Answer:
Polar
Step-by-step explanation:
Electronegativity increases from <em>left to right</em> in the Periodic Table.
Cl is further right than C (both tinted pink) in the portion of the Periodic Table below.
Cl is <em>more electronegative</em> than C, so the Cl has a partial negative charge and the C has a partial positive charge.
The C-Cl bond is polar.
Answer:
Water molecules in the solid state, such as in ice and snow, form weak bonds (called hydrogen bonds) to one another. These ordered arrangements result in the basic symmetrical, hexagonal shape of the snowflake.

Answer:
oxygen is limiting reactant
Explanation:
Given data:
Mass of phosphorus = 25.0 g
Mass of oxygen = 50.0 g
What is limiting reactant ?
Solution:
Chemical equation:
P₄ + 5O₂ → P₄O₁₀
Number of moles of P₄:
Number of moles = mass/molar mass
Number of moles = 25.0 g/ 123.89 g/mol
Number of moles = 0.20 mol
Number of moles of O₂:
Number of moles = mass/molar mass
Number of moles = 50.0 g/ 32 g/mol
Number of moles = 1.56 mol
now we will compare the moles of reactants with product:
P₄ : P₄O₁₀
1 : 1
0.20 : 0.20
O₂ : P₄O₁₀
5 : 1
1.56 : 1/5×1.56 = 0.312 mol
Less number of moles of product are formed by the oxygen thus it will act as limiting reactant.
Answer:
by using the chromatography you can separate different color
Answer: True
Explanation: There are many different types of reactions that can occur during a chemical reaction, a substance dissolving is one of them! often you will notice the following: fizzling, bubbles, color change, odor being produced, smoke. etc.
