Can Air can be warmed or cooled by the surface below

suter [353]

I believe it can be warm because usually the surface below us is warm itself, causing the air to be warm as well. The temperature can vary as well

In an acid-base titration, a student uses 21.35 mL of 0.150 M NaOH to neutralize 25.00 mL of H2SO4. How many moles of acid are i

GalinKa [24]

Answer: There are 0.006 moles of acid in the flask.

Explanation:

Given: $V_{1}$ = 21.35 mL, $M_{1}$ = 0.150 M

$V_{2}$ = 25.0 mL, $M_{2}$ = ?

Formula used to calculate molarity of $H_{2}SO_{4}$ is as follows.

$M_{1}V_{1} = M_{2}V_{2}$

Substitute the values into above formula as follows.

$M_{1}V_{1} = M_{2}V_{2}\\0.15 M \times 21.35 mL = M_{2} \times 25.0 mL\\M_{2} = 0.1281 M$

As molarity is the number of moles of a substance present in a liter of solution.

Total volume of solution = $V_{1} + V_{2}$

= 21.35 mL + 25.0 mL

= 46.36 mL (1 mL = 0.001 L)

= 0.04636 L

Therefore, moles of acid required are calculated as follows.

$Molarity = \frac{no. of moles}{Volume (in L)}\\0.1281 M = \frac{no. of moles}{0.04635 L}\\no. of moles = 0.006 mol$

Thus, we can conclude that there are 0.006 moles of acid in the flask.

A sample was then prepared containing 14.00 mL of coffee and 8.00 mL of 4.80 ppm Li , and diluted to a 50.00 mL total volume. Th

mafiozo [28]

Answer:

The right answer is " $[Na^+]=5.57 \ ppm$ ".

Explanation:

The given values are:

$\frac{A_s}{A_{coffee}} =\frac{0.840}{1.000}$

According to the question,

The concentration of standard will be:

= $\frac{7.80}{50.00}\times 4.80$

= $0.156\times 4.80$

= $0.748 \ ppm$

Coffee after dilution,

⇒ $\frac{A_{coffee}}{C_{coffee}} =F\times \frac{A_s}{C_s}$

or,

⇒ $C_{coffee}=\frac{A_{coffee}}{A_s}\times \frac{C_s}{F}$

On substituting the values, we get

⇒ $=\frac{1.000}{0.840}\times \frac{0.748}{1.68}$

⇒ $=1.191\times 1.3104$

⇒ $=1.561 \ ppm$

hence,

In unknown sample, the concentration of coffee will be:

= $1.561\times \frac{50}{14}$

= $\frac{78.05}{14}$

= $5.57 \ ppm$

Which of the following most likely happens when the volume of a gas increases? (4 points)

Xelga [282]

Answer:

Molecules in the gas move faster due to the fact they have more energy

Explanation:

If you put more heat the higher the volume will be. Less heat means less volume.
