a cylindrical object has a diameter of 1.25 cm and a height of 6.48 cm. what is its volume?

Answers

The volume of cylinder = 7.948 cm³

Further explanation

Volume is a derivative quantity derived from the length of the principal

The unit of volume can be expressed in liters or milliliters or cubic meters

The volume of the aquarium is almost the same as the beam namely:

V = length x width x height

The volume of a cylinder can be formulated :

[tex]\tt V=\pi.r^2.h[/tex]

r = radius

h = height

radius

Diameter of cylinder = 1.25 cm

radius=r :

[tex]\tt \dfrac{1.25}{2}=0.625~cm[/tex]

volume

[tex]\tt V=\pi\times 0.625^2\times 6.48\\\\V=\boxed{\bold{7.948~cm^3}}[/tex]

Explain why the mass number of oxygen is 16

Select the molecular shape of each molecule based on the formula or Lewis structure.

Answers

Answer:

1. linear (A)

2. trigonal-planar (C)

3. tetrahedral (B)

4. linear (A)

Explanation:

Just did it on Edge 2020

The shape of a molecule can be predicted from the number of electron pairs that surround the central atom in the molecule.

The Valence Shell Electron Pair repulsion theory gives us a basis for predicting the shape of molecules. The shape of a molecule can be predicted from the number of electron pairs that surround the central atom in the molecule.

In the image shown, We can see that in HCN , carbon is the central atom and is surrounded by two atoms and no lone pairs. Since there are two electron domains around the central atom, the molecule is linear.

In the second structure, BH3 has boron as its central atom. Three electron domains surround the central atom hence the molecule is trigonal planar.

A piece of gold has a mass of 21.7 kg and a volume of 5.78 cm3 . What is the density of gold? (Convert kgg)

Answers

Answer:

The answer is 3754.33 g/cm³

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question

mass = 21.7 kg = 21700 g

volume = 5.78 cm³

We have

[tex]density = \frac{21700}{5.78} \\ = 3754.3252...[/tex]

We have the final answer as

3754.33 g/cm³

A sample of N2H4 has a mass of 25g. Identify the numerical quantity that is needed to convert the number of grams of N2H4 to the number of moles of N2H4. (You do not need to do the actual calculation.)

Answers

Answer:

Molecular Mass

Explanation:

It's asking for the numerical quantity. That quantity would be the Molecular Mass. Take the sample mass and divide it by the molecular mass to get the number of moles.

(14g N * 2) + (1g H *4) = 32g / mol of N2H4

To get # of moles, divide the sample mass by the molecular mass

25g / 32g = 0.78125 moles

1.35 moles Ne
0.135 moles Ne
135 moles Ne
13.5 moles Ne

Answers

Answer:

13.5 moles of Ne

Explanation:

1 mole of any gas contains  6.02 x 10²³ atoms of gas

6.02 x 10²³ atoms of neon is equal to 1 mole of neon .

8.15 x 10²⁴ atoms of neon is equal to  1 x 8.15 x 10²⁴ / 6.02 x 10²³ moles

= 8.15 x 10²⁴ / 6.02 x 10²³ mole o neon

= 13.5 moles of Ne .

How is heat transferred when you touch an ice cube?

Answers

Answer:

The heat is transferred from your hand to the ice, this is because, as we know, heat gets transferred from a hot object to a colder object.

In this case, our hand is clearly hotter than the ice cube.

Therefore, the heat is transferred from your hand to the ice cube.

use the facts that water has a higher specific heat than rock (such as Granite) to explain the differences in the temperature curves for the two cities in the graph.

Answers

Since water has a high specific heat, that results in water being able to store/require more energy in order to change it’s temperature. Since San Francisco is so close to water, that would mean that it’s temperature should vary less since water would be able to keep the temperature around the same value even if there was an increase or decrease in thermal energy.  

What physical property of the metal rods was being tested during step 4 of the procudure?

4. Measure and record how long it takes heat from the hot plate set on "high" to melt the wax ball.

A.
magnetism
B.
thermal conductivity
C.
electrical conductivity
D.
density

Answers

Answer:

B.  thermal conductivity

Explanation:

They physical property being tested during the fourth step is the thermal conductivity of the materials.

Thermal conductivity is the ability of a body to transmit heat energy from one place to another.

Since we are measuring how long it takes for heat from the hot plate to reach the wax ball, this is a typical experiment for measuring thermal conductivity. Most metals are good conductors and heat energy moves fast in them.Non-metals are poor conductors with low thermal conductivity.

What is an Atomic number?

An atomic number may be defined as the number of protons in the nucleus of an atom that significantly represents the characteristic of a chemical element and determines its specific place in the modern periodic table.

According to the modern periodic table, an element that has an atomic number of 53 is known as Iodine. Its electronic configuration is [tex]1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 4s^2, 3d^1^0, 4p^6, 5s^2, 4d^1^0, 5p^5[/tex].

Diffusion of Ammonia in an Aqueous Solution. An ammonia (A)-water (B) solution at 278 K and 4.0 mm thick is in contact at one surface with an organic liquid at this interface. The concentration of ammonia in the organic phase is held constant and is such that the equilibrium concentration of ammonia in the water at this surface is 2.0 wt 'Yo ammonia (density of aqueous solution is 991.7 kg/m3) and the concentration of ammonia in water at the other end of the film 4.0 mm away is 10 wt % (density of 961.7 kg/m3). Water and the organic are insoluble in each other. The diffusion coefficient ofNH3 in water is 1.24 x 10- 9 m 2/sCalculate the flux N_B. Explain.

How many moles of gold, a U, are in 3.60×10^-5 G of gold?

Answers

Answer:

See Below.

Explanation:

This is a conversion problem:

Using the molar mass of Gold (given in a periodic table) which is 196.97g/mol

you have

[tex](3.60*10^-5 g) *\frac{1moles}{196.97g}[/tex]

you always arrange the equation in a way to cancel whatever you don't want (grams) and leave what you do want (moles). Here grams cancel (top and bottom), so you're left with:
