what ionic are compounds used in our daily life?

Answer:

c- subduction zones

Explanation:

Answer/Explanation:

A geyser is hot water erupting from a vent in the earth. Geysers are somewhat rare and occur in certain parts of the earth. Underneath, there are hidden chambers that provide constant flows of water. Sometimes when the tectonic plate of the earth move, it leaves gaps in between the hot earth's inner core and the ground. The magma inside is able to heat up the water from the earth. Since hot particle tend to rise, the water explodes out of the vent with such power from the heat.

Answer: FeO is called ferrous oxide while Fe2O3 is ferric oxide

Explanation:

Ferrous oxide, commonly known as iron(II) oxide contains iron that lost 2 elections in the oxidation process. So it is able to bond with other atoms that have an extra 2 electrons to share. Ferric oxide, is commonly known as iron(III) oxide

Answer:

Hydrogen is a substance because it has mass and combined with other molecules it can make another substance such as water.

Explanation:

Answer:

33300J

Explanation:

Given parameters:

Mass of ice  = 100g

Unknown:

Amount of energy = ?

Solution:

This is a phase change process from solid to liquid. In this case, the latent heat of melting of ice is 3.33 x 10⁵ J/kg.

 So;

            H  = mL

m is the mass

L is the latent heat of melting ice

  Now, insert the parameters and solve;

            H = mL

 mass from gram to kilogram;

            100g gives 0.1kg

  H = 0.1 x 3.33 x 10⁵ = 33300J

Answer:

the light comes from the sun

Explanation:

the light from the sun reflects on the moon and the moon gets its light.

The moon is always half-lit by the light that comes from the sun except during the lunar eclipse. The light source for the moon is the sun.

The lunar phase or Moon phase can be described as the shape of the Moon's directly sunlit portion, which can be demonstrated quantitatively using areas or angles, or qualitatively utilizing the terminology of the four major phases: new moon, first quarter, full moon, last quarter.

The lunar phases gradually change over a month as the Moon's orbital positions around Earth and the position of the Earth around the Sun shift. The visible side of the Moon is sunlit, according to the position of the Moon in its orbit.

Thus, this face's sunlit part of the moon can vary from 0% to 100%. Each of the 4 major lunar phases is approximately 7.4 days, with +/− 19 hours in variation due to the elliptical shape of the orbit of the Moon.

Answer:

mass in a given volume

Explanation:

Density is the mass in a given volume or mass per unit volume of a substance.

Mass is defined by the amount of matter present in a substance.

Volume is the space occupied by a body.

Mathematically;

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

Answer:

Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides.

Explanation:

Answer:

Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides. Hence, the range (difference in water level between high and low tide) is much larger in a spring tide than in a low tide.

Answer:

Plants need energy from the sun, water from the soil, and carbon from the air to grow. Air is mostly made of nitrogen, oxygen, and carbon dioxide. So how do plants get the carbon they need to grow? They absorb carbon dioxide from the air.

Friction causes the molecules on rubbing surfaces to move faster, therefore they have more energy. This gives them a greater temperature, and they feel warmer.

The term friction is defined as the resistive force that occurs when two bodies in contact move relative to one another.

Adhesion between body surfaces, and the adhesion is the molecular force that occurs when two materials come into contact with each other are the causes of friction.

Friction is an everyday force that is generated by two surfaces when they are interacting. When these surfaces slide against each other, this interaction increases the thermal energy of the two surfaces.

Thus, Friction causes the molecules on rubbing surfaces to move faster, therefore they have more energy.

Answer:

Electrical conductivity in metals is a result of the movement of electrically charged particles. Because valence electrons are free to move, they can travel through the lattice that forms the physical structure of a metal.

Explanation:

Answer:

148 g H₂SO₄

General Formulas and Concepts:

Chemistry - Stoichiometry

Explanation:

Step 1: Define

RxN:   Ca(OH)₂ + H₂SO₄ → CaSO₄ + H₂O

Given:   3.01 moles H₂O

Step 2: Balance RxN

Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O

Step 3: Define conversions

Molar Mass of H - 1.01 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of H₂SO₄ - 2(1.01) + 32.07 + 4(16.00) = 98.09 g/mol

Step 4: Stoichiometry

[tex]3.01 \ mol \ H_2O(\frac{1 \ mol \ H_2SO_4}{2 \ mol \ H_2O} )(\frac{98.09 \ g \ H_2SO_4}{1 \ mol \ H_2SO_4} )[/tex] = 147.625 g H₂SO₄

Step 5: Check

We are given 3 sig figs. Follow sig fig rules.

147.625 g H₂SO₄ ≈ 148 g H₂SO₄

Answer:

Zirconium has 40 protons and 51 neutrons

Answer:

One object could have more particles and greater total kinetic energy

Explanation:

The higher the temperature the more the particles. So, when we have high temperature, there is more particles interacting.

Temperature can simply be defined or gotten by taking the average of of the kinetic energy of the particles in the object that is the keywords here are TAKING THE AVERAGE KINETIC ENERGY

Thermal energy is the energy that can be gotten from adding up all the total kinetic energy of the particles in the object. So, the keywords here are; ADDING UP THE TOTAL KINETIC ENERGIES.

So, when two particles of the same temperature have the different thermal energy it means that One object could have more particles and thus having greater total kinetic energy.
