There are two types of chemical compound one is covalent compound and another is ionic compound in chemistry. In ionic bonds, electrons are completely transferred. The correct option is option C.

<h3>What is chemical Compound?</h3>

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

During formation of a compound calcium act as cation as Ca²⁺ so, if any element has to react with this cation in a 1:1 ratio, must have -2 charge over it . Option C represents S⁻², which react with Ca²⁺.

Therefore, the correct option is option C.

The drawing shows two long rod shaped Structures with horizontal light dark bands
7nadin3 [17]

Answer:

From my side I think it is Photoreceptors cells :

A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes. To be more specific, photoreceptor proteins in the cell absorb photons, triggering a change in the cell's membrane potential.

There are currently three known types of photoreceptor cells in mammalian eyes: rods, cones, and photosensitive retinal ganglion cells. The two classic photoreceptor cells are rods and cones, each contributing information used by the visual system to form a representation of the visual world, sight. The rods are narrower than the cones and distributed differently across the retina, but the chemical process in each that supports phototransduction is similar. A third class of mammalian photoreceptor cell was discovered during the 1990s: the photosensitive ganglion cells. These cells do not contribute to sight directly, but are thought to support circadian rhythms and pupillary reflex.

How many moles are in 153’pp grams of KClO3
katen-ka-za [31]

Answer:

n = 1.24 moles

Explanation:

Given that,

Mass = 153 grams

Molar mass of KClO₃ = 122.55 g/mol

We need to find the number of moles.

We know that,

No. of moles = given mass/molar mass

So,

n=\dfrac{153}{122.55 }\\\\n=1.24

So, there are 1.24 moles in 153 g of KClO₃.
