the particles in water have less mobility than the particles in oxygen. Which statement best explains this observation? Water is always colder than oxygen. Water has a lower density than oxygen. Water particles have a greater kinetic energy. Water particles have strong intermolecular forces.

Answers

Answer 1

Answer:

Water particles have strong intermolecular forces.

Explanation:

Water molecules are affected by attraction and repulsion and that causes the water to have strong forces and intermolecular strength to be strong.

What are intramolecular forces?

Intramolecular forces are the forces that keep atoms together inside a molecule. Intermolecular forces are forces that exist among molecules. determine intermolecular appeal between H-Cl molecules and intramolecular attraction within H-Cl molecules.

What is a chemical symbol?

Chemical symbols are acronyms for chemical elements, functional groups, and chemical substances that are used in chemistry.

Chemical element symbols are typically composed of one or two letters from the Latin alphabet, with the first letter capitalized.

A chemical symbol, also known as an element symbol, is a letter or a combination of letters that represents a chemical element.

Because it is shorter and easier to write, the chemical symbol for an element is used when writing the chemical formula for a molecule or when writing a chemical equation.

Carbon dioxide (CO2), ammonia (NH3), and water are the three chemical compounds encountered in daily life (H2O).

Thus, these are some of the examples of chemical compounds.

summerize in your own words Continental crust is much thicker than oceanic crust (averages between 20 to 25 miles thick), but is actually slightly less dense than oceanic crust. The main type of rock on continents is called granite. So if these two types of crust were to collide into each other, what do you think would happen to the oceanic crust? As a whole, notice that the crust is lighter than the mantle. It is sometimes said that the crust "floats" on the mantle like an iceberg in water and that is not too far from the truth and is called isostacy. Finally, the crust is the coldest, most rigid, and brittle layer with lots of folds and fractures.Recall that oceanic crust is denser than continental rock like granite. Thus when two tectonic plates collide, the denser oceanic crust will subduct underneath the lighter continental crust. If the subducting rock becomes stuck, vast amounts of energy builds up. But once the pressure and energy is too great, the rock will rupture creating powerful earthquakes. As the subducted material sinks further, it will begin to melt under great heat and pressure, becoming less dense as it melts, and rise up as magma to form dangerous composite volcanoes. Mountain ranges created by oceanic-to-continental convergence are the Andes mountains in South America, the Cascades in the western United States, and the Ring of Fire in the Pacific Ocean.

A) Al with 13 neutrons
B) Mg with 14 neutrons
C) Fe with 26 neutrons
D) Ti with 26 neutrons

Answers

Answer:

The answer is B

The correct answer is option B: Mg with 14 neutrons

The mass spectrum shows the charge to mass ratio of atoms. I can be used to sort the isotopes of an element.

Isotopy is a phenomenon in which atoms of the same element have the same atomic number but different mass numbers.

The mass spectrum of atoms separates atoms on the basis of charge to mass ratio of the isotopes.

The isotopes of magnesium are;  24Mg atom which has 12 neutrons 25Mg which has 13 neutrons, and  26Mg which has 14 neutrons.

Hence, the peak at 26amu represents 26Mg which has 14 neutrons.

A certain ore is 20.7% nickel by mass. How many kilograms of this ore would you need to dig up to have 70.0 g of nickel?

Answers

Answer:

0.3382 kg

Explanation:

From the illustration:

100g of the ore would contain 20.7 g of nickel by mass. In order to obtain 70.0 g of nickel, the amount of the ore needed would be:

          100 x 70.0/20.7 = 338.16 g

According to conversion units:

1 g = 0.001 kg

Hence,

338.16 g = 338.16 x 0.001 = 0.3382 kg

Therefore, 0.3382 kg of the ore would be required in order to obtain 70.0 g of nickel.

Amount of core in Kilogram is 0.338 kg (Approx.)

Given that;

Percentage in every ore = 20.7%

Amount of nickel = 70 gram

Find:

Amount of core in Kilogram

Computation:

Amount of core in Kilogram = Amount of nickel / Percentage in every ore

Amount of core in Kilogram = 70 / 20.7%

Amount of core in Kilogram = 70 / 0.207

Amount of core in Kilogram = 338.16 gram

Amount of core in Kilogram = 0.338 kg (Approx.)

Let the volume  of solute  be =  y  ml

the volume  of  solution =  400 ml

convert 70%  to fraction = 70/100

by  substituting  the value  in the equation

= y  ml/  400 ml =  70/100
