Chemistry
1 answer:
Naddik [55]3 years ago
4 0

Answer:

Mutualism is the doctrine that mutual dependence is necessary to social well-being.

Commensalism is an interaction between two organisms living together in more or less intimate association in a relationship in which one benefits and the other is unaffected.

Parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterized parasites as "predators that eat prey in units of less than one"

What does the 4 indicate in 1s22s22p4? 4th subshell 4 electrons 4th energy level
kupik [55]

Answer: The number 4 indicates 4 electrons.

Explanation: We are given an electronic configuration, which is:

1s^22s^22p^4

Here,

  • The letters denote the sub-shells of an element.
  • The numbers written before the letters which are 1, 2 and 2 represents the Principle Quantum Number and these represents the energy level of the sub-shells.
  • The number which are written in the superscripts which are 2, 2 and 4 denotes the electrons which are present in the sub-shell.

Hence, 4 indicates 4 electrons present in 2p sub-shell.

What is the hydronium ion concentration of a 0.100 M acetic acid solution with Ka = 1.8 × 10-5? The equation for the dissociatio
evablogger [386]

Answer:

1.3×10⁻³ M

Explanation:

Hello,

In this case, given the dissociation reaction of acetic acid:

CH_3CO_2H(aq) + H_2O(l) \rightleftharpoons H_3O^+(aq) + CH_3CO_2^-(aq)

We can write the law of mass action for it:

Ka=\frac{[H_3O^+][CH_3CO_2^-]}{[CH_3CO_2H]}

Of course, excluding the water as heterogeneous substances are not included. Then, in terms of the change x due to the dissociation extent, we are able to rewrite it as shown below:

1.8x10^{-5}=\frac{x*x}{0.100-x}

Thus, via the quadratic equation or solve, we obtain the following solutions:

x_1=-0.00135M\\x_2=0.00133M

Obviously, the solution is 0.00133M which match with the hydronium concentration, thus, answer is: 1.3×10⁻³ M in scientific notation.

Regards.

A selectively permeable membrane separates solution a and
Yakvenalex [24]
The water molecules will flow from b to a due to osmosis.

Osmosis is where water molecules will flow from a region of higher water potential to a region of lower water potential, through a selectively permeable membrane.

When the water molecule concentration is higher, it has a higher water potential top. Water potential is the tendency for them to flow to a lower region.

The net movement will stop until both sides of the solution has a same water potential.

Which elements are in the same period?
worty [1.4K]

Answer:

Elements that are in the same period have chemical properties that are not all that similar. Consider the first two members of period 3: sodium (Na) and magnesium (Mg). In reactions, they both tend to lose electrons (after all, they are metals), but sodium loses one electron, while magnesium loses two.
