Imagine you are taking a road trip! Select a destination and navigate the trip. Answer the following questions in one or more co

mplete sentences: Where will you go on your trip? You approach a railroad crossing with a cross buck sign that has no lights or gates. What should you do? You arrive at an intersection with traffic lights that are not working because of a power outage. What do you do? There is a flashing yellow light at the intersection you are approaching. What does the flashing yellow light indicate, and what should you do to safely navigate this intersection? On the road you are traveling, the pavement markings change from broken white lines to solid white lines between the lanes of traffic. What does the line change mean? After an hour on the expressway, your passengers need to use the restroom and they want to get some food. As you approach the next exit, what color sign will you look for, and what type of information would you expect to see on that sign? When you take the exit ramp off the expressway and merge onto the next road, you see yellow lines dividing the roadway. What do the yellow lines tell you about the traffic flow?

I would go to cape coral to play basketball!

1. Wait to see if it is all clear and then go

2. Yield to those coming towards you and once it is totally clear then go.

3. Means you are able to go once you yield to oncoming traffic.

4. I don't remember.

5. Well honestly all the signs here are green so! but I would look to see if it says what restraunts there are or gas stations.

What type of forces, intramolecular or intermolecular:
KIM [24]

When liquid water evaporates, its composition remains the same. The environment has an impact on the intermolecular forces, but the chemical intramolecular forces within the water molecule are unaffected.

<h3>What are intramolecular and intermolecular forces?</h3>

Three states of water have the same chemical behavior as two HH atoms bonded to one OO atom because intramolecular interactions exist within (within) the molecule. When intramolecular forces are broken, the substance's identity might be changed.

The physical behavior of the matter varies depending on its condition as the strength fluctuates from one state to another due to the intermolecular forces that exist between (outside) the molecules (kinetic and potential energy). We do not alter the composition of the substance when the intermolecular interactions are broken.

Theoretically, how much zinc [At. Wt. = 65.41] in grams would be needed to produce 500.00 grams of copper metal from any soluble
dsp73
<h3>Answer:</h3>

514.65 g of Zn

<h3>Explanation:</h3>

Zinc metal reacts with copper ions in a salt of copper to form copper metal and zinc (ii) salt.

The equation for the reaction is;

Zn(s) + Cu²⁺(aq) → Zn²⁺(aq) + Cu(s)

we are required to calculate the mass of Zinc needed

<h3>Step 1: Number of moles of copper</h3>

The mass of copper metal produced is 500.0 grams

We can get the number of moles of copper,

Molar mass of copper = 63.55 g/mol

But; Number of moles = Mass ÷ Molar mass

Therefore;

Moles of copper = 500.0 g ÷ 63.55 g/mol

                           = 7.868 moles

<h3>Step 2: Moles of Zinc </h3>

From the reaction 1 mole of Zinc metal reacts with a salt of copper (ii) to produce 1 mole of copper.

Therefore, the ratio of Zn : Cu is 1 : 1

Hence;

Moles of zinc will be 7.868 moles

<h3>Step 3: Mass of Zinc metal </h3>

Moles of Zn = 7.868 moles

Molar mass of Zn = 65.41 g/mol

But; Mass = number of moles × molar mass

Thus;

Mass of Zn = 7.868 moles × 65.41 g/mol

                  = 514.65 g

Therefore, the mass of Zn metal needed is 514.65 g

3. If 45.0 mL of 0.560 M KOH are needed to neutralize 125 mL of HCl of unknown concentration, what is
vlada-n [284]

Answer:

Molarity = 0.202 M

7.36 g/L HCl

Explanation:

KOH                        +                  HCl ----> KCl  +  H2O

1 mol                                           1 mol

0.560mol/L *0.045L                 x mol/L*0.125L

0.560mol/L *0.045L    =   x mol/L*0.125L

x = 0.560mol/L *0.045L  /0.125L= 0.2016 mol/L≈ 0.202 mol/L=0.202M HCl

M(HCl) = 1.0+35.5 = 36.5 g/mol

0.2016 mol/L*36.5 g/mol ≈ 7.36 g/L HCl

The molecular formula for caffeine is C8H10N4O2. Which of the following elements is not found in caffeine?
ANTONII [103]

The correct answer is:

b: Heluim

Explanation:

The caffeine contains: carbon , nitrogen , oxygen , hydrogen.

Caffeine is a primary nervous system energizer of the methylxanthine class. It is the world's most universally consumed psychoactive drug. Unlike many other psychoactive elements, it is fair and unlimited in nearly all parts of the world. Caffeine can be arranged as an alkaloid, a term used for substances originated as end results of nitrogen metabolism in some plants.
