Answer: V= 4.2L
Explanation: To solve for the new volume we use Boyle's Law.
P1V1 = P2V2
Derive for V2 the new volume.
V2 = P1V1 / P2
V2 = 1.8 atm x 2.8 L / 1.2 atm
= 4.2 L
Answer:
The active ingredients in baking soda (NaHCO3) are
and
when Baking soda reacts with Acetic acid
Molecular equation
NaHCO3(aq) + CH3COOH(aq) → Na(CH3COO)(aq) + CO2(g) +H2O(l)
Ionic equation
→
as is present on both sides so it will cancel out and the net ionic equation will be
→
Answer:
Explanation:
1. Particles are very far apart. <u>(Gas)</u>
2. Particles are moving quickly. (<u>Liquid</u>, <u>Gas)</u>
3. Particles can flow past each other. (<u>Liquid</u>)
4. Particles are very close together. (<u>Solid</u>)
Gas particles are very far apart from each other and move quickly. Liquid particles can flow past each other and can move quickly. Solid particles are tightly packed together.
An electromagnet can be turned on or turned off which makes it useful for construction purposes to lift heavy metal objects.
