Answer:

A. How much decay happens in each flashlight

Explanation:

In an experiment, the DEPENDENT OR RESPONDING VARIABLE is the variable that responds to changes being made to another variable called Independent variable. It is the variable that is measured by an experimenter.

In this question, an experiment was carried out to research the effect of sunlight on plastic decay. Three plastic flashlights were used for this experiment in which one was placed in a dark closet (control), and the others were placed in light at different times or intervals. However, the variable being measured or assessed is the decay of each flashlight. This means that "HOW MUCH DECAY HAPPENS IN EACH FLASHLIGHT" is the dependent variable.

Answer:

The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. ... Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.

32.Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.

33.examples to show that plastics are non corrosive in nature: Iron nails get rusted when exposed to moisture and air but plastic do not react with water and air. Plastic does not react with strong chemicals. Hence,cleansing chemicals are stored in plastic bottles and not in metal containers.

34.rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm, typically to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulfur and nitrogen oxides, which combine with atmospheric water to form acids.

Answer:

1. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained. Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed

2.  However after pouring the water from one short glass into a tall glass,  to be the same amount after being poured into any other container

3. Yes, wood have a fixed shape. Explaination: The reason is that it's solid and solids have a definite volume and shape. ... They have shapes that do not change and volumes that can be measured

4. Water is known to exist in three different states; as a solid, liquid or gas. Clouds, snow, and rain are all made of up of some form of water. A cloud is comprised of tiny water droplets and/or ice crystals, a snowflake is an aggregate of many ice crystals, and rain is just liquid water

5. Solids are sometimes formed when liquids or gases are cooled; ice is an example of a cooled liquid which has become solid. Other examples of solids include wood, metal, and rock at room temperature

6. For example, water commonly exists in three states of matter: solid (ice), liquid (water), and gas (steam)

Explanation:

1. It will adopt its container's shape. Within a liquid, particles can move around, yet the volume is maintained because of the liquid's dense packing. Particles in gaseous stuff are arranged so haphazardly that neither their shape nor their volume can be determined.

The term liquid is defined as substance which is not solid but which flows and can be poured and take a shape of container. water is an example of liquid.

2. However, the same amount of water would be poured into any other container after being transferred from one short glass to a tall glass.

3. The shape of wood is fixed. It's solid, and solids have a distinct volume and shape, which explains why. They have measurements-able volumes and unchanging forms.

4. There are three recognized states of water: solid, liquid, and gas. Snow, rain, and clouds are all composed of water in some way. A snowflake is an accumulation of several ice crystals, a cloud is made up of microscopic water droplets and/or ice crystals, and rain is just liquid water.

5. When liquids or gases are chilled, solids can occasionally form; ice is an example of a cooled liquid that has solidified. At room temperature, solids also include wood, metal, and rock.

6. As an illustration, water typically exists in three states: solid (ice), liquid (water), and gas (steam).

Answer:

the second question should be along the staircase

Answer: 3

Explanation:

3) both electrolytic cells and voltaic cells

The statement, that describes reduction occurs at the cathode is "both electrolytic cells and voltaic cells."

The gain of electrons is referred to as reduction. The species that is being oxidised is also known as the reducing agent or reductant, whereas the species that is being reduced is known as the oxidising agent or oxidant.

Reduction takes place at the cathode electrode whereas oxidation occurs at the anode in both galvanic and electrolytic cells, and electrons travel from the anode to the cathode.

Electrons must move toward the location of reduction since reduction is the addition of electrons. The negative charge is on the cathode of an electrolytic cell, while the positive charge is on the anode.

Hence, the correct answer is 3.

Answer:

[tex]\Delta _rH=-802.2kJ/mol[/tex]

Explanation:

Hello!

In this case, according to the given chemical reaction, it is possible to calculate the enthalpy change of the reaction via:

[tex]\Delta _rH=\Delta _fH_{CO_2}+2\Delta _fH_{H_2O}-\Delta _fH_{CH_4}[/tex]

Since the enthalpy of formation of oxygen is 0. Thus, given the enthalpies of formation of gaseous carbon dioxide and water, we obtain:

[tex]\Delta _rH=(-393.5kJ/mol)+2(-241.8kJ/mol)-(-74.9kJ/mol)\\\\\Delta _rH=-802.2kJ/mol[/tex]

Best regards!

The lithosphere is where all three forms of rocks form.  A physical change is a reversible change and chemical changes are irreversible. The melting of ice is a physical change and change of matter is chemical.

The lithosphere is the layer of earth where all three types of rocks such as igneous, metamorphic, and sedimentary can be found. The physical changes are those that affect physical properties and are reversible like heating and cooling.

While the chemical changes are irreversible. The physical changes lead to the change in form of the substance while chemical change leads to the rearrange of matter.

Answer:

0.0526mol

Explanation:

The chemical equation given in this equation is as follows:

Na3PO4 + Sr(NO3)2 → Sr3(PO4)2 + NaNO3

However, this equation is unbalanced as the number of atoms of each element on each side does not correlate. The balanced equation is as follows:

2Na3PO4 + 3Sr(NO3)2 → Sr3(PO4)2 + 6NaNO3

This balanced equation means that:

2 moles of Sodium Phosphate (Na3PO4) is required to react with 3 moles of Strontium Nitrate (Sr(NO3)2)

Hence, if 0.0789 moles of Strontium Nitrate are reacted, then 0.0789 × 2/3

moles of sodium phosphate will also react.

= 0.0789 × 2/3

= 0.1578/3

= 0.0526mol

Answer: D. 239 g of [tex]Br_2[/tex]

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} KBr=\frac{356g}{119g/mol}=2.99moles[/tex]

The balanced chemical reaction is:

[tex]Cl_2+2KBr\rightarrow Br_2+2KCl[/tex]  

According to stoichiometry :

2 moles of [tex]KBr[/tex] produce =  1 mole of [tex]Br_2[/tex]

Thus 2.99 moles of [tex]KBr[/tex] produce =[tex]\frac{1}{2}\times 2.99=1.495moles[/tex]  of [tex]Br_2[/tex]

Mass of [tex]Br_2=moles\times {\text {Molar mass}}=1.495moles\times 159.8g/mol=239g[/tex]

Thus 239 g of [tex]Br_2[/tex] will be produced from 356 g of KBr.
