Answer:
21.8 g/mol
Explanation:
Molecular weight of CH4 = 16g/mol
H2 = 2g/mol
N2 = 28g/mol
(16*30 + 2*10 + 28*60)/100
=2180/100
=21.8g/mol
Heat energy = MCΔT; where m is the mass, c is the specific heat capacity; while ΔT is the change in temperature.
Mass is 100 g , while change in temperature 50°C and heat energy is 23.5 kJ or 23500 j
Hence; 23500 = 100 × c ×50
c = 23500/5000
= 4.7 j/g/°c or 4700 J/Kg/°C
The substance is ammonia since it has the specific heat capacity is 4.7 J/g/°C
The answer for this mathematical problem would be 27.922 because the word “product” means your answer after multiplying. So when they the product of (x) they mean blah (23.0 in this case) times blah (1.214 in this case) :)
Answer:option d is the ans
Explanation:When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION. If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is a positive ion.
