Which layer is least dense

Answer:

As you can see from the picture, about half the moon is visible.

Half = 1/2 = 50%

So, C is the  correct answer.

Let me know if this helps!

Fifty  percent of the moon is visible in the last quarter moon phase shown in the image.

The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet,with a diameter about one-quarter that of Earth (comparable to the width of Australia).

The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at 0.1654 g, with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density.

The Moon orbits Earth at an average distance of 384,400 km (238,900 mi), or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days.

Answer:

chloroplast is the correct answer

Answer: it would be cation, 2+

Explanation: electrons are negatively charged by 1. So if you get rid of 2 electrons it would be positive and cation is used to represent positive ions.

The electrical charge of the calcium ion is +2.

Explanation:

Your tools of choice for stoichiometry problems will always be the mole ratios that exist between the chemical species that take part in the reaction.

As you know, the stoichiometric coefficients attributed to each compound in the balanced chemical equation can be thought of as moles of reactants needed or moles of products formed in the reaction.

In your case, the balanced chemical equation for this synthesis reaction looks like this

Explanation:

Answer: The temperature of the gas at a pressure of  0.987 atm and volume of 144mL is [tex]25.16^0C[/tex]

Explanation:

The combined gas equation is,

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

where,

[tex]P_1[/tex] = initial pressure of gas = 0.947 atm

[tex]P_2[/tex] = final pressure of gas = 0.987 atm

[tex]V_1[/tex] = initial volume of gas = 150 ml

[tex]V_2[/tex] = final volume of gas = 144 ml    

[tex]T_1[/tex] = initial temperature of gas = [tex]25^0C=(25+273.15)K=298.15K[/tex]

[tex]T_2[/tex] = final temperature of gas = ?

Now put all the given values in the above equation, we get:

[tex]\frac{0.947\times 150}{298.15}=\frac{0.987\times 144}{T_2}[/tex]

[tex]T_2=298.31K=(298.31-273.15)^0C=25.16^0C[/tex]

The temperature of the gas at a pressure of  0.987 atm and volume of 144mL is [tex]25.16^0C[/tex]

Answer:

[tex]CaN_{2} O_{6}[/tex]

Explanation:

When calculating an empirical formula from percentages, assume you have a 100g sample. This allows you to convert the percentages directly to grams, because X % of 100g is X grams.

So:

24.42 % = 24.42 g Ca, 17.07% = 17.07g N, 58.5% = 58.5g O

The next step is to divide each mass by their molar mass to convert your grams to moles.

24.42/40.08 = 0.6092 mol

17.07/14.01 = 1.218 mol

58.85/15.99 = 3.680 mol

Then you will divide all of your mol values by the SMALLEST number of moles. This gives you whole numbers that are the mole ratio (subcripts) of the empircal formula.

0.6092 mol/0.6092 mol = 1

1.218 mol/0.6092 mol = 2

3.680 mol/0.6092 mol = 6

So the empirical formula is [tex]CaN_{2} O_{6}[/tex]

Answer:

0.35 M

Explanation:

HCl + NaOH --> NaCl + H2O

Since the ratio HCl : NaOH is 1:1, you can apply the formula:

Ma x Va = Mb x Vb

Vb = 14 ml (based on the table)

Va = 10 ml

Mb = 0.25 M

Ma = (Mb x Vb)/Ma = (14 x 0.25)/ 10 = 0.35 M

Answer:

I am pretty sure it has 10 kernel electrons!?!?!?

Hope this helps!!!

Have a great day!!! :)

Answer: 22.33 M

Explanation:

molarity = moles of solute/liters of solution or [tex]M=\frac{mol}{L}[/tex]

first we have to find our moles of solute (mol), which you can find by dividing the mass of solute by molar mass of solute

mass of solute: 285 g

molar mass of solute: 36.46 g/mol

let's plug it in:

[tex]\frac{285g}{36.46 g/mol} = 7.817 mol[/tex]

next, we plug it into our original equation:

[tex]\frac{7.817 mol}{0.350 L} = 22.33 M[/tex]

Answer:

Energy is converted in a hydroelectric plant as follows;

The kinetic energy of water turns turbines; the mechanical energy of the turbines turns the generator, which produces electrical energy

Explanation:

The water in an hydroelectric plant is given potential energy by building an artificial dam to raise the height of the water above the turbine

The high potential energy of the water is converted to kinetic energy which provides the power that turns the turbine transforming the kinetic energy of the water into rotational kinetic energy of the turbine by conservation of mechanical energy;

The shaft connected between the turbine and the generator, turns the generator by the mechanical energy of the turbine and as the generator turns in a magnetic field, electricity is produced by magnetic induction according to Faraday's law.
