What is a metallic solid? What is a conductivity in chemistry? Why do ionic bonds have high melting points? What properties characterize ionic compounds? What kind of crystalline solid is MgCl2? What nonmetal forms an ionic compound with aluminum so that it has the formula Al2X3 where x repr...
Is MgCl2 ionic or covalent? Are crystalline solids ionic? Are nonmetals reactive? Is lawrencium a metal? What is sodium chloride? Is salt an amorphous solid? Is sodium fluoride ionic, covalent, or polar covalent? Is vanadium a metal, nonmetal or metalloid?
Electronegativity trends are present in the periodic table, in which the electronegativity increases going right across a row and up a group. Therefore group 1 metals will have very low electronegativity relative to group 7 elements (halogens). Combining two elements with strong...
The binding conditions for AP-1 (CGCTTGATGACT-CAGCCGGAA) and GATA (CACTTGATAACAGAAAGTGATAACTCT) oligonucleotides were the same as that for NF-κB except 50 mM KCl and 10 mM MgCl2 were substituted for 50 mM NaCl. Agarose-conjugated anti-p65 antibody (100 μg of IgG/ml) was incubated...
aDifferential extraction assay separates discrete assembly states of NF-L. Low ionic strength, low-order assembly states; high ionic strength, intermediate assembly states; 8 M urea, fully assembled NFs.b293T cells were transfected with NF-L-myc-6xHis ± OGT-myc for 24 h and analyzed by...
was therefore carried out to determine whether there Studies of halophilic Archaea and Bacteria is a common water-activity limit for the three capable of growth in MgCl2-rich and/or NaCl-rich domains of life; we hypothesised that: (1) halophilic media (Figures 1b–f and 2) were carried ...
One unit of DNase I (Promega) in 20 μl of DNase I buffer (10 mm Tris-HCl, 10 mm MgCl2, 2 mm CaCl2, 1 mm DTT, 15 mm NaCl, pH 7.5) was then added, mixed, and the digestion allowed to proceed for exactly 1 min at 22 °C before being terminated with the addition of 40 μ...
Magnesium reacts with iron(II) chloride according to the equation: Mg(s) + FeCl2(aq) \rightarrow MgCl2(aq) + Fe(s) Magnesium is oxidized. True False Most chemical reactions are reversible to some extent. a. True. b. False. The equation, D + F + heat --> ...

Will 1 L of 1 M NaCl contain more chloride ions than .5 L of 1 M MgCl2? Explain. Why is the term molecular mass inappropriate for NaCl? Why does RbBr + NaCl form no chemical reaction? How do you know this? Why is NaCl described as a strong electrolyte?
