Answer:
The flask has to be closed during the hydrochloric acid and sodium carbonate reaction as the resultant gas got trapped inside the closed flask.
Explanation:
The hydrochloric acid and sodium carbonate reaction was exothermic that caused the pressure to decrease. The flask has to be closed during the hydrochloric acid and sodium carbonate reaction as the resultant gas got trapped inside the closed flask.
In exothermic reactions, energy is produced in the form of heat or light.
Answer: #1 The poppy seeds represent the protons, electrons and neutrons
#2 The fiberfill represents the nucleus #3 Protons and neutrons are in the nucleus #4 Electrons are the particles that are surrounding the nucleus #5 Because they are representing different things and they are their own entity

Answer:
101.63° C
Explanation:
Volume expansivity γa = γr - γ g = 18 × 10⁻⁵ - 2.0 × 10⁻⁵ = 16 × 10⁻⁵ /K
v₂ - v₁ / v₁θ = 16 × 10⁻⁵ /K
(500 - 492 ) mL / (492 × 16 × 10⁻⁵) = θ
θ = 101.63° C
Answer:
If a linear graph has a negative slope then dependent value decreases in value as the independent variable increases. The line with negative slope is sloping down to the right
