Which statement is correct about CH4?

Option 2 is correct. CH4 is the chemical formula for methane. It is a symmetrical molecule which shows tetrahedral geometry. It is also an overall non polar molecule.

How do you write CH4?

What type of bonding is CH4?

covalent bonds
Methane, CH4, is a covalent compound with exactly 5 atoms that are linked by covalent bonds. We draw this covalent bonding as a Lewis structure (see diagram). The lines, or sticks, as we say, represent the covalent bonds. There are four bonds from a central carbon (C) linking or bonding it to four hydrogen atoms (H).

What is the standard enthalpy of the reaction CH4 g2 o2 g2 CO2 g 2H2O L <UNK>?

Limitation of using average bond enthalpies We earlier calculated using average bond enthalpies that for the reaction CH4 + 2O2 → CO2 + 2H2O ΔH = -708 kJmol-1. The published value for ΔcHΘ for this reaction is -890 kJmol-1.

How do I calculate enthalpy?

Use the formula ∆H = m x s x ∆T to solve.

Once you have m, the mass of your reactants, s, the specific heat of your product, and ∆T, the temperature change from your reaction, you are prepared to find the enthalpy of reaction. Simply plug your values into the formula ∆H = m x s x ∆T and multiply to solve.

Which of the following processes is exothermic quizlet?

Which one of the following processes is exothermic? Condensation of a gas into a liquid. An exothermic process releases heat. Boiling a liquid, melting a solid and converting a solid into a gas all require energy be put into the system.

How do you find the mass of CO2?

How do I find molar mass?

The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.
