Answer: daughter nucleus is Oxygen-17
Explanation: electron and proton form a neutron in nucleus.
Mass number remains same and number of proton decreases.
Answer:
not sure about the first one, but i know SDS provides information about the last 3.
Explanation:
Answer: V= 1.87 L
Explanation: Use Charles Law to solve for the new volume.
V1/T1 = V2/T2 where temperature is in Kelvin. So convert temperature to Kelvin.
4 L ( 175 K ) / 375 K
= 1.87 L
Cancel out both units of K.
<span>It rises confidence for the reason that the more times you conduct the similar experiment over and over should either demonstrate your hypothesis right and wrong and remove any random incidences that might touch your results. Meaning it permits to have a more accurate measure or conclusion.</span>
Molarity = (Mass/ molar mass) x (1/ volume of solution in Litres)
Mass = Molarity x molar mass x volume of solution in Litres
Molarity of Tris = 100 mM = 0.1 M
volume of Tris sol. = 100 mL = 0.1 L
molar mass of Tris = 121.1 g/mol
Hence,
mass of Tris = Molarity of Tris x molar mass ofTris x volume of Tris solution
= 0.1 M x 121.1 g/mol x 0.1 L
= 1.211 g
mass of Tris = 1.211 g
