You have a container which has the capacity to hold 3 L water. If it already has 2.25 L water in it, how much more water in mL can you still add to fill it completely?

Answers

Answer:

750mL

Explanation:

According to this question, a container which has the capacity to hold 3 L water already has 2.25 L water in it. This means that the container needs (3 - 2.25) = 0.75L to get filled up completely.

However, this question needs the volume of water needed to fill the container in milliliter (mL). To do this, we say;

1L = 1000mL

0.75L = 0.75 × 1000

= 750mL

Therefore, 750mL of water can still be added to fill up the container completely.

Which change in this process would shift the equilibrium to produce the
maximum possible NH3?
3H2 + N2 2 2NH3 + energy
A. Removing the N2 as it forms
B. Removing the NH3 as it forms
c. Decreasing the pressure
D. Increasing the temperature

Answers

Answer: B I think, I'll put my reasoning below.

Explanation:

It's not A because removing N2 would only shift the equation the opposite way.

It's not C and D because I don't think those affect the specific amount of each reactant/product produced. I think temperature only affects the speed at which the reaction is performed, which won't affect anything in this case.

Removing the ammonia as it forms is the correct answer to produce the maximum possible NH₃.

What is Haber's Process ?

It is an industrial process for manufacturing ammonia by reaction of nitrogen with hydrogen.

N₂+3H₂ ⇌ 2NH₃

The reaction is reversible and exothermic

To answer this question we will consider all the options and answer

Option D ) Increasing Temperature

Haber's process requires an optimal temperature of 450°C ,on Increasing temperature the yield of ammonia gets slow down.

Option C) Decreasing Pressure

Haber's Process requires high pressure to drive the reaction , higher the pressure more is the yield.

Option A ) Removing the N₂ as it forms , on removing  N₂ the reaction will drive on the reverse side hence low yield of NH₃ .

Option B) Removing the NH₃ as it forms , this can actually increase the yield as removing the ammonia will lead to shift the equilibrium and therefore increasing the yield.

Therefore Option B ,  Removing the ammonia (NH₃) as it forms is the correct answer to produce the maximum possible NH₃.

Explanation:

The molecular ion has 24 valence electrons and The SN of N in the central of the structure is = 3 according to VSEPR Theory. and  this depicts trigonal planar geometry about the central nitrogen also this corresponds to sp^2 hybridization of the valence orbital of the atom N.

The 6 valence electrons are shared between N and O's, while the 2p orbital of Nitrogen will combine with the 2p orbital on each oxygen atoms in order to form four (4) π molecular orbitals. the binding orbital is occupied by a pair of electrons. Four electrons are bounded by eight electrons

Cells are organized to form tissues is the statement best summarizes how part of the human body is ordered. Hence option 1 is correct.

What are cells?

Cells are defined as the smallest component of living things, including biological tissues, that is capable of independent existence. The cell membrane, nucleus, and cytoplasm are the three major structural components of a cell. A cell's membrane, which encloses it and regulates what enters and leaves it, controls the flow of chemicals.

Organs are formed from tissues, which are composed of cells. Organ systems, such as the skeletal and muscular systems, are groups of organs. Cells, tissues, organs, and organ systems make up the several levels of organization in the human body. The human body, which is made up of countless billions of cells, is a marvel of structure and functionality.

Thus, cells are organized to form tissues is the statement best summarizes how part of the human body is ordered. Hence option 1 is correct.

Explanation:

Step 1: Given data

Mass of the balloon (m): 400 kgKinetic energy of the balloon (KE): 3200 J

Step 2: Calculate the velocity (v) of the balloon

The kinetic energy is the energy that the balloon has due to its movement. We can calculate the velocity of the balloon using the following expression.

v = √(2 × KE/m)

v = √(2 × 3200 J/400 kg) = 4 m/s

How is the bent geometry related to the tetrahedral geometry?

Answers

Answer:

this shape is called bent or angular. a molecule with four electron groups around the central atom orients the four groups in the direction of a tetrahedron.if there are four atoms attached to these electron groups then the molecular shape is also tetrahedral.

Explanation:

Hope this helped Mark BRAINLEST!!!!!

Bent geometry related to the tetrahedral geometry because of;

The two lone pairs and the two bonds

Bent Geometry in chemistry simply means that a molecule forms a V-shape with two other lone pairs and 2 bonds in a non collinear arrangement.

Example is water (H₂O). In this example Oxygen will form a V-shape with the 2 hydrogen molecules which are the lone pairs as well as two bonds for each of the hydrogen molecule.

Tetrahedral geometry is one in which there is a central atom surrounded by 4 isolated atoms that are bonded with the central atom to form a tetrahedral shape. A very good example is Methane(CH₄). In CH₄, Carbon will be the central atom and the four corner atoms bonding with Carbon will be the hydrogen atoms.

        In conclusion, the relationship between bent geometry and tetrahedral geometry is that they both have 2 bonds and 2 lone pairs.

Tungsten and molybdenum both have the BCC crystal structure, and Mo forms a substitutional solid solution for all concentrations at room temperature. Compute the unit cell edge length for a 84 wt% W - 16 wt% Mo alloy. The room-temperature density and atomic weight of W are 19.3 g/cm3 and 183.85 g/mol, the room-temperature density and atomic weight of Mo are 10.22 g/cm3 and 95.94 g/mol, respectively.

Answers

Answer:

the unit cell edge length is 3.1585 × 10⁻⁸ cm

Explanation:

Given the data in the question;    

density = 100 / [ (84/19.3) + (16/10.22) = 100 / 5.917889 = 16.8979 g/cm³

so Aug density p_aug = 16.8979 g/cm³

Aug Atomic weight = 100 / [ (84/183.85 ) + (16/95.94) = 100 / 0.623665

= 160.3424 g/mol

now

volume = ( no. of atoms in BCC × Aug Atomic weight) / ( Aug density × Avogadro's number)

we substitute

volume = ( 2 × 160.3424 ) / ( 16.8979 × 6.023 × 10²³ )

volume =  320.6848 / 1.017760517 × 10²⁵

volume = 3.15088 × 10⁻²³ cm³

Now, unit cell edge length will be;

= [tex]Volume^{1/3}[/tex]

= [tex](3.15088 * 10^{-23})^{1/3}[/tex]

= 3.1585 ×  10⁻⁸ cm  

Therefore, the unit cell edge length is 3.1585 × 10⁻⁸ cm

Answers

Answer:

This is a stoichometric ratio

Explanation:The equation is already balanced, so all you have to do is.

1. Count the molar mass of Ammonia N nitrogen atom has an atomic mass of 14 so add 14+ 3 hydrogens which each have a mass of 1 that gives you 17 grams per mole of ammonia on the right side, so they want to know how much hydrogen is needed to make 100 grams of ammonia, so what you have to do is divide 100/17=2.94 that is your ratio so you now know there is 2.94 times everything in the equation so at first you had 3 moles of hydrogen now you have 3*2.94 moles of hydrogen. You also have 2.94 moles of N2 gas. It's just a ratio if you plug in 200 instead you have to multiply everything by 200/17=11.76 ratio.

1st step count molar mass of product.

2nd plug number they gave you and divide it by molar mass ratio then multiply everything in equation by that ratio.
