Answer 2
Distance traveled over a period of time is?
Answer: Average speed is the total distance traveled divided by the elapsed time. (Average speed is not the magnitude of the average velocity.) Speed is a scalar quantity; it has no direction associated with it.
Facts about traveling: Travel is the movement of people between distant geographical locations. Travel can be done by foot, bicycle, automobile, train, boat, bus, airplane, ship or other means, with or without luggage, and can be one way or round trip.

predict the product 1-bromo propane is treated with sodium metal

Answers

When 1-bromo propane is reacted with sodium metal, the propane and sodium bromide are formed.

Propane and sodium bromide are produced when the 1-bromo propane is reacted with sodium metal. The Bromine which is present in the 2-bromopropane is removed through hydrogenation and combines with the sodium metal which results in the production of propane and sodium bromide.So we can conclude that propane and sodium bromide are produced when the 1-bromo propane is reacted with sodium metal.

Answers

Problem 57EDraw the Lewis structure for CO with an arrow representing the dipole moment. UseFigure 9.10 to estimate the percent ionic character of the CO bond. Step by step solutionStep 1 of 2Lewis structure of CO:Carbon has four valence electrons and oxygen has six valence electrons. If only one bond wereto be formed between carbon and oxygen atoms, carbon would have five electrons and oxygenwould have seven electrons.The single bond between these two atoms is not sufficient to lead to an octet on each atom . Tocomplete the octet of each atom in CO, we must employ a triple bond .A triple bond is formed bythe six electrons sharing between these two atoms and it is shown as follows.\nThe Lewis structure of CO with an arrow representing the dipole moment.The arrow towards anoxygen atom it represents is a highly electronegative atom.

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.

What is Lewis dot structure?

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.

A 12.17 g sample of a compound contains 7.77 g of iron, Fe, 1.44 g of phosphorus, P, and oxygen, O. Calculate the empirical formula for the compound.

Answers

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

The reaction below shows how silver chloride can be synthesized. AgNO3 NaCl Right arrow. NaNO3 AgCl How many moles of silver chloride are produced from 15. 0 mol of silver nitrate? 1. 0 mol 15. 0 mol 30. 0 mol 45. 0 mol.

Answers

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.
