Answer: The correct answer is option (A).

Explanation:

Polar molecules are molecules in which formation of partial charges takes place due to which dipole moment gets created in a molecule. Molecules with polar bonds that s bond with partly ionic character. And water is of the example of polar molecule.

Electronegative oxygen atom in water molecule attracts the electron bond pair towards itself which generates partial negative charge on oxygen atom and partial positive charge on both hydrogen atoms.

Where as water has higher value surface tension due to strong intermolecular association of the water molecule due to presence of hydrogen bonding.And it is more denser is liquid state than in its solid state.

Hence,the correct answer is option (A).

Please help me, I’m stuck on this question

zubka84 [21]

Answer:

$\large \boxed{\text{0.0820 L$\cdot$atm$\cdot$K$^{-1}$mol}^{-1 }}$

Explanation:

To solve this problem, we can use the Ideal Gas Law:

pV = nRT

Data:

p = 3.00 atm

V = 17.4 L

n = 2.00 mol

T = 45 °C

Calculations:

1. Convert the temperature to kelvins

T = (45 + 273.15) K = 318.15 K

2. Calculate the value of R

$\begin{array}{rcl}pV & = & nRT\\\text{3.00 atm} \times \text{17.4 L} & = & \text{2.00 mol} \times R \times \text{318.15 K}\\\text{52.2 L$\cdot$atm} & = & 636.30R \text{ K$\cdot$mol}\\R & = & \dfrac{\text{52.2 L$\cdot$atm}}{636.30 \text{ K$\cdot$mol}}\\\\ & = & \textbf{0.0820 L$\cdot$atm$\cdot$K$^{-1}$mol}^{-1} \\\end{array}\\\text{The value of the gas constant R is $\large \boxed{\textbf{0.0820 L$\cdot$atm$\cdot$K$^{-1}$mol}^{-1 }}$}$

The rate of reaction (reaction rate) is the

Lorico [155]

Sugar dissolves faster in a warm liquid than in a cold liquid – this is an example of how temperature influences the reaction rate....

Yes it is. Another example is surface area of reactants, powdered iron fillings would react faster in HCl than iron lumps.

Also your beverage would also dissolve faster in hot water than in cold water, this is also an example of how temperature affects rate of reaction.

There are other examples that can be stated as well.

How many atoms does Iron oxide have?

ArbitrLikvidat [17]

Added together = 159.7 grams for one mole of Fe2O3. That is moles of hematite, but the question is about iron. We can see there are two iron atoms for every hematite molecule. So the number (moles) of iron atoms is twice the moles of the hematite molecules.

so depending on how much you initially have will determine the answer
