Free File Fillable Forms is an electronic version of IRS paper forms. Free File Fillable Forms does not include any elaborate cross-checking or question-and-answer formats (such as is found in many of the Free File Software packages), instead it is a simple fill-in-the blank format (however, it does perform math calculations).
Moscovium (115 Mc) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no known stable isotopes. The first isotope to be synthesized was 288 Mc in 2004. There are five known radioisotopes from 286 Mc to 290 Mc. The longest-lived isotope is 290 Mc with a half-life of 0.65 seconds.

In 2002 Sergiy Vilkomir proposed reinforced condition/decision coverage (RC/DC) as a stronger version of the MC/DC coverage criterion that is suitable for safety-critical systems. [7] [8] Jonathan Bowen and his co-author analyzed several variants of MC/DC and RC/DC and concluded that at least some MC/DC variants have superior coverage over RC ...
Gaen has five cellphones and gave Koyomi three of her contact numbers during the events of "Shinobu Time". Compared to Meme, who wants compensation, Kaiki, who works for money, and Yozuru, who works for free, Gaen demands "friendship" as a form of payment. In other words, she demands that people owes her a favour and doesn't pay her now, but later.
Magnesium hydroxide forms in the presence of water (MgO + H 2 O → Mg(OH) 2), but it can be reversed by heating it to remove moisture. Magnesium oxide was historically known as magnesia alba (literally, the white mineral from Magnesia ), to differentiate it from magnesia nigra , a black mineral containing what is now known as manganese .
The compound can be prepared by treating nickel or nickel(II) carbonate with acetic acid: . NiCO 3 + 2 CH 3 CO 2 H + 3 H 2 O → Ni(CH 3 CO 2) 2 ·4 H 2 O + CO 2. The mint-green tetrahydrate has been shown by X-ray crystallography to adopt an octahedral structure, the central nickel centre being coordinated by four water molecules and two acetate ligands. [5]
The missing 280 Nh and 281 Nh may be populated as daughters of 284 Mc and 285 Mc, producible in the 241 Am+ 48 Ca reaction, but this has not yet been attempted. [105] Of particular interest is 281 Nh, as it is the expected great-granddaughter of 293 119 , a possible product of the 243 Am+ 54 Cr reaction. [ 106 ]
