Answer:
Explanation:
Every A will be paired with a T, and every C with a G and vice versa (T to A, and G to C)
So the first letters in the sequence are ATGGG. So the pair will be TACCC.
Answer:
Concentration
Explanation:
Concentration is measure of the quantity of solute present in a given amount of solvent. Concentration can be measured in mol/dm³, g/m³ and other forms like molality, parts per million.
Concentration in mol/dm³(molarity) is a measure of the amount of moles of solute present in 1 dm³ of solvent while concentration in g/dm³ is the number of grams of solute present in 1 dm³ of solvent. These units of concentration can be converted to the other unit by using simple conversion methods.
molality refers to the amount of solute in 1 kg of solvent, while ppm is basically used for very dilute solutions.
Answer: Mass is the amount of matter in a substance. Volume is the amount of space matter takes up. Matter has both physical and chemical properties.
Explanation:Y w
3Mg + N₂= Mg₃N₂
n(Mg)=12,2g÷24,4g/mol=0,5mol-limiting reagentn
(N₂)=5,16g÷28g/mol=0,18mol
n(Mg₃N₂):n(Mg)=1:3, n(Mg₃N₂)=0,166mol, m(Mg₃N₂)=0,166·101,2=16,8g.
%(N)= 2·Ar(N)÷Mr(Mg₃N₂) = 2·14÷101,2=27,66%=0,2766
%(Mg) = 3·Ar(Mg)÷Mr(Mg₃N₂)= 3·24,4÷101,2=72,34% or 100% - 27,66%= 72,34%.
