An advertisement for a new fish food claims that lab studies show that fish grew three inches in three weeks while eating the fo
od. Travis wondered if the food was worth the extra cost? To evaluate the claim in the advertisement, Travis should A)look at the data for the control group to see how much the fish grew without the new food.
B)check the lab results to see if the researchers changed the dependent variable in the same way.
C)examine the data to find how the researchers changed the variables within the control group.
D)determine if the results show the independent variable changing as the dependent variable was changed.
Electrons in atoms occupy energy levels, also called electron shells, outside the nucleus . Different shells can hold different maximum numbers of electrons. The electrons in an atom occupy the lowest available energy level first. This is the shell nearest the nucleus.
there are 7. 505 x 1022 atoms in 3.5 grams of silicon.
Explanation:
So, 1 mole of silicon will have a mass of 28.0855 g and the number of atoms will be 6.022 x 1023. Therefore, there are 7. 505 x 1022 atoms in 3.5 grams of silicon.
To form bonds with noble gases, a lot of energy is required to form those bonds. Halogens, on the other hand, are extremely reactive. ... The halogens tend to be very reactive, while the noble gases are in no way reactive and don't bond easily, if at all.
