Answer:
1040 g HCl
Explanation:
Al(OH)₃ + 3HCl => AlCl₃ + 3H₂O
moles Al(OH)₃ = 750g/78g·mol⁻¹ = 9.62 mol
moles HCl used = 3 x moles Al(OH)₃ consumed = 3(9.62)mol HCl = 1038.46 g. ≈ 1040 g HCl (3 sig.figs.)
Connective tissue is one of the four different types of tissues. It consists of cells suspended in a matrix, and consist of fibres running through it. It’s main job is to connect internal tissues. They also support and protect internal organs. Examples include cartilage, blood, lymph and adipose tissue.
Answer:
Wavelength D has the highest frequency
Hope that helps:)
During the time of Thompson and Dalton, no one studied their theories because the technology at the time didn't allow for further study in conducting their works. People were focused on other things. But it was revived and revised because of Neils Bohr and his atomic structure that led to more theories and eventually studies that continued on the works of Thompson and Dalton.
Hello!
The statement that a solution of sodium acetate (CH₃COONa) is weakly basic is true:
Sodium acetate is the conjugate base of Acetic Acid. When sodium acetate is dissolved in water, it follows the equation that is shown below:
CH₃COONa(s) → CH₃COO⁻(aq) + Na⁺(aq)
Now the Acetate (CH₃COO⁻) ion, has an equilibrium in water to produce hydroxyl (OH⁻) ions and (Acetic Acid CH₃COOH)
CH₃COO⁻ + H₂O ⇄ CH₃COOH + OH⁻
This is a weak equilibrium, and the hydroxyl ions cause the solution to be weakly basic.
Have a nice day!
