I'm not quiet sure...possibly an ionic bond.
Answer:
D. Ash is a different substance than wood.
Density is the mass of a substance per unit volume. Volume is the amount of space an object occupies. Chemical properties- These are properties that can only be observed by changing the identity of the substance
Hope it helped ya out!

Answer:
Heat energy (Q) = 334.72
Explanation:
Volume = 4mL
Initial temperature (T1) = 10°C
Final temperature (T2) = 30°C
Mass = ?
Specific heat capacity of water = 4.184J/g°C
Density of water = 1.0g/mL
Heat energy = ?
Density = mass / volume
ρ = mass / vol
Mass = volume × density (ρ)
Mass = 4 × 1.0
Mass = 4g
Heat energy (Q) = mc∇T
Q = heat energy
M = mass of the substance
C = specific heat capacity of the substance
∇T = change in temperature of the substance = T2 - T1
Q = mc(T2 - T1)
Q = 4 × 4.184 ×(30 - 10)
Q = 16.736 × 20
Q = 334.72J
The heat energy required to raise 4ml of water from 10°C to 30°C is 334.72J
