Calcium carbonate can break down to form calcium oxide and carbon dioxide. The balanced chemical equation has been 3 CaCO₃ ⇒ 3 CaO + 3CO₂
What is balanced chemical equation ?The term balanced chemical equation is defined as the total number of mass of reactant is exactly equal to the total number of mass of product.
The balanced equation can be given to follow the law of conservation of mass. With equal number of atoms of all elements are present on the product and the reactant side in the reaction.
The given equation is written with addition of 3 as a coefficient to the carbon dioxide in above reaction is as follows:
CaCO₃ ⇒ CaO + 3CO₂
The number of elements of oxygen in reaction on product side has been 6 atoms for carbon dioxide and 1 oxygen atom for calcium oxide. The total oxygen on product side has been 7. The reactant has the presence of 3 oxygen atoms. So, for balancing the equation.
The reaction has been balanced with equal atoms on both the sides as follows:
3 CaCO₃ ⇒ 3 CaO + 3CO₂

1. Basaltic lava flows (those referred to as low viscosity flows) can travel 1-10 km/hr (0.6- 6 mi/hr) depending on the steepness of the slope of the land. Hawai'ian neighborhoods have been covered by lavas (or threatened to be covered by lava) that erupted from the Pu'u O'o vent. The vent was only 15 km (9.3 mi) from the town of Kalapana and 20 km (12.6 mi) from the town of Pahoa. Given the lava flow rates, how much time would civil defense officials (the people who decide if evacuations are necessary) have to evacuate a town if the lava flows were moving at 10 km/hr? (note 1 mi = 1.6 km)?
Answer:
The time will be "2 hours".
Explanation:
Around 10 km/hr, lava eruptions were travelling. The vents was just 15 km (9.3 mi) away Kalapana city as well as 20 km (12.6 mi) from Pahoa city.
So, we therefore need add the method, which would be: to taking out another time that civil defense officials just had to assess a city.
⇒ [tex]Time = \frac{Total \ distance}{Flow \ rate \ of \ lava}[/tex]
Thus, to measure the time spent throughout the community of Kalapana,
⇒ [tex]Time=\frac{15}{10}[/tex]
[tex]=1.5 \ hours[/tex]
The civil defense officers provide 1.5 hours of time each assess the city of Kalapana.
In order to measure the time spent in the towns of Pahoa,
⇒ [tex]Time = \frac{20}{10}[/tex]
[tex]=2 \ hours[/tex]
what is the theory for formation of fossil fuel plz help
A:cabon dioxide levels decreased, resulting in nitrogen fixation
B:earth cooled, changing oxygen to carbon
C:fossil fuels are the remnants of organisms that lived a long time ago and were buried, heated, and formed into hydrocarbons
D:fossil fuels arrived on earth from comets and asteroids
Answer:
The theory of the formation of fossil fuels is that fossil fuels are the remnants of organisms that lived a long time ago and were buried, heated, and formed into hydrocarbons.
Explanation:
A is not correct because the nitrogen is not a gas that is dominant in fossil fuels.
B is not correct because the oxygen can not turn to carbon in any manner.
C is correct because the consensus about the formation of fossil fuels is that after the organisms were dying out, they were getting buried (usually in the soft layers of the ocean floor), over time with the higher temperatures and pressure from below managed to change their structure and create hydrocarbons.
D is not correct because there hasn't been any evidence so far that there are fossil fuels on comets and asteroids.
Answer:
The theory of the formation of fossil fuels is that fossil fuels are the remnants of organisms that lived a long time ago and were buried, heated, and formed into hydrocarbons.

There are disagreements today over how the Indo-European language diffused from west and south Asia into Europe. Two naturally opposing theories attempt to explain this diffusion. Explain and compare the Kurgan warrior theory with Renfrew's theory in terms of geographic hearth, methods, and reasons for using the language.
Answer:
They state the languages have been formed by war and capturing of lands while other focuses on peaceful spreading of language by agriculture, population growth.
Explanation:
Renfrew's theory is called the Anatolian hypothesis and is based on the sedentary farmer theory and was developed by a British archeologist who stated the dispersal of Indo-European language. The kuren hypothesis or the steppe theory widely accepted the Indo European homeland and spreading of languages spreading through Europe, and many parts of Asia. The hypothesis speaks of the Proto Indo European during the neolithic era that spread and expanded towards Arabia around 5000 BC.Answer:
( Kurgan warrior theory) It has been stated that languages were created by war and the conquering of land.

A glaciovolcano is a volcano covered by glaciers. When it erupts, the glaciers covering it can melt. What is the most likely result of such an eruption?
Group of answer choices
a flood
an avalanche
a tsunami
an earthquake
Answer:
a flood
Explanation:
a flood – this is the right answer. As the eruption happens below the surface of the glaciers, the ice on the top melts under the erupting lava. This melted ice turns into the water, causing the flooding. These floods are called Jökulhlaups, meaning “glacial run” in the Icelandic language as it is in this country that glaciovolcano eruptions can often happen. This is the type of glacial outburst flood, and the most famous example is the eruption of Grímsvötn volcano in 1996.
an avalanche – this is not the right answer. There are glaciers and ice on the glaciovolcano, and it is snow that creates an avalanche. Also, the snow would be melted under the health.
a tsunami - this is not the right answer. The eruption of glaciovolcano can’t cause the tsunami.
an earthquake – this is not the right answer. Glaciovolcano eruption doesn’t cause an earthquake.

Which of the following best describes a country with a rate of natural increase of 0.4 ?
A Negative population growth
B Low life expectancy
C Slow population growth
D Increasing fertility rates
E Decreasing percent elderly population
Slow population growth is best describes a country with a rate of natural increase of 0.4.
Explanation:
The rate of natural increase applies to the difference within the number of live births and deaths happening in a year.
The word increase used to show the birth rate higher than the deaths.The natural increase of 0.4 can understand through a population that would grow by 0.4% in a year. That means that after one year, there will be 400 more individuals than in the previous year.Therefore, we can conclude that a country with a rate of natural increase of 0.4 indicates slow population growth.
Thus, the correct answer is "option C" (Slow population growth).

m∠POQ = 24 and m∠POR = 59,
what is m∠QOR?
Answer:
83
Explanation:
POQ+POR = QOR
24+59=83
The measure of m∠QOR given that m∠POQ = 24 and m∠POR = 59 is 25degrees.
This question bothers on lines and angles in geometry. Geometry is a branch of mathematics which deals with the measurement of lines, angles and properties of shapes.
From the question, we are given the following:
M∠POQ = 24
m∠POR = 59
Required
m∠QOR
To get the measure of m∠QOR, we will use the expression
m∠POR = m∠POQ + m∠QOR
Substitute the given values into the expression
59 = 24 + m∠QOR
m∠QOR = 59 - 24
m∠QOR = 25°
This shows that the measure of m∠QOR is 25degrees.

B The moon passes a point directly between the sun and earth
C The moon is at a full-moon phase of the lunar cycle
D The moon is in the new phase of the lunar cycle
Answer:
B The moon passes a point directly between the sun and earth
Explanation:
During solar eclipse, the moon passes a point directly between the sun and the earth thereby casting a shadow on the earth.
An eclipse is a phenomenon whereby an astronomical body obscures the path of light to another thereby casting a shadow on the other.
In solar eclipse, the moon obscures light from the sun from reaching the earth. This causes a shadow to be cast on the earth. Portions of the earth directly facing the moon becomes suddenly dark. An eclipse usually lasts for a short duration from a few seconds to some minutes.Lunar eclipse occurs when the earth comes in between the sun and the moon.
