Answer:

The correct answer is - A. Ethanol reduces air pollution.

Explanation:

Ethanol is believed to be better fuel for the environment than other petroleum fuels. Ethanol emits lower carbon dioxide as it is clean smokeless fuel, and produces less or the same oxides of nitrogen and hydrocarbons.

It is produced by the process of fermentation of molasses by yeast. Mixing it with the other fuels is found to be CO2 reduces by 30% of emissions to the atmosphere.

Answer:

Explanation:

A hydrogen atom has an atomic number of 1.

So it's proton number will always be 1.

A neutral hydrogen atom does not have any charge.

So it has the same amount of electrons as protons, which turns out to be also 1.

A neutral hydrogen atom has an atomic mass of ≈

1.00794 amu ≈ 1 amu.

To find the amount of neutrons, we take the proton number and subtract it from the mass number.

1 − 1 = 0

So a neutral hydrogen atom has no neutrons.

In summary,

A hydrogen atom has

1 proton

1 electron

0 neutrons

Answer:

El átomo podes 1 protón, 1 electrón y 2 neutrones.

Explanation:

Cada elemento químico se caracteriza por el número de protones de su núcleo, que se denomina número atómico Z. Es decir, el número atómico​ de un elemento químico es el número total de protones que tiene cada átomo de ese elemento.

Los protones poseen carga positiva y se encuentran en el núcleo, en torno al cual se mueven otras partículas con carga eléctrica negativa que son los electrones. Así, el átomo es eléctricamente neutro, ya que la carga positiva de los protones está compensada por la carga negativa de los electrones.  Entonces, en todo átomo neutro el número de protones del núcleo es igual al de electrones de sus orbitales.

En este caso, un átomo neutro tiene número atómico 1. Entonces la cantidad de protones y electrones presentes en el átomo es 1.

En el núcleo de cada elemento, además de protones, también es posible encontrar neutrones, cuyo número puede variar. La masa atómica (A) se obtiene sumando el número de protones y de neutrones de un núcleo determinado:

Número másico (A) = número de protones + número de neutrones

En este caso, el átomo neutro posee 1 protón y su número másico es 3. Entonces:

3= 1 + número de neutrones

Resolviendo:

3 - 1= número de neutrones

2= número de neutrones

Entonces, el átomo podes 1 protón, 1 electrón y 2 neutrones.

Explanation:

Here is why: If the atmosphere contains too much of these gases, the whole Earth becomes a hotter and hotter greenhouse. The atmosphere holds onto too much of the heat at night instead of letting it escape into space. Then, the next day, the Sun heats Earth's surface even more.

Answer:

The earth's rotation, earth is rotating, so one side of earth will be hit by the sun, and the other wont be hit, making it dark, but since earth rotates, it causes it to turn, making one side have daylight, and the other, darkness, which the light you see is from the sun's reflection on the moon

Answer:

Number of atoms is equal.

Explanation:

1 mol of anything contains NA particles.

NA is known as Avogadro's number, 6.02×10²³

We determined the moles of each compound. Both molecules are dyatomic,

H₂  → 2.02 g . 1mol / 2.016 g = 1 mol

O₂ →  32 g . 1mol / 32g = 1 mol

Both have the same amount of moles.

In conclussion, the number of atoms is the same in both samples.

(C) 320 g

Explanation:

A = A02^(-t/hl)

where hl = half-life

A0 = original amount

A = present amount

t = elapsed time = 5 half-lives

10g = A02^(-5) = A0/32

A0 = 32×(10 g) = 320 g

Answer:

It would be to low

Explanation:

If some salt were accidently spilled as it was transferred from  balance to  cup  calculated enthalpy of solution of salt be too low as there will be loss in mass  which would lead less solubility of salt and hence less enthalpy.

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

According to molar concentration, 100 ml of 10 M solution is needed to make 1 liter of a 1 M solution.

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.In case of two solutions, molar concentration is found out by, M₁V₁=M₂V₂.

On substitution in above formula, V₁=1×1/10=0.1 L=100 ml.

Thus, 100 ml  of a 10 M solution is needed to make 1 liter of a 1 M solution.

Answer:

Evolution in the broadest sense explains that what we see today is different from what existed in the past. Galaxies, stars, the solar system, and earth have changed through time, and so has life on earth.Something that happened in the past is thus not "off limits" for scientific study. Hypotheses can be made about such phenomena, and these hypotheses can be tested and can lead to solid conclusions. Furthermore, many key aspects of evolution occur in relatively short periods that can be observed directly—such as the evolution in bacteria of resistance to antibiotics.Laws, like facts and theories, can change with better data. But theories do not develop into laws with the accumulation of evidence. Rather, theories are the goal of science.

Number of atoms in 5.9 g of N2 = 1.268 *10^23

Explanation:

Weight of one mole of N2 is 28.0134 g

In one mole of N2, number of atoms = 6.023 *10^23

Number of atoms in 28.0134 g (one mole) of N2 =  6.023 *10^23

Number of atoms in 1 g of N2 = 6.023 *10^23/28.0134

Number of atoms in 5.9 g of N2 = 6.023 *10^23/28.0134 * 5.9

= 1.268 *10^23

Explanation:

Steaming up or fogging happens when steam condenses on the mirror. Steam emerging from hot water can condense on a colder surface. That’s the reason you can see the result on a mirror instantaneously. Obviously, for a bathroom mirror to steam up, the steam that originates at the shower spray (or the bathtub) has to travel through the cooler air to reach the mirror. Since air tends to heat up easily, the mirror can steam up fast.
