Why it is important always to use the same balance during the course of an experiment in chemistry lab?

As balances can be offset to slightly different amounts, giving a slim error margin even when well set. This error margin is made less influential by using the same balance for every mass determination, therefore keeping the two errors relevant to one another. For example if one balance is +0.001g and another is -0.001g, a mass taken from one of each shows a 0.002g difference even though they were meant to be the same mass. If both are 0.001g then they are both 0.001g over, however the difference between them is now zero. This becomes more important when weighing reactants and then weighing resulting products for a yield determination calculation.

∙ 14y agoA balance scale measures mass because it does so by balancing a known mass against the unknown mass.
A spring scale does not do this and would measure the unknown to be a different weight if used on the moon while the balance would give the same result as on Earth.

∙ 10y agoweighing balance is used to measure the weight. thought by knowing weight, you can find mass..
weight = mass x gravitational pull
gravitational pull is taken as 10 for simplicity..

So it a sure everything’s included by balancing both side

What is a reference solution in a chemistry lab?
The reference solution in a chemistry lab is the solution that is always present in the experiment, and it doesn't go away while you are testing other solutions. It is kind of like a base camp for your experiment; you're always starting off or going to include it.
Do I need a chemistry degree to become a scientist?
It certainly helps, but not necessarily. You could always become a mad scientist.
What is the conclusion on specific heat capacity of liquid experiment?
The theory of the heat transfer experiment is the transfer of thermal energy between molecules, due to a temperature gradient. The conclusion of the experiment is that thermal conductivity is much higher in metals and does not change within thickness.
What would it be called if a lithium atom had 2 electrons?
the answer in a chemistry test is always A!
What is a fixed proportion in chemistry?
You think probable to the law of definite proportions: the ratio of elements in a compound is always the same. Now this law is for the most part obsolete.
Why is it important always to use the same balance during the course of an experiment?
Different balances might display different results. Therefore, using the same balance will keep your results accurate.

Positive energy balance important when?
Positive energy balance is always important. Having your energy in balance keeps you from slipping too far into the negative and keeps you on a path toward happiness.

Why is the mediants role important in a scale?
It always helps balance the tonic and the leading note.
What is the most important thing in science?
The most important thing in science is that you must always listen to instruction and folio the rule
What is it important to use the same amount of water each time you conducted the experiment?
It is important to use the same amount of water each time you conduct the experiment because if you change more than 1 thing in an experiment, then you can't know the true result because you tested too many things. You need all controlled variables in an experiment except for 1 manipulated variable.

Why did organic chemistry become important?
everything is made of organic compounds, from tip of your sandals to your hat. the computer in which you see this answer is made of plastic and some kind of polymer. what is it? everything is organic chemistry. your breakfast to supper. you see organic chemistry everywhere. so we need more to produce, so it is always important, but we have realized only now.!!!
Why the trial balance always be in balance?
Trial balance is always balance because of every entry in double entry system is in balance as related to debit account and credit account.
