For a reaction with a rate law: rate = k[A]2[B], doubling the concerntration of A and tripling the concerntration of B will cause the rate to
An organic sample (3 grams mass) is taken from an archeological site. The sample has a beta emission rate of 4.3 counts per minute. These decays originate predominantly from carbon-14 with a half-life of 8270 years. If the abundance of carbon-14 i..
