal

Hence the heat required is 5188.8 cal or 5.2 Kcal (approx)

A voltaic cell is based on the reduction of ag (aq) to ag(s) and the oxidation of sn(s) to sn2 (aq).

Annette [7]

Half-reaction for the cell's anode is given below:

Anode : $\\Sn(s) \rightarrow Sn^{2+} (aq) +2e^{-}$

The anode is defined as the electrode at which electrons leave the cell and oxidation occurs, and the cathode as the electrode at which electrons enter the cell and reduction occurs. The anode is usually the positive side.
