(7) You boil water in an aluminum pan and cook the beans. After a few minute, you taste the beans and they taste like an aluminum can. The equation looks like this: beansFe + Al (s) ---> beansAl (aq) + Fe (s). (a) What type of reaction is this? Explain what you think happened. (b) This is also another type of reaction. What is it? Give another common example of this type of reaction. (c) Do you think it is OK to eat the green beans? Explain why or why not. * Your answer

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

Avariable that is not being directly tested during an experiment should be changed varied experimented controlled

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
