How do ethical guidelines make science safer ?

Chemistry

Explanation:

ethical guidelines are made to be implemented together to make any type of ethical judgment.

ethical guidelines make science safer because

  • It provides restrictions to the scientist, they can't claim their results, which may be inaccurate or would cause any harm to the surroundings and society.
  • As per the Ethical guidelines, researchers are allowed to follow certain rules while conducting out research, so that their work does not cause any harm to the environment and participants.

Well, for one thing, they ensure that a scientist can't claim a certain result, which might be biased and thus inaccurate, because he or she is being paid by, say, big business interests. For another, they ensure that medicines or treatments can't be made available to the public without thorough testing, replication, and peer review.

Complete combustion of 8.10 g of a hydrocarbon produced 25.9 g of CO2 and 9.27 g of H2O. What is the empirical formula for the h
balu736 [363]

CxHy     +  O2    -->    x CO2     +    y/2  H2O

 

Find the moles of CO2 :     18.9g  /  44 g/mol   =    .430 mol CO2   = .430 mol of C in compound

Find the moles of H2O:      5.79g / 18 g/mol     =     .322 mol H2O   = .166 mol of H in compound

 

Find the mass of C and H in the compound:

                             .430mol  x 12  =  5.16 g C

                              .166mol  x 1g   = .166g H   

 

When you add these up they indicate a mass of 5.33 g for the compound, not 5.80g as you stated in the problem.

Therefore it is likely that either the mass of the CO2 or the mass of H20 produced is incorrect (most likely a typo).

In any event, to find the formula, you would take the moles of C and H and convert to a whole number ratio (this is usually done by dividing both of them by the smaller value).

Complete them with correct formulas<br> Then balance them
otez555 [7]

Answer:

1. 2Ca + N_{2} → 2CaN

2. 4Li + O_{2} → 2Li_{2}O

3. 2KCl + BaF_2 → 2KF + BaCl_2

4. CH_4 + 2O_2 → CO_2 + 2H_2O

Be sure to balance the number of atoms on both sides of each equation only by adding coefficients to the compounds!!!! Those without a coefficient are meant to have a coefficient of 1.

Used to describe an atom’s ability to chemically bond with another atom
zepelin [54]

Answer:

"Electronegativity" is the atom's ability to chemically bond with another atom.

Explanation:

Electronegativity is the ability of the atom to attract the electrons towards another atom to it, these two atoms are associated through a bond. The phenomena is based on the atom's ionization energy and the electron affinity. The formation of the chemical bond takes place when the atoms share the electrons they have in outer shells. In other words we can say two atoms fuse together to form chemical bond.

For the chemical reaction
kakasveta [241]

Answer:

Mass = 199.21 g

Explanation:

Given data:

Moles of HCl = 3.59 mol

Mass of CaCl₂ = ?

Solution:

Chemical equation:

2HCl + Ca(OH)₂  →     CaCl₂ + 2H₂O

we will compare the moles of HCl with  CaCl₂ from balanced chemical equation:

                HCl             :           CaCl₂

                   2              :              1

                 3.59           :             1/2×3.59 = 1.795  

3.59 moles of HCl will produced 1.795 moles of CaCl₂.

Mass of CaCl₂.

Mass = number of moles × molar mass

Mass = 1.795 mol  × 110.98 g/mol

Mass = 199.21 g
