Hot water deep within Earth can _________________________ minerals and transport them someplace else.
Answers
Hot-Water Solutions Groundwater works its way down and is heated by magma, and then reacts with minerals to form a hot liquid solution. H. Dissolved metals and other elements crystallize out of the hot fluid to form new minerals, such as gold, copper, sulfur, pyrite, and galena.
Answer:
What happens to hot water beneath the Earth as it moves up through fractured rock?
Circulating groundwater that comes into contact with the cooling magma is heated and rises to the surface along rock fractures to form either a thermal spring, figmarole, or geyser.

Answers
Answer:
Mark has a speed of 6 MPS (Miles Per Hour)
Explanation:
It took mark 2 hours to ride his bike to his grandma's house, which was 12 miles away. I divided 2 by 12 and got 6. Remember this: mph = miles away ÷ time.
So 12/2 So he would be going 6mph

♨ The word ' acid ' is derived from the Latin word ' acidus ' which means sour. An acid is defined as the substance which gives hydrogen ions or protons ( H+ ) when dissolved in water. For example :

☃ Physical properties :
Acids have a sour taste. But some acids like steric acid, boric acid , salisylic acid do not have a sour taste. Laboratory acids are more corrosive , so they are dangerous to taste.Acid turn blue colour of litmus paper into red and light yellow methyl orange into red. They make phenolphthalein colourless.☂ Chemical properties :
Acids have a high dissolving power and dissolve many substances. Some metals like zinc and magnesium react with acids like dilute sulphuric acid and dilute hydrochloric acid to produce salt and hydrogen gas.Acid react with base to give salt and water.Acid gives H+ ions when dissolved in water.Acid react with metallic carbonates to produce carbon dioxide.☼ Hope I helped! ♡

Answers
Answer:Melting.
Freezing.
Evaporation.
Condensation.
Sublimation.
Explanation:
Answer: Examples for the five transformations previously given.
For the first four, we encounter common examples in everyday life, all to do with water:
Freezing - liquid to solid, e.g. water to ice, e.g. making ice cubes.
Melting - solid to liquid, e.g. ice to liquid water, melting ice cubes or snow flakes.
Condensation - gas to liquid, e.g. water vapor (gas) to liquid - water vapor in air (humidity) condenses to form liquid droplets on the outside of a cold beverage glass on a hot humid day; or cloud formation in the atmosphere.
Evaporation - liquid to gas, e.g. liquid water on clothes evaporates as clothes dry on clothesline or in dryer
While water can sublime under certain conditions of temperature and pressure, it is less evident in everyday life. Carbon dioxide however is a more common example.
Sublimation - solid to gas, e.g. "dry ice" disappearing. The visible smoke associated with dry ice is most likely just condensing water vapor in the air as the solid carbon dioxide cools the air.

how do photoynthesis and cellular respiration work together to make ecosystems function?
Answers
Answer:
Photosynthesis and cellular respiration are connected through an important relationship. This relationship enables life to survive as we know it. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis:
Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O
Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O2

Answers
Answer:
A. They cycle elements through the biotic and abiotic components of an ecosystem.
Explanation:
Chemical elements such as nitrogen, carbon, phosphorus etc. moves between the living and non-living parts of an ecosystem in the biosphere. The cycle of these elements between these counterparts (abiotic and biotic) is referred to as the BIOGEOCHEMICAL CYCLE.
Firstly, the biotic components of an ecosystem refers to the living organisms such as plants, animals, microbes etc while the abiotic components are the non-living parts such as soil, water etc. Therefore, according to the description given in the options, option A describes what a BIOGEOCHEMICAL CYCLE best.

Answers
A student predicts that a solution of ethanol (C2H5OH) and water will have a lower density at room temperature than that of pure water. By taking moisture the student can test this prediction.
What are the properties of ethanol ?Ethanol is a natural plant fermented by-product which can also be produced by the process of hydration of ethylene.
It is an important industrial reagent, can be used as a solvent, for the synthesis of solvent, organic chemicals and some additive to automotive gasoline.
Its chemical formula is C2H6O, two carbon atoms and one oxygen atom where as the structural formula is C2H5OH indicating that the two-carbon chain has a hydroxyl group.
Ethanol is always a liquid at room temperature and has the melting point of 156K and a boiling point of 351 K.
It is used in making many medicines like cough syrups, tonics, any proportion of ethanol is soluble in water.
Direct consumption of even a small quantity of pure ethanol is lethal to body.

How are the groups organized in the periodic table? What do all the elements in a group have in common?
Answers
Answer:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.
Explanation:
All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
The groups in periodic table are vertical columns in which elements with similar properties and same number of valence electrons are classified together.
What are groups in periodic table ?In periodic table, all elements are classified into different periods and groups. The vertical columns in the table is called groups and the horizontal rows are called periods.
The elements in a group have same number of valence electrons and similar chemical and physical properties. For example lithium and sodium are first group elements and they show similarity in properties.
There are 18 groups and 7 periods in periodic table. The first two groups are pure metals. Groups from 3-12 are called transition metals. 13 to 18 group elements are nonmetals.

Do you think a moving skateboard has energy? Why or why not?
PLEASEEEEEE HURRY
Answers
Answer:
"Yes," a moving skateboard has energy.
When the skater seems to be in motion or throughout a movement, the potential energy converts itself into the kinetic form of energy, and then it becomes potential energy again.
Furthermore, somewhere after every movement, the same skateboarder was around a similar height, — in other words thus every time it is equally powerful.
