![]() ![]() It’s illegal in the UK to hold your phone for any purpose when driving, and that’s even if you’re stopped at traffic lights or queuing in traffic. Crucially, sat navs are less distracting – you won’t suddenly be tempted to glance at emails or notification bleeps from TikTok. Sat navs get constant power from a cable that plugs into the 12V socket (alongside a built-in battery), have menus that are clear to see and easy to navigate, and use preloaded maps that work without mobile signal. We love having GPS services in our pockets, but using these apps for long spells – such as a European road trip this summer – will be a serious drain on battery and mobile data, plus they’ll usually rely on an internet connection to be reliable. Smartphone navigation apps are free and preinstalled on most handsets these days, so does that mean physical sat navs are now redundant? Not so fast. All of the apps we’ve listed work with Android Auto and Apple CarPlay. Sygic is another popular option due to its high-quality 3D maps and its ability to let you download maps to use offline, ideal if you have poor internet or don’t want to eat your data, although you have to pay for an annual subscription to access all of its features. If you’re driving in congested areas, we recommend checking out Waze, an app that’s often the preferred choice of taxi and Uber drivers because it’s particularly good at helping you to find routes around traffic while showing camera warnings. Both give you live traffic updates and show information about travel times and closures. However, anyone with an iPhone should use Apple Maps instead.įunctionally it’s very similar to Google’s software, but has a slightly more simplified and uncluttered design that’s easier on the eyes. ![]() Our top pick is Google Maps, especially if you’re using an Android phone, because it’s speedy, reliable and has lots of visual and audio aids. ![]() There’s lots of smartphone apps you can download and use for free, but don’t forget that they drain your battery and use your mobile data if you're not on wifi. The bear went with his new master to Cuba but, unfortunately, could not get accustomed to the local tropic climate.You don’t always need a physical sat nav to guide you to your destination. “Fidel Castro with a bear cub Baikal that was given to him by Siberian geologists. Did you know that Fidel Castro actually owned a bear? A Jewish scientist used aqua regia to hide two solid gold Nobel Prize medallions from the Nazis. Since gold(III) chloride is soluble, the oxidized gold moves into solution, exposing more gold metal to be oxidized. The nitric acid oxidizes the gold to Au 3+, which then pairs with chloride ions from HCl. If you still want to use flash cards, check out the NAG SAG Quizlet.Īqua regia, a mixture of nitric and hydrochloric acids, can actually dissolve gold. No one knew where calcium chloride was at the hardware store. CaCl 2 contains three particles per mole and is very soluble, so it lowers water's melting point a lot.) (Melting/freezing point depression is directly proportional to the number of particles dissolved in a given volume of water. For example, ice melt (calcium chloride) works because it's highly soluble in water, its dissolution is exothermic, and it lowers water's melting point. Note that Castro Bear is still soluble when combined with Group 17 anions.Castro Bear (Ca 2+, Sr 2+, and Ba 2+ are insoluble when combined with the sulfate anion.).PMS (Pb 2+, Mercury(I) ion, and Silver ions are insoluble when combined with sulfate and group 17 anions.).SAG (Sulfates, Ammonium ion, and Group 17 halide ions).NAG (Nitrates, Acetates, Group 1 alkali metal ions). ![]()
