The water cycle describes the continuous movement of water on earth. Which part of the water cycle is directly responsible for returning water to the soil

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.

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.

similarly when you drink a glass of fruit juice your blood glucose goes up

homeostasis depends on that ability of your body to detect and oppose these changes

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.

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: m = 24.31 g/mol · 1.13 mol

Explanation: 2 mol HCl use 1 mol Mg.

Magnesium is used 0.5 · 2.26 mol = 1.13 mol

M(Mg) = 24.31 g/ mol

27.50 grams of magnesium were used in the reaction.

Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray metal that is relatively soft and lightweight. Magnesium is the eighth most abundant element in the Earth's crust and is found in minerals such as magnesite and dolomite.

The balanced chemical equation is: Mg + 2HCl ⟶ MgCl2 + H2. From the equation, we can see that one mole of magnesium reacts with 2 moles of hydrochloric acid to produce one mole of magnesium chloride and one mole of hydrogen gas.

We are given 2.26 moles of hydrochloric acid, which means that we need half as many moles of magnesium to react with it. So: moles of Mg = 2.26/2 = 1.13

Now we can use the molar mass of magnesium (24.31 g/mol) to calculate the mass of magnesium used in the reaction:

mass of Mg = moles of Mg x molar mass of Mg

mass of Mg = 1.13 mol x 24.31 g/mol

mass of Mg = 27.50 g

Answer:

-1464 kJ/mol

Explanation:

The balanced equation for the reaction is given as;

C2H4(g)+3O2(g)→2CO2(g)+2H2O(l) ΔH∘1=?

The enthalpy of the reaction is given by the equation;

Enthalpy of reaction = Enthalpy of products - Enthalpy of reactants

Products:

2CO2(g)+2H2O(l)

Enthalpy of Products = 2 (−394) + 2(−286)

Enthalpy of Products = -1360 kJ/mol

Reactants:

C2H4(g)+3O2(g)

Enthalpy of Reactants = 2 (52) + 3(0)

Enthalpy of Reactants = 104 kJ/mol

Enthalpy of Reaction =  -1360 - 104 = -1464 kJ/mol
