hydrogen and helium and the most abundant elements in a nebula.
Answer:
Conduct more trials
Explanation:
Theoretical Probability can be defined as what someone is expecting to happen
Experimental Probability on the other hand, is defined as what actually happens.
Probability is usually calculated in the same way for experimental probability and that of theoretical probability. You divide the total number of possible ways in which a particular outcome can happen, by the total number of outcomes itself.
In Experimental probability, the more times a probability is tried, it gets closer and even more closer to theoretical probability.
So, for the question, Jamie should improve the number of tries more, so as to get his experimental probability results to be closer to the theoretical probability result.
The answer is false. Because Daltons theory stated that the Atom was a solid ball.
Answer:
Air is called a homogeneous mixture because all of the elements that make up air (oxygen, nitrogen, argon, carbon dioxide etc.) are not able to be distinguished between when you look at air.
Explanation:
A heterogeneous mixture would be something like trail mix. You can look at the bowl of trail mix and pick out the raisins from the nuts from the chocolate. A homogeneous mixture is something where the individual elements can't be picked out by the plain eye. When you look at air you can't say oh that part is oxygen and that is argon when you are going on a walk. Air is a solution and thus you can't pick out each part.
