A. The pH indicates how acidic or basic a
solution is.
Answer:
a. True
Explanation:
The data curve for OCI-/H3O appears to be similar to C2H3O2-/H3O because protons have not dissociated with conjugate base. This conjugate base is strong and hold proton in solution while acids try to dissociate it.
The balanced chemical reaction is written as:
<span>2Al2O3 = 4Al + 3O2
We are given the amount of aluminum oxide used in the reaction. This will be the starting point for the calculations. We do as follows:
26.5 mol Al2O3 ( 3 mol O2 / 2 mol Al2O3 ) = 39.75 mol O2 produced</span>
Size
The Sun is 1,390,000 km in diameter. That compares with 12,756 km for diameter of the Earth. In other words, the diameter of the Sun is over 100 times the diameter of the Earth.
In June, 2004, Venus passed in front of the Sun, as seen from the Earth. Since the diameter of Venus is only slightly less than that of Earth (12,104 km)
Mass
The mass of the Sun is about 2 x 1030 kilograms (2 followed by 30 zeros). It is one of the larger stars in our Milky Way galaxy. The median size of stars in our galaxy is less than half the mass of the Sun. In comparison, the Earth is 6 x 1024 kg. This means that the mass of the Sun is over 300,000 times greater than that of the Earth.
