What is the difference between physics and chemistry laboratory (4)

Chemistry

Answer:A fundamental difference is that physics is more focused to finding the universal laws of general processes, whereas chemistry focuses more on details and specific phenomena, such as what is the boiling point of this substance and why.

Explanation: hope it help

There is a lot more physics in a chem lab than there is in a physics lab. Physical properties are also looked at in chem lab experiments, but they aren't the only things that are looked at. To give you an example, it has a melting point and boiling point. It also has a denseness, color, odor, and transparency The electron, a particle that is so important to the study of chemistry, is a physical thing. Its mass, charge, and energy are all physical things. Voltmeters, ammeters, magnetic spinners, mass-spectroscopes, Geiger counters, and cloud chambers are just some of the physics instruments that are important in a chemistry lab. The list is long. In any chemistry lab, there is a centrifuge. It's a great tool that uses four physics principles to do its job. Pipettes and burettes are high-quality instruments that were made with thermal expansion constants in mind. This word is often used to talk about the barometer: There aren't any barometers in this lab, but do you think it can still be good?

It's now time to write down all of the chemistry principles that are found in the tools, properties, and applications of a physics lab. I'll start it for you now.

In order to build voltaic cells, you need iron filings and electrolytes.
Radioactive decay, alpha, beta, and gamma emission, and atomic transformation all happen.

When 40 grams of ammonium nitrate explode 14 grams of nitrogen and 8 grams of oxygen form. How many grams of water form
DerKrebs [107]

Answer:

18 grams of water

Explanation:

The Balance Chemical Reaction is as follow,

                     2 NH₄NO₃    →    2 N₂  +  O₂  +  4 H₂O

According to Equation,

                     160 g (2 moles) NH₄NO₃ produces  =  72 g (4 moles) of H₂O

So,

                     40 g of NH₄NO₃ will produce  =  X g of H₂O

Solving for X,

                     X =  (40 g × 72 g) ÷ 160 g

                     X  =  18 g of H₂O

How many mole ratios can be written for a chemical reaction involving 3 substances
Anika [276]
There can be three mole ratios that can be written involving three substances.It depends on the constant of your reactant to your product. It also depends on the asked mole ratio. But the maximum would be 3 mole ratios because you have 3 substances in your reaction.

A sample of hydrogen was collected by water displacement at 23.0°C and an atmospheric pressure of 735 mmHg. Its volume is 568 mL
ziro4ka [17]

Answer:

V = 552 mL or 0.552 L

Explanation:

First, we need to calculate the number of moles of H2 using the ideal gas equation which is:

PV = nRT

Solving for n:

n = PV / RT

Where:

P = Pressure

V = Volume

R = Gas constant (0.082 L atm / K mol)

T = Temperature in K

Let's convert first both pressure in atm, remember that 1 atm = 760 mmHg

P = 735 / 760 = 0.967 atm

Pwater = 21 / 760 = 0.028 atm

Finally temperature to Kelvin:

T = 23 + 273.15 = 296.15 K

Now, at first the hydrogen was collected by water displacement so pressure is:

P = 0.967 - 0.028 = 0.939 atm

Now the moles of hydrogen:

n = 0.939 * 0.568 / 0.082 * 296.15

n = 0.022 moles

Now that we have the moles, let's calculate the volume when the pressure is 735 mmHg

V = nRT/P

V = 0.022 * 0.082 * 296.15 / 0.967

V = 0.552 L or 552 mL

This is the volume that hydrogen occupies.
