Answer:
D) Xenon
Explanation:
Because this has the largest mass of these elements, it will effuse the slowest.
Answer:
Bigleaf hydrangeas are blue if the pH is between 5.0 and 5.5. The flowers
turn pink when the pH gets around 6.0. The flower color is dependent on
the concentration of aluminum ions (Al+++) in the soil. Aluminum is more
available to the plant when the soil is acidic, less available when the soil is
alkaline.The color of the cultivar called “Endless Summer” of H. macrophylla depends
on soil pH. Red or pink blooms result from neutral or basic soil (pH 7 and
above), whereas blue blooms indicate acidic conditions (pH less than 7).
2CuO+S2 -------> 2Cu + 2SO
There is no graphs attached hence I will provide a rundown of possible discussion points.
Differences/ similarities in trendline data, increase/ decrease/no change in trendline for a certain range of data on the x axis and the degree of change observed (how much increase/ decrease).
Answer:
True.
Explanation:
The mass number of an atom can be calculated using no of protons and the no of neutrons.
Mass number = no of protons + no of neutrons
We can rearrange the above formula to find the no of neutrons as follows :
no of neutrons = Mass number - no of protons
or
Neutrons = Mass - protons.
Hence, the given statement is true.
