The concentration inside the cell is greater than outside describes a cell after diffusion. Therefore, the correct option is option A among all the given options.

Diffusion is regarded a passive mode of cellular transport in biology since it does not require additional energy to occur. It is the primary mode of transport for vital chemicals (such as amino acids) between cells. It is necessary for the production of energy via respiration and photosynthesis.

Some chemicals, referred to as "simple diffusion," are not controlled by the cell's own proteins. membrane. It is found in substances with low molecular weight, such as water, gasses and fat-soluble compounds. The concentration inside the cell is greater than outside  describes a cell after diffusion.

A clear explanation of misconception of sugar is energy and energy is sugar is below.

Sugars are the disaccharide carbohydrate, it means they are formed by the combination of two monosaccharides.

One of the component of the sugar is glucose and we know that glucose is the source of energy in our body. So, sugars are naturally present in many food substance which in turn breaks down in the glucose and their composite constituent and releases energy. But we can never compare sugar as the main source of energy or equivalent to energy.

Hence, Energy means sugar is the misconception.

Explanation:

Particle;

              ³⁴₁₆S²⁻

The number of particles we seek is the protons, neutrons and electrons.

    ³⁴₁₆S²⁻ is an ion that has gained two electrons from its stable state.

34 is the mass number  = number of protons + neutrons

16 is the atomic number  = number of protons

Number of protons  = 16;

 Number of neutrons  = mass number - atomic number

                                     = 34 - 16

                                     = 18

Number of electrons; In a neutral atom, the number of protons and electrons are the same.

 This atom has gained two more electrons

Answer:

Half life = 1.83 sec

Explanation:

Given data:

Total amount of Ar-35 = 1.80 g

Amount left after 5.49 sec = 0.225 g

Half life of Ar-35 = ?

Solution:

At time zero = 1.80 g

At first half life = 1.80 g/2 = 0.9 g

At 2nd half life = 0.9 g/2 = 0.45 g

At 3rd half life = 0.45 g/2 = 0.225 g

Half life:

Half life = Time elapsed / number of half lives

Half life = 5.49 sec / 3

Half life = 1.83 sec

Answer:

C. transition elements

Explanation:

Transition elements are groups of metallic elements that have partially filled d orbitals. They occupy the d-block of the periodic table (Group 3-12). Examples of elements that fall under this category are Nickel (Ni), Cobalt (Co), Copper (Cu), Zinc (Zn) etc. Transition metals have outstanding properties that distinguishes them from other elements.

One of these properties is their ability to form colored compounds due to their unfilled d electron shells. They form ions that are usually colored in solid compounds and in solution.

The elements that have been colored in the solid and solution have been transition elements.Thus, option C is correct.

The periodic table has been consisted of metals, non-metals, and metalloids. The presence of valence electrons of the elements has been responsible for the chemical properties of the elements.

The transition elements have been the metals that have been consisted of electrons in the d orbitals. The presence of electrons results in the atom to excited to higher energy and have radiations in the visible region.

Thus, the aqueous and solid transition elements have been colored. Thus, option C is correct.

Answer:

The potential energy of the two vehicles increased because they were moved against the magnatic forces. The potential energy of the pink car increased more then the potential energy of the purple car because the pink car was closer to the center magnet.

Explanation: I had this same exact question on a quiz and this was my response and I got a 100%

The effects of the movement of the cars closer to the center of the magnet are ;

A) The potential energy of the Two vehicles will be increased

B) The potential energy of one car ( pink car) will change more than purple car due to the distance between the pink car and the center magnet.

Potential energy is the energy contained in a body at rest, The increase in potential energy occur when an object continues to be at rest ( i.e. opposes movement ).

When the cars are moved closer to the center magnet the cars will oppose the motion because their movement is against the magnetic forces that exist between the center magnet and the cars ( i.e. like pole repel while unlike poles attract ).  so as Lucia moves the cars closer their potential energies will continually increase ( i.e. the closer the car the higher its potential energy ).

Therefore the pink car been closer to the center magnet will experience a higher change in its potential energy than the purple car.

Hence we can conclude that The effects of the movement of the cars closer to the center of the magnet are ;  The potential energy of the Two vehicles will be increased, The potential energy of one car ( pink car) will change more than purple car due to the distance between the pink car and the center magnet.

Lewis structures have a central atom and a terminal atom

The central atom is an atom that is bound to 2 or more other atoms, while a terminal atom is bound to 1 other atom

In describing Lewis's structure the steps that can be taken are:

1. Count the number of valence electrons from atoms in a molecule

2. Give each bond with a pair of electrons

3. The remaining electrons are given to the terminal atom so that an octet is reached

4. The remaining electrons that still exist in the central atom

5. If the central atom is not yet octet, free electrons are drawn to the central atom to form double bonds

Nitrogen -N : valence electron : 5 , need 3 electron for stable⇒central atom

Chlorine-Cl : valence electron : 7, need 1 electron for stable⇒terminal atom

So that N will bind 3 Cl atoms to get stability (using electrons together with covalent bonds), so that there is 1 lone pair in N atoms and 3 lone pairs from each Cl atom (a total of 10 lone pairs of electrons)

Answer:

There are 14.2 moles of carbon in 170.3 grams of carbon

Explanation:

The mass of one mole of carbon is known as the molar mass of carbon. the unit of molar mass is grams/mole, g/mol.

The molar mass of carbon is 12 grams. This means that for every 12 grams of carbon, one has one mole of carbon.

To determine the number of moles of carbon present in 170.3 grams of carbon, the given mass of carbon, that is 170.3 grams is divided by 12.

The formula to use is: number of moles = mass of substance/molar mass of substance

Number of moles of carbon = 170.3 g / 12 g/mol = 14.2 moles

Therefore, there are 14.2 moles of carbon in 170.3 grams of carbon
