which of the following oxides will give the most basic solution when dissolved in water?
a) so2
b) co2
c) k2o
d) p4o10
e) so3
i know that the answer is c but can you explain how to solve this problem?

The correct answer is Option C.

Explanation:

Oxides are formed when a metal or a non-metal reacts with oxygen molecule. There are two types of oxides which are formed: Acidic oxides and basic oxides.

Acidic oxides are formed by the non-metals.

Basic oxides are formed by the metals.

From the given options:

Sulfur is the 16th element belonging to Group 16 and period 3 of the periodic table. This is a non-metal and will form acidic oxide.

Carbon is the 6th element belonging to Group 14 and period 2 of the periodic table. This is a non-metal and will form acidic oxide.

Potassium is the 19th element belonging to Group 1 and period 4 of the periodic table. This is a metal and will form basic oxide.

Phosphorus is the 15th element belonging to Group 15 and period 3 of the periodic table. This is a non-metal and will form acidic oxide.

Sulfur is the 16th element belonging to Group 16 and period 3 of the periodic table. This is a non-metal and will form acidic oxide.

Hence, the correct answer is Option C.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
