How many mL of a stock solution of 2.00 M KNO3 are needed to prepare 100.0 mL of 0.15M KNO3? with work plz

Answers

Using the law of dilution :

Mi x Vi = Mf x Vf

2.00 x Vi = 0.15 x 100.0

2.00 x Vi = 15

Vi = 15 / 2.00

Vi = 7.5 mL

hope this helps!

In the electron cloud model, electrons are said to be moving so fast that a person can _____.

Answers

Answer: Not determine their exact position.

Explanation: In the electron cloud model, electrons are said to be moving so fast that a person cannot determine their exact position.

This phenomenon goes well off with the Heisnberg Uncertainity Principle (HUP)which states that the momentum (Δm) and position (Δx) of an obejct cannot be determined simultaneously at the same time.

The mathematical relation of HUP is -

Δx Δm ≥ h/ 4π

where h = Planck's Constant

cannot describe their exact position.

Two pieces of metal with exactly the same mass are placed on a surface in bright sunlight. The temperature of the 1st block increases by 3°C while the temperature of the 2nd increases by 8°C. If the specific heat of the 2nd block is 0.24 J/g-K, what is the specific heat of the 1st block?

Answers

Answer:

0.64 J/g-K

Explanation:

Solving this question relies on the relization that both blocks receive the same amount of energy but of course their temperature cannot rise by the same amount even if you had the same mass of both because they have different specific heat capacities.

amount of energy received by block 1 = amount of energy received by block 2

specific heat of block 1 * ΔT of block 1 = specific of block 2 * ΔT of block 2

C * 3 = 0.24 * 8

C = 0.64 J/g-K

Arrange the following measurements, in seconds, from the greatest bias to the least bias. 6.63 ± 0.01 s, 6.6 ± 0.1 s, 6.52 ± 0.05 s, 6.4 ± 0.5 s

Answers

I understand here "bias" to be the uncertainty of measurements. So the order will be the following:

6.4 ± 0.5 s
6.6 ± 0.1 s,
6.63 ± 0.01 s,
6.52 ± 0.05 s,

(notice how the second number, the one behind the symbol ± gets smaller, as the bias gets smaller).

Name two elements that have properties similar to copper

Answers

Nickel and iron . Tin and zinc. Gold and silver. They all have properties similar to copper

Final answer:

Silver and gold are two elements which have properties similar to copper. These common properties include sheen, malleability, ductility, and their ability to conduct heat and electricity, attributable to their similar atomic structures.

Explanation:

Two elements that have properties similar to copper, which is a metal, include silver (Ag) and gold (Au). All these elements fit into the same category - metals, that demonstrate certain characteristics:

They appear shiny, and have the ability to be formed into different shapes (malleable) and drawn into wires (ductile).
They act as good conductors of heat and electricity.

These properties stem from their similar atomic structures, placed in the same group on the periodic table.
