Answer: Non covalent interactions.
Explanation: The non covalent interactions can be defined as the interaction among molecules based on the variation among the electromagnetic radiations.
These molecules are not attached to each other based on the sharing of the electrons.
These interactions are Van der Waals, electrostatic, hydrophobic interactions.
The interaction among the molecules is important in order to maintain the three dimensional structure of compound such as carbohydrates and protein molecules.
A common conversion factor is that 22.4 liters of a gas at STP is equal to one mole of that substance.
21 L / 22.4 L = 0.9375 moles of CO2
One mole of any substance contains an Avogadro’s number of atoms: 6.022 x 10^23 atoms/mol.
0.9375 mol x (6.022 x 10^23 atoms/mol) = 5.646 x 10^23 atoms of CO2
21 liters of CO2 contains 5.646 x 10^23 atoms of CO2.
Answer:about 2 grams of methane
Explanation:
idk just got this right
Mass of medicinal agent taken = 1.2 g
the volume is 60 mL
Specific gravity = 1.20
So the mass of solution = specific gravity X volume = 1.20 * 60 = 72g
Now if we have increased the volume by 0.2 so the new volume = 60.2
New mass = 72 + 1.2 = 73.2
Specific gravity = mass / volume = 73.2 / 60.2 = 1.22 g/mL
Explanation:
1. Under the influence of heat, wood produces easily substances that react eagerly with oxygen, leading to the high propensity of wood to ignite and burn.
2. Water is a natural conductor of electricity and if you throw water on an electrical fire, you can get shocked or electrocuted. Also, water may enable to fire to spread by conducting electricity throughout the room and potentially igniting flammable materials.
