how many moles react with 11 moles of oxygen

Answer:

The amount of sun that is being reflected and how hot the sunlight being reflected is

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  

2

moles of hydrogen gas and  

1

mole of oxygen gas to produce  

2

moles of water.

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  

6.0

moles of oxygen. Assuming that hydrogen gas is not a limiting reagent, you can say that the reaction will produce

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.

Answer:

Oxidation

Explanation:

Mg loses 2e- for it to gain it's stability hence the reaction above is oxidation

note: Oxidation is the loss of electrons while reduction is the gain of electrons

Answer:

The Sun, like others stars, is a ball of gas. In terms of the number of atoms, it is made of 91.0% hydrogen and 8.9% helium. By mass, the Sun is about 70.6% hydrogen and 27.4% helium.

Explanation:

helium is probs ur answer!

Answer:

A) Electrons

A) 16-8=8 so it'd be 8

(Relative atomic mass - atomic number = neutrons)

A) 12

Same thing as last one.

31-15=16 ( did you type the wrong options if not then huh?)

Explanation:

Answer:

27.03 grams

Explanation:

moles (n) = mass(m)/Molar mass(M)

moles = 1.59

mass = ?

N = 14, H = 1

M(NH3) = 14 + 3(1) = 17

Substitute the values into the equation:

nM = m

∴ m = 1.59 × 17 = 27.03

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:

The correct answer is - 2Cu + 4HBr → 2H[CuBr2] + H2

Explanation:

Copper (Cu) and hydrobromic acid (HBr), which is a dissolved form of hydrogen bromide in the water, react and produce hydrogen dibromidocuprate (I) and hydrogen molecules.

The complete and balanced equation is -

2Cu + 4HBr → 2H[CuBr2] + H2

This reaction takes place in the medium of ester. Copper is in the suspension form in this reaction.

Thus, the correct answer is - 2Cu + 4HBr → 2H[CuBr2] + H2

Answer: 0.0054 s

Explanation: There is an inverse relation between the frequency  and the period  of a wave (a sound wave in this case):

T=1/F

Where f = 1.85 (10)² H z

Hence : T = 1/1.85 (10)² H z T =0.0054s
