Answer:
The new volume is 87.5 ml.
Explanation:
We have,
Volume of sample of neon is 175 ml
The pressure changed from 75 kPa to 150 kPa.
We need to find new volume.
It is based on the concept of Boyle's law. Let V₂ is new volume. So,
So, new volume is 87.5 ml.
The answer is Isotope. Isotopes; each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element. For example, carbon-12, carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12,13 and 14 respectively.
A. Bond polarity is directly related to electronegativity difference. The greater the difference in electronegativity the more polar the bond.
<span>b. When two elements are next to one another in the periodic table they have similar electronegativities. Chlorine has a value of 3.0 while bromine has a value of 2.8. These two atoms in Br-Cl would have a nonpolar covalent bond.</span>
