Answer:
10 L
Explanation:
The only variables are pressure and volume, so we can use Boyle's Law:
p1V1 = p2V2
Data:
p1 = 125 atm; V1 = 4.0 L
p2 = 50 atm; V2 = ?
Calculation:
125 × 4.0 = 50V2
500 = 50 V2
V2 = 500/50 = 10 L
The new volume will be 10 L.
Answer:
positron
Explanation:
A positron is a particle produced when a proton is transformed into a neutron. Anti neutrinos are ejected from the nucleus to balance spins.
Positron emission increases the Neutron/Proton ratio. When a nuclide undergoes positron emission, the atomic number of the daughter nucleus is one unit less than that of the parent nucleus hence it is found one place before its parent in the periodic table.
If one of the parents have a genetic for a disease or illness, but one of them has a genetic for immunity for that disease then the offspring may be benefitted. ( Not 100% sure tho)
NH₄Cl (s) ⇔ NH₃ (g) + HCl (g)
Δn = 2 (gas only)
R = 0.082
T = 427 + 273 = 700 K
4.8 = Kc (0.082 x 700)²
Kc = 1.45 x 10⁻³
Something that can be observed, measured or changed without altering the identity of a substance is called a physical property. The correct answer is A.
