Answer:

the agreement between a measured value and an accepted value

Explanation:

Accuracy measures how close a measured value is to a standard value. For example, if the weight of a bag of rice is 1 kg and the measured value is 0.90 kg rather than 0.75 kg, then the former measure value is more accurate than the later measured value.

Precision on the other hand is how close are the measured values to one another. For example, if that same 1 kg rice bag was measured 3 times and the readings were 0.75 kg, 0.73 kg and 0.74 kg then the measured values are precise but inaccurate.

Solution A is 0.44 M and reacts with 0.11 M of solution B. Assume that the value of x is 0, the value of y is 1, and r is 1.07 ×
xz_007 [3.2K]

Answer:

K, the rate constant = 9.73 × 10^(-1)/s

Explanation:

r = K × [A]^x × [B]^y

r = Rate = 1.07 × 10^(-1)/s

K = Rate constant

A and B = Concentration in mol/dm^-3

A = 0.44M

B = 0.11M

x = Order of reaction with respect to A = 0

y = Order of reaction with respect to B = 1

Solving, we get

r/([A]^x × [B]^y) = K

K = 1.07 × 10^(-1)/s/(0.44^0 × 0.11^1)= 0.9727

K = 0.9727

I guess you could call them that. In chemistry, we call them Metalloids though.
