Answer:

15 mol

Explanation:

the balanced equation is AgNO3 + NaCl > NaNO3 + AgCl.

the stequiometry of the reactions says: one mol of silver nitrate reacts with one one mol of silver chloride to produce one mol of silver nitrate and one mol of sodium chloride.

by proportions, if you have 15 mol of AgNO3 you're gonna have 15 mol of AgCl

From 15 mol of Silver nitrate, the moles of silver chloride produced have been 15 mol. Thus, option B is correct.

The balanced chemical reaction for the synthesis of silver chloride has been:

[tex]\rm AgNO_3\;+\;NaCl\;\rightarrow\;AgCl\;+\;NaNO_3[/tex]

From the balanced equation, since there has presence equal moles of silver nitrate and sodium chloride, the moles of silver chloride formed has been equivalent. Thus, 1 mole of silver nitrate gives 1 mole of silver chloride.

The moles of silver nitrate available are,  [tex]\rm M_A_g_N_O_3=15\;mol[/tex]

The moles of silver nitrate produced can be given as:

[tex]\rm 1\;mol\;AgNO_3=1\;mol\;AgCl\\15\;mol\;AgNO_3=15\;\times\;1\;mol\;AgCl\\15\;mol\;AgNO_3=15\;mol\;AgCl[/tex]

Thus, the moles of silver chloride produced have been 15 mol. Thus, option B is correct.

Answer:

A) antigens present on the invaders

Explanation:

Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens. The immune system recognizes and destroys, or tries to destroy, substances that contain antigens

Answer:

Fe₃PO₄

Explanation:

They have given the total mass of the compound, the mass of iron and the mass of phosphorus. So we can find the mass of oxygen.

Mass of oxygen = 12.17 - (7.77 + 1.44) = 2.96g

So we can now find the empirical formula.

Element - mass - Mr - Mass÷Mr - Ratio - Simplest Ratio

Fe - 7.77g - 55.8 - [7.77÷55.8] - [0.14÷0.05]  - 2.8 = 3

P   - 1.44g -   31   -   [1.44÷31]    - [0.05÷0.05] - 1

O  - 2.96g -   16  -   [2.96÷16]   - [0.19÷0.05]  - 3.8 = 4

[The simplest ratio was obtained by dividing the answer of mass÷mr with the smallest value. Phosphorus had the smallest value of mass÷mr=0.05, so all other answer were divided by 0.05]

Emperical formula = Fe₃PO₄

Answer:

its D, convection cells

Explanation:

At the upper left is the atomic number, or number of protons. In the middle is the letter symbol for the element (e.g., H). Below is the relative atomic mass, as calculated for the isotopes found naturally on Earth. At the very bottom is the name of the element (e.g., hydrogen).

Answer:

D............................

There are two types of chemical compound one is covalent compound and another is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. The correct representation is option D.

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

Covalent bond is present in molecule HCl. Hydrogen has 1 electron in its outermost shell. Chlorine has 7 electrons in its valence shell. So one one electron from each element is shared between them to form a covalent bond.

Therefore, the correct representation of arrangement of electrons in a hydrogen chloride molecule is option D.

Explanation:

The first question, " which is the best career " isn't answered by science since it's subjective. different individuals will have different views, but I believe, whatever field a particular person like is the best field career. The third question is a " computer and technology " related question along with It being subjective while the forth

the question, just like the up to two questions, it's also subjective but the second question is in fact understandable by science.

Answer:

Explanation:

Divide kPa by 101.325 as that is 1 atmospheric.

Hope that helps

Answer:

One atmosphere is equal to 101.33 kilopascal

So to change 45.6 kPa to atm, you would divide it by 101.33 kPa

[tex]\frac{45.6}{101.33} = 0.45 \ atm[/tex]

The formation of molecule can easily be shown by drawing Lewis dot structure. Since atom's Lewis dot structure has three dots. Therefore, in below given ways, we can have Lewis dot structure of CO.

Lewis dot structure is a way to represent the valence electron of an element in the form of dot. These are mainly beneficial in understanding the chemical formula of covalent compound.

Carbon contains four valence electrons, whereas oxygen has six. Carbon has five electrons but oxygen has seven electrons if just one link is established among carbon and oxygen atoms.

The solitary connection formed in between two atoms is insufficient to form an octet on every atom. A triple bond is required to finish the octet of the each atom in CO. The six electrons shared by these two atoms create a triple bond. The dipole moment arrow will point between carbon to oxygen.

Therefore,  in above given ways, we can have Lewis dot structure of CO.

The plasma membrane is a structure that has several distinct roles in the cell

The plasma membrane is mainly composed of the phospholipid Bilayer, which is a layer of two sheets located in the internal and external parts. The Phospholipids are said to be Amphipathic because they have both properties of Hydrophobic and hydrophilic

*The Carbohydrate Molecules attach to the Plasma Membrane such as to the lipids and Proteins:

when They attach to the Proteins, they are known as glycoproteins, and they help in cell recognition, when they attach to the lipids, they are known as Glycolipids

*Protein Molecules play an important role in transport system such as Carrier Proteins
