Select the electron-domain geometry for a molecule with three bonding domains and one nonbonding domain. A) Linear B) Trigonal planar electron-domain geometry C) Tetrahedral D) Trigonal bipyramidal E) Octahedral

Step-by-step answer

P Answered by PhD

The electron-domain geometry for a molecule with three bonding domains and one nonbonding domain is D. Trigonal pyramidal.

When all the electron domains are bonding, it's tetrahedral. If one of the domains is non-binding pair, it's trigonal pyramidal.

In a situation where there are two non-binding pairs, it's bent. Therefore, electron-domain geometry for a molecule with three bonding domains and one nonbonding domain is trigonal pyramidal.

Choose the answer which gives the electron-domain geometry and molecular geometry which are both correct for CS2 . a) The electron-domain geometry is tetrahedral. The molecular geometry is T-shaped. b) The electron-domain geometry is linear. The molecular geometry is T-shaped. c) The electron-domain geometry is linear. The molecular geometry is bent. d) The electron-domain geometry is tetrahedral. The molecular geometry is bent. e) The electron-domain geometry is linear. The molecular geometry is linear.

Step-by-step answer

P Answered by PhD

The electron-domain geometry is linear. The molecular geometry is linear.

Explanation:

According to the valence shell electron pair repulsion theory (VSEPR), the shape of a molecule depends on the arrangement of electron pairs present on the valence shell of the central atom of the molecule. Electron pairs are arranged in such a way as to minimize repulsion between them. The electron pairs are positioned as far apart in space as possible.

In CS2, both the molecular and electron pair geometries are linear because the electron pairs and bonding groups are positioned at an angle of 180° from each other. Hence the answer.

The graph models the function f(x) = 2(1/2)x. what is the domain and range of the function? a-domain: x 0; range: y 0 b-domain: x 0; range: all real numbers c-domain: all real numbers; range: y 0 d-domain: all real numbers; range: y ≥ 0 explain with the answer

Step-by-step answer

P Answered by PhD

Hello!

Given the function, $f(x) = 2(\frac{1}{2})^{x}$ , notice that the function f(x) is an exponential function.

All exponential functions have a horizontal asymptote at y = 0, and this means that the graph never goes over the line y = 0. Therefore, the range is less than zero, but never equal to zero.

Also, this means that the domain of the function f(x) is all real numbers because as we substitute positive x-values into the function, the graph goes closer to zero, but never across zero. But, if we substitute negative x-values into the equation, it goes to infinity.

Therefore, the answer is choice C. The domain of f(x) is all real numbers, and the range is y > 0.

What statement regarding trust relationships between domains is accurate? a. if domain a and b have a trust and domain b and c have a trust, domain a does not automatically trust domain c. b. due to the trust relationship between parent and child domains, any one domain can have access to the resources of all others. c. the security in a two-way trust relationship between domains is based on radius security techniques. d. a new domain joining a tree has no trust relationships with the other domains in the same tree.

Step-by-step answer

P Answered by PhD

The correct answer is letter "C": Due to the trust relationship between parent and child domains, any one domain can have access to the resources of all others.

Explanation:

Domain names are useful to recognize IP addresses -yahoo.com, for instance. All the equipment sharing at least part of the IP address is said to be under the same domain. A domain controller is a machine where the domain is installed. Then, a child domain is another domain inside the main domain also called the parent domain. As the child domain is subject to the parent domain, they both have access to the information shared between one another.

The domain is the set of x-values for which the graph exists and the range is the set of y-values for which the graph exists; in this case, the graph exists for all real values of x and for y ≤ 3, thus the answer is C
