Discuss the likely form of a magnesium/lead alloy that doesnt
form an intermetallic when magnesium is present at low
concentration. Use any relevant information to support your
arguments.
An alloy of magnesium and lead is 50% lead by weight. A) convert
this alloy to an equivalent atomic percentage. B) Convert this
alloy to an equivalent volume percentage
A 0.250-g sample of a magnesium-aluminum alloy dissolves
completely in an excess of HCl(aq). When the liberated H2(g) is
collected over water at 29 ∘C and 752 torr, the volume is found to
be 303 mL . The vapor pressure of water at 29 ∘C is 30.0 torr.
How many moles of H2 can be produced
from x grams of Mg in magnesium-aluminum alloy? The
molar mass ofMg is 24.31 g/mol. Express your answer in terms of
x to four...

A Magnesium Alloy bar 6 in. in diameter is being turned
on a lathe at a depth of cut d = 0.050 in. The lathe is equipped
with a 10-hp electric motor and has a mechanical efficiency of 80%.
The spindle speed is 500 rpm. Estimate the maximum feed that can be
used before the lathe begins to stall.

Discuss briefly how both sedimentary and
igneous rocks form and discuss the likely sources of the magma that
resulted in igneous rocks in Connecticut’s Central Valley.
Magnesium reacts with iron (II) Chloride to form magnesium
chloride and iron. A mixture of 41.0g of magnesium and 175 g of
iron (II) chloride is allowed to react. Identify the limiting
reactant and determine the mass of the excess reactant.
1. When heated, magnesium metal reacts with nitrogen from the air to form magnesium nitride. Write the balanced chemical equation (with phase symbols) for this reaction. 2. Chromium metal reacts vigorously with hydrochloric acid, producing a green solution of chromium(III) chloride and hydrogen gas. The balanced equation for this reaction is: 2 Cr(s) + 6 HCI (aq) → 2 CrCl3 (aq) + 3 H2 (g) In an experiment, a 6.378 g piece of chromium is placed in a beaker containing excess HCI solution. a.
