A 250 mL beaker is submerged in a large container of Liquid X and turned upside down, and another 250 mL beaker is submerged and

turned upside down in a large container of Liquid Y. Hydrogen (H2) gas is bubbled into each upside-down beaker until 100 mL of liquid has been displaced. The masses m X and my of hydrogen inside each beaker is then chemically determined.
a. mx will be greater than my
b. m x will be less than my
c. mx will be equal to my
d. It's impossible to predict whether mx or my will be greater without more information.

Answer:

Mx will be less than My.

Explanation:

The correct option is - Mx will be less than My.

Because, liquid X have been higher viscosity and vapor pressure than liquid B.

Vapor pressure of liquid A is greater, so the amount of liquid X will vaporized greater and H2 gas has been displaced greater from the beaker as compared to liquid Y.

The amount of H2 in liquid Y remains greater in beaker as compared to liquid X.

So, Mx will be less than My.

Answer : 4.8 florins can you exchange for your 4 guilders.

Solution : Given,

The current exchange rate for every 2.4 florins is 2.0 guilders

As per question,

The exchange rate is 2.0 guilders for every 2.4 florins

The exchange rate is 1 guilders for every \frac{2.4}{2.0} florins

The exchange rate is 4 guilders for every \frac{2.4}{2.0}\times 4=4.8 florins

Therefore, the 4.8 florins can you exchange for your 4 guilders.

A drug is supplied as a 40 mg/ml solution in a 50 ml vial. you need to make 10 ml of a 10 mg/ml solution. how much concentrate w
Ymorist [56]

Answer: -

2.5 mL

Explanation: -

Volume of final solution = 10 mL

Strength of final solution = 10 mg / mL

Amount of drug required = Volume of final solution x strength of final solution

= 10 mL x 10 mg/ mL

= 100 mg.

Strength of supplied drug = 40mg/ mL

Volume of supplied drug required = \frac{100 mg}{40 mg/ mL}

= 2.5 mL

Thus to make 10 ml of a 10 mg/ml solution. 2.5 mL will be needed.

Given the following proposed mechanism, predict the rate law for the rate-determining step.
PilotLPTM [1.2K]

Answer:

D) Rate = K [NO2][Cl2]

Explanation:

2 NO2 + Cl2 → 2 NO2Cl (overall reaction)

NO2 + Cl2 → NO2Cl + Cl (slow)

NO2 + Cl → NO2Cl (fast)

The rate-determining step is the slowest step in a reaction mechanism. Because it is the slowest, it determines the rate of the overall reaction.

Rate of reaction is typically given as;

Rate = K [Reactants]

In the slow step i the reaction mechanism, the reactants are; NO2 and Cl2. Since both are not intermediates, there is no need for further working out.

Rate = K [NO2][Cl2]

You stir a cup of hot chocolate with a spoon. Why does the spoon keep its shape in the drink?
luda_lava [24]

a because the spoon is a solid and the hot chocolate is a liquid.So that means that spoon moves slower than a liquid.
