Based on the methods used in the video, answer the following gram to gram conversion question: 2 C2H6 + 7 O2 > 4 CO2 + 6 H2O

In the combustion of ethane (C2H6), 4.12 grams of water (H2O) was produced. How much ethane (C2H6), in grams, was used in this reaction?

molar mass H2O= 18.02 g/mol

molar mass C2H6= 30.08 g/mol

2.47 g C2H6

2.29 g C2H6

20.63 g C2H6

20.97 g C2H6

B

Explanation:

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
