If we put 1g samples of all four of these into a hot oven, which would absorb the most heat in order to reach 100 degrees Celsius?

Answer:

Wet climates obviously have more water than driers climates. Metals, when subject to water have the tendency to oxidize rust. Therefore, if water is barely present in a climate, then oxidation is also least likely to occur.

Answer:

.315mol CsI

Explanation:

CsI has a molar mass of 260 g/mol. This means that one mole of cesium iodide has a mass of 260 grams. We can use stoichiometry/dimensional analysis to figure out how many moles is equal to 82 grams.

[tex]82.0g CsI (\frac{1 mole}{260g} ) = .315mol CsI[/tex]

Answer:

A. V2=P1V1/P2

Explanation:

Robert Boyle law stated that pressure of a particular quantity of basis inversely varies with respect to the volume provided that the temperature is constant. It is expressed as

PiV1 = P2V2,

Where

V2= final volume

V1= initial volume

P1= initial pressure

P2= final pressure

Making V2 subject of formula we have

V2=P1V1/P2

Answer:

[tex]m_{CO_2}=1.27gCO_2[/tex]

Explanation:

Hello!

In this case, since the combustion of butane is shown below:

[tex]C_4H_{10}+\frac{13}{2} O_2\rightarrow 4CO_2+5H_2O[/tex]

We can evidence the 1:4 and 13/2:4 mole ratio of butane to carbon dioxide and oxygen to carbon dioxide respectively. Thus, in order to compute the maximum amount of carbon dioxide produced in this reaction, we set up the following stoichiometric work:

[tex]m_{CO_2}^{by\ C_4H_{10}}=4.00gC_4H_{10}*\frac{1molC_4H_{10}}{58.12gC_4H_{10}}*\frac{4molCO_2}{1molC_4H_{10}}*\frac{44.01gCO_2}{1molCO_2}=12.11gCO_2\\\\ m_{CO_2}^{by\ O_2}=1.50gO_2*\frac{1molO_2}{32gO_2}*\frac{4molCO_2}{13/2molO_2}*\frac{44.01gCO_2}{1molCO_2}=1.27gCO_2[/tex]

Thus, since oxygen yields the fewest amount of carbon dioxide, we infer the former is the limiting reactant and therefore the maximum amount of carbon dioxide product is 1.27 g.

Best regards!

Answer:

33

Explanation: first change the temperature in degree celcius to kelvin by adding 273 to 215 which makes 488 then input value into the formula pv=nrt p*75=62*0.08206*488 then divide both sides by 75 you get 33

The pressure of gas in the atmosphere is equal to 33.1 atm.

The ideal gas law can be described as an equation of the state of a hypothetical ideal gas. This law states that the multiplication of the volume and pressure of one gram molecule of an ideal gas is equal to the product of the gas constant and absolute temperature.

The mathematical equation of the ideal gas law can be written as:

PV = nRT

where V is the volume, P is the pressure, n is the amount of substance and R is the gas constant.

Given the volume of the gas, V = 71 L

The number of moles of gas, n = 62

The temperature, T = 215 °C = 273 + 215 = 488 K

The value of the universal gas constant, R = 0.082 atm L/K mol

After substituting the all values in the ideal gas equation, we get:

P × 71 = 62 × 0.082 × 488

P = 33.1 atm

Answer:

Explanation:

Answer:

Three ways that I would make most of this situation are going near an area to avoid the things drifting into space. I would seek shelter in a basement. I would also stay indoors.

Earth's atmosphere and its oceans, rivers, and lakes would be one of the first things to drift away into space, we would need to avoid those obstacles by seeking shelter. The first problem is that Earth is rotating at high speed, rather like the way a weight on a string rotates if you spin it around your head. Anyone unfortunate enough to be outside at the time would quickly be lost. People inside buildings would be safer because most buildings are so firmly rooted to the ground that they would stay put even without gravity – at least for a while.

Gravity is the universal force that attracts matter. If there is less gravity, then the objects on the Earth will become weightless.

Gravity or the gravitational force is the fundamental force present in the universe that keeps the matter attracted to each other. It plays a major role in the rotation of the earth around the sun and keeps the atmosphere of the planet balanced.

In case of no gravity, the objects will become weightless and will start to float, and Earth will stop rotating and will collide with the sun. Also, the moon will collide with the earth and the objects will perish in the universe.

Explanation:

nobel + ium = nobelium

An element named after Alfred Nobel who established Nobel prizes is Nobelium .

It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.There are 118 elements which are confirmed to exist naturally or artificially.

From solutions that evaporate

From hot water solutions when the solution cools

Explanation:

The substances that can form minerals can be dissolved in the water to form a solution. Solution can be described as as a mixture in which a solute is dissolved in a solvent. When a particular dissolved solute evaporates from the solution, crystals of minerals might form. The mineral halite was formed when seas evaporated over a period of time.

The minerals can also be formed when a hot water solution gets cooled.

Explanation:

Density is equal to mass divided by volume.

You can find the mass of the rock using the triple beam balance.

You can find the volume of the rock by pouring water from the beaker into the graduated cylinder, and seeing how much the volume of water in the cylinder changes. This change is the volume of the rock. For example, if you pour 50mL into the cylinder, add the rock, and see the new volume is 53mL, then the rock has a volume of 3mL or 3cm^3 (because one milliliter is equal to one cubic centimeter).

Then, divide the mass of the rock by the volume of the rock.
