Bogdan [553]3 years ago
5 0

Answer:

96g

Explanation:

Given parameters:

Number of moles of NaOH = 2.4moles

Unknown:

Mass of NaOH = ?

Solution:

The mass of a substance given the number of moles can be found using the expression below;

     Mass of NaOH  = Number of moles x molar mass;

  Molar mass of NaOH  = 23 + 16 + 1 = 40g/mol

Now input the parameters and solve;

    Mass of NaOH  = 2.4 x 40  = 96g

Answer:

4-wheeler

Explanation:

I was thinking that you could say this:

My design is that the 4-wheeler will detect, with the help of technology, when something is approaching or you are very close to it. As the object gets closer, it will beep faster and louder. When the 4-wheeler beeps really fast and really loud, it means that you are about to crash or you are in danger. It will stop and launch an airbag so you stay safe. When the 4-wheeler stops, it will make a signal to let people know that you have stopped.

I am so sorry if this wasn't the response that you were looking for.

Hope this helped!

In which environment would a forensic scientist not be found?
mrs_skeptik [129]

The correct answer is D. In a police interrogation room, questioning the suspect.

Explanation:

Forensic scientists are experts who use science as part of criminal investigations. Indeed, the main role of these experts is to deal with the evidence related to the crime to help authorities understand how the crime occurred and who was involved in this.

Because of this, the forensic scientist's role includes collecting evidence, analyzing samples, participating as witnesses in trials, and in some cases teach other experts about techniques. However, forensic scientists cannot interrogate suspects as they only deal with evidence and this process is in charge of the police.

How many milliliters of a 9.0 m h2so4 solution are needed to make 0.25 l of a 3.5 m h2so4 solution?
lorasvet [3.4K]
The rule that we will use to solve this problem is:
M2*V1 = M2*V2 where:
M1 is the initial concentration = 3.5 m
V1 is the initial volume = 0.25 l = 250 ml
M2 is the final concentration = 9 m
V2 is the final volume that we need to find

Substitute with the givens in the above equation to get V2 as follows:
3.5*250 = 9*V2
V2 = 97.2223 ml

agasfer [191]

The geometric arrangement of one of two or more compounds that have the same number and type of atoms but differ drastically from one another.

<h3>What is structural isomers?</h3>

The term "structural isomer," also known as a "constitutional isomer," refers to a group of two or more organic compounds that share the same chemical formula but have different structures. In spite of having the identical chemical formula, the two molecules below differ in where the methyl group is located.

The most extreme kind of isomerism is structural isomerism. As contrast to stereoisomerism, which merely differs in the relative spatial arrangement of the atoms while maintaining the identical atoms and bonding structure. The enantiomers, which have molecules that are mirror images of one another, and the cis and trans forms of 2-butene are examples of the latter.

Skeletal isomers, positional isomers (also known as regioisomers), functional isomers, tautomers, and structural topoisomers are some of the different classes of structural isomers.
