It Could be Boron

What questions would you ask a science teacher?
The question that you could ask a science teacher is why the glaciers are melting. You could also ask about DNA, plants, animals, or even atmospheric pressures.
If you were supposed to ovulate on February 26 and had intercourse how soon could you take a pregnancy test?
Usually 8 days after intercourse is the soonest that you can accurately tell if you are pregnant or not.
Why could the rate of heating influence the melting?
It doesn't. Melting point is fixed for each substance at a particular pressure. However, very rapid heating can make it difficult to measure the melting point accurately.
Can you mend exhausts by soldering?
Welding or brazing perhapsReplacement is best Solder has too low a melting point to be good in such a high temperature environment. After running the car for a few miles, you could apply the solder to the muffler and it will melt without a torch or soldering iron.
What substance has the lowest freezing point?
Mercury Hg -38.8' Now you could consider Hydrogen to be a metal if you are willing to get creative with the definition of metal. In that case it would be −259.16 °C
Is silver solder 100 percent silver?
No. 100% silver would be pure silver. Noble silver, Argentium nobalis. which is super soft and shiny. it is very difficult to tarnish. Silver solder is an alloy. An alloy being a mixture of metals. Hard solder is around 67% silver eg. the amount of silver generally goes down as its melting temperature goes down. Soft solder is likely around 45% eg. it could vary massively from company to company and application. A recipe for hard solder is. 1/2 parts tombac brass, to 1 part pure silver. Adding 5% zinc to this, would lower its melting temperature enough to call it softer solder for aplication. Caution, careful of this recipe for jewelry application. it might not meat your countries standard for silver content and you could be breaking the law. Research the percentage of silver necessary to meat the requirements. do not add metals to it you know nothing about. You could hurt someone. All of this should be do buy someone with good knowledge.
Is solder heterogenous or homogenous?
It could be either. Any type of liquid core solder (acid core, rosin core, etc.) is heterogenous, since there's the metal part and the core part. A solid-core solder is probably homogeneous.
Which physical properties could be the basis for separating the metals that are mixed to make an alloy 1 color2 melting point 3atomic mass 4atomic number?
To physically separate them you'd have to use melting point. Heat the mixture up and the element with the lowest melting point will become liquid first. None of the others are methods of separating components, just ways of describing them.
How tin used for in a mobile phone?
Tin could be in a mixture with lead to form the solder. Solder is used to hold the components to the printed circuit board.
How could the identify of a compound be established by melting point?
Pure substances have very specific melting (and boiling) points. Assuming the substance is pure you could measure the melting point and compare it to a known database of melting points.
What happens to neon during melting point?
There are a number of things that could happen to neon while it is at its melting point. It could melt.
What transition metal has the lowest melting point?
Knowing what the options are for the answers would be helpful to know which has the lowest melting point. Without knowing what transition metals are listed in the answers it is hard to know which is correct.
Who could not predict the movements of the planets accurately?

Leading up to the Civil War the southern states could accurately be described as federalist.
