Answer:
( c ) sunlight.
Explanation:
the leaves are closer to the sunlight they require.
That's a ionic compound because it has a metal and polyatomic parts within the chemical formula.
You have to find the stoichiometric ratio between AlCl₃ and BaCl₂. The common element between them is Cl. So, the ratio of Cl in BaCl₂ to AlCl₃ is 2/3. The molar mass of AlCl₃ is 133.34 g/mol. The solution is as follows:
Mass of AlCl₃ = (6 mol BaCl₂)(2 mol Cl/1 mol BaCl₂)(1 mol AlCl₃/3 mol Cl)(133.34 g/mol) = 533.36 g AlCl₃
A conductor allows heat, light, sound, or an electric charge to run through it.
Answer:
Density rectangular block = 7.47 (Approx) gm/cm³
Explanation:
Given:
Length = 8.335 cm
Width = 1.02 cm
Height = 0.982 cm
Mass = 62.3538 gm
Find:
Density rectangular block
Computation:
Volume of block = lbh
Volume of block = (8.335)(1.02)(0.982)
Volume of block = 8.3486 cm³
Density = Mass / Volume
Density rectangular block = 62.3538 / 8.3486
Density rectangular block = 7.47 (Approx) gm/cm³
