To convert grams to atoms, we first need to find the moles and then multiply by Avogadro's constant.
0.1310 g * (1 mol/22.99 g) * (6.022*10^23 atom/1 mol) = 3.431 *10^21 atoms.
If these are you choices:
(1) Both the solid and the liquid are good conductors.
(2) Both the solid and the liquid are poor conductors.
(3) The solid is a good conductor, and the liquid is a poor conductor.
(4) The solid is a poor conductor, and the liquid is a good conductor.
Then the answer is number 4. This is because ionic compound conducts electricity when it is dissolved in water.
The correct answer would be the first option. Material A having a smaller latent heat of fusion would mean that it will take only less energy to phase change into the liquid phase. Latent of heat of fusion is the amount of energy needed of a substance to phase change from solid to liquid or liquid to solid.
Answer:
Her oxygen would be traveling throughout her body and carbon dioxide will be released every time she breathes out. The oxygen will come in through the respiratory system which is a body system that helps you breathe with lungs, which then delivers the oxygen molecules to other organs and body systems. Oxygen will go through the circulatory system and circle around until the some oxygen goes in the cells or the stored glucose. Then some Oxygen molecules go into the cells and make energy with Glucose. She would have higher glucose/ healthy sugar to be considered healthy. But if she was healthy she would have glucose in her digestive system( where the food goes when you swallow it some of the parts are the stomach and intestines both small and large) which will be transferred to the circulatory system then it will circle around the system

Answer:
0.07906687 amu
Explanation:
For Boron ₅B¹¹, the number of protons is 5 and the mass is 11. The mass is the number of protons plus the number of neutrons, so:
neutrons = 11 - 5 = 6
The mass of an atom is concentrated in the nucleus, so it is the mass of the protons + the mass of the neutrons. The mass of 1 proton is 1.00727647 amu/proton, and the mass of 1 neutron: 1.00866492 amu/neutron, so for the element given the theoretical mass (mt) is:
mt = 5* 1.00727647 amu/proton + 6*1.00866492 amu/neutron
mt = 11.08837187 amu
The mass defect (md) is the theorical mass less the real mass:
md = 11.08837187 - 11.009305
md = 0.07906687 amu
