What will happen if a peeled banana is put on a hotplate?

Given the following balanced equation, determine the rate of reaction with respect to [SO2].

Gnoma [55]

Answer:

Rate = -1/2 Δ[SO2]/Δt

so its gonna be (in more simple terms) rate= -1/2Δ(SO2)/Δt

Question 3 of 5

rusak2 [61]

Answer:

A. More mass

C. Shorter distance between them

Explanation:

The two characteristics of a body experiencing greater gravitational force are that they have mass and a shorter distance between them.

This is conformity with Newton's law of universal gravitation.

The law states that "every object attracts one another with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them".

This law implies that the more the mass of two bodies, the more the gravitational force of attraction. And that the shorter the square of the distance between them, the more the attraction.

(a)-Use Lewis symbol store present there action that occurs between Ca and F atoms. (b)-What is the chemical formula of the most

Charra [1.4K]

Answer:

(a) The Lewis structure is shown in the image below.

(b) $CaF_2$

(c) Calcium loses 2 electrons to 2 atoms of fluorine and these 2 atoms of fluorine accepts each electron to form ionic bond.

(d) Calcium atom loses electrons.

Explanation:

Calcium is the element of second group and forth period. The electronic configuration of Calcium is - 2, 8, 8, 2 or $1s^22s^22p^63s^23p^64s^2$

There are 2 valence electrons of Calcium.

Fluorine is the element of group 17 and second period. The electronic configuration of the element fluorine is - 2, 7 or $1s^22s^22p^5$

There is 1 valence electron of fluorine.

The Lewis structure is drawn in such a way that the octet of each atom is complete.

Thus, calcium loses 2 electrons to 2 atoms of fluorine and these 2 atoms of fluorine accepts each electron to form ionic bond. This is done in order that the octet of the atoms are complete and they become stable.

Thus, the formula of calcium chloride is $CaF_2$ .

(a) The Lewis structure is shown in the image below.

(b) $CaF_2$

(c) Calcium loses 2 electrons to 2 atoms of fluorine and these 2 atoms of fluorine accepts each electron to form ionic bond.

(d) Calcium atom loses electrons.

Masteriza [31]

Answer:

Detail is given below.

Explanation:

Similarities:

All are the forms of matter.

Solid, liquid and gases are made up of ions, atoms and molecules.

They have shape and volume.

Molecules in Liquid and solid are closer to each others.

Liquid and gases can flow very easily.

Liquid and solid both can not compressed very easily.

Differences:

Molecule of gases randomly move everywhere and occupy all available space but liquid and solid's molecules are not move as much easier as molecules of gases can.

The density of gases are very low as compared to the liquid and solid.

Gas molecules are at long distance from each other while in liquid and solid they are closer to each other.

The very weak inter molecular forces are present between gas molecules as compared to the liquid and solids.

Solids have definite volume and shape but liquid and gases acquire the shape of container.

In solids molecules are tightly pack and very close to each other while in liquid molecules are not tightly pack like in case of solid.

The densities of solids are also very high as compared to the liquid and gas.

There are very strong inter molecular forces are present between solid molecules.
