Plz help! :) :D I will mark you as BRAINLIEST!!!
nadezda [96]

Answer:

Some of the physical and chemical properties of magnesium are:

-The term ‘magnesium’ is derived from the Greek word magnesia, which refers to the name of the place from where it was extracted.

-Magnesium is closely related to manganese and magnetite.

-About 2.1% of the Earth’s crust contains magnesium. This makes magnesium the 6th most found element.

-The biggest deposits of magnesium is found in the seawater. It has been calculated by scientists that a cubic mile of seawater contains about 6 million tons of this element

2nd answer:

Physical Properties of Magnesium: ”I’m a highly stable element, so you can count on me”

Chemical Properties of Magnesium: ”I love to travel but I do corrode aluminum so we won’t be flying off on adventures in airplanes planes anytime soon

If someone takes a material that looks pure, and then they do something to it that results
Sati [7]

Answer:

The determination of the nature of the combination of the two separate materials in the original material that looks pure is based on the characteristic of the change process they undergo to become two separate materials.

Therefore, they can know if they initially had a mixture or a compound by the following steps;

1) If the two separated materials can be easily remixed to form the original material, then they likely have a mixture of the two separate materials

2) If the process that results in the formation of the two separate materials, involves the absorption or evolves heat or other forms of energy, then the original substance was a compound

3) If the two newly formed materials is seen to be a permanent change, then the original material was a compound

What volume is occupied by 0.102 molmol of helium gas at a pressure of 0.95 atmatm and a temperature of 305 kk ?
zalisa [80]

The volume occupied by 0.102 mole of the helium gas is 2.69 L

<h3>Data obtained from the question</h3>

The following data were obtained from the question:

  • Number of mole (n) = 0.102 moles
  • Pressure (P) = 0.95 atm
  • Temperature (T) = 305 K
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Volume (V) =?

<h3>How to determine the volume </h3>

The volume of the gas can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

Divide both sides by P

V = nRT / P

V = (0.102 × 0.0821 × 305) / 0.95

V = 2.69 L

Thus, the volume of the gas is 2.69 L
