Alfred Wegener
proposed the continental drift theory in
four reasons. One, he hypothesized that the continents were once a giant
continent. Two, he observed that there are fossils found of the same kind in
the different locations. Three, he found that the edge of opposing continents
somehow fits if they are combined, almost like a puzzle. And four, there are
glacial scars that are left behind by a larger glacial continent. His greatest
weakness of Alfred Wegeners’ continental drift theory was he could not explain
what kind of force that caused this continents to move far from each other.
Explanation:
chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. All the matter in the universe is composed of the atoms of more than 100 different chemical elements, which are found both in pure form and combined in chemical compounds
Applications of iron oxide nanoparticles include terabit magnetic storage devices, catalysis, sensors, superparamagnetic relaxometry (SPMR), and high-sensitivity biomolecular magnetic resonance imaging (MRI) for medical diagnosis and therapeutics.
The volume of water that will be produced from the reaction will be 6.3 mL
<h3>Stoichiometric calculation</h3>
From the equation of the reaction:
The mole ratio of hydrogen sulfate to sodium hydroxide is 1:2.
Mole of hydrogen sulfate = 0.50 x 350/1000 = 0.175 moles
Mole of 15 grams sodium hydroxide = 15/40 = 0.375 moles
Thus, hydrogen sulfide is the limiting reagent.
Mole ratio of hydrogen sulfide to water = 1:2.
Equivalent mole of water = 0.175 x 2 = 0.35 moles
Mass of 0.35 moles of water = 0.35 x 18 = 6.3 grams.
1 gram of water = 1 ml.
Thus, 6.3 grams of water will be equivalent to 6.3 mL

The conversion for cm³ to ml is:
1 cubic centimetre = 1 millimetre
Therefore,
2 cubic centimetres = 2.0 millimetres
And so, your answer is E (but the cm should be cm³).
