Answer:
first let's find the molar mass of CH2.Molar mass CH2=12.0+(2multiply1.01)=14.02g/mol

Answer:
B.
Explanation:
ive done this before trust
I feel the exact same way and what I would do is just try talking to them ,it may seem hard at first but try to start a conversation and maybe ask their friends about them or if they still like you
Answer:
2 KF ₍s₎ → F₂ ₍g₎ + 2 K ₍s₎
Explanation:
Chemical Formula of Potassium Fluoride = KF
Chemical Formula of Fluorine Gas = F₂
Chemical Formula of Solid Potassium = K
Step 1: Write the unbalance chemical equation,
KF → F₂ + K
Step 2: Balance Fluorine Atoms;
As there is one fluorine atom on left hand side and two fluorine atoms on right hand site therefore, to balance them multiply KF on left hand side by 2 i.e.
2 KF → F₂ + K
Step 3: Balance Potassium Atoms;
As there are two potassium atoms on left hand side and one potassium atom on right hand site therefore, to balance them multiply K on right hand side by 2 i.e.
2 KF → F₂ + 2 K
Step 4: Assign Physical states as,
2 KF ₍s₎ → F₂ ₍g₎ + 2 K ₍s₎
Fractional distillation is a process by which components in a chemical mixture are separated into different parts (called fractions) according to their different boiling points. Fractional distillation is used to purify chemicals and to separate mixtures to obtain their components.
