A SERIES CIRCUIT is a closed circuit with one path. a. True b. False

2 answers:

5 0

A series circuit is a closed circuit where the current follows one path. In a series circuit, the devices along the circuit loop are connected in a continuous row, so that if one device fails or is disconnected, the entire circuit is interrupted.

TRUE the devices in a series circuit are connected in a continuous row so if one device fails they all fail

Write the balanced nuclear equation for the following. (Use the lowest possible coefficients. Omit states-of-matter in your answ

olga55 [171]

Answer:

$_{93}^{232}\text{Np} + _{-1}^{0}\text{e} \longrightarrow _{92}^{232}\text{U}$

Explanation:

The unbalanced nuclear equation is

$_{93}^{232}\text{Np} + _{1}^{0}\text{e} \longrightarrow ?$

It is convenient to replace the question by an atomic symbol, $_{x}^{y}\text{Z}$ , where x = the atomic number, y = the mass number, and Z = the symbol of the element.

$_{93}^{232}\text{Np} + _{1}^{0}\text{e} \longrightarrow _{x}^{y}\text{Z}$

Then your equation becomes

$_{93}^{232}\text{Np} + _{1}^{0}\text{e} \longrightarrow _{x}^{y}\text{Z}$

The main point to remember in balancing nuclear equations is that the sums of the superscripts and of the subscripts must be the same on each side of the equation.

Then

93 – 1 = x, so x = 92

232 + 0 = y, so y = 232

Element 92 is uranium, so the nuclear equation becomes

$_{93}^{232}\text{Np} + _{-1}^{0}\text{e} \longrightarrow _{92}^{232}\text{U}$

Below is the structure of acetyl chloride, drawn with bonds and electron dots. determine how many nonbonding and bonding electro

erma4kov [3.2K]

Answer : The non-bonding and bonding electrons are 10 and 14 respectively.

Explanation :

Electron-dot structure : It is also known as Lewis-dot structure. It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

The given molecule is, Acetyl chloride $(CH_3COCl)$

Carbon has '4' valence electrons, hydrogen has '1' valence electron, oxygen has '6' valence electrons and chlorine has '7' valence electrons.

Therefore, the total number of valence electrons in $(CH_3COCl)$ = 2(4) +3(1) +6 +7 = 24

According to electron-dot structure, there are 14 number of bonding electrons ans 10 number of non-bonding electrons.

The electron-dot structure of $(CH_3COCl)$ is shown below.
