balance the following chemical equation making sure to apply the principle of the law of conservation of mass
Answer:
2Zn+ 4HCl=2ZnCl2 +2H2
CH4+2O2=CO2+2H2O
Fe + 3NaBr=FeBr3+3Na
The balanced chemical equations are given below:
[tex]Zn + 2HCl[/tex] → [tex]ZnCl_2[/tex] + H2. [tex]CH_4 + 2O_2[/tex] → [tex]CO_2 + 2H_2O[/tex]. [tex]Fe + 3NaBr[/tex] → [tex]FeBr_3 + 3Na[/tex]. What do you mean by Chemical equation?Chemical equations may be defined as an illustration of a chemical reaction by using symbols and the amount of substance used in the reactant to form a desirable product.
In the first reaction, two atoms of hydrogen are there on the product side while only one is there is the reactant side, so to balance them, you put 2HCl, the reaction is balanced now.
In the second reaction, four atoms of hydrogen are there on the reactant side while only two are on the product side, so to balance them you put 2H2O on the product side, now balance the oxygen atom and put 2O2 on the reactant side. The reaction is balanced now.
In the third reaction, bromine has three atoms on the product side, to balance them you need to put 3NaBr on the reactant side, now to balance sodium atoms put 3Na on the product side. The reaction is now balanced now.
The principle of the law of conservation of mass states that mass is neither be created nor destroyed in chemical reactions.
Therefore, the balanced chemical reactions are described above.

Answer: Read below!
Explanation:
Cells: the smallest structural and functional unit of an organism.
Cell Processes: any process that is carried out at the cellular level, but not necessarily restricted to a single cell.
Photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
Respiration: a process in living organisms involving the production of energy.
Genetics: he study of heredity and the variation of inherited characteristics.
Evolution: the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
Ecology: the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
Human Body: the physical substance of the human organism, composed of living cells and extracellular materials and organized into tissues, organs, and systems.

The most ATP is generated during:
light-dependent and Calvin Cycle reactions
glycolysis and fermentation
Krebs cycle and electron transport chain
light-dependent reactions and fermentation
I need help
Answer:
Krebs cycle and electron transport chain
Explanation:
Energy in form of ATP, which is needed by all living cells, is produced from a cell process called CELLULAR RESPIRATION. Cellular respiration is composed of three other processes depending on the availability of oxygen: glycolysis, Krebs cycle and electron transport chain.
Overall, glycolysis which takes place in the cytoplasm produces 2 molecules of ATP while the Krebs cycle and electron transport chain (ETC) produces a collective accumulation of 34 ATP molecules.
How do heart rate and cellular respiration relate to each other?
Answer:
Several changes take place in the body to enable this: the breathing rate and volume of each breath increases to bring more oxygen into the body and remove the carbon dioxide produced. the heart rate increases, to supply the muscles with extra oxygen and remove the carbon dioxide produced.

Humans benefit from natural resources every day. For example, right now you're using a computer or similar device
to read this question. Can you name any natural resources that were likely used to build this device? What natural
resources are you using by operating it?
Answer:
copper
Explanation:
is a mineral used to make electrical conductors because of its durability.
human beings are also natural resources,so by me operating this computer,am utilizing myself as a natural resource.
The laptop is a device which is generally used. It is composed of electrical conductors which contains metals such as copper. Copper is a natural resource.
What are Natural resources?Natural resources are those resources which are drawn from the nature and are used with few modifications. This includes the sources of valued characteristics such as those for commercial and industrial use, aesthetic value, scientific interest, and cultural value.
Copper is a highly recyclable, non-renewable natural resource. It is present in a finite amount and cannot be regenerated once used fully. Copper is a soft and malleable metal which is used in the electrical wires and cables for its good conductivity, in the industrial machinery and construction materials for its durability, machinability, and corrosion resistance, and also the ability to be cast with high precision.

What makes human beings different from other animals?
Answer:
There are many characteristics in humans that can define us to be different than other animals. For example, our body. Humans are generally more flexible than animals. One can bend in different ways while other animals are minimalistic in comparison to our flexibility. Another example is our life span. Humans have more life span than most animals but not all. Many animals have lesser life span from days, months to few years with exception of tortoise, elephants which have more than ourselves. Like I said in the beginning, there are many more traits that differ us from other animals.

how is sound recorded
Answer:
Sound is made up of waves in the form of vibrations in the air. Or you can use the signal to record the sound on magnetic tape. This works by a similar process of moving a magnet, but that magnet causes a magnetic tape to gain magnetization in patterns that represent the sound.
In a digital recording system, sound is stored and manipulated as a stream of discrete numbers, each number representing the air pressure at a particular time. The numbers are generated by a microphone connected to a circuit called an ANALOG TO DIGITAL CONVERTER, or ADC.
hope this helps
have a good day :)
Explanation:
Answer:
sound is made up of waves in the form of vibrations in the air, and can be detected by the human ear. Using magnets analoque technology takes sound waves and turns them into electrical pulses. When a metal conductor is moved inside the magnetic field an electric current is produced in that wire.

‘Plant and animals are interdependent on each other’, Why do they depend on each other. Write three points to justify your answer.
Answer:
Animals are consumers and they all depend on plants for survival. Some eat plants directly, while others eat animals that eat the plants. In turn, some plants depend on animals to help spread their seed. Decomposing animal carcasses can also provide nutrients for plants to grow.
Plants and animals depend upon each other as mutual interdependence is must for their survival. Plants provide shelter for animals and they make oxygen for the animals to live. When animals die they decompose and become natural fertilizer plants. Plants depend on animals for nutrients, pollination and seed dispersal
