Answer: An atomic number of 8
Explanation:
All oxygen atoms have an atomic number of 8 in common, but could differ in mass number in their isotopes.
Examples of oxygen atoms are O16, O17, and O18. They all have an atomic number of 8, but different mass numbers of 16, 17, and 18 respectively. Thus, they are isotopes of oxygen.
Answer:
the gas particles strike the walls of the container more often
Explanation:
Following Boyle's law, if the amount of gas and the temperature remain constant, the product of the pressure for the volume remains constant, but when altering any of these conditions this value changes and is expressed through the equation:
<em> </em>
<em></em>
So, when the volume decreases, the distance that the particles have to travel is smaller and therefore more collisions between particles and between the walls occur per unit of time, that is, the system pressure increases.
Answer:
New volume = 8.00 Liters
Explanation:
Boyles Law => P₁V₁ = P₂V₂
P₁ = 1.0 Atm
V₁ = 20.0 L
P₂ = 2.5 Atm
V₂ = ?
P₁V₁ = P₂V₂ = V₂ = V₁(P₁/P₂) = 20.0L(1.0Atm/2.5Atm) = 8.00L
Answer & explanation:
To balance a chemical equation, we must make sure that there are equal amounts of each element in the equation on either side.
To balance an equation step-by-step we first start by counting the amount of each element on each side. If they aren't equal, we must make them amounts equal on either side.
After you make sure all the elements are balanced, the net charge on both sides must also be equal.
