Because the reaction occurs between a metal and non metal
CL=2,8,7
C
Answer:
Chemical Equation Balancer C2H2 + O2 = CO2 + H2O.
Explanation:
A catalyst has no effect on the equilibrium state, but it enables equilibrium to be reached more quickly by decreasing the “energy of activation”. In fact, a catalyst affects forward and reverse rates equally.
Answer:
1.02x10^24 atoms
Explanation:
The coefficients (the numbers before each susbtance) in this equation tell us that for every 2 moles of hydrogen used, there will be 1 mole of tin produced. This is a fixed ratio, which means if we use 4 moles of H2, 2 moles of tin will be produced.
One mole contains Avogadro's number of atoms (6.02 x 10^23). So two moles would contain twice as many atoms as this.
2 x 6.02x10^23 = 1.02x10^24 atoms.
