There is approximately 1.62g of KF depending on the rounding used
Answer:
Explanation:
Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
Answer:
the degree of ionization in water is high
Explanation:
The term pH is defined as the negative logarithm of hydrogen ion concentration.
Hence;
pH = -log[H^+]
The pH scale shows the degree of acidity or alkalinity of a solution. A solution of pH 1 is a strong acid. A strong acid dissociates completely in solution.
Hence, acid U has a high degree of ionization in water.
it doesn't repopulate as fast because ecosystem 2 could have more trouble reproducing then ecosystem 1.
The three subatomic particles are proton, neutron and electron. Proton and neutron are present inside the nucleus where as the electrons are present revolving in the orbits around the nucleus. Isotopes of the same element have same atomic number but different number of neutrons. Similarly, ions of an element have different number of electrons. For example, neutral Ag atom has 47 electrons, where as 
ion has 46 electrons. Atomic number which is the number of protons is unique for an element. So the number of protons would remain same for different atoms of same element Ag.
