Yes it's very good for you. It lowers cholesterol and is full of Omega 3 and natural oils.
What metal is the best conductor of heat aluminium iron or brass?
Aluminum have better thermal conductivity than ironAluminum: 205W/(m K)Iron: 80 W/(m K)
Why does carbon conduct electricity if it is a non metal?
Carbon is used as a conductor in many applications. One common conductor, automotive spark plug wires, is actually a carbon impregnated chord. A common problem in high voltage electrical systems, such as automotive ignition secondary circuits, is "carbon tracking". A distributor cap, for example, may arc from one terminal to another, leaving a carbon track behind. The current will now follow that carbon path very readily and this is one reason secondary circuit (high voltage) components have to be replaced periodically.
What elements are combine to form a ruby?
A ruby is a pink to blood-red gemstone, a variety of the mineral corundum (aluminium oxide). The red color is caused mainly by the presence of the element chromium.It is not a chemical compound with fixed ratios of elements, it is essentially Al2O3 with some Al3+ replaced by Cr3+
Is AlPO4 ionic or covalent bonded?
IONIC is the best answer at High School level. . However AlPO4, anhydrous form is a mineral berlinite that looks remarkably like SiO2, silica (quartz) and has the same crystal structure, half the silicon atoms are replaced with aluminium and half by phosphorus and the bonding is actually better described as covalent. AlPO4 is usually encountered as a hydrate or even as a "sol-gel".

How did pencils change since it was created?
Very little. The earliest pens had their graphite core wrapped in leather or string; but already in the mid-sixteenth century the wooden pencil like the one we still have today was invented. And the pure, solid graphite core has over time been replaced by a core of graphite powder mixed with clay.
What is the chemical composition of the June birthstone?
Alexandrite is a type of chrysoberyl, BeAl2O4, in which a small percentage of the aluminium atoms have been replaced by chromium atoms.
Why is it necessary to periodically assess and evaluate policies?
is it necessary to have periodically assess and evaluate policies because it determines whether the policies are still current & relevant to your organisation & to its clients. Whether the policies suits their intended purpose or whether they need to be changed, eliminated, replaced or even updated.

The pre-civil war (1934) Spanish 5 Peseta coins were made from .900 silver. From 1949 they were made of Nickel until switching to an alloy of Aluminium and Bronze in 1989, which was used until they were replaced by the Euro in 2001.
