<span>Two scientists wrote a paper detailing their research and conclusions and submitted it to a scientific journal. Several months later, they received the paper back from the publisher with many comments attached from several fellow scientists. It is either that they revise their study or replicate the study. Most scientists would revisit their work and the findings they had from their research. Most probable if they were successful and the comments of the publisher and the co-scientists were positive they could replicate the study to validate its accountability.<span>

What is the mass, in grams, of 1.26 mol of water, H2O?
Masteriza [31]

Answer:

The mass of 1.26 mole of water, H₂O, is 22.68 grams

Explanation:

Molar mass is the amount of mass that a substance contains in one mole. In other words, the molar mass of an atom or a molecule is the mass of one mole of that particle and its unit is g/mole.

In this case, being:

  • H: 1 g/mole
  • O: 16 g/mole

the molar mass of water H₂O is:

H₂O= 2*1 g/mole + 16 g/mole= 18 g/mole

Then you can apply the following rule of three: if 18 grams are present in 1 mole of H2O, how much mass is present in 1.26 moles of water?

mass=\frac{1.26 moles*18 grams}{1 mole}

mass= 22.68 grams

<u><em>The mass of 1.26 mole of water, H₂O, is 22.68 grams</em></u>

Carbon disulfide burns in oxygen to yield car- bon dioxide and sulfur dioxide according to the chemical equation cs2(l) 3 o2(g)
vampirchik [111]

Answer: Oxygen is the limiting reagent.

Explanation: CS_2(l)+3O_2(g)\rightarrow CO_2(g)+2SO_2(g)

As can be seen from the given balanced equation:

3 moles of O_2 reacts with 1 mole of CS_2

1.52 moles of O_2 reacts with=\frac{1}{3}\times 1.52=0.51moles of CS_2

Thus O_2 is the limiting reagent as it limits the formation of products. (0.91-0.51)= 0.40 moles of CS_2 will remain as such and thus  CS_2 is an excess reagent.

All magnetic minerals will have the element iron in the chemical composition true or false
Margaret [11]

The statement is true. If a mineral lacks the presence of iron in it then it will be generally dimagnetic.  It means non iron minerals do not show magnetic property in general. There are some minerals like serpentine do show some magnetic susceptibility, however this is negligible as compared to iron minerals hence the ores with no magnetic are generally diamagnetic.

Indicate whether each of the statements below is true or false. 1. CBr4 is more volatile than CCl4. 2. CBr4 has a higher vapor p
Rashid [163]

Answer:

1. False

2. False

3. True

4. False

Explanation:

1. CBr4 is more volatile than CCl4  False

The molecular weight of CBr4 is is greater than the CCl4,  therefore it has less tendency to escape to the gas phase. Also, the CBr4 has greater London dispersion forces compared to CCl4 since bromine is a larger atom than chlorine.

2. CBr4 has a higher vapor pressure at the same temperature than CCl4 False

For the same reasons as above,  the vapor pressure of CBr4 is smaller than the vapor pressure of CCl4

3. CBr4 has a higher boling point than CCl4 True

Again, CBr4 having a molecular weight greater than CCl4  ( 331  g/mol vs 158.2 g/mol) is heavier and less volatile with a higher boiling point than CCl4.

4. CBr4 has weaker intermolecular forces than CCl4 False

Both molecules are non-polar because the dipole moments in C-Cl and C-Br bonds cancel in the tetrahedron. The only possible molecular forces are of the London dispersion  type which are temporary  and greater for larger atoms.
