If a substance is ionic, then it likely will what?
Answers
1. Many ionic substances will dissolve completely in water to form an aqueous solution of cations and anions; this solution will conduct electricity.
2. The substance will have a slightly lower melting point than a mid-level covalent network solid.
3. The substance will certainly not conduct electricity as a solid.

The grams of calcium phosphate that can be produced when 89.3 grams of calcium chloride reacted with excess sodium phosphate is
83.08 grams of calcium phosphate
calculation
Step 1: write a balanced chemical equation
3CaCl₂ + 2Na₃Po₄ →6NaCl + Ca₃(PO₄)₂
step 2: find the moles of CaCl₂
moles = mass÷ molar mass
from periodic table the molar mass of CaCl₂ = 40 +( 2 x 35.5) =111 g/mol
moles = 89.3 g÷111 g/mol = 0.805 moles
Step 3: use the mole ratio to determine the moles of Ca₃(PO₄)₂
CaCl₂: Ca₃(PO₄)₂ is 3:1 therefore the moles of Ca₃(PO₄)₂ =0.805 x 1/3 =0.268 moles
Step 4: find mass of Ca₃(PO₄)₂
mass = moles x molar mass
from periodic table the molar mass of Ca₃(PO₄)₂ = (40 x3) +[ 31 +(16 x4)]2 =310 g/mol
mass is therefore =0.268 moles x 310 g/mol =83.08 grams

attracting the heat of the nebular cloud
Answers
Answer: Attracting the heat of the nebular cloud
Heat is lessened by interstellar dust through attraction of heat in the gas cloud. The nebular cloud’s heat, coming from radiation emitted by stars, is indirectly cooled down by dust through ionization and beams it towards space.

b. Carbon, atomic number 6
c. Neon, atomic number 10
d. Fluorine, atomic number 9
Answers
Answer:
Neon, atomic number 10, is stable.
Explanation:
Valencia electrons are the electrons found in the last electronic layer (called valence orbitals). These electrons are what determine the ability of the atom to form bonds. When an element joins another, it does so through its valence electrons.
The noble gases include the elements of group 18 of the periodic table. The noble gases are characterized by their very low chemical reactivity because they are very stable. This is because they have the full valence layer (complying with the octet rule, that is, they have 8 electrons at their last energy level, with the exception of helium that has 2 electrons), causing them to have a low tendency to capture or release electrons . That is why they are also called inert gases.
The Neon, whose atomic number is 10, belongs to the group of noble gases. So this element is stable.
Neon is the most stable because it has 8 valence electrons. when an element has full number of valence electrons, they become stable.
