Answer:

Remotely operated vehicles, or ROVs, allow us to explore the ocean without actually being in the ocean. ... Additional equipment, such as a manipulator or cutting arm, water samplers, and instruments that measure parameters like water clarity and temperature, may also be added to vehicles to allow for sample collection.

Explanation:

The time taken by the car driving at 10m/s to move 200m is 20 seconds. The speed of car is 10m/s. Thus option C is correct.

Speed is defined as a measurement of the length of time it takes for an object to travel a certain distance.

The SI unit of speed is m/s, and speed is defined as the ratio of distance to time.

A change in speed is an example of acceleration because it is a change in velocity. Acceleration could be for positive or negative. Deceleration is another name for negative acceleration.

There are four types of speed.

Speed can be expressed as

Speed = Distance / Time

Given, Distance = 200 m

           Time = 10 m/s

Speed = 200m / 10m/s

           = 20 seconds

Thus, the time taken by the car driving at 10m/s to move 200m is 20 seconds. The speed of car is 10m/s. Thus option C is correct.

Chemical contamination is likely to occur when cleaning products are not stored properly.

Chemical contamination refers to the introduction of harmful chemicals into food, water or the environment. These chemical substances may come in contact with food and water in many ways.

The most common sources of chemical contamination are chemical substances that are not properly stored.

Hence, chemical contamination is likely to occur when cleaning products are not stored properly.

The final pressure of the gas mixtures is 72.48 atm.

The given parameters;

The number of moles of the gases is calculated as follows;

[tex]number \ of \ moles \ of \ oxygen = \frac{88}{16} = 5.5 \ moles\\[/tex]

[tex]number \ of \ moles \ of \ argon = \frac{33}{40} = 0.825 \ moles\\[/tex]

The total number of moles of the gas mixture;

= 5.5 + 0.825

= 6.325 moles

The final pressure of the mixture is calculated as follows;

PV = nRT

[tex]P = \frac{nRT}{V} \\\\P = \frac{6.325\ mol \times (0.0821 \ L.atm/mo.K) \times (62+273)}{2.4 \ L} \\\\P = 72.48 \ atm[/tex]

Thus, the final pressure of the gas mixtures is 72.48 atm.

Answer:

It is melting chocolate and freezing water.

Explanation:

If your melting melting chocolate it would turn into a liquid and if you freeze

water then you are turning liquid to a solid.

Melting chocolate and freezing water are the examples of phase change.

A phase change is a change in the states of matter. For example, a solid may become a liquid. This phase change is called melting. When a solid changes into a gas, it is called sublimation.

A phase transition is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter: solid, liquid, and gas.

There are eight thermal processes through which matter can attain phase change. They are melting, freezing, evaporation, condensation, sublimation, deposition, ionization, and recombination.

2Ca +O2 ----------> 2CaO ( Balanced Reaction)

The balanced chemical equation for the standard formation reaction of solid calcium oxide (CaO) is

Ca + O2 --> CaO2

A balanced chemical equation is an equation in which the the number of atoms of each elements on both the reactant and products sides are equal.

Calcium oxide is an alkaline which is solid at room temperature and is formed by the reaction of one atom of calcium and two atoms of oxygen.

Therefore, the balanced equation of formation reaction of solid calcium oxide (CaO) is Ca + O2 --> CaO2.

Taking into accoun the STP conditions and the ideal gas law, the correct answer is option e. 63 grams of O₂ are present in 44.1 L of O2 at STP.

First of all, the STP conditions refer to the standard temperature and pressure, where the values ​​used are: pressure at 1 atmosphere and temperature at 0°C. These values ​​are reference values ​​for gases.

On the other side, the pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:  

P×V = n×R×T

where:

Then, in this case:

Replacing in the expression for the ideal gas law:

1 atm× 44.1 L= n× 0.082 [tex]\frac{atmL}{molK}[/tex]× 273 K

Solving:

[tex]n=\frac{1 atm x44.1 L}{0.082\frac{atmL}{molK}x273K}[/tex]

n=1.97 moles

Being the molar mass of O₂, that is, the mass of one mole of the compound, 32 g/mole, the amount of mass that 1.97 moles contains can be calculated as:

[tex]1.97 molesx\frac{32 g}{1 mole}[/tex]= 63.04 g ≈ 63 g

Finally, the correct answer is option e. 63 grams of O₂ are present in 44.1 L of O2 at STP.

Atomic Particles

Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

Explanation:

Not only did outermost electron determine the valence electron, but also periodic table. whatever group they fall into in periodic table each valence electrons present in a particular atom e.g K and Ca belong to group 1 and 2 respectively and k has 1 and Ca have 2 in each outermost electron

In the reaction between Fe₂S₃(s) and HBr(aq), the sum of the coefficients for all reactants and products is 12.

If the reaction occurs between Fe₂S₃(s) and HBr(aq) and the equation is properly balanced with the smallest whole-number coefficients, what is the sum of the coefficients for all reactants and products?

Let's consider the unbalanced equation for the reaction between Fe₂S₃(s) and HBr(aq). This is a double displacement reaction.

Fe₂S₃(s) + HBr(aq) ⇒ FeBr₃(aq) + H₂S(g)

We will balance it using the trial and error method.

First, we will balance Fe atoms by multiplying FeBr₃ by 2.

Fe₂S₃(s) + HBr(aq) ⇒ 2 FeBr₃(aq) + H₂S(g)

Then, we will balance S atoms by multiplying H₂S by 3.

Fe₂S₃(s) + HBr(aq) ⇒ 2 FeBr₃(aq) + 3 H₂S(g)

Finally, we will get the balanced equation by multiplying HBr by 6.

Fe₂S₃(s) + 6 HBr(aq) ⇒ 2 FeBr₃(aq) + 3 H₂S(g)

The sum of the coefficients for all reactants and products is:

[tex]1 + 6 + 2 +3 = 12[/tex]

In the reaction between Fe₂S₃(s) and HBr(aq), the sum of the coefficients for all reactants and products is 12.
