Tyrone and Valerie wanted to determine what feature of a paper airplane would cause it to fly the farthest. Tyrone made his airp

lane with wider wings than Valerie’s airplane. Valerie’s airplane had shorter wings, and the plane was also narrower and longer than Tyrone’s. After testing the two airplanes several times, the evidence shows that Tyrone’s airplane flew farther through the air than Valerie’s airplane.
Describe why the investigation above is not adequate to explain which airplane feature caused Tyrone’s airplane to fly farther than Valerie’s.

Using what Tyrone and Valerie have already observed, suggest a possible hypothesis regarding one feature of a paper airplane.

Identify the independent and dependent variables. Describe, in detail, a procedure to test your hypothesis. Identify the controlled variables.

enyata [817]

Answer:

Explanation:

In CF4 and NF3, the valence electron groups on the central C and N atoms have a tetrahedral arrangement. The shapes of the molecules are determined by the number of bonding and nonbonding of electrons: since CF4 has four bonded atom(s) and zero lone pair(s) of electrons, the shape is tetrahedral.

Why is a chemical equilibrium described as dynamic?
Katen [24]
Because when equilibrium is reached, the reaction is still occurring in both directions, it's just that rate(forward) =rate(reverse) so there is no net change in the concentrations of the reactants or products.

Calculate ΔG o for the following reaction at 25°C: 3Mg(s) + 2Al3+(aq) ⇌ 3Mg2+(aq) + 2Al(s) Enter your answer in scientific notat
larisa [96]

Answer:

-3.7771 × 10² kJ/mol

Explanation:

Let's consider the following equation.

3 Mg(s) + 2 Al³⁺(aq) ⇌ 3 Mg²⁺(aq) + 2 Al(s)

We can calculate the standard Gibbs free energy (ΔG°) using the following expression.

ΔG° = ∑np . ΔG°f(p) - ∑nr . ΔG°f(r)

where,

n: moles

ΔG°f(): standard Gibbs free energy of formation

p: products

r: reactants

ΔG° = 3 mol × ΔG°f(Mg²⁺(aq)) + 2 mol × ΔG°f(Al(s)) - 3 mol × ΔG°f(Mg(s)) - 2 mol × ΔG°f(Al³⁺(aq))

ΔG° = 3 mol × (-456.35 kJ/mol) + 2 mol × 0 kJ/mol - 3 mol × 0 kJ/mol - 2 mol × (-495.67 kJ/mol)

ΔG° = -377.71 kJ = -3.7771 × 10² kJ

This is the standard Gibbs free energy per mole of reaction.
