What is true of intercellular signals that do not go through direct connections between cells, such as plasmodesmata?

2 answers:

6 0

I believe that what happens here is that when those cells carrying those intercellular signals do no pass through the connections, actually the signal is passed through or are transferred to adjacent cells for signal transmission, hence the answer is:

How many atoms are present in 0.10mol of ptcl2 (nh3)2?

serious [3.7K]

The number of atoms present in 0.10 mol of PtCl2(NH3) is calculated using Avogadro law formula

that is

1 mole = 6.02 x10^23 atoms
what about 0.10 moles = ? atoms

= 6..02 x10 ^23 x 0.1 = 6.02 x10^22 atoms

The element iodine forms a(n) _______ with the charge . The symbol for this ion is , and the name is . The number of electrons i

-BARSIC- [3]

Answer:

The element iodine forms an anion with the charge -1. The symbol for this ion is I⁻¹, and the name is iodide. The number of electrons in this ion is 7.

Explanation:

Hello,

In this case, we have to consider iodine has the capacity to accept the electrons lost by other elements such as metals or hydrogen by becoming negatively charged. Such phenomena makes iodine to form an anion (negatively charged) with the charge -1, since it only needs one electron to attain the octet. Moreover, the symbol of such ion is I⁻¹ and its name is iodide. By cause of the aforementioned, the number of electrons it has is 7 since at its outer shell seven electrons are found (see electron configuration Kr,5s²,5p⁵).

Best regards.

How many protons and neutrons are in the nucleus of isotope with mass of 68.926 amu?

Sidana [21]

There are 30 protons and 39 neutrons in the nucleus.

This must me the isotope of an element with an atomic mass close to 69 u.
The only candidates are Zn and Ga.
Zn has a zinc-69 isotope with mass 68.926 u.
Ga has a gallium -69 isotope with mass 68.925 u.
The isotope is probably $_{30} ^{69}Zn$ .
It has 30 protons and 39 neutrons.
