Nickel nitrate is the inorganic compound Ni(NO 3) 2 or any hydrate thereof. In the hexahydrate, the nitrate anions are not bonded to nickel. Other hydrates have also been reported: Ni(NO 3) 2. 9H 2 O, Ni(NO 3) 2. 4H 2 O, and Ni(NO 3) 2. 2H 2 O. [3] It is prepared by the reaction of nickel oxide with nitric acid: NiO + 2 HNO 3 + 5 H 2 O → Ni ...
The aqueous complex Ni(NO 2) 2 (H 2 O) 4 forms when an alkali metal nitrite is added to a nickel salt solution: Ni(H 2 O) 2+ 6 + 2 NO − 2 ⇌ Ni(NO 2) 2 (H 2 O) 4 + 2 H 2 O; K = 0.16 at standard conditions. The complex is a much more intense emerald green colour than the Ni(H 2 O) 6 2+ ion. Brooker claims that intense light photocatalyses the ...
In a solid nitrogen matrix, nickel atoms combine with nitrogen molecules to yield Ni(N 2) 4. [1] Nickel phosphide Ni 2 P has density 7.33 and melts at 1100 °C. [4] The mineral Nickelskutterudite has formula NiAs 2-3, nickeline has formula NiAs and breithauptite has formula NiSb. NiAs melts at 967° and has density 7.77. NiSb melts at 1174°.
Bis(2,4-pentanedionato)nickel(II) is prepared by treating nickel nitrate with acetylacetone in the presence of base. The product is the blue-green diaquo complex Ni(CH 3 COCHCOCH 3) 2 (H 2 O) 2. [9] Ni(NO 3) 2 + 2 CH 3 COCH 2 COCH 3 + 2 H 2 O + 2 NaOH → Ni(CH 3 COCHCOCH 3) 2 (H 2 O) 2 + 2 NaNO 3
In its Q1 FY 2025 (ending Sept. 30) results, EPS rose a mere 10%, yet the stock trades at 31 times forward earnings. Apple 's best quarter since 2022 began saw 16% EPS growth, yet it trades for 30 ...
The S&P 500 isn't cheap right now. Its price-to-earnings (P/E) ratio of 24.7 is around 36% higher than its long-term average of 18.1 going back to the 1950s. Growth stocks are responsible for most ...
Data by YCharts. However, a look ahead suggests the stock is even cheaper. Wall Street is forecasting earnings per share of $4.02 for the coming fiscal year, which kicks off in late January.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
