How many significant figures are in the measurement, 0.005890 g?

pantera1 [17]

4 significant figures. Use a rule called the Atlantic-Pacific rule where if the period is absent (Atlantic), you would start counting the numbers from right to left. If the period is present (Pacific), then start counting the numbers from left to right. Since the period is present, start from 5 and there are 4 digits including 5.

How do the properties of a compound like h2o or nacl illustrate the concept of emergent properties?

Softa [21]

Answer and explanation;

Na - metal

Cl - poisonous gas

NaCl - cyrstaline solid that is edible

An emergent property is a property which a collection or complex system has, but which the individual members do not.

Water emergent properties: cohesion & adhesion, versatile solvent, temperature moderation, freezing.

The properties of a compound can be very different from the properties of the elements that make them, for example, Sodium is an explosive metal, and Chlorine is a toxic gas, however, sodium chloride is a Delicious table salt!

The pressure on 2.50 L of gas is changed from 4.5 atm to 2.2 atm. What is the new volume of gas?

swat32

Answer:

Explanation:

The new volume can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we are finding the new volume

$V_2 = \frac{P_1V_1}{P_2} \\$

From the question we have

$V_2 = \frac{2.5 \times 4.5}{2.2} = \frac{11.25}{2.2} \\ = 5.1136666...$

We have the final answer as

Hope this helps you

Question 6

kompoz [17]

Considering the combined law equation, the new temperature is -244.56 °C or 28.44 K.

<h3>Boyle's law</h3>

Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant: if the pressure increases, the volume decreases while if the pressure decreases, the volume increases.

Mathematically, this law states that the multiplication of pressure by volume is constant:

P×V=k

<h3>Charles's law</h3>

Charles's law states that the volume is directly proportional to the temperature of the gas: if the temperature increases, the volume of the gas increases while if the temperature of the gas decreases, the volume decreases.

Mathematically, Charles' law states that the ratio of volume to temperature is constant:

$\frac{V}{T} =k$

<h3>Gay-Lussac's law </h3>

Gay-Lussac's law states that the pressure of a gas is directly proportional to its temperature: increasing the temperature will increase the pressure, while decreasing the temperature will decrease the pressure.

Mathematically, Gay-Lussac's law states that the ratio of pressure to temperature is constant:

$\frac{P}{T} =k$
