- Q: What ingredients are added to the bread
- A leavening agent is an additive that can form a bulky and porous structure in the process of bread processing, and has a soft, palatable property, also known as a bulking agent.

- Q: i just bought a bottle of lucas transmission fix for my k5 blazer. when i add this to the fluid do i have to take some transmission fluid out, or just pour the bottle in.
- Almost all additives like that are make believe. That being said, there is enough slop room in a transmission to take it without being overfilled. If you are having transmission problems, a fluid change would be a good place to start.
- Q: i thought the many name brands had additives for the winter months, but my concern is really with the no brand discount service stations
- Technically, dry gas is either a cheap alcohol. like methanol or has ether additives. NEVER use it in your car. ALL gasolines get additives to prevent fuel line freeze. Fuel lie freeze is TYLICALLY started because of the presence of WATER in the fueel, not the gas. Gas does NOT freeze until WAY below zero!!! Use a good FUEL INJECTOR cleaner additive like GUMOUT once in a while, and NEVER use that anti-freeze junk. It can RUIN your fuel pump and fuel lines and cause REAL trouble on down the line!!!
- Q: What is the additive identity property?
- it might be mis-firing. no one will really know till you get it checked. and anytime your check engine light comes on, it's because of a sensor that set it off also, you can take it to autozone or advanced auto parts to have it checked for free.
- Q: why should additives not be added to food?
- Well - that is bit of a vague question - what do you consider an additive? Salt, is an additive when used to preserve food and keep it from spoiling. Lemon juice is an additive when added to cut apples to keep them from browning. There are hundreds of additives that are added to various foods that keep them from spoiling and keep us from getting sick from food-borne-illness. Even more additives to make the food tasty, colorful and delicious. There are some additives that are controversial. But a lot of the studies that people quote were tests on animals using a huge amount of the additive, much much more than what a human would consume. So should additives not be used? Of course not, we are better off with food that doesn't spoil and doesn't make us sick.
- Q: For example, -(7.8)? and why?
- It's very simple -- the additive inverse is the same number with the opposite sign. The opposite of - 7.8 (negative 7.8) is + 7.8 (positive 7.8). The opposite of + 7.8 is - 7.8. The additive inverse (opposite) of - 3,962.424 is + 3,962.424. The additive inverse (opposite) of + 3/4 is - 3/4. Just switch the sign from + to - or from - to +. It's called additive inverse because if you add a number to its additive inverse, you will always get 0. Don't confuse additive inverse with inverse. The inverse of 3/4 is 4/3. When you MULTIPLY a number by its inverse you will always get 1. Hope that helps!
