Answer:
d. The acid is likely to eat through the can.
Explanation:
Aluminium is a metallic element found in group 3 of the periodic table. Aluminum is a very reactive metal owing to the fact that it reacts with almost every substance it comes in contact with e.g air, acids, bases etc.
In this question where Derek stores his Hydrochloric acid (HCl) remnant, after an experiment, into a can made of aluminum. What will happen is that the acid is likely going to eat through the can. This might occur gradually but will eventually. Aluminum protects itself from further reactions by forming a layer of Aluminum oxide (Al2O3) when it reacts with air.
This is what keeps the reaction with HCl gradual but the acid will eventually permeate the layer and corrode the aluminum can by reacting with the aluminum.
Answer:
P₄ + 5O₂ → 2P₂O₅
Explanation:
Phosphorus burn in the presence of air and produced diphosphorus pentoxide.
Chemical equation:
P₄ + O₂ → P₂O₅
Balanced chemical equation:
P₄ + 5O₂ → 2P₂O₅
Equation is balanced because there are four phosphorus atoms ans ten oxygen atoms in both side of equation.
Coefficient with reactant and product:
P₄ 1
O₂ 5
P₂O₅ 2
Answer:
D- Kinetic Molecular Theory
Explanation:
. Gases consist of large numbers of tiny particles that are far apart relative to their size.
.Collision between gas particles and between particles and container walls are elastic collisions.
.Gas particles are in continuous motion. possess kinetic energy.
. Gas molecules have negligible intermolecular forces.
. Gas molecules have an average kinetic energy proportional to the ideal gas's absolute temperature.
Answer:
the density of the sample - the melting point of the sample
Explanation:
Intrinsic property is the property of matter which exists itself or within subject. In other words, it do not depend on the mass of the sample. An extrinsic property is not inherent or essential to subject which is being characterized. In other words, it depend on the mass of the sample.
For example,
Density, melting point are example of intrinsic property. Whereas, weight, volume are an example of extrinsic property.
Intrinsic properties helps to determine the matter. Thus, density of sample and melting point of sample is the answer.
Percent Mass Percent/mass lowest # #
C 85.64 12 7.13666 /7.1366 1
H 14.36 1 14.36 / 7.1366 2
CH2 this is not in its molecular formula yet the mass doesn't equal 42.08
(CH2)3 mass = 42
It's molecular formula is C3H6
