when methane reacts with oxygen, the products are carbon dioxide and water. How many grams of carbon dilxide are formed if 30 g
Wittaler [7]

Answer:

CH4+2O2→CO2+2H2O

Moles of oxygen=3232=1

Moles of carbon dioxide=4422=0.5

Moles of water=1818=1

1 mole of methane reacts with 2 moles of oxygen to give 1 mole of CO2 and 2 moles of water so 0.5 mole of methane will be required which is equal to 0.5×16=8g.

Explanation:

8g

yKpoI14uk [10]
<h3>Answer:</h3>

A coordinate bond

<h3>Explanation:</h3>
  • A chemical bond is a force of attraction between two or more atoms of elements.
  • Covalent bond is a type of chemical bond that occurs between non-metal atoms.
  • It occurs as a result of sharing of electrons between the non-metal atoms.
  • Atoms involved in covalent bond formation may contribute equally to the bond formation or the electrons shared may come form one of the atoms.
  • When the electrons shared in a covalent bond are derived from one atom, then the covalent bond is known as a coordinate bond.
