The force of the wind breaks down the particles (the amount of force depends on the type of rock eg sedimentary, metamorphic, igneous)
Answer:
The answer should be A
Explanation:
because the definition of a subscript is that they indicate the number of atoms of an element present in am molecule or formula unit.
Answer:
The concentration of the solution is 5.8168 × mol.
Explanation:
Here, we want to calculate the concentration of the solution.
The unit of this is mol/dm^3
So the first thing to do here is to calculate the number of moles of the solute present, which is the number of moles of AlCO3
The number of moles = mass/molar mass
molar mass of AlCO3 = 27 + 12 + 3(16) = 27 + 12 + 48 = 87g/mol
Number of moles = 33.4/87 = 0.384 moles
This 0.384 moles is present in 660 L
x moles will be present in 1 dm^3
Recall 1 dm^3 = 1L
x * 660 = 0.384 * 1
x = 0.384/660 = 0.00058168 = 5.8168 * 10^-4 mol/dm^3
<span>Incomplete combustion will occur when there is not enough oxygen to allow the fuel to react completely to produce carbon dioxide and water. It also happens when the combustion is quenched by a heat sink, such as a solid surface or flame trap.
The answer is C. Carbon dioxide.

<h2>Answer : Option A) Field lines enter Earth near the North Pole.</h2><h2>Option D) Field lines circle Earth from east to west. and </h2><h2>
Option E) A compass can lead a hiker to the geographic North Pole.</h2><h3>Explanation :</h3>
A) The earth's magnetic field lines are observed to enter near the north pole because it is the magnetic pole; which is the point were the magnetic field lines are vertical and enter the earth.
D) The magnetic field line are believed to start from east and end in west similar to the meridians.
E) The Earth is considered as a magnet which seems to interact with other magnets in a way, so the north end of a compass magnet is drawn to align with the Earth's magnetic field.
