Answer:
A neap tide can occur for position A but not for position B.
Explanation: Position B is a spring tide.
Answer:
D
Explanation:
Both images have 4 protons (positive particles) and 4 electrons (negative particles) so in total they don't have a charge. (<em>you don't have to worry about neutrons in this case, because they don't have a charge.)</em>
An ion has a charge so neither image is an ion
Answer:
11690J
Explanation:
Use formula Q = mL
where:
Q = Energy (J)
m = Mass (g)
L = Latent heat of fusion for water (J/g) = 344J/g
Therefore:
Q = 35.0 x 344
Q = 11690J
Explanation:
The Chemical Equations are;
H2CO3 --> H2O + CO2
8Cu + S₈ --> 8 Cus
BaCO3 --> BaO + CO2
P₄ + 502 --> 2P205
KCIO3 --> KCI + O2
8Fe + S₈ --> 8Fes
The Reactions are;
Synthesis Reaction
Decomposition Reaction
A synthesis reaction occurs when two atoms or molecules react to form a different molecule or compound.
A decomposition reaction; a compound breaks into two or more products.
H2CO3 --> H2O + CO2 (Decomposition reaction)
8Cu + S₈ --> 8 CuS (Synthesis reaction)
BaCO3 --> BaO + CO2 (Decomposition reaction)
P₄ + 502 --> 2P205 (Synthesis reaction)
KCIO3 --> KCI + O2 (Decomposition reaction)
8Fe + S₈ --> 8Fes (Synthesis Reaction)
