Review, Hasbro My3D

The Hasbro My3D turns your iPhone into a View-Master for 3D viewing, but suffers from toy-like build quality and fleeting novelty from only a handful of apps.

The Hasbro My3D is a cute idea – and that’s about as far as it gets. The toy offers the retro appeal of a View-Master by turning your iPhone or iPod into a 3D viewer, and comes with a collection of apps to experiment with. While young users will likely be amazed by it, the wonder is sure to wear off. That said, it’s an inexpensive option for distracting kids no longer placated by two-dimensional entertainment options.

Review, Samsung Infuse 4G

The Samsung Infuse 4G sets records for screen size and thinness, but some other specs fall short of its supersized reputation.

You can accuse Samsung of a lot of things, but it knows how to keep up with trends. The electronics maker just took the wraps off the Infuse 4G on May 5, and as of May 15, it’s officially available on AT&T. This isn’t just another Android phone, though. At 4.5 inches diagonally, the Infuse has a larger screen than almost any phone on the market and Samsung also claims it is thinner than the iPhone 4, making it the leanest phone in the United States. Couple that with 1080p video recording and the ability to install apps outside of the Android Market and we’ve got ourselves a hot ticket. But do the details match the headlines?

iBuyPower’s flagship Erebus Gaming PC delivers the bang if you’ve got the bucks. Ridiculous gaming performance outshines some minor design oddities.

FAKTOR-FAKTOR YANG MEMPENGARUHI LAJU REAKSI

1. Konsentrasi
Larutan dengan konsentrasi yang besar (pekat) mengandung partikel yang lebih rapat, jika dibandingkan dengan larutan encer. Semakin tinggi konsentrasi berarti semakin banyak molekul-molekul dalam setiap satuan luas ruangan, akibatnya tumbukan antar molekul makin sering terjadi dan reaksi berlangsung semakin cepat.
