Answer:

The symbol for silver on the periodic table is Ag.

Explanation:

The elements are pure substances constituted by one single kind of atom.

Every element has a universal accepted chemical name and a symbol for simplicity of the chemical formulae and to enable scientific communication.

There are 118 known elements and all of them are represented in the periodic table.

The chemical symbol consists of one or two letters. The first letter is always upper case and the second one (if exists) is lower case.

The symbol Ag for silver derives from the latin name argentum.

The atomic number of silver (Ag) is 47 which permits you to find it easily in the periodic table where you can find this symbol and some important properties.

Describe how visible spectroscopy could be used to determine the order of a reaction in which a single colorless reactant produc

d1i1m1o1n [39]

Answer:

Explanation:

In a reaction, where, one of the reactant produces a colored product, visible spectroscopy can be used to determined the order of a reaction, the change in concentration of the reactant which forms the colored product is determined by absorbance measurement over time. The data for the concentration and time are plotted on the y and x axis and If we get a straight line it is a zero-order reaction. If instead, a plot of ln[concentration] versus time gives a straight line, it is a first order reaction. However, If 1/concentration versus time gives a straight line, it is a second order reaction kinetics. The other reactants may be changed while keeping this reactant as constant and change on rate of the reaction is observed to see If the other reactant affects the reaction or not.

A 15.6 grams of ethanol absorb 868 J as it is heated. The initial temperature is 21.5 degrees Celsius. What is the final tempera

77julia77 [94]

You have to use the equation q=mcΔT and solve for T(final).
T(final)=(q/mc)+T(initial)
q=the amount of energy absorbed or released (in this case 868J)
m=the mass of the sample (in this case 15.6g)
c= the specific heat capacity of the substance (in this case 2.41 J/g°C)
T(initial)=the initial temperature of the sample (in this case 21.5°C)

When you plug everything in, you should get 44.6°C.
Therefore the final temperature of ethanol is 44.6°C

I hope this helps. Let me know if anything is unclear.

A chemist heats a fixed amount of gas in a sealed glass container. Which law is the chemist most likely investigating?

PilotLPTM [1.2K]

The law which this chemist is most likely investigating heating a fixed amount of gas in a sealed glass container is: Gay Lussac’s law.

Gay Lussac's law states that when the volume of an ideal amount of gas is held (kept) constant, the pressure of the gas is directly proportional to the absolute (Kelvin) temperature of the gas.

Mathematically, Gay Lussac's law is calculated by using the formula;

$PT = K\\\\\frac{P_1}{T_1} = \frac{P_2}{T_2}$

Where:

$P_1$ is the original pressure.

$P_2$ is the final pressure.

$T_1$ is the original temperature.

$T_2$ is the final temperature.

In conclusion, the chemist is most likely investigating how changes in temperature affect the pressure of the gas by heating a fixed amount in a sealed glass container in accordance with Gay Lussac's law.
