Having a standard is ethical practices is important when considering experiments because it promotes the goals of the research such as the truth and knowledge. This will stop researchers from falsifying data and minimizes error in research. Research generally requires a great deal of collaboration between scientists and having a code of ethics will allow researchers to trust one another and be accountable for their work. Also, researchers need to be held accountable to the public and this can help build public support for that particular research. Ethics will also promote social and moral values, such as human and animal rights.

Calcum chloride contains only calcum and chloride What is the fomula for this compound? fou need the Peodie Table for thia quest

mafiozo [28]

Answer:

$CaCl_2$

Explanation:

Calcium is the element of the group 2 and period 4 which means that the valence electronic configuration is $[Ar]4s^2$ .

Chlorine is the element of the group 17 and period 3 which means that the valence electronic configuration is $[Ne]3s^23p^5$ .

Thus, calcium losses 2 electrons to 2 atoms of chlorine and these 2 atoms of chlorine accepts each electron to form ionic bond. This is done in order that the octet of the atoms are complete and they become stable.

Ca Cl

2 1

Cross multiplying the valency, We get, $CaCl_2$

Thus, the formula of calcium chloride is $CaCl_2$ .

What type of chemical reaction is AgNO3(aq)+KCL(aq) AgCL(s)+KNO3(aq)

emmasim [6.3K]

Answer:

double replacement reaction or double displacement reaction,

Explanation:

double replacement reaction, double displacement reaction, is a chemical process involving the exchange of bonds between two non-reacting chemical species which results in the creation of products with similar or identical bonding affiliations

Classically, these reactions result in the precipitation of one product.

in thía case it is AgCl

A bus traveled south west for 422 kilometers. The entire trip took 3 hours. Calculate the velocity.

ahrayia [7]

V= d/t
v=speed
d=distance
t=time

So v= 422/3
v =140.667m/s

1. a. FeS + 2HCl --> FeCl2 + H2S
b. This is a double- replacement reaction. (The elements "switch partners".)

2. a.2Na + F2 --> 2NaF
b. This is a composition/synthesis reaction. (The two reactants are combining or synthesizing to make one product.)

3. a. 2HgO --> 2Hg + O2
b. This is a decomposition reaction. (The single reactant is breaking down or "decomposing" into multiple reactants.)

4. Hydrogen gas reacts with oxygen gas to create water in a composition/synthesis reaction.

I hope these answers will help you! If you need any explanation, ask and hopefully I can get back to you. ;)

The quantity, 1,385 mg is equivalent to in scientific notation

Agata [3.3K]

Answer:

The answer is 1385 x10∧ -3

Explanation:

Scientific notation is a quick way to represent a number using notation in exponential form or powers of base ten.

This notation allows us to express too large or small numbers easily.

<u>For example: </u>

500 is written as 5x10∧2; Where the power 2 represents the number of 0's that follow 5.

0.0093 is written as 9.3x10∧-3; Where the power -3 represents the number of times the comma was moved to the right.
