The correct choice is B.
Mixtures retain their properties because science has proven it. Take a bag of trail mix for example. Those raisins and marshmallows and m&m’s can each be separated. When you take them out, they keep their same texture.
Is not correct because mixtures can be solids (Trail mix is one example)
Correct
Is not correct because sometimes it cannot be seen (Lemonade powder and water is one example)
Is not correct because trail mix is an example.
Yes it is. Copper is the same mass and volume. Plus all pennies are made of copper
Something that can not be undone. Like baking bread..cant be undone.
Answer:
Explanation:
turn over number = R max / [E]t = K2
From given , R max = 249 * 10 ^ -6 mol. L^-1
T [E]t = 2.23 n mol. L^-1
= 2.23 * 10^-9 mol. L^-1
Putting values in above equation,
= 111.65 * 10^3 S^-1
Turn over number is maximum no of substrate molecule that can be converted into product molecules for unit time by enzyme molecule.
