Question 1 of 5 - POS
In an experiment, two students timed how long salt took to dissolve in water under the four conditions shown below.
Condition 1 No stirring and no heat
Condition 2. Stirring and no heat
Condition 3: No stirring with heat
Condition 4: Stirring and heat
The students carefully recorded the time it took for the salt to dissolve under each set of conditions. However, they forgot to label which condition

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

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).

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
