A sample of an unknown element contains 20 atoms with a mass of 10.0129 amu and 80 atoms with a mass of 11.0093 amu. calculate the average atomic weight of the element. What is the element?

the sunflower because each experiment got the same results

hope this !

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

the answer is c. it will give up it's valence electron to the other atom.

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
