What is o-phthaldehyde?
O-phthaldehyde (OPA) is a small fluorscent molecule that reacts with primary amines, predominantly lysines and N-termins amines, in aqueas solutions at room temperature. It is used to determine the total concentration of protein in a sample. OPA can be used within a concentration of 1µg/ml - 1 mg/ml. Because it will react with N-terminus amines, it is a good choice for assays of small peptides that may not have enough amino acids to be detected by Bradford, BCA or Lowry protein assays.
How many 0.125 mg are in 1 mg?
1 mg ÷ 0.125 mg = 8
How many mg is 100 grams?
1000 mg = 1 o Hence 100 g = 1000 X 100 = 100,000 mg
4100 mg are in how many grams?
4100 mg = 4.1 g4100 mg = 4.1 g4100 mg = 4.1 g4100 mg = 4.1 g4100 mg = 4.1 g4100 mg = 4.1 g
What does enzyme do between o degrees c and 30 degrees c?
What enzyme? There are several. I am pretty sure they don't all react the same.
Is you start with 5 molecules of O in the reaction 2Mg O2 -----2MgO how much Mg will you need?
To react with 5 molecules of O₂, you would need the same number of molecules of Mg. This is because the balanced equation is 2Mg + O₂ → 2MgO. So, you would need 5 molecules of Mg to fully react with 5 molecules of O₂.
What is the word equation of magnesium react with carbon dioxide?
The chemical reaction equation would be Mg + CO2 + O -> ?.
Can Mg react with chlorine with a colored flame?
no
What is the chemical formula for Mg and O?
The chemical formula for magnesium is Mg, and for oxygen, it is O₂.
How 2 moles of Magnesium oxide are formed when 4 moles of Mg reacts with O?
When 4 moles of Mg react with O₂, they will form 4 moles of MgO because the ratio of Mg to MgO is 1:1. Therefore, for every mole of Mg that reacts, one mole of MgO is formed. So, in this case, since there are 4 moles of Mg, 4 moles of MgO will be produced.
Which was does not react with cold water Ca or Mg or Sr or Ba?
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.
What is the chemical formula of Mg and o?
The chemical formula of magnesium is Mg and the chemical formula of oxygen is O.
Does magnesium react with aluminium sulphate?
No.Mg is less reactive than aluminum,therefore mg solution will not react with aluminum metal.
How hydrogen can be prepare at room temperature?
React hydrochloric acid with a metal such as Mg 2HCl+Mg-->MgCl2+H2
What groups do Mg react with?
mostly group 16 or 17 the nonmetals
How many moles of oxygen gas O2 needed to react with 4.00 mol of Mg?
Do you mean this reaction? 2Mg + O2 -> 2MgO 4.11 moles Mg (1 mole O2/2 mole Mg) = 2.06 moles oxygen gas consumed --------------------------------------------------
What is the oxidation number for each element in Mg plus O?
The oxidation numbers for the atoms in magnesium oxide are: Mg+2 and O-2.
