i think it is..... smaller than normal range of highs and low tides  

Moon and Sun are at right angles to the Earth

Explanation:

Moon and Sun are at right angles to the Earth and gravity of the Sun and Moon work against is the right statement about NEAP tides.

Tides are the cyclic deformation of water body occur due to external gravitational force.

NEAP tides are also known as small tides as their heights are not very much and this is occur due to opposite attraction of water towards the gravity of the sun and moon. As sun and moon are present in the right angle direction with respect to the earth.

Hence, option (1) & (2) is correct, i.e. gravity of sun and moon is opposite and they are present at the right angle to the earth.

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:

Los alcoholes de cadena larga tienen altos puntos de ebullición. Además, cuando tienen ramificación, el punto de ebullición disminuye

Explanation:

El punto de ebullición de un alcohol se ve afectado, las interacciones dipolo-dipolo, las fuerzas de dispersión de van der Waals y los enlaces de hidrógeno.

Las fuerzas de las interacciones dipolo-dipolo y los enlaces de hidrógeno son más o menos las mismas en la serie de alcohol en serie, sin embargo, a medida que aumenta la longitud del alcohol, las fuerzas de dispersión de van der Waals aumentan debido al aumento de la atracción dipolo-dipolo.

Sin embargo, a medida que el alcohol se vuelve más ramificado, el área de la superficie aumenta, lo que disminuye las fuerzas de van der Waals, de modo que se requiere menos fuerza para separar las moléculas y hervir una muestra del alcohol.

Por tanto, los alcoholes de cadena larga tienen puntos de ebullición elevados. Además, cuando tienen ramificación, el punto de ebullición disminuye.

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:

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.

The object will become statically charged

Explanation:

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

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

Notice that the reaction requires

This tells you that the reaction produces twice as many moles of water as you have moles of oxygen gas that take part in the reaction.

You know that your reaction uses

Answer:

A. Antibiotic resistance can sometimes be shared among bacteria.

B. Mutation can cause antibiotic resistance.

D. Antibiotics killing bacteria while allowing mutated bacteria to live is an example natural selection.

Explanation:

Identifying: Archaea have cell walls that lack peptidoglycan and have membranes that enclose lipids with hydrocarbons rather than fatty acids (not a bilayer). ... Bacteria: cell membrane contains ester bonds; cell wall made of peptidoglycan; have only one RNA polymerase; react to antibiotics in a different way than archea do.

Hope this helps, I reported some answer that was absurd, not applicable, incomplete and confusing

Mutation can cause antibiotic resistance, Bacteria that become resistant are an example of evolution. Antibiotics killing bacteria while allowing mutated bacteria to live is an example natural selection The correct options are B, D, and C.

Archaea, like bacteria, lack interior membranes but have a cell wall and swim with flagella.

Archaea differ from bacteria in that their cell wall lacks peptidoglycan and their cell membrane contains ether linked lipids rather than ester linked lipids.

The dispersion of antibiotic resistance in pathogenic bacteria is a simple and elegant example of natural selection at work.

Bacteria can develop antibiotic resistance through mutations that alter antibiotic cellular targets or by acquiring dedicated resistance genes from other bacteria.

Antibiotic resistance can be caused by mutation; bacteria that become resistant are an example of evolution. Natural selection is demonstrated by antibiotics killing bacteria while allowing mutated bacteria to live.

Thus, B, D, and C are correct options.
