On the same date, the 13-inch M2 MacBook Air received a price cut from $1199 to $1099. [22] On March 4, 2024, Apple announced a refreshed M3 MacBook Air in both 13-inch and 15-inch sizes. This model retains the same design as the M2 MacBook Air, but adds support for two external displays when the lid is closed.
Apple M1 is a series of ARM-based system-on-a-chip (SoC) designed by Apple Inc., launched 2020 to 2022.It is part of the Apple silicon series, as a central processing unit (CPU) and graphics processing unit (GPU) for its Mac desktops and notebooks, and the iPad Pro and iPad Air tablets. [4]
MacBook Pro (13-inch, M1, 2020) On November 10, 2020, Apple introduced a 13-inch MacBook Pro with two Thunderbolt ports based on the Apple M1 system on a chip, launched alongside an updated MacBook Air and Mac Mini as the first Macs with Apple's new line of custom ARM-based Apple silicon chips. [3]
Sodium hydrosulfide is the chemical compound with the formula NaSH. This compound is the product of the half-neutralization of hydrogen sulfide (H 2 S) with sodium hydroxide (NaOH).
2 NaOH(aq) + H 2 SO 4 (aq) → Na 2 SO 4 (aq) + 2 H 2 O(l) ΔH = -112.5 kJ (highly exothermic) In the laboratory it can also be synthesized from the reaction between sodium bicarbonate and magnesium sulfate, by precipitating magnesium carbonate. 2 NaHCO 3 + MgSO 4 → Na 2 SO 4 + MgCO 3 + CO 2 + H 2 O
The M3 Pro has a 192-bit memory bus where the M1 and M2 Pro had a 256-bit bus, resulting in only 150 GB/sec bandwidth versus 200 GB/sec for its predecessors. The 14-core M3 Max only enables 24 out of the 32 controllers, therefore it has 300 GB/sec vs. the 400 GB/sec for all models of the M1 and M2 Max, while the 16-core M3 Max has the same 400 ...
SO 2 + NaOH → NaHSO 3 SO 2 + NaHCO 3 → NaHSO 3 + CO 2. Attempts to crystallize the product yield sodium metabisulfite (also called sodium disulfite), Na 2 S 2 O 5. [6] Upon dissolution of the metabisulfite in water, bisulfite is regenerated: Na 2 S 2 O 5 + H 2 O → 2 Na + + 2 HSO 3 −. Sodium bisulfite is formed during the Wellman-Lord ...
Soda lime canister used in anaesthetic machines to act as a carbon dioxide scrubber. Soda lime, a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO), is used in granular form within recirculating breathing environments like general anesthesia and its breathing circuit, submarines, rebreathers, and hyperbaric chambers and underwater habitats.
