Answer:

I think 6 miles

Explanation:

6 miles is larger than 30,000 feet.

To compare the sizes of 6 miles and 30,000 feet, we need to convert one of the measurements to the same unit as the other. Since both miles and feet are units of length, we can convert one to the other.

1 mile is equal to 5,280 feet. Therefore, to convert 6 miles to feet, we multiply by the conversion factor:

6 miles × 5,280 feet/mile = 31,680 feet

Now we can compare 31,680 feet to 30,000 feet. Since 31,680 feet is larger than 30,000 feet.

Hence, we can conclude that 6 miles is larger than 30,000 feet.

Model 1 is an ion; Model 3 is an isotope identifies the models that represent an ion and an isotope of the original atom. Therefore, option A is correct.

Isotopes are atoms that have the same number of protons but different numbers of neutrons. They have nearly identical chemical properties but differ in mass and thus in physical properties.

Neutrons exist to stabilize the nucleus without them, the nucleus would be nothing more than a cluster of positively charged protons. There are different isotopes because there are different ways of stabilizing the protons.

Model 1 is an ion and Model 3 is an isotope identifies the models that represent an ion and an isotope of the original atom. The image of the model is attached below:

Thus, option A is correct.

A rain gauge is really just a cylinder that catches rain. If an inch collects in the cylinder, it means an inch of rain has fallen. It's that simple. Most standard rain gauges have a wide funnel leading into the cylinder and are calibrated so that one-tenth of an inch of rain measures one inch when it collects inside.

Answer:

See explanation

Explanation:

When a substance is heated, its average kinetic energy increases as the molecules move faster owing to the supply of energy. The solvent molecules are able to collide more frequently with the solute molecules and dislodge them so that the solute can dissolve in the solvent.

However, when a gaseous solute is dissolved in a liquid; as the temperature is increased and solvent molecules are able to collide more frequently with the solute molecules and dislodge them, gas molecules dissolved in the liquid are more likely to escape to the gas phase and not return due to the increase in their kinetic energy.

Hence, solubility of gas solutes in water decreases as temperature increases.

Answer:

0.112M is molarity of the Na₂S₂O₃ solution

Explanation:

First, the KIO₃ reacts with KI as follows:

KIO3 (aq) + 5 KI (aq) + 6 HCl (aq) → 3 I2 (s) + 6 KCl (aq) + 3 H2O (l)

Then, the I₂ produced reacts with the Na₂S₂O₃ as follows:

2 Na2S2O3 + I2 → Na2S4O6 + 2 NaI

Thus, to solve this question, we need to obtain the moles of KIO₃ that react, then, the moles of I₂ produced -Using the chemical reaction- to find the initial moles of Na₂S₂O₃. With these moles and the volume we can find molarity of the solution:

Moles KIO₃:

21.45mL = 0.02145L * (0.0135mol/L) = 2.896x10⁻⁴ moles KIO₃

Moles I₂:

2.896x10⁻⁴ moles KIO₃ * (3mol I₂ / 1mol KIO₃) = 8.687x10⁻⁴ moles I₂

Moles Na₂S₂O₃:

8.687x10⁻⁴ moles I₂ * (2mol Na₂S₂O₃ / 1mol I₂) = 1.737x10⁻³ moles Na₂S₂O₃

As the volume of the titrated solution is 15.55mL, molarity is:

1.737x10⁻³ moles Na₂S₂O₃ / 0.01555L =
