Explanation:
Normally, fusion involves two heavy hydrogen nuclides but since we have 4 light hydrogen nuclides, two of which underwent positron emission, thus changing two protons into neutrons plus 2 positrons and 2 neutrinos. The resulting nucleus from this fusion reaction is an He-4 nucleus.
Answer:
So you should go and try to divide or smth or multiply
Answer:
it is option 2.
Explanation:
when balancing equations, both sides need to have the same number of the element.
4As + 3O2 - -> 2As2O3
4 as. 4 as (2×2=4)
6 o (because 3×2=6) 6 o (2×3=6)
since there are the same amount of each element on both sides, the equation is balanced.
hope this helps:)
Answer:
P = 138.64 atm
Explanation:
Given data:
Volume of helium = 1.2 L
Number of moles = 6.8 mol
Temperature = 25°C (25+273 = 298 K)
Pressure of gas = ?
Solution:
Formula:
PV = nRT
R = general gas constant = 0.0821 atm.L/ mol.K
P = nRT/V
P = 6.8 mol × 0.0821 atm.L/ mol.K × 298 K / 1.2 L
P = 166.4 atm / 1.2
P = 138.64 atm
