Answer:
C. 1.3 mol
Explanation:
PV = nRT
where P is absolute pressure,
V is volume,
n is number of moles,
R is universal gas constant,
and T is absolute temperature.
Given:
P = 121.59 kPa
V = 31 L
T = 360 K
R = 8.3145 L kPa / mol / K
Find: n
n = PV / (RT)
n = (121.59 kPa × 31 L) / (8.3145 L kPa / mol / K × 360 K)
n = (3769.29 L kPa) / (2993.22 L kPa / mol)
n = 1.26 mol
Round to two significant figures, there are 1.3 moles of gas.

taste bitter
have high pH's - more than 7
feel slippery
Explanation:
Bases are certain metallic oxides, metallic hydroxides and aqueous ammonia. They are substances that produces hydroxyl ions in solutions.
- The aqueous solutions of many bases have a bitter taste
- Bases generally have a soapy or slippery feel.
- They have a high pH reading on the scale.
- They are good electrolytes
- The are used for making soaps in industries.

Explanation:
Hello,
In this case, given the reaction:
When 23.0 g of oxygen react and 26.1 g of water are yielded, given the law of conservation of mass which states the mass of reactants must equal the mass of products:
The mass of hydrogen turns out:
