K and Ca

S and Cl

K and Cl

C and O

Answers

Answer 1

Answer:

K (Potassium) and Cl (Chlorine)

Explanation:

Ionic bonds are formed with metals and nonmetals

Covalent bonds are formed only with nonmetals

Calcium and potassium are both metals

Sulfur and Chlorine are both nonmetals so they don't form ionic bonds

Carbon and Oxygen are both nonmetals so they don't form ionic bonds

how many atoms of mercury are in 50.15 g of mercury?

Answers

Answer:

please mark brainliest

Explanation:

The correct answer to this question is 0.2500 mol

Formula to calculate moles:

Moles = mass ÷ molar mass (n=m/M)

Mass = 50.15g

Atomic mass: 200.59 amu

Moles = 50.15g/200.59

= 0.2500 mol.

10. Would it be possible for an earthquake at this same location to be felt where you live? Why or why not ?

Answers

Answer:

yes if big  no if weak

Explanation:

According to new research, a large earthquake can not only cause other quakes, but also large ones on the opposite side of the Earth.

What is an earthquake and how it is caused?

An earthquake is a sudden movement of rock materials beneath the earth's surface that causes a weak to violent shaking of the ground. The earthquakes are caused by tectonic plate boundaries.

Every day, earthquakes occur all over the world, along both tectonic plate edges and interiors. Earthquakes happen along faults, which are fractures in the rock that allow the blocks to move relative to one another.

Earthquakes are typically caused by underground rock suddenly breaking and rapid movement along a fault. The seismic waves that cause the ground to shake are caused by this sudden release of energy.

A large earthquake can not only cause other quakes, but also large ones on the opposite side of the Earth, according to new research.

Thus, it is possible for an earthquake at this same location to be basically felt where you live.

Find the mass in kilograms of the liquid air that is required to produce 600L of oxygen. In normal condition, 1L of liquid air has 1.3g​

Answers

Explanation:

1L is 1.3 g so 600L is 780 g

1kg= 1000g so

780 g = 0.78kg

I GUESS

Mass in kilograms of liquid air required = 0.78 kg

Given that

1 Litre of liquid air contains 1.3 grams of oxygen ( air )

Determine the amount of liquid air in Kg

volume of air given = 600 L

mass of liquid air required = x

1 litre = 1.3 grams

600 L =  x

∴ x ( mass of liquid air ) = 1.3 * 600

                                       = 780 g  = 0.78 kg

Hence we can conclude that Mass in kilograms of liquid air required = 0.78 kg

Which two elements have more protons per atom than phosphorus?​

Answers

Answer:

nitrogen have more protons per atom than phosphorus

Oxygen and fluorine are the two elements that have more protons per atom than the element phosphorus.

What is phosphorus?

Phosphorus (P), a nonmetallic chemical element of something like the nitrogen group (Group 15 [Va] of the periodic table), is a colorless, semitransparent, soft, sticky solid that glows in the dark at room temperature.

Hennig Brand, a German businessman with an interest in alchemy, appears to have discovered phosphorus around 1669. Brand left 50 buckets of pee alone till they putrified and "produced worms." He then reduced the urine to a paste and burned it with sand to extract elemental phosphorus first from combination.  Oxygen and fluorine are the two elements that have more protons per atom than phosphorus.

Therefore, oxygen and fluorine are the two elements that have more protons per atom than phosphorus.

atomic emission spectrum are true? Select all that apply. (3 are correct)

Answers

The emission spectrum of an atom consists of limited lines that are unique to a given element.

According to the Bohr model of the atom, energy is absorbed or emitted when an atom moves from one energy level to another. Since energy is quantized, the spectrum of atoms often consists of single lines.

Hence, the true statement about atomic spectrum is that; "the light that an element emits is made up of a limited number of narrow lines that produce a unique pattern or atomic emissions spectrum for that element."

What are non-renewable energy sources?

Non-renewable energy sources are sources of energy that come from finite resources that cannot be replenished on a human timescale. They are called non-renewable because their reserves are being depleted faster than they can be replenished. These energy sources include:

Fossil fuels: Coal, oil, and natural gas are the three main types of fossil fuels. They are formed over millions of years from the remains of plants and animals that lived long ago. Fossil fuels are currently the most widely used sources of energy for electricity generation, transportation, and industrial processes.

Nuclear energy: Nuclear energy is produced through the process of nuclear fission, which involves splitting atoms of uranium or plutonium to release energy. Nuclear power plants generate electricity using this process.

Non-renewable energy sources are a major contributor to greenhouse gas emissions, which contribute to climate change. As a result, there is a growing need to transition to renewable energy sources that are sustainable and have a lower environmental impact.
