What is this equation balanced?

Answer:

The earth

Since it is shown in the chart that, Earth is inner corner is the smallest.

Our Sun will eventually turn into a red giant in the cooler temperature and high luminosity and in the white dwarf phase has a hot temperature & dim luminosity.

In astronomy, the Hertzsprung-Russell diagram, often known as the H-R diagram, is a graph that plots the absolute magnitudes (intrinsic brightness) of stars against their spectral classifications (temperatures).

From the given diagram it is clear that when sun turns into a red giant then the temperature decreases and luminosity increases as it becomes large in size. And when it finally become a white dwarf then temperature comparatively increases and luminosity gets dim due to smaller size.

Hence in the red giant phase sun has a cooler temperature and high luminosity and in the white dwarf phase has a hot temperature & dim luminosity.

Answer:

The scale reads the tension in the string. The tension in the string is 100 N. This is the force the string must exert up on either of the 100-N weights at either end of the string.

Nothing is moving, nothing is accelerating, so the net force on the spring is zero. Likewise, the net force on either of the 100-N weights is also zero. But that is another question. The spring scale does not measure the net force. The spring scale simply measures the tension, the magnitude of the force exerted by the string.

Explanation:

Answer: aluminium, mercury , platinum and copper.

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.

A general single displacement reaction can be represented as :

[tex]XY+Z\rightarrow XZ+Y[/tex]

Thus the metals which are more reactive than magnesium will react with magnesium sulphate solution.

The metals which are more reactive than magnesium are aluminium, mercury , platinum and copper.

Answer:

Molecular formula = C₄H₁₂O₂

Explanation:

Given data:

Percentage of hydrogen = 13.80%

Percentage of carbon = 51.02%

Percentage of oxygen = 35.18%

Molecular formula = ?

Solution:

Number of gram atoms of H = 13.80 / 1.01 = 13.6

Number of gram atoms of O = 35.18 / 16 = 2.2

Number of gram atoms of C = 51.02 / 12 = 4.25

Atomic ratio:

            C                      :      H             :         O

           4.25/2.2           :     13.6/2.2     :       2.2/2.2

            2                      :        6          :        1

C : H : O = 2 : 6 : 1

Empirical formula is C₂H₆O.

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass = C₂H₆O = 46 g/mol

n = 88 / 46

n = 2

Molecular formula = n (empirical formula)

Molecular formula = 2 (C₂H₆O)

Molecular formula = C₄H₁₂O₂

b)

1 : 2 : 2 (I don't know if this is what the question wants but it is what I would answer)

c)

Hydrogen because it requires 2 moles of H2 to react with 1 mole of O2

d)

24 moles of water. Look at stoichiometric coefficient. 2:2 means 24 moles you get 24 moles

e)

Oxygen. 2 < 5/2. Remember, 1 mole of O2 requires 2 moles of H2. But 5/2 is still greater than 2

f)

First, let's find out how many moles of water we can get. Since O2 is the limiting reactant, and O2:H2O ratio is 1:2, we will get 4 moles of H2O. Then, we can multiply 4 by Avogadro's number which is [tex]6.022*10^{23}[/tex] to get the number of molecules. We get: 2.41 * 10^24 molecules of water.

Answer:

[tex]T_1 = -57.15^{\circ}C[/tex]

Explanation:

Given

[tex]P_1 = 650mmHg[/tex] --- Initial Pressure

[tex]V_1 = 5.0L[/tex] --- Initial Volume

[tex]V_2 = 5.7L[/tex] --- Final Volume

[tex]P_2 = 800mmHg[/tex] --- Final Pressure

[tex]T_2 = 30C[/tex] ---- Final Temperature

Required

Determine the initial temperature (T1)

This question will be solved using combined gas law which states:

[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}[/tex]

However, the final temperature must be converted to degree kelvin

[tex]T_2 = 30C[/tex] --- Add 273.15

[tex]T_2 = 30k + 273.15 k[/tex]

[tex]T_2 = 303.15k[/tex]

Make T1 the subject in [tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}[/tex]

[tex]T_1 = \frac{P_1V_1T_2}{P_2V_2}[/tex]

Substitute values for P1, V1, T2, P2 and V2

[tex]T_1 = \frac{650 * 5.0 * 303.15}{800 * 5.7}[/tex]

[tex]T_1 = \frac{985237.5}{4560}[/tex]

[tex]T_1 = 216.060855263[/tex]

Approximate

[tex]T_1 = 216k[/tex]

Convert to degree Celsius

[tex]T_1 = 216k[/tex] --- Subtract 273.15

[tex]T_1 = 216 - 273.15[/tex]

[tex]T_1 = -57.15^{\circ}C[/tex]

Hence, the initial temperature is -57.15C

Answer:

The magnetic field line data refutes the claim that the magnets were misaligned in the Tuesday launch.

Explanation: The data shows that there was no difference in the pattern of the field lines for all three launches. If the magnets in Tuesday's test had been misaligned, the force between the magnets in that test would be different than in the other test, showing both attraction and repulsion. During a misalignment at least one field line would connect opposite poles of the other magnets, but the magnetic field lines data we received did not show proof of misalignment.  Therefore the magnets were correctly aligned on Tuesday.

Advantage and disadvantage of asexual reproduction in plant is described below in details.

Explanation:

An advantage of asexual reproduction is that the resulting plant will approach adulthood quicker. Since the new plant is emerging from a grown-up plant or plant components, it will also be stronger than a seed. Asexual reproduction can take a spot by natural or manufactured (assisted by humans) means.

The significant disadvantages of asexual reproduction are the Shortage of diversity. Following the seeds are genetically the same as the parent they are more sensitive to the same diseases and nutrient insufficiencies as the parent. All the negative deviations endure for generations.
