1. mol ratio of Al(NO₃)₃ : Na₂CO₃ = 2 : 3

2. Na₂CO₃ as a limiting reactant

Given

Reaction

2 Al(NO₃)₃ + 3 Na₂CO₃ → Al₂(CO₃)₃ + 6 NaNO₃

Required

mol ratio

Limiting reactant

Solution

The reaction coefficient in the chemical equation shows the mole ratio of the components of the compound involved in the reaction (reactants and products)

1. From the equation mol ratio of Al(NO₃)₃ : Na₂CO₃ = 2 : 3

2. mol : coefficient of Al(NO₃)₃ : Na₂CO₃ = 2 mole/2 : 2 mole/3 = 1 : 0.67

Na₂CO₃ as a limiting reactant (smaller)

Answer: C

Explanation:

According to the passage, as a result of a mutation, an organism may evolve for better survival. The correct option is C.

The mutation is a condition in which genes and DNA sequence changes. Mutation occurs due to mutagens. These mutagens can be biological or chemical. Cells come in contact with these mutagens and undergo mutation.

The mutation causes diseases, due to changes in DNA sequence and genes. People die due to mutation. Sometimes mutation causes the birth of new genes and traits in an organism.

So, in the given condition, the organism will evolve new traits that can be good or necessary for the better survival of the organism. The passage is talking about radiation.

Therefore, the correct option is С, which may evolve for better survival.

The question is incomplete. Your most probably complete question is given below:

When a cell divides to grow into two new cells, the double helix splits into two single strands of chromosomes, each of which can then replicate a mirror image of itself. This process, called mitosis, happens every time a cell divides, except for sex cells preparing for sexual reproduction. The result is two new cells, each with a double helix of DNA strands identical to that of the original cell.

Though rare, sometimes an error occurs in this process, resulting in a mutation. Radiation or the appearance of other chemicals can increase their frequency. Sometimes an extra base is inserted, substituted, deleted, or damaged. Usually, these mistakes repair themselves, but sometimes they remain and, as a result, can create a change in the coding for a specific trait. If the new trait helps the organism survive, it may be duplicated and passed on to offspring, which, in time, may lead to an evolution in the organism.

Given parameters:

Mass of the car  = 2550kg

Initial velocity  = 0m/s

Solution:

First problem is to find the force exerted on the car;

  Velocity  = 4.5m/s

   Time  = 0.2s

Acceleration  = [tex]\frac{final velocity - initial velocity }{time}[/tex]   = [tex]\frac{4.5 - 0}{0.2}[/tex]  = 22.5m/s²  

Force  = mass x acceleration  = 2550 x 22.5  = 57375N

B. Force on the car with crumple zones

Acceleration  = [tex]\frac{final velocity - initial velocity }{time}[/tex]    = [tex]\frac{4.5 - 0}{0.3}[/tex]   = 15m/s²

 Force  = 2550 x 15  = 38250N

a. The force when the car is rigid and accelerated is 57375N.

b. The force where the car should have  crumple zones should be 38250N

Since Mass of the car  = 2550kg

Initial velocity  = 0m/s

Here,

Velocity  = 4.5m/s

Time  = 0.2s

a.

Here force = mass * acceleration

= 2550 * (4.5 - 0/0.2)

= 2550 * 22.5

= 57375 N

b.

Here force is

= mass * acceleration

= 2550 * (4.5 - 0/0.3)

= 2550 * 15

= 38250 N

Explanation:

Na     +     Cl    =      NaCl

23 g        35.5 g  

23 g sodium reacts with 35.5 g of chlorine

29 g of sodium reacts with 35.5 x 29 / 23 g of chlorine

= 44.76 g

So 44.76 g of chlorine reacts and 49 - 44.76 = 4.24 g of chlorine is left over .

All the sodium is used up in the reaction .

Answer:

5.88583×10¹⁰ ft/min

Explanation:

From the question given above, the following data were obtained:

Speed of light (in m/s) = 2.99×10⁸ m/s

Speed of light (in ft/min) =.?

Next, we shall convert 2.99×10⁸ m/s to ft/s. This can be obtained as follow:

0.3048 m/s = 1 ft/s

Therefore,

2.99×10⁸ m/s = 2.99×10⁸ m/s × 1 ft/s / 0.3048 m/s

2.99×10⁸ m/s = 980971129 ft/s

Finally, we shall convert 980971129 ft/s to ft/min. This can be obtained as follow:

1 ft/s = 60 ft/min

Therefore,

980971129 ft/s = 980971129 ft/s × 60 ft/min / 1 ft/s

980971129 ft/s = 5.88583×10¹⁰ ft/min

Thus, 2.99×10⁸ m/s is equivalent to 5.88583×10¹⁰ ft/min

Solution

Explanation:

A solution is a well-mixed mixture containing a solvent and dissolved solute.

It is termed a homogenous mixture.

Solutions are homogeneous mixtures of solutes and solvents. In a solution, the solute particles are distributed uniformly in the solvent. The solute is the substance that is dissolved to make the solution

It is usually present in smaller amount than the solvent. The solvent is the dispersing substance that allows the solute to go into solution.

The solute could be a solid or liquid or gas but usually a liquid. A solution in which the solvent is water is an aqueous solution.

D "Before the process, the substance was a liquid. After the process, it was a gas.

Explanation:

hope this helps.

According to the forces of attraction , before the process substance was liquid and after the process it was a gas as gas molecules are farther away than those in liquid.

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.

Obviously liquid water comes from the sink, ice can be found in the freezer, and water vapor comes from boiling water, it is always in the air around us.

Liquid water is used for hydration or for food preparation. Ice is used to cool things down or in drinks, and water vapor isn't really used by humans. Rather, it serves as a natural greenhouse gas.

A column on the periodic table is known as a group or family. The group is a vertical arrangement of elements  on the periodic table.

Elements in the same group have the same number of valence electrons after their group number.

For example, all the elements in group 1 have one valence electron. Those in group 2 have 2 valence electrons.

The valence electrons of an atom determines its chemical properties. So, all elements in the same group have the same chemical properties.

By moving the thickness slide just a little bit to the right and just before the oceanic crust turns to continental crust, I can use either the temperature slider or the composition slider by moving either of them to the right until the oceanic crust turns to be continental crust.

Explanation:

By moving the thickness slider slightly to the right and just before the oceanic crust transitions to continental crust, one can use either the temperature slider or the composition slider to the right until the oceanic crust transitions to continental crust.

Continental crust, the outermost layer of Earth's lithosphere that forms the planet's continents and continental shelves and is formed near plate boundaries between continental and oceanic tectonic plates.

Almost all of Earth's land surface is made up of continental crust.

The thinner oceanic crust is typically less than four miles thick, whereas the thicker continental crust can be up to 25 miles thick.

Individuals can choose to use the temperature slider or the composition slider to the right through till oceanic crust transitions to continental crust by moving the thickness slider bit to the right and just prior to the oceanic crust transitions to continental crust.

Thus, these are the three ways one can change oceanic crust into continental crust using the sliders.
