Show work please

Answers

Answer:

we find the mass for each element in one mole by multiplying the number of atoms in one molecule with the atomic mass

mC=8Ac=8*12=96g

mH=10AH=10*1=10g

mN=4AN=4*14=56g

mO=2AO=2*16=32g

by adding the masses together we find the molar mass of the molecule

M=mC+nH+mN+mO=96+10+56+32=194g/mole

we apply the rule of threes to find the percentage of each element

194g..96gC..10gH...56gN....32gO

100g....a...........b...........c.............d

a=(100*96)/194=49.48%C

b=(100*10)/194=5.19%H

c=(100*56)/194=28.85%N

d=(100*32)/194=16.48%O

Students are investigating the relationship between pressure and temperature in gases. They have blown up a balloon with carbon dioxide from an air tank and connected the balloon to a pressure gauge. The balloon is then submerged in ice or water baths at various temperatures in order to observe the pressure level after several minutes. What is the flaw in the student’s investigation, and how can the students improve their investigation to correctly determine the relationship?
A.
The volume and density of the air in the balloon can change, therefore they need to use several different balloons at different volumes to account for how density and volume affects pressure.

B.
The volume of the balloon can change, therefore they need to use several different balloons at different volumes to account for how volume affects pressure.

C.
The volume and density of the air in the balloon can change, therefore they need to use a rigid container such as plastic or metal to hold the air.

Answers

You come across an article in a scientific journal from 50 different laboratories around the globe that measured the boiling point of water and discovered that it is 100°C everywhere.

What transpires when water is heated to 100 C (This is 212 F)?

Water turns into gas around 212°F (100°C), which is the temperature at which it begins to boil (water vapor). Pressure affects the melting/freezing and boiling points. Water's boiling point changes when air pressure changes. The boiling point decreases with increasing altitude or decreasing pressure.

At 212 degrees Fahrenheit, does water boil, or at 100 degrees?

Water has a freezing point of 32 degrees Fahrenheit and a boiling point of 212 degrees Fahrenheit on the Fahrenheit scale.

Explanation:

UGRENT! Please help showing all work

Answers

Answer:

a. Oxygen

b. 20.39g of Al₂O₃

c. 87%

Explanation:

In order to produce 2moles of Al₂O₃, we need to make react 4 moles of Al, to 3 moles of O₂.

We determine the limiting reactant with the moles of each:

12.98g / 26.98g/mol = 0.481 moles of Al

9.6g / 32g/mol = 0.300 moles of oxygen

4 moles of Al react to 3 moles of O₂

Then, 0.481 mol may react to (0.481 . 3)/4 = 0.361 moles

We only have 0.300 moles of O₂ and we need 0.361. Oxygen is the limiting reactant.

So 3 moles of O₂ can produce 2 moles of Al₂O₃

Our 0.300 moles may produce (0.300 . 2) / 3 = 0.200 mol

Our theoretical yield is: 0.2 mol . 101.96g/ mol = 20.39 g

To determine the percent yield we calculate:

(Produced yield/ Thoeretical yield) . 100 → (17.74 /20.39) . 100 = 87%

Gas in a balloon occupies 3.3 liters. What volume will it occupy if the pressure is changed from 100 kPa to 90.0 kPa, if the temperature is held constant?

Answers

Answer:

3.7 L

Explanation:

Initial volume (V₁) = 3.3 L

Initial pressure (P₁) = 100 KPa

Final pressure (P₂) = 90 KPa

Final volume (V₂) =?

The final volume of the gas can be obtained by using the Boyle's law equation as follow:

P₁V₁ = P₂V₂

100 × 3.3 = 90 × V₂

330 = 90 × V₂

Divide both side by 90

V₂ = 330 / 90

V₂ = 3.7 L

Thus, the final volume of the gas is 3.7 L

Lutetium (Lu) is a member of the lanthanide series, which is a group of 15 elements located in the f-block of the periodic table. The lanthanide series starts with the element Lanthanum (La) and ends with Lutetium (Lu). Lutetium is the heaviest and most dense element in the lanthanide series. Lutetium has an atomic number of 71, indicating that it has 71 protons in its nucleus. It has a relatively high atomic mass of approximately 174.97 atomic mass units (u) according to the periodic table.

Hence, lutetium is the lanthanide element with the least mass.

what is nucular decay

Answers

nuclear decay is the decay of atoms on the atomic scale. “Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles or photons.”

Answer:

Nuclear decay is also called radioactive decay, and it occurs in a series of sequential reactions until a stable nucleus is reached. Nuclear reactions release much more energy—orders of magnitude more—than exothermic chemical reactions.

What are resistors? please help​

Answers

Answer:Resistor Basics

Resistors are electronic components which have a specific, never-changing electrical resistance. The resistor's resistance limits the flow of electrons through a circuit.

They are passive components, meaning they only consume power (and can't generate it). Resistors are usually added to circuits where they complement active components like op-amps, microcontrollers, and other integrated circuits. Commonly resistors are used to limit current, divide voltages, and pull-up I/O lines.

Resistor units

The electrical resistance of a resistor is measured in ohms. The symbol for an ohm is the greek capital-omega: Ω. The (somewhat roundabout) definition of 1Ω is the resistance between two points where 1 volt (1V) of applied potential energy will push 1 ampere (1A) of current.

As SI units go, larger or smaller values of ohms can be matched with a prefix like kilo-, mega-, or giga-, to make large values easier to read. It's very common to see resistors in the kilohm (kΩ) and megaohm (MΩ) range (much less common to see miliohm (mΩ) resistors). For example, a 4,700Ω resistor is equivalent to a 4.7kΩ resistor, and a 5,600,000Ω resistor can be written as 5,600kΩ or (more commonly as) 5.6MΩ.

Schematic symbol

All resistors have two terminals, one connection on each end of the resistor. When modeled on a schematic, a resistor will show up as one of these two symbols:

Resistor schematic symbols

Two common resistor schematic symbols. R1 is an American-style 1kΩ resistor, and R2 is an international-style 47kΩ resistor.

The terminals of the resistor are each of the lines extending from the squiggle (or rectangle). Those are what connect to the rest of the circuit.

The resistor circuit symbols are usually enhanced with both a resistance value and a name. The value, displayed in ohms, is obviously critical for both evaluating and actually constructing the circuit. The name of the resistor is usually an R preceding a number. Each resistor in a circuit should have a unique name/number. For example, here's a few resistors in action on a 555 timer circuit:

Answer: resistor is

Explanation:

A resistor controls the flow of the electrical current within a circuit. Resistors are made from materials like copper or carbon, which make it difficult for the electrical charges to flow through a circuit. The most common type of resistor is a carbon resistor, which is a general purpose resistor, best suited for lower-powered circuits.
