water resists changing its temperature because it has a high specific heat. true or false?

Based on the trend of electronegativities values of the elements Be, Mg, Ca, and, Sr within their group (increasing from bottom to top), the atoms of the element Sr will have the least attraction for an electron.  

We need to remember that electronegativity indicates the affinity or attraction of an element for an electron. Hence, the higher the electronegativity, the higher the attraction of that element for an electron.  

The values of electronegativities of the given elements are the following:

Be = 1.57

Mg = 1.31

Ca = 1.0

Sr = 0.95

We can see that the increasing trend of electronegativities in this group is from the bottom to the top, having the Sr with the lowest electronegativity value and the Be with the highest.  

This trend is related to atomic size, the larger the atomic size, the lower the electronegativity because the electron in the outermost shell will feel less attraction towards the nucleus of an atom. In a group of the periodic table, the size of an atom will increase from top to bottom.          

Therefore, according to the said above, the atoms of the Sr will have the least attraction for an electron (it has the lower electronegativity value).

Explanation:

The molar mass of a compound can be calculated by finding the molar of the individual atoms that combine to make the compound.

Molar mass of compound =

         ∑ (molar mass of element × number of atoms of the element)

∴ Molar mass of dimethylglyoxime

                 = 4C + 8H + 2N + 2O

                 = [(4 × 12.011) + (8 × 1.0080) + (2 × 14.007) + (2 × 15.999)] g/mol

                 = 116.12 g/mol

Answer

No you did not lose weight.

Explanation:

Weight is the force acting on an object, Gravity is a force on earth which does not apply to the moon so your weight may change depending in where you are but your mass will stay the same because mass measures the matter of an object ITSELF! Have a nice day....

Answer:

I would take my weight on Earth and divide it by  6. I'd weigh less because the gravitational pull on the Moon is less, and, weight is the measure of gravitational pull. I wouldn't "loose weight" because I'd weigh the same on Earth  as I did the day I left (give or take a few pounds).

Answer:

Nonbiodegradable substance

At a fixed temperature and pressure, a cylinder contains equal volumes of O2 and an unknown gas. The identity of the unknown gas CO.

The number of moles of a given substance is calculated by dividing the mass by the molar mass.

The number of moles of O₂ = [tex]\mathbf{=\dfrac{20.0 \ g}{32 \ g/mol}}[/tex]

= 0.625 moles.

Based on the given assumption, at fixed temperature and pressure;

The molar mass of the unknown gas can be estimated as:

[tex]\mathbf{= \dfrac{mass}{number \ of \ moles}}[/tex]

[tex]\mathbf{= \dfrac{17.5 \ g}{0.625 \ moles}}[/tex]

= 28 g/mol

Therefore, we can conclude that the unknown gas is CO.

The cart starts out in position A with high potential energy, low kinetic energy, and some thermal energy. As the cart progresses into position B, the kinetic energy begins to increase and the potential energy begins to decrease; as the thermal energy increases as thermal energy from the track is transferred to the cart through friction. Once the cart reaches position C, it has high kinetic energy, low potential energy, and some thermal energy. At position D, the cart has high potential energy, low kinetic energy, and some thermal energy. The potential energy throughout is correlated to gravity, the kinetic energy is correlated to momentum, and the thermal energy is correlated to friction. The potential energy is at its maximum during position A, and its minimum at position C; the kinetic energy is at its maximum during position C, and its minimum at position A; the thermal energy is at its maximum during position B, and its minimum at position A

Taking into account the definition of density and Archimedes' principle, the beginner bowling ball will float on the water.

But first it is neccesary to know that density is a quantity referred to the amount of mass in a certain volume of a substance or a solid object.

In other words, the density is the relationship between the weight (mass) of a substance and the volume that the same substance occupies.

The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

[tex]density=\frac{mass}{volume}[/tex]

In this case, a beginner's bowling ball has a mass of 4.9 kg and a volume of 5.4 liters. This is:

Replacing in the definition of density:

[tex]density=\frac{4900 g}{5400 mL}[/tex]

Solving:

density=0.907 [tex]\frac{g}{mL}[/tex]

On the other hand, Archimedes' principle says that an object immersed in a liquid experiences an upward vertical force equal to the weight of the volume of the dislodged liquid.

The sinking or floating of an object is determined by its density with respect to that of the liquid in which it is submerged.

Considering water as the liquid where the object is submerged in this case, an object with a higher density than water will sink. In contrast, an object with a lower density than water will float.

In this case, considering that water has a density of 1 [tex]\frac{g}{mL}[/tex], the bowling ball for beginners has a lower density. This indicates that, having a lower density than water, the object will float.

In summary, the beginner bowling ball will float on the water.
