The last photo because its molecular formula is C3H4.
It is B. One single bond and one triple bond.
The statement that true about the temperature of a gas is at <span> a higher temperature, the particles have a higher average kinetic energy. The rest of the choices do not answer the question above.</span>
Answer:
75 g
Step-by-step explanation:
<em>Step 1. </em>Calculate the molar mass of CaCO₃
Ca = 40.08
C = 12.01
3O = 3 × 16.00 = <u> 48.00
</u>
Total = 100.09 g/mol
<em>Step 2</em>. Calculate the mass of the pellet
Mass of CaCO₃ = 0.75 mol × (100.09 g/1 mol)
Mass of CaCO₃ = 75 g
