The distance of star Betelgeuse = 325 light years

Therefore, if it where to explode, at the location, we would have a supernovae such that the luminosity of the star multiplies several multiple times

However, due to the distance of Betelgeuse from the Earth, it will take the light of the explosion, 325 years to reach Earth and the explosion as it happens will not be noticed here on Earth immediately

Answer: The partial pressure of the dry gas is 599.8 torr

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

[tex]p_{total}=p_{dry gas}+p_{H_2O}[/tex]

Given : [tex]p_{total}[/tex] =total pressure of gases = 642 torr

[tex]p_{dry gas}[/tex] = partial pressure of dry gas = ?

[tex]p_{H_2O}[/tex] = partial pressure of water = 42.2 torr

putting in the values we get:

[tex]642torr=p_{\text {dry gas}}+42.2torr[/tex]  

[tex]p_{\text {dry gas}}=599.8torr[/tex]

Thus the partial pressure of the dry gas is 599.8 torr

Scientists develop knowledge by making observation about the natural world that may lead to a scientific question.

A scientific question may lead to a(n) hypothesis which can be tested.

The results of experimentation can lead to changes in scientific knowledge.

Explanation:

In the process of developing scientific knowledge, scientists carry out series of observations on what happens in the natural world. This helps them to develop scientific questions. These scientific questions drawn can then lead to hypotheses which are testable.

The testing process leads to experimentation. It is in this process that much scientific questions receive answers. Testing actually lies at the core of scientific inquiry for all scientists. Whatever hypothesis made must always be tested.

The result of the testing or experimentation brings changes in scientific knowledge.

By adding the decreasing the temperature, the speed of the reaction will not be increased.

The reaction rate, which is a measure of how quickly reactants are consumed as well as products are created, determines the speed of a reaction.

When the temperature is lowered, the molecules move more slowly and collide less. The reaction's speed is slowed as the temperature drops.

Therefore, by adding the decreasing the temperature, the speed of the reaction will not be increased.

Answer:

533.12 L

Explanation:

The balanced chemical equation for the decomposition of CaCO₃ is the following:

CaCO₃(s) → CaO(s) + CO₂(g)

According to the equation, 1 mol of CaCO₃ produces 1 mol of gas (CO₂). We convert the moles of CaCO₃ to mass in grams with the molar mass of the compound:

molar mass CaCO₃ = 40 g/mol Ca + 12 g/mol C + (3 x 16 g/mol O)= 100 g/mol

mass of CaCO₃ = 1 mol x 100 g/mol = 100 g CaCO₃

Now, we know that 1 mol of any gas at STP occupies a volume of 22.4 L:

1 mol CO₂ = 22.4 L CO₂

Thus, the stoichiometric ratio is: 22.4 L CO₂/100 g CaCO₃

Finally, we multiply this ratio by the mass of CaCO₃ to calculate how many liters of CO₂ at STP are produced:

2380 g CaCO₃ x 22.4 L CO₂/100 g CaCO₃ = 533.12 L

The 533.12 L of carbon dioxide will be produced at STP if 2380 g of calcium carbonate reacts completely.

The balanced chemical equation for the decomposition of CaCO₃ is the following:

CaCO₃(s) → CaO(s) + CO₂(g)

A balanced chemical reaction is an equation that has equal numbers of each type of atom on both sides of the arrow.

According to the equation, 1 mol of CaCO₃ produces 1 mol of gas (CO₂).

We need to convert the moles of CaCO₃ to mass in grams with the molar mass of the compound:

Molar mass CaCO₃ = 100 g/mol

Mass of CaCO₃ = 1 mol x 100 g/mol = 100 g CaCO₃

Now, we know that 1 mol of any gas at STP occupies a volume of 22.4 L:

1 mol CO₂ = 22.4 L CO₂

Thus, the stoichiometric ratio is:  

[tex]\frac{22.4 L\; CO_{2} }{100 g \;CaCO_3 }[/tex]

Finally, we multiply this ratio by the mass of CaCO₃ to calculate how many liters of CO₂ at STP are produced:

2380 g CaCO₃ x 22.4 L CO₂/100 g CaCO₃

= 533.12 L

Hence, the 533.12 L of carbon dioxide will be produced at STP if 2380 g of calcium carbonate reacts completely.

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

Explanation:

So velocity = d/t or distance over time in this case m/s or meters per second. But BE CAREFUL you must remember to convert cm to m always so 135 cm= 1.35m and 1.35m/5.5s= 0.245m/s

Answer:

[OH-] = 2 x 10^-6 M

Explanation:

Calculate pOH first: 14 - pH = pOH --> pH = 14 - 8.3 = 5.7

[OH-] = 10^-pOH = 10^-5.7 = 2 x 10^-6 M

Only one sig fig in the concentration, because the pH only had one decimal place.

Answer: 35.6 g/mol

Explanation: I guessed and got it correct

The molar volume of any gas behaving ideally at STP is 22.414 L. The molar mass of the gas at STP is 35.59 g.

The molar mass of a substance is defined as the mass of one mole of molecules. In other words one gram molecular mass of a substance is same to its molar mass in g mol⁻¹.

The molar mass of a substance can be obtained by adding the atomic masses of each elements.  At 0°C and 1 atm, 1 mole of any gas behaving ideally occupies a volume of 22.414 L.

Here 5.00 L of the gas at STP has a mass of 7.94. Then the molar mass of 22.414 liters of the gas can be calculated as:

7.94 × 22.414/5.00 = 35.59 g.

Thus the molar mass of the gas is 35.59 g.
