An integral membrane protein is a type of membrane protein that is permanently attached to the biological membrane.
Answer:
2.28 g of CsF.
Explanation:
The following data were obtained from the question:
Molar mass of CsF = 151.9 g/mol.
Volume = 300 mL
Molarity of CsF = 0.05 M
Mass of CsF =.?
Next, we shall convert 300 mL to litre (L). This can be obtained as follow:
1000 mL = 1 L
Therefore,
300 mL = 300 mL /1000 mL × 1 L
300 mL = 0.3 L
Therefore, 300 mL is equivalent to 0.3 L
Next, we shall determine the number of mole CsF in the solution. This can be obtained as follow:
Volume = 0.3 L
Molarity of CsF = 0.05 M
Mole of CsF =.?
Molarity = mole /Volume
0.05 = mole of CsF /0.3
Cross multiply
Mole of CsF = 0.05 × 0.3
Mole of CsF = 0.015 mole.
Finally, we shall determine the mass of CsF needed to prepare the solution as follow:
Mole of CsF = 0.015 mole.
Molar mass of CsF = 151.9 g/mol.
Mass of CsF =.?
Mole = mass /Molar mass
0.015 = mass of CsF /151.9
Cross multiply
Mass of CsF = 0.015 × 151.9
Mass of CsF = 2.28 g
Therefore, 2.28 g of CsF is needed to prepare the solution.
Answer:
Chemical properties would be like what you would make food with because you are changing the structure of the ingredients.
Physical properties would be like a chair or the device you asked this question on.
Explanation:
Atoms will combine with each in order to become more chemically stable by sharing electron and Compounds are formed between two atoms that have chemical bond that links them together.
In order for molecules and crystals to form, atoms or ions must maintain a long-lasting attraction to one another. Ionic and covalent bonds are formed by the sharing of electrons, while ionic bonds are formed by the electrostatic attraction between two oppositely charged ions. There are "strong bonds" or "primary bonds" like covalent, ionic, and metallic bonds as well as "weak bonds" or "secondary bonds" like dipole-dipole interactions, the London dispersion force, and hydrogen bonding. The strength of chemical bonds varies greatly. By sharing or transferring electrons between the involved atoms, strong chemical bonds are created.
Since opposing electric charges attract, the positively charged protons inside a nucleus and the negatively charged electrons that surround it are drawn to one another. Placing an electron between them
