B. dissolve at the same rate in both glasses
C.dissolve faster in the tea being stirred
D. not dissolve because stirring forms colloids

Answers

It is C. dissolve faster in the tea being stirred.

The answer is C. dissolve faster in the tea being stirred.

Stirring helps up in the speeding up of the process of dissolving.
Other factor is temperature. As temperature increases, its rate increases.

How does bias in the data affect experimental results?A. Bias makes the data harder to analyze.
B. Bias makes the results less reliable.
C. Bias makes the results easier to interpret.
D. Bias makes the results not publishable.

Answers

Answer:

Explanation:

Bias may make one side look worse than they actually are.

If you have bias data result, then you can’t trust on your outcome to be 100% accurate. So, your answer is B.

The gases listed are at standard temperature and pressure: · 1 mol of CO2 gas · 1 mol of N2 gas · 2 mol of O2 gas Which statement is correct? The volume of 1 mol of CO2 is greater than that of 2 mol of O2 . The volume of 1 mol of CO2 is greater than that of 1 mol of N2 . The volumes of 2 mol of O2 and 1 mol of N2 gases are the same. **The volumes of 1 mol of CO2 and 1 mol of N2 gases are the same.**

Answers

Answer : The volume of 1 mole of $CO_(2)$ and $N_(2)$ gases are the same.

Solution: Given,

Moles of $CO_(2)$ = 1 mole

Moles of $N_(2)$ = 1 mole

Moles of $O_(2)$ = 2 mole

Formula used for ideal gas is :

P V = n R T

According to the question, the gases are at standard temperature and pressure. So, the volume of gases only depends on the number of moles. This means that the higher the number of moles, higher will be the volume of gas.

The moles of $O_(2)$ are more than the moles of $CO_(2)$ and $N_(2)$ . So, the volume of $O_(2)$ will be more.

And the moles of $CO_(2)$ and $N_(2)$ are equal. Therefore, their volumes are also equal.

Therefore, the best option is the volume of 1 mole of $CO_(2)$ and $N_(2)$ gases are the same.

The right answer for the question that is being asked and shown above is that: "The volumes of 1 mol of CO2 and 1 mol of N2 gases are the same." The statement that is correct as far as the gases listed are at standard temperature and pressure is concerned is that the volumes of 1 mol of CO2 and 1 mol of N2 gases are the same

Which of the following cannot pass across the placenta?(a) oxygen
(b) waste materials
(c) blood
(d) nutrients

Answers

The placenta is the structure that allows for transfer of wastes, oxygen, and
nutrients between the mother and the fetus. The fetal blood comes extremely
close to the maternal blood in the placenta, but there is no intermingling of fetal
and maternal blood. The fetus and mother can even have, and often do have,
different blood types.

Oxygen cannot pass through the placenta

Which of the following molecules contains a covalent bond? (Use the electronegativity values from the periodic table link to help you answer this question.)A. HF
B. LiCl
C. CN-
D. MgO.)

Answers

If the electronegativity difference is less than 1.6 or when the difference is 1.6 - 2.0 and it only involves nonmetal, then the molecule contains a covalent bond.
A. HF: 4.0 - 2.1 = 1.9 (Covalent)
B. LiCl: 3.16 - 0.96 = 2.2 (Non-covalent)
C. CN-: 3.04 - 2.65 = 0.39 (Covalent)
D. MgO: 3.44 - 1.31 = 2.13 (Non-covalent)

Explanation:

The compound NaOH(s) dissolves in water to yield(1) hydroxide ions as the only negative ions
(2) hydroxide ions as the only positive ions
(3) hydronium ions as the only negative ions
(4) hydronium ions as the only positive ions

Answers

Answer: Option (1) is the correct answer.

Explanation:

Sodium hydroxide is a strong base and when it is dissolved in water it completely dissociates into ions.

The chemical equation for this dissociation is as follows.

$NaOH(s) + H_(2)O(l) \rightarrow Na^(+)(aq) + OH^(-)(aq)$

Therefore, we can see that sodium ions are the only positive ions and hydroxide ions are the only negative ions formed upon dissociation of NaOH in water.

Thus, we can conclude that the compound NaOH(s) dissolves in water to yield hydroxide ions as the only negative ions.
