You put a coefficient before the molecular formula, or multiply the coefficient already there by a number. For example, five molecules of carbon dioxide (CO2) would be 5CO2 (with the two as a subscript).
Answer:
Since they have an electronegativity difference of 0.4 then they will form a Covalent Bond.
Answer:
CaCl₂
Step-by-step explanation:
The <em>empirical formula</em> is the simplest whole-number ratio of atoms in a compound.
The ratio of atoms is the same as the ratio of moles.
So, our job is to calculate the molar ratio of Ca to Cl.
Data:
Mass of Ca = 3.611 g
Mass of Cl = 6.389 g
Calculations
Step 1. <em>Calculate the moles of each element
</em>
Moles of Ca = 3.611 g Ca × (1 mol Ca/(40.08 g Ca)= 0.090 10 mol Ca
Moles of Cl = 6.389 g Cl
Step 2. <em>Calculate the molar ratio of the elements
</em>
Divide each number by the smallest number of moles
Ca:Cl = 0.090 10:0.1802 = 1:2.000
Step 3. Round the molar ratios to the nearest integer
Ca:Cl = 1:2.000 ≈ 1:2
Step 4: <em>Write the empirical formula
</em>
EF = CaCl₂
Answer:
The lithosphere is broken into separate sections called plates. The geological theory that states that pieces of Earth's lithosphere are in constant, slow motion, driven by convection currents in the mantle is plate tectonics.
