1 mm (millimeter) = 0.000001 km (kilometer)
12.5 mm = <span>0.0000125 km
1 mm = </span><span>0.00001 hm (hectometer)
12.5 mm = </span><span>0.000125 hm
1 mm = </span>0.001 m (meter)
12.5 mm = 0.0125 m
1 mm = 0.1 cm (centimeter)
12.5 mm = 1.25 cm
So the only one of the answer choices that doesn't equal 12.5 mm is 0.00125 hm, since 12.5 mm is <span>0.000125 hm.
Answer:
</span><span>0.00125 hm

The statement above is TRUE.
The periodic table refers to the table of chemical elements, in which the elements are arranged in order of their atomic numbers in such a way that, similar elements appear in vertical columns. Elements in the same column usually have similar atomic structures and similar chemical properties. Thus, the periodic table allows one to easily compared the properties of one element to that of another one depending on the placement of the elements in the periodic table.<span />
The rate of dissolving would increase with:
<span>C) more surface area
</span><span>D) high temperature
</span><span>E) a lot of agitation

B nonmetals that’s your answer :)
The element X is titanium.
According to the question, the percentage by mass of Cl in XCl4 is 75.0%.
The percentage by mass is obtained from;
Mass of element in the compound/molar mass of compound * 100
Hence;
Let the mass of the unknown element be X
75 = 142/X + 142 * 100
75 (X + 142) = 142 * 100
75X + 10650 = 14200
75X = 14200 - 10650
X = 14200 - 10650/75
X = 47
Hence, X is titanium.
