Answer:
Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood leaves the heart through the aortic valve, into the aorta and to the body. This pattern is repeated, causing blood to flow continuously to the heart, lungs and body.
Explanation:
also, this means D
-emma :)
The correct path of blood through the heart and lungs is right atrium, right ventricle, lungs, left atrium, left ventricle.
What is blood circulation?The circulatory system (cardiovascular system) transports oxygen-rich blood from the heart to the lungs. The heart then pumps oxygenated blood throughout the body via arteries.
By following the below path blood will circulate:
From the right atrium of heart blood comes to the right ventricle.From the right ventricle to the lungs.From lungs goes to the left atrium and then to the left ventricle.Hence correct sequence is right atrium, right ventricle, lungs, left atrium, left ventricle.

What is most likely to occur during a chemical reaction?
a Molecules of the original substance are lost. b New atoms are created. c The original substance maintains its properties. d Mass is conserved.
During a chemical reaction, the most likely occurring is mass conservation. According to law of conservation of mass, total mass in a reaction is conserved.
What is law of conservation of mass?According to the law of conservation of mass, the total mass in a chemical reaction or in a physical change is conserved. Simply, mass is neither created nor destroyed.
When a chemical reaction takes place, no new atoms are created and the properties of the reactant species cannot be maintained after reaction.
Molecules of any reactant is not lost during a reaction. The total mass in the reactant side of a balanced reaction will be equal to the total mass in product side.
Therefore, the mass conservation is likely to occur during a chemical reaction. Thus, option d is correct.

Answer:
conduction is the transfer of heat between two objects that are next to each other and in direct physical contact, or touching . It is caused by a temperature difference between the objects. Conduction is one way that heat is transferred from Earth's surface to air. In nature, heat always moves from a warmer object to a cooler object. When air molecules touch the warm ground or water on the surface, heat is conducted from the ground or water to the air molecules, heating them up.

What happens to the atoms that make up hydrogen fuel as it burns?
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

Nicole has 2 glasses on the counter: one of water and one of sugar-water. She is baking a cake and needs to use the sugar-water for the glaze. Both glasses look identical, but one contains a mixture and the other contains a compound.
Is sugar-water a mixture or a compound? Define mixtures and compounds, and explain how, without tasting it, Nicole can test to make sure she is using the sugar-water in the glaze.
Answer:
sugar-water is a mixture not a compound.(homogeneous mixture.)
Explanation:
Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.
The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)

Answer: The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. Therefore, a high value of specific heat would mean that more heat is needed in order for the temperature to increase. The correct answer would be water since it has the highest specific heat of the choices given.

Describe how a pure sample of copper ( II ) nitrate crystals can be prepared using recycled copper wire
Explanation:
Copper(II) nitrate describes any member of the family of inorganic compounds with the formula Cu(NO3)2(H2O)x. The hydrates are blue solids. Anhydrous copper nitrate forms blue-green crystals and sublimes in a vacuum at 150-200 °C.[5] Common hydrates are the hemipentahydrate and trihydrate.
Copper ( II ) nitrate crystals can be prepared by reacting recycled copper wire with nitric acid so that chemical change takes place.The reaction is Cu + HNO₃\(\rightarrow\)Cu(NO₃)₂ +H₂O.
What is a chemical change?Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.
There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical changes:
1) inorganic changes
2)organic changes
3) biochemical changes
During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.
