Why does when an unknown sample of a metal is placed in a flame a bright green light is released?
A green flame is due probable to copper.
What unknown metal displaces aluminum from solution but does not displace sodium Using the activity series determine the unknown metal?
magnesium
What is the unknown metal in the AP Chemistry Heat Effects and Calorimetry Lab?
that is supposed to be unknown until you figure it out.
How do scientists determine metal composition?
Scientists determine metal composition using techniques such as spectroscopy, x-ray fluorescence, and mass spectrometry. These methods analyze the elemental makeup of a sample by measuring the emission or absorption of energy when it interacts with the metal atoms. By comparing these signals to known standards, scientists can identify and quantify the metals present in a sample.
Why must a metal sample always be dry before its mass or volume is taken?
A wet metal sample can have water molecules attached to its surface, which can affect its mass and volume measurements. Removing water ensures accurate data and prevents errors in calculations.
What metal has a mass of 35.4 and a volume of 3.11?
A sample of an unknown metal has a mass of 35.4g and a volume of 3.11cm^3. The metal is Lead.
Why does when an unknown sample of a metal is placed in a flame a bright green light is released?
A green flame is due probable to copper.
What can you predict about an element from its position in the periodic?
You can see if its a metalliod or a metal or a non-metal.
Which metal is contained in a thermometre?
usually mercury
What unknown metal displaces aluminum from solution but does not displace sodium Using the activity series determine the unknown metal?
magnesium
When a forensic scientist would use a flame test?
A forensic scientist might use a flame test when trying to identify a metal ion present in a sample. By observing the color of the flame when the sample is burned, they can determine the presence of specific metal ions based on the characteristic colors emitted. This technique can help in identifying unknown substances in a crime scene or forensic investigation.
A metal sample weights 56.8grams How many ounces does this sample weight?
2.00 oz
What is unknown metal of 158g?
500
What low melting metal did Mendeleev predict?
You think probable to gallium.
An unkown element is shiny and is found to be a good conductor of electircity what other properties would you predict for it?
Based on the properties you described, the unknown element is likely a metal. Metals are typically shiny and good conductors of electricity. You could also predict that it is likely malleable and ductile, as these are common properties of metals.
How can you predict if a metal will replace another in a compound?
You can predict if a metal will replace another in a compound based on the reactivity series of metals. A more reactive metal will displace a less reactive metal from its compound. The position of the metals in the reactivity series will determine whether a displacement reaction will occur.
Why sample oil with metal cans?
Because a plastic bottle can contaminate the sample; and a glass bottle is fragile.
