where r, the constant of proportionality, is negative. To emphasize the fact that A is decreasing, this equation is often written A0 = −kA or dA dt = −kA, k >0 constant. This is the form we shall use. The constant of proportionality k is called the decay constant. Note that this equation is both linear and separable and so we can use either ... Feb 02, 2009 · The "porportionality constant" is a bit of an achedemic exercise rather than real chemistry, but homework is homework, I suppose. 0.265 grams is 265 milligrams. If 265 milligrams was neutralized by 10 ml, then the porportion would be 256 mg/10 ml = 25.6 mg/ml. The rest of the facts presented are not relevant, which is typically achedemic!
Constant of proportionality Nila uses the equation c=8h to figure out the total amount c she should charge a customer if she babysits for h hours. Find the constant of proportionality and explain what it means.
