Can a bearded dragons eat a Hammerhead worm

Answer:

0.08kg

Explanation:

Given parameters:

Temperature of water  = 100°C

Quantity of heat released = 180414.08J

Unknown:

Quantity of water condensed  = ?

Solution:

This is simple phase change process without any attendant change in temperature.

To solve this problem, use the formula below;

             H  = mL

H is the heat released

m is mass

L is the latent heat of condensation of water  = 2260 kJ/kg

 Insert the parameters and solve;

       180,414.08 = m x  22.6 x 10⁵ J/kg

         m  = [tex]\frac{180414.08}{2260000}[/tex]   = 0.08kg

Answer:

Boiling point.

Heat is required to break the intermolecular forces of attraction between the particles. The role of coolant is to lowers the freezing point of water, and to increase the boiling point of water.

Phase transition is a process in which transition takes place from one state to another of a medium on changing temperature or pressure. Phase transition is a physical process as there is no breaking of old bond and forming of new bonds takes place.

Coolant is added to car radiators to keep the water from becoming a gas and evaporating when the car gets hot. The role of coolant is to lowers the freezing point of water, and to increase the boiling point of water.

Therefore, the role of coolant is to lowers the freezing point of water, and to increase the boiling point of water.

[tex]T_{eq}=27.97\°C[/tex]

Explanation:

Hello.

In this case, for equilibrium temperature problems, it is said that the heat balance allows us to notice how the hot substance heats up the cold substance until they reach the equilibrium temperature which is a temperature that remains constant upon time. Thus, since here the hot substance is the nickel and water gains that released heat by the nickel we can write:

[tex]Q_{Zn}=-Q_{water}[/tex]

Which can be written in terms of temperatures, masses and specific heats:

[tex]m_{Zn}C_{Zn}(T_{eq}-T_{Zn})=-m_{water}C_{water}(T_{eq}-T_{water})[/tex]

Thus, solving for the equilibrium temperature we write:

[tex]T_{eq}=\frac{m_{Zn}C_{Zn}T_{Zn}+m_{water}C_{water}T_{water}}{m_{Zn}C_{Zn}+m_{water}C_{water}}[/tex]

Now, plugging in the known data, considering the mass of water 64.00-4.00=60.00 g and its initial temperature, 25.00°C, we obtain:

[tex]T_{eq}=\frac{34.10g*0.444\frac{J}{g\°C}* 77.17\°C+60.0g*4.184\frac{J}{g\°C}*25.00\°C}{34.10g*0.444\frac{J}{g\°C}+60.0g*4.184\frac{J}{g\°C}}\\\\T_{eq}=27.97\°C[/tex]

The final temperature of water is required.

The final temperature of water is [tex]27.97^{\circ}\text{C}[/tex].

T = Equilibrium temperature

[tex]T_n[/tex] = Temperature of nickel = [tex](77.17^{\circ}\text{C}+273.15)\ \text{K}[/tex]

[tex]T_w[/tex] = Temperature of water = [tex](25^{\circ}\text{C}+273.15)\ \text{K}[/tex]

[tex]c_n[/tex] = Specific heat of nickel = [tex]0.444\ \text{J/g}^{\circ}\text{C}[/tex]

[tex]c_w[/tex] = Specific heat of water = [tex]4.184\ \text{J/g}^{\circ}\text{C}[/tex]

[tex]m_n[/tex] = Mass of nickel = 34.1 g

[tex]m_w[/tex] = Mass of water = 60 g

The heat balance of the system is given by

[tex]m_wc_w(T-T_w)=m_nc_n(T_n-T)\\\Rightarrow m_wc_wT-m_wc_wT_w=m_nc_nT_n-m_nc_nT\\\Rightarrow T=\dfrac{m_nc_nT_n+m_wc_wT_w}{m_wc_w+m_nc_n}\\\Rightarrow  T=\dfrac{34.1\times 0.444\times 350.32+60\times 4.184\times 298.15}{60\times 4.184+34.1\times 0.444}\\\Rightarrow T=301.12\ \text{K}=301.12-273.15\\\Rightarrow T=27.97^{\circ}\text{C}[/tex]

Answer:

c. closer together and lower in energy than those in a gas.

Explanation:

In the different states of matter, the arrangement of particles and the kinectic energy that exists in the state of matter varies depending on which state the matter is in.

The particles of Solid are denser and closer than that of liquid. In solid state, the force of attraction between the particles are greater than the kinectic energy of the particles in a solid matter. Therefore, the particles in solid matter are closer together than those in liquid and gas. And also, the energy is lower in Solid matter than those in liquid and gas.

Liquid on the other hand, has denser particles that are closer together than those in gas. Also, liquid particles has lower energy than those in gas.

Particles in gas are more freer and farther apart from each other than the particle sin solid and gas. Also, particles in gas is greater than those in liquid and solid.

Therefore, the likely arrangement of particles in a liquid is that they are:

c. closer together and lower in energy than those in a gas.

KE at 30°F=0.942 KE at 60°F

The average kinetic energy value is only affected by temperature changes. The higher the temperature, the average kinetic energy of the molecule increases  

This molecule is very small when compared to the distance between molecules, so the volume of gas contains mostly empty space  

Gas particles move randomly (both speed and direction , as vector)  

Average velocities of gases can be expressed as root-mean-square averages. (V rms)  

[tex]\large{\boxed{\bold{v_{rms}=\sqrt{\frac{3RT}{Mm} } }}[/tex]

R = gas constant, T = temperature, Mm = molar mass of the gas particles

Kinetic energy :

[tex]\tt KE=\dfrac{1}{2}mv^2[/tex]

The temperature outside is 60°F

Convert to Celcius and Kelvin

°C = 5/9 (°F-32)

[tex]\tt ^OC=\dfrac{5}{9}(60-32)=15.56[/tex]

Answer:

Heat energy is transferred to cooler objects to reduce the temperature of those objects.

Explanation:

The fourth option is not correct.

A correct way of writing it would be : " Heat energy is transferred from cooler objects to reduce the temperature of those objects.". When an object loses heat energy, its temperature reduces. Conversely, when an object receives heat energy, its temperature increases.

Answer:

No. All four hybrids are equivalent and the angles between them are all the same, so we can use any of the two to hold the nonbonding pairs.

Explanation:

Orbital hybridization has been the combination of the atomic orbitals for the formation of a new hybrid. No, it does not matter which orbitals are used to hold the nonbonding electron pairs.

Hybrid orbitals are said to be formed by the mixing of the atomic orbitals with different energy and geometrical shape that allows the understanding of the atomic bonding and molecular geometry of the compounds.

It includes sp, sp², sp³, sp³d, and sp³d² which have various arrangements, including linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. The hybrid orbitals are formed by the combination and overlapping of the s and p orbital.

It does not matter which sp³ orbital holds the two non-bonding electron pairs as all four hybrids have been known to have equivalent angles between them so it will not matter which hybrid has the non-bonded electrons in them.

Therefore, it will not matter which two sp³ hybrid holds the electron pairs that are not involved in bonding.

We are given:

Mass of the mixture = 1.5 grams

Number of Moles of NaHCO₃ = 0.01 mole

Mass of 0.01 moles of NaHCO₃:

Mass = number of moles * Molar mass

Mass = 0.01 * 84

Mass = 0.84 grams

Mass% of Na in NaHCO₃:

Molar mass of NaHCO₃ = 84 grams/mol

Molar mass of Na = 23 grams / mol

Mass% = (Molar mass of Na / Molar mass of NaHCO₃) * 100

Mass% = (23/84) * 100

Mass% = 27%

Mass of Na in 0.01 moles:

Since the Mass% of Na is 27% and the total mass is 0.84 grams

So, we can say that 27% of 0.84 is the mass of Na

Mass of Na = 0.84 * 0.27

Mass of Na = 0.23 grams

Mass% of Na in the mixture:

Total mass of the mixture = 1.5 grams

Mass of Na in the mixture = 0.23 grams

Mass% of of Na in the Mixture = (Mass of Na / Mass of Mixture) * 100

Mass% of Na = (0.23 / 1.5) * 100

Mass% of Na = 15.3%

Therefore, we have 15.3% Na in the given mixture by mass

P₂ = 112.17 KPa

Explanation:

Given data:

Initial pressure = 116 KPa

Initial temperature = 303 K

Final temperature = 293 L

Final pressure = ?

Volume=  constant

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

116 KPa / 303 K = P₂/293 K

P₂ = 116 KPa × 293 K  / 303 K

P₂ = 33988 KPa. K / 303 K

P₂ = 112.17 KPa

Average atomic mass = 20.2 amu

Explanation:

Given data:

Average atomic mass of neon = ?

Abundance of Ne-20 = 90.00%

Abundance of Ne-22 = 10.00%

Solution:

Average atomic mass  = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass  = (90.00×20)+(10.00×22) /100

Average atomic mass =  1800 + 220 / 100

Average atomic mass = 2020 / 100

Average atomic mass = 20.2 amu.
