A tape diagram is a rectangular visual model resembling a piece of tape, that is used to assist with the calculation of ratios and addition, subtraction, and commonly multiplication. It is also known as a divided bar model, fraction strip, length model or strip diagram.
Taking the (reasonable) assumption that all active chlorine present in a liquid bleach is in the form of hypochlorite ions, 1% active chlorine is equivalent to 0.141 mol/kg ClO − (0.141 mol/L if we assume density=1). For a solid bleach, 100% active chlorine is equivalent to 14.1 mol/kg ClO −: lithium hypochlorite has a molar mass of 58.39 g ...
A variant of the story has been told with 11 camels, to be divided into 1 ⁄ 2, 1 ⁄ 4, and 1 ⁄ 6. [22] [23] Another variant of the puzzle appears in the book The Man Who Counted, a mathematical puzzle book originally published in Portuguese by Júlio César de Mello e Souza in 1938. This version starts with 35 camels, to be divided in the ...
For example, the label of a household bleach product may specify "5% sodium hypochlorite by weight." That would mean that 1 kilogram of the product contains 0.05 × 1000 g = 50 g of NaClO. A typical oxidation reaction is the conversion of iodide I − to elemental iodine I 2. The relevant reactions are NaClO + 2 H + + 2 I − → NaCl + H 2 O ...
Tetraacetylethylenediamine, commonly abbreviated as TAED, is an organic compound with the formula (CH 3 C(O)) 2 NCH 2 CH 2 N(C(O)CH 3) 2. It is a white solid commonly used as a bleach activator in laundry detergents and in the production of paper pulp. TAED is synthesized through the acetylation of ethylenediamine.
The simplest organic chloramine is N-chloromethylamine, CH3NHCl; [7] notable examples include N-chloromorpholine (ClN(CH 2 CH 2) 2 O), N-chloropiperidine, and N-chloroquinuclidinium chloride. [8] Chloramines are commonly produced by the action of sodium hypochlorite on secondary amines: R 2 NH + NaOCl → R 2 NCl + NaOH
Bleach: Thousand-Year Blood War spoilers follow. Ichigo and co are facing their biggest threat yet after 366 episodes, four movies, and two parts of the revival series Bleach: Thousand-Year Blood War.
The Child Behavior Checklist (CBCL) is a widely used caregiver report form identifying problem behavior in children. [1] [2] It is widely used in both research and clinical practice with youths. It has been translated into more than 90 languages, [3] and normative data are available integrating information from multiple societies. Because a ...
