The activity series of metals as well as the electrode potential of metals can be used to compare the reactivity of metals.

<h3>What is used in comparing reactivity of metals?</h3>

The reactivity of metals can be compared using their electrode potentials which is a measures of the ability of the metal to donate electrons to another metal.

When comparing the reactivity of metals, the metal with the lesser negative electrode potential will be more reactive than another with a greater negative or positive electrode potential.

Therefore, the activity series of metals as well as the electrode potential of metals can be used to compare the reactivity of metals.

identify the postulate of Dalton's theory that is violated by the following observations: 59.95% of one sample of titanium dioxi

Inga [223]

<u>Answer:</u> This violates the law of constant composition.

<u>Explanation:</u>

Dalton's theory is based on mainly two laws, which are law of conservation of mass and law of constant composition.

Law of constant composition states that a compound always contain the elements in the fixed ratio by their masses.

For Example: In water $(H_2O)$ , the hydrogen and oxygen are present in the fixed ratio of 1 : 9 by their mass.

We are given:

A sample of titanium dioxide having 59.95 % of titanium and another sample of titanium dioxide having 60.10 % of titanium.

As, the compound is titanium dioxide. So, the mass percent of titanium must remain the same in both the elements.

Hence, this violates the law of constant composition.

A student determines the volume of a cube to be 4.6 cm?

pav-90 [236]

Answer:

6.98%

Explanation:

% error= |experimental value - actual value|/actual value × 100

Experimental value= 4.6 cm

Actual value= 4.3 cm

% error = |4.6-4.3|/4.3 × 100

% error = 6.98%

How many liters of 4M solution can be made using 100 grams of lithium bromide

uysha [10]

Molar mass of LiBr (mm )= 86.845 g/mol

Molarity ( M ) = 4 M

Mass of solute ( m ) = 100 g

Volume ( V ) = in liters ?

V = m / mm * M

V = 100 / 86.845 * 4

V = 100 / 347.38

V = 0.2875 L

hope this helps!.
