A student used a sling psychrometer to measure the humidity of the air. If the relative humidity was 65% and the dry bulb temperature was 10 C, what was the dew point temperature

Answers

Answer 1

Answer:

3° C

Explanation:

The dew point temperature is the temperature of the air to which the air must be cooled so as to become saturated with the water vapor.

Here it is given that the relative humidity in the air, RH=  is 65%

And the dry bulb temperature is T = 10° C

Therefore, the dew bulb temperature is,

 [tex]$Td= T - \frac{100-RH}{5}$[/tex]

[tex]$Td= 10 - \frac{100-65}{5}$[/tex]

       = 10 - 7

       = 3° C

So the dew point temperature is 3° C .

Methanol, CH3OH, is the simplest of the alcohols. It is synthesized by the reaction of hydrogen and carbon monoxide. Write chemical reactions. If 500 mol of CO and 750 mol of H2 are present, which is the limiting reactant?

Answers

Answer:

The limiting reactant is H₂

Explanation:

The reaction of hydrogen (H₂) and carbon monoxide (CO) to produce methanol (CH₃OH) is the following:

2H₂(g) + CO(g) → CH₃OH(g)

From the balanced chemical equation, we can see that 1 mol of CO reacts wIth 2 moles of H₂. So, the stoichiometric ratio is:

2 mol H₂/1 mol CO = 2.0

We have 500 mol of CO and 750 mol of H₂, so we calculate the ratio to establish a comparison:

750 mol H₂/500 mol CO = 1.5

Since 2.0 > 1.5, we have fewer moles of H₂ than are needed to completely react with 500 moles of CO. In fact, we need 1000 moles of H₂ and we have 750 moles. So, the limiting reactant is H₂.

3. A sample of air in a syringe exerts a pressure of 1.02 atm at 22.0°C. The syringe is placed in a boiling-water bath at 100.0°C. The
pressure is increased to 1.23 atm by pushing the plunger in, which reduces the volume to 0.224ml What was the initial volume?

Answers

Answer:

0.214 mL    

explanation:

Ideal Gas law is applied to the ideal gases. The initial volume of air in the syringe when applied pressure and reducing the volume to 0.2234 mL is 0.214 mL.

What is the Ideal Gas Equation ?

The equation relating all the characteristics of a gas and behaving or assuming to be ideal is the ideal gas law equation.

pV = nRT

Here, p is the pressure, V is the volume, R is the universal gas constant, n is the number of moles and T is the temperature.

According to the law, the initial and final values of gas are related as

[tex]\dfrac{P_{1} V_{1} }{T_{1} } =\dfrac{P_{2} V_{2} }{T_{2} }[/tex]

The initial pressure P₁ is 1.02 atm and final pressure P₂ is 1.23 atm.

The  initial temperature T₁  is (22+273)=295 K and the final temperature (100+273)=373 K

The final volume  V₂ given is 0.224 mL

Placing the values into the ideal gas equation and solving, we get the value of initial volume.

V₁= 0.214 mL

The initial volume of air in the syringe when applied  pressure and   reducing the volume to 0.2234 mL is 0.224 mL.

Look at the images of Mars below. choose three features from the images and explain why they provide evidence thatt there is or was water on Mars. NEED HELP ASAP. (Will mark Brainlist)​

Answer:

Spot (4)  Has evidence that there were waves here at some point. It looks as if the sand/surface debris was moved back and forth, creating this pattern in the sand. Spots (5) and (7) show evidence of water erosion. The smooth edges of both hills mean that water once flowed through that area, carrying little pebbles and rocks that gradually shaped and smoothed those mounds. An example for this would be how there are smooth areas in the Grand Canyon where scientists have concluded that some, if not all, of the Grand Canyon was formed by flowing water.

Which change does not increase the speed of reaction between zinc and hydrochloric acid?

Answers

When solid zinc is dropped into hydrochloric acid solution, it falls to the bottom due to its higher density. The reaction occurs at the surface of the zinc metal and generates hydrogen gas that bubbles up through the solution. You can tell that the rate increases because the rate of bubble formation increases. This will naturally occur because the reaction is exothermic and will warm the solution around the zinc metal. The higher temperature will increase the reaction rate.

If you want a more quantitative analysis of reaction rate, you can perform the experiment in a eudiometer tube that is inverted and completely filled with liquid. As the hydrogen gas collects in the tube you can measure its accumulated volume with time. That will allow you to determine an approximate kinetic rate law for the process. The rate law determined in this manner will suffer from error due to temperature and surface area changes as well as gas volume error due to water vapor. But, it is an interesting application of chemical kinetics.

By adding the decreasing the temperature, the speed of the reaction will not be increased.

What is speed of the reaction ?

The reaction rate, which is a measure of how quickly reactants are consumed as well as products are created, determines the speed of a reaction.

When the temperature is lowered, the molecules move more slowly and collide less. The reaction's speed is slowed as the temperature drops.

Therefore, by adding the decreasing the temperature, the speed of the reaction will not be increased.

When acid rain enters lake water, it can be neutralized by the bases present and thus the lake does not become too acidic. Since the key ion is the hydroxide ion, the nature of the location doesn’t matter in this case. All over the world, right now, pollution workers are measuring calcium carbonate in lakes and streams.

The coefficients in a balanced chemical equation are important because they give the ratio of the reactants and the products. Those ratios are fixed and when the reagents react do it in the same proportion and yield the products in the same proportion of the coefficients. Then, the coefficients are the basis for the calculations of the amount of substances that react and the amount of substances that are formed as result of the reaction.
