Answer:
antimatter is a material composed of so called antiparticles called positron has the same mass but a positive change
36.0 g of glucose divided by 180 g/mol = 0.200 moles of glucose
find molarity
0.200 moles of glucose / 2 liters = 0.100 molar solution

Explanation:
In liquids, the molecules are held by less strong intermolecular forces of attraction as compared to solids. Due to which they are able to slide past each other. Hence, they have medium kinetic energy.
In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.
So, when at 298 K and 1 atm 
exists in liquid state and 
exists as a gas then it means there occurs strong force of attraction between the molecules of due to which it exists in liquid form.
Thus, we can conclude that at 298 K and 1 atm, bromine is a liquid with a high vapor pressure, whereas chlorine is a gas. This provides evidence that, under these conditions, the forces among 
molecules are greater than those among 
molecules.
Electron Configuration is the distribution of electrons of an atom or molecule in an atomic or molecular orbitals.
So Na, or Sodium has 11 electrons, so the number should add up to 11
Na: 1s² 2s² 3p⁶ 3s¹

Start by balancing elements that don’t appear in single form. So, for number 4
Start by adding 2 to Cu2O to balance the oxygen
2Cu2O + C —-> Cu + CO2
Now the oxygen is balanced, but the Cu is not. This can now simply be mitigated by adding 2 to the single Cu
2Cu2O + C —-> 2Cu + CO2
That’s your final answer for #4
