Answer: 89.7 L

Explanation:

89.6 volume, in liters, does 128 grams of O2 occupy at STP. Therefore, option A is correct.

A volume is simply the amount of space taken up by any three-dimensional solid. A cube, a cuboid, a cone, a cylinder, or a sphere are examples of solids. Volumes differ depending on the shape.

Every three-dimensional object requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an object within the boundaries of three-dimensional space. It is also known as the object's capacity.

1 mole Oxygen has mass 32 grams

Mole of Oxygen in 128 g mass = 128 g / 32 g/mol

= 4.0 mol O2

At Standard temperature and pressure this has volume

= 4.0 mol × 22.4 L/mol

= 89.6 L

Thus, 89.6 volume, in liters, does 128 grams of O2 occupy at STP, option A is correct.

the answer is d.

1. Write the symbols for each element.

2. Find the charge for each element using the Periodic Table. Write it above each element. (because there is a (III) after nickel, the charge of nickel is +3. oxygen is in group 16, which means it has a -2 charge.)

3. See if the charges are balanced (if they are you're done!)

- when you criss cross (getting Ni2O3, the charges are canceled out, so the equation is balanced.

Answer:

[tex]\boxed {\boxed {\sf About \ 2.96 \ moles \ of \ Argon}}[/tex]

Explanation:

To convert from grams to moles we must use the molar mass, which is found on the Periodic Table.

Use the molar mass as a ratio.

[tex]\frac{39.9 \ g \ Ar}{1 \ mol \ Ar}[/tex]

Multiply by the given number of grams: 118

[tex]118 \ g \ Ar *\frac{39.9 \ g \ Ar}{1 \ mol \ Ar}[/tex]

Flip the fraction so the grams of argon will cancel each other out.

[tex]118 \ g\ Ar * \frac{1 \ mol \ Ar}{39.9 \ g \ Ar}[/tex]

[tex]118 * \frac{ 1 \ mol \ Ar}{39.9 \ g \ Ar}[/tex]

[tex]\frac {118 \ mol \ Ar }{ 39.9 }[/tex]

[tex]2.95739348 \ mol \ Ar[/tex]

The original measurement of grams had 3 significant figures, so our answer must have 3 sig figs.

For the number we calculated, that is the hundredth place. The 7 in the thousandth place tells us to round the 5 to a 6.

[tex]2.96 \ mol \ Ar[/tex]

There are about 2.96 moles of Argon in 118 grams.

The increase in global temperature melts the ice in polar regions. This worsely affects the animals living there. Hence, they will migrate to other areas but this is in fact not possible for their adaptation in other areas and they may subject to extinction.

Global warming is the rise of temperature of earth surface all over the world. The significant reason for global warming is green house effect. Gases like carbon dioxide, methane gas etc. are intensely absorbing temperature that is radiating back from earth.

Hence, these gases are increasing the atmospheric temperature in earth. Global warming have very serious impacts that going up to the major discussion to solve nowadays.

The melting of polar icebergs and rising of sea level definitely leads to the extinction of animals living in polar region. They cant be adopted to other regions and migrating to other areas does not save them. Hence, they will extinct from earth. Therefore, option d is correct.

Explanation:

if your car is on 7000 ml it has issues and you need to take it to a mechanic.

Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter, causing the metal to stiffen and fracture. This is known as metal fatige. The bending causes that to occur.

A metal is a substance that has a shiny look when freshly processed, polished, or shattered, and conducts electricity and heat rather effectively. Generally speaking, metals are malleable and ductile.

These characteristics are the outcome of the metallic link that exists between the metal's atoms or molecules.

The earth's crust is where most pure metals are found. They are discovered in ores, which are solid materials from which metals and minerals may be extracted. The majority of the planet's iron mass, which makes up over a third of its mass, is located in its core.

Thus, Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter.
