Answer: -

24 grams per kilogram.

Explanation: -

We know that

The mixing ratio = actual (measured) mass of water vapor (in parcel) in grams / mass of dry (non water vapor) air (in parcel) in kilogram

The saturation mixing ratio = mass of water vapor required for saturation (in parcel) in grams/ mass of dry (non water vapor) air (in parcel) in kilograms

Relative humidity = actual (measured) water vapor content/ maximum possible water vapor amount (saturation)

Thus saturation mixing ratio = Mixing ratio / relative humidity

= 6 / (25/100)

= 24

Pavel [41]

Answer:

<em>Protons: </em>

  • Positively charged particle
  • The number of these is the atomic number
  • All atoms of a given element have the same number of these

<em>Neutrons:  </em>

  • Neutral particles  
  • Isotopes of a given element differ in the number of these
  • The mass number is the number of these added to the number of protons

Explanation:

Protons (<em>positively charged</em>), neutrons (<em>neutral</em>) and electrons (negatively charged) are smaller than an atom and they are the main subatomic particles.  The nucleus of an atom is composed of protons and neutrons, and the electrons are in the periphery at unknown pathways.

The <em>Atomic number</em> (Z) indicates the number of protons (P^{+}) in the nucleus. Every atom of an element have the <em>same atomic number</em>, thus the <em>same number of protons</em>.

The <em>mass number </em>(A) is the sum of the <em>number of protons</em>  (P^{+}) <em>and neutrons</em> (N) that are present in the nucleus: <em>A= Z + N</em>

<em>Isotopes</em> are atoms of the <em>same element </em>which nucleus have the <em>same atomic number</em> (Z), and <em>different mass number (A)</em>, it means the <em>same number of protons</em> (P^{+}) and a <em>different number of neutrons</em> (N). For example, the oxygen in its natural state is a mixture of isotopes:

99.8% atoms with A= 16, Z=8, and N=8

0.037% atoms with A=17, Z=8, and N=9

0.204% atoms with A=18, Z=8, and N=10

Enter a balanced equation for the reaction between solid silicon dioxide and solid carbon that produces solid silicon carbide an
givi [52]

Answer:

SiO2(s) + 3C(s)  ------> SiC(s) + 2CO(g)

Explanation:

The formula for silicon oxide is SiO2 and carbon is C. silicon carbide is SiC

and carbon monoxide is CO.

An arrow is always used to separate the reactants (left) and products (right).

A balanced equation must contain equal number of atoms in each side of the equation.

For example in the equation above, there are 1 atom of silicon appears on each side; 2 atoms of oxygen and three atoms of carbon.

Which atom, selenium (Se) or Arsenic (As), has the higher electron affinity and why?
IrinaVladis [17]

Answer:

5. Selenium, because it does not have a stable, half-filled p subshell and adding an electron does not decrease its stability.

Explanation:

Electron affinity is the amount of energy released when an isolated gaseous atom accepts electron to form the corresponding anion.

Selenium:-

The electronic configuration of the element is:-

[Ar]3d^{10}4s^24p^4

Arsenic:-

The electronic configuration of the element is:-

[Ar]3d^{10}4s^24p^3

The 4p orbital in case of arsenic is half filled which makes the element having more stability as compared to selenium.

Thus, selenium has higher electron affinity because adding electron does not decrease the stability as in case of arsenic.
