Explanation:

The time taken by the plane to reach its destination can be found by using the formula

[tex]t = \frac{d}{v} \\ [/tex]

d is the distance

v is the velocity

From the question we have

[tex]t = \frac{395000}{4500} = \frac{3950}{45} = \frac{790}{9} \\ = 87.77777...[/tex]

Answer:

You can infert that it has a mass of 40 grams.It also has desnity of 40 grams per millilieter.

Explanation:

The volume of water raised from the glass is equal to the density of the object which displaces water. Hence, 40 g/ml is the density of the rock.

The Greek mathematician and inventor Archimedes discovered the physical law of buoyancy, which states that any body completely or partially submerged in a fluid (gas or liquid) at rest is subject to an upward, or buoyant, force whose magnitude is equal to the weight of the fluid displaced by the body.

The volume of fluid that has been displaced is equal to the volume of an object that is completely submerged in the liquid or to the portion of the volume below the surface for an object that is only partially submerged.

Therefore, the density of the rock is equivalent to the volume of water level raised in the glass. Thus density of rock is 40 g/ml.

Answer:

5.595 g Fe

General Formulas and Concepts:

Chemistry - Stoichiometry

Explanation:

Step 1: Define

16.25 g FeCl₃ (Iron III Chloride)

RxN:   2Fe + 3Cl₂ → 2FeCl₃

Step 2: Identify Conversions

Molar Mass of Fe - 55.85 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of FeCl₃ - 55.85 + 3(35.45) = 162.2 g/mol

Step 3: Stoichiometry

[tex]16.25 \ g \ FeCl_3(\frac{1 \ mol \ FeCl_3}{162.2 \ g \ FeCl_3} )(\frac{2 \ mol \ Fe}{2 \ mol FeCl_3} )(\frac{55.85 \ g \ Fe}{1 \ mol \ Fe} )[/tex] = 5.59533 g Fe

Step 4: Check

We are given 4 sig figs. Follow sig fig rules and round.

Answer:

Neutrons are located in the nucleus with protons.

Explanation:

Neutrons are located in the nexus of a snippet along with protons. The nexus is the mediate portion of a snippet that contains the utmost of its body.

Protons convey a good count, while neutrons are neutral and don't convey an electric count. Electrons, on the different side, are located in route around the nexus, enwrapping snap situations or electron coverings.

Neutrons are subatomic patches that are one of the immediate ingredients of infinitesimal capitals. They're generally imported by the logo "n or no". Neutrons don't hold any net electric count companies with them.

They befit, still, own a body that's scarcely lesser in significance than that of a proton. Neutrons and protons are inclusively appertained to as nucleons since they bear analogous proprieties inside the capitals of titles.

Answer:

An air mass that is described as having warm and moist air is called maritime tropical. This occurs when heat and moisture are transferred to the overlying air from the warm waters of the ocean or seas. Maritime Tropical air mass comes from the warm waters of the tropics and the Gulf of Mexico. When warm air moves northward moist air is transported to the United States which causes the increase in precipitation. Maritime Tropical masses are often felt in the Southeast part of the United States.

Answer:

smallest to largest:

Electron, Neutron, Atom, Molecule, Nucleus

Explanation:

sorry if it's not right

Electron--Neutron--Nucleus-- atom--Molecule is the order from smallest to largest.

Electron is the smallest subatomic particles having the radius is about 9.1× 10−31 kg while on the other hand, the size of neutrin is 1.7×10−15 meters. Both neutron and proton are present in the nucleus so nucleus is bigger than neutron. Nucleus is present inside an atom so atom is bigger than nucleus whereas atom is smaller than molecule.

So we can conclude that Electron--Neutron--Nucleus-- atom--Molecule is the order from smallest to largest.

Answer:

See explanation

Explanation:

The question is incomplete. However, base on the given information, one likely question could be that, we calculate the the volume of the nitrogen gas after heating it.

So, we have that:

Initial Volume, V1 = 200mL

Initial Temperature, T1 = 24k

Final Temperature, T2 = 47k

To solve the final volume of the gas, we apply the following ideal gas law equation

V1 * T1 = V2 * T2

Substitute values for V1, T1 and T2

200mL * 24K = V2 * 47K

200mL * 24 = V2 * 47

4800mL = 47V2

Solve for V2

V2 = 4800/47

V2 = 102.13 mL ------- Approximated

Hence, the volume of nitrogen gas after heating is 102.13mL
