A solution that appears dark orange in color is not absorbing all orange wavelengths of light.
I can tell you there certainly is enough information, so we can eliminate the fourth option right away.
Group two elements tend to form 2+ cations, and nitrogen forms 3- anions. To make a stable substance, we need those to cancel out. Calling the group 2 element X:
N2X3 would cause the charge to be 2(-3) + 3(2) = 0
This would mean 3 ions of X and 2 anions of N would be a stable ionic compound.
The correct answer is measurement in Ci/Bq, the amount of radioactive materials released into the environment, and <span>number of disintegrations of radioactive atoms in a radioactive material over a period of time. I hope this helps.</span>
The correction answer is Alloy. If you look at the graph, and pay attention to the wording in the question, it says "using low force to move the ball." The best option for moving the ball with low force is Alloy. Hope this helps!
The unit used to measure the volume of a solid is cubic centimeters.
