Answer:
Explanation:
The addition of AgNO3 to the system Cl⁻ react with result into the formation a precipitate of AgNO3, as such the reactant concentration decreases.
Suppose the concentration of a given substance is present in an equilibrium system is changed without a change in any of the other conditions, then, by le chatelier's principle, the position of equilibrium will move to decrease the concentration of the added substances. In order to relieve this constraint, the equilibrium will shift to the right favouring the forward reaction.
Based on the information provided in this image shown above, the measurement to two (2) significant figures is equal to 3.50 mm.
<h3>What is measurement?</h3>
Measurement can be defined as an act or process through which the size, magnitude, dimensions, or distance traveled by a physical object or body is taken, especially for the purpose of an experiment.
<h3>What is a scale of measurement?</h3>
A scale of measurement can be defined as a classification which is used to illustrate the attributes of the values that are assigned to variables associated with a data set.
<h3>What is a
significant figure?</h3>
In Mathematics, a significant figure can be defined as the number of digits in a numerical data (value), typically a measurement, which enhances its degree of accuracy.
Based on the information provided in this image shown above, the measurement of the film to two (2) significant figures is equal to 3.50 mm.

Atomic mass of Au = 196.9 g/mole
<span>it means that 1 mole of Au = 196.9 g </span>
<span>so 3.5 moles of Au = 196.9 X 3.5 = 689.15 g</span>
Answer:
C
Explanation:
energy from different sources leads to different types of rocks. energy inside the earth(volcanoes) melts rocks into liquid rock(molten larva) but energy from the sun(heat radiation) causes rock to weather(breakdown) into small pieces of rocks
Answer:
44.882
Explanation:
Li2S is made up of 2 Li and 1 S
Li's molar mass is 6.941 * (2) = 13.882
S's moalr mass is 32 * (1) = 32
add 12.882 + 32 = 44.882
