G the hydrogen generated in this lab was a product of the reaction between magnesium and hydrochloric acid. which of these react

Colt1911 [192]

The limiting reactant is determined by the supply and stoichiometric equation.

<h3>Limiting reactants</h3>

They are reactants that are limited in availability, and thus, determine how far reactions can go in terms of producing products.

In a reaction involving magnesium and hydrochloric acid to produce hydrogen gas as follows:

$Mg + 2HCl --- > MgCl_2 + H_2$

The number of moles of HCl is twice that of Mg. Thus, if both reactants are supplied in the required proportion, no reactant will be limiting.

However, if the number of moles of HCl supplied is not up to twice that of Mg, HCl will become limiting. Also, if the amount of Mg supplied is not equal to half of that of HCl supplied, Mg will be limiting.

Solid lithium hydroxide is used to "scrub" CO2 from the air inspacecraft and submarines; it reacts with the CO2 to produce lithi

ArbitrLikvidat [17]

Answer:

223 L

Explanation:

Step 1: Write the balanced equation.

2 LiOH + CO₂ = Li₂CO₃ + H₂O

Step 2: Calculate the moles corresponding to 440 g of LiOH

The molar mass of LiOH is 23.95 g/mol.

440 g × (1 mol/23.95 g) = 18.4 mol

Step 3: Calculate the moles of CO₂ that react with 18.4 moles of LiOH

The molar ratio of LiOH to CO₂ is 2:1. The reacting moles of CO₂ are 1/2 × 18.4 mol = 9.20 mol.

Step 4: Convert 20°C to Kelvin

K = °C + 273.15 = 20 + 273.15 = 293 K

Step 5: Convert 753 torr to atm

753 torr × (1 atm/760 torr) = 0.991 atm

Step 6: Calculate the volume of CO₂

We will use the ideal gas equation.

P × V = n × R × T

V = n × R × T / P

V = 9.20 mol × (0.0821 atm.L/mol.K) × 293 K / 0.991 atm

V = 223 L

Convert a speed of 141 mi/h to units of feet per minute show work.

ozzi

Answer:

12408 feet per minute

Explanation:

Given: Speed is 141 mi/h

To find: speed in units of feet per minute

Solution:

Use the following units to convert the given speed into feet per minute.

1 mile = 5280 foot

1 h = 60 minutes

Therefore,

141 mi/h $=\frac{141(5280)}{60} =12408$ feet per minute.

[ 6.5 ] In the space below, briefly explain why the average times for the two CO2 molecules you calculated should have been simi

julsineya [31]

Answer:

This question is incomplete

Explanation:

This question is incomplete but there are two parts to this question that can generally be answered without the missing parts.

(1) If a CO₂ molecule starts out surrounded by other CO₂ molecules, does this influence how quickly it will reach the other side of the leaf?

What controls how quickly a CO₂ molecule/molecules enter into the leaf to the other parts of a leaf is the stomata on the leaf. Stomata are tiny openings on a plant leaf that allows for gaseous exchange (the release of oxygen and the absorption of CO₂) in the leaf.

(2) Collisions influence how molecules move, but do molecules only collide with other molecules of the same substance? NO

One of the kinetic theory of gases states that gases collide with one another and against the walls of the container. <u>It should however be noted that, gas molecules of a particular substance can collide with gas molecules of other substances</u>, so far they are within the same container.

What do the conclusions tell about the experiment?

Blababa [14]

Answer:

Option C

Explanation:

When you perform a experiment to test your hypothesis (your educated guess on what you think will happen) you complete trials to find data that is reliable and valid so you are only getting the best possible results. After you complete the experiment you write your conclusion which is when you take the data and you say if the data supported your hypothesis, if you did guess correctly at the beginning of the experiment. Which means the answer is option C "the conclusions tell why the data support or reject the hypothesis."

Hope this helps.
