These days, scientists all over the world use a standard system of measurements. It's the SI or metric system.

What about scientists in the United States, Liberia, and Burma ? These three countries are the only ones in the world that haven't adopted the metric system. What do THEY do ?Easy. When scientists in those countries are off work, they use the inches, yards, feet, quarts, miles and gallons that everybody around them is using. But when they go to work, they use the same metric system that everyone else in the world is using.

IF THE FIRST ONE DOESN'T WORK TRY THE SECOND

1. They use the same measuring system (metric)2. Clearly and properly collect and record data, recording the procedure and results3. Releasing the data into the public, letting everyone have access to it

Two atoms that are isotopes of one another must have the same number of what? Electrons, All Particles, Protons, or Neutrons

emmainna [20.7K]

atoms are made of 3 types of sub atomic particles; neutrons, protons and electrons

atomic number is the number of protons which is characteristic for the element. Atoms of the same element have the same number of protons.

mass number is the sum of the neutrons and protons.

Isotopes are atoms of the same element with different mass numbers. since they are the same element number of protons are the same but number of neutrons vary.

therefore 2 isotopes are of the same element so they have the same number of protons.

Which term best describes this reaction? 2 carbons double bonded to each other, with CH 3 above the left C and H above the right

Ierofanga [76]

Answer:

addition polymerization

Explanation:

In addition polymerization, the monomers are simply joined to each other to form a polymer having the same empirical formula as the monomer but of higher relative molecular mass. The monomers in addition polymerization are usually simple unsaturated molecules such as alkenes.

We can deduce the reaction to be an addition polymerization because of the the attachment of n to both the unsaturated monomer and the saturated polymer without the loss of any small molecule. If it was a condensation polymerization, there would have been an accompanying loss of a small molecule such as water.

On a summer day, you take a road trip through Chelan, WA, in a Tesla Model S. You start out at a temperature of 19°C in the morn

ASHA 777 [7]

1. 1.636 moles

2. 271.06 kPa pressure

3. Tires will be burst

4. 235.91 kPa

Explanation:

Step 1:

PV = nRT, is the equation to be used where

P represents pressure

V represents volume

n represents moles of gas

R is constant

T represents temperature in Kelvin

n=RT/PV

It is given that the pressure is 245 kPa at initial temperature 19 C and tire volume is 16.2 L. Temperature must be converted to Kelvin, 19 C equals 292K.

n=PV/RT ->245*16.2/(8.31*292) = 1.636

Number of moles of Nitrogen in the tire = 1.636

Step 2:

We need to find the maximum tire pressure at 50 C (323K)

P = nRT/V

Substituting the values P = (1.636 * 8.31 * 323)/16.2 = 271.06 kPa

The tire pressure at 50 C will be 271.06 kPa

Step 3

We need to figure out if the tires would burst in Chelan when the temperature is 55 C. It is given that the maximum pressure the tires can withstand is 265 kPA, so any pressure above this will cause the tire to burst. In Step-2 we calculated that the pressure is 271.06 kPA at 50 C which is more than the maximum pressure the tire can withstand. The pressure would increase further with temperature and at 55 C the pressure will be more than 271.06 kPa. So the tires are likely to burst in Chelan.

Step 4:

We need to find the pressure of Nitrogen at 19 C before the start of the trip so that tires will not burst. The pressure at 55 C is 265 kPa. Let us find the number of moles at this temperature and pressure.

n= PV/RT -> n=265*16.2/(8.31*328) = 1.575

Now let us find the pressure at 19 C.

P = nRT/V -> 1.575*8.31*292/16.2 = 235.91 kPa
