Answer:

1.03 atm

Explanation:

Primero convertimos 21 °C y 37 °C a K:

21 °C + 273.16 = 294.16 K

37 °C + 273.16 = 310.16 K

Una vez tenemos las temperaturas absolutas, podemos resolver este problema usando la ley de Gay-Lussac:

T₁P₂ = T₂P₁

En este caso:

T₁ = 294.16 K

P₂ = ?

T₂ = 310.16 K

P₁ = 0.98 atm

Colocando los datos:

294.16 K * P₂ = 310.16 K * 0.98 atm

Y despejando P₂:

P₂ = 1.03 atm

212 pb 82 is the isotope notation for iron. what is the atomic number, mass number, and number of both protons and neutrons?

o-na [289]

Hello!

The mass number in isotope notation is denoted A, the atomic number is denoted as Z, and the element is denoted as X.

In the given isotope, the mass of the isotope is 212 amu, and the atomic number is 82.

We know that the number of electrons, and protons are equal to the atomic number. Therefore, there are 82 protons. Also, to find the number of neutrons, we subtract the atomic number from the atomic mass.

212 - 82 = 130 neutrons

Final answers:

Atomic Number: 82
Mass number: 212
Number of Protons: 82
Number of Neutrons: 130

You are a researcher for a golf club manufacturer. You are given two identical looking cubes of a metal alloy. You are informed

Rashid [163]

Answer:

C.Melt both cubes and look for a broader range of melting temperatures. The one that melts over a broader range of temperatures is the amorphous solid.

Explanation:

Amorphous solids is one that do not have a fixed melting points but melt over a wide range of temperature due to the irregular shape hence its name. Contrariwise crystalline solids, have a fixed and sharp melting point.

This comes in handy to solve the riddle. We can characterise the pair with the melting point property.

I can't decide what to ship bacudeku or tododeku

iVinArrow [24]

Answer:

I would go with tododeku to leave room for kiribaku but that's my opinion

Just because I ship that doesn't mean i don't secretly ship bakudeku

Explanation:

Bakudeku is a hawt ship and I love it so friggen much, but kiribaku is kinda cute and it got me all mixed up. I'm in a mess as well trying to figure out a solid ship for each character. I'm procrastinating by drawing a bunch of random fanart.

A compound contains 1.2 g of carbon, 3.2 g of oxygen and 0.2g of hydrogen. Find the formula of the compound

Karolina [17]

Answer:

The empirical formula of the compound is $C_{0.504}HO_{1.008}$ .

Explanation:

We need to determine the empirical formula in its simplest form, where hydrogen ( $H$ ) is scaled up to a mole, since it has the molar mass, and both carbon ( $C$ ) and oxygen ( $O$ ) are also scaled up in the same magnitude. The empirical formula is of the form:

$C_{x}HO_{y}$

Where $x$ , $y$ are the number of moles of the carbon and oxygen, respectively.

The scale factor ( $r$ ), no unit, is calculated by the following formula:

$r = \frac{M_{H}}{m_{H}}$ (1)

Where:

$m_{H}$ - Mass of hydrogen, in grams.

$M_{H}$ - Molar mass of hydrogen, in grams per mole.

If we know that $M_{H} = 1.008\,\frac{g}{mol}$ and $m_{H} = 0.2\,g$ , then the scale factor is:

$r = \frac{1.008}{0.2}$

$r = 5.04$

The molar masses of carbon ( $M_{C}$ ) and oxygen ( $M_{O}$ ) are $12.011\,\frac{g}{mol}$ and $15.999\,\frac{g}{mol}$ , then, the respective numbers of moles are: ( $r = 5.04$ , $m_{C} = 1.2\,g$ , $m_{O} = 3.2\,g$ )
