To correct her measurement to standard temperature and pressure (STP), she must <span>make a volume correction based on a higher temperature of 273 K. The answer is letter B. This is in order to correct the temperature and pressure because correcting the volume will indicate that the temperature and pressure will result to the opposite result of the volume. This is because volume is indirectly proportional with pressure and temperature.</span>

What pressure is exerted on the bottom of a 0.500-m-wide by 0.900-m-long gas tank that can hold 50.0 kg of gasoline by the weigh
Natasha_Volkova [10]

Answer:

1088.89 Pa

Explanation:

According to the Newton's second law of motion:-

Force=Mass\times Acceleration

Mass = 50.0 kg

Acceleration = g = 9.81 m/s²

So,  

Force=50.0\times 9.8\ kgm/s^2

Force = 490 N

Area of the base = length\times breath = 0.500\times 0.900 m² = 0.45 m²

<u>Pressure = Force/Area = \frac{490\ N}{0.45\ m^2} = 1088.89 Pa</u>

What are some of the benefits of using measurements to find density? Provide 2 each. What are some of the challenges of using me
stellarik [79]

Some of the benefits of using measurements to find density include the following:

  • It is easy and doesn't require experiments.
  • The volume of both light and dense molecule can be gotten.

Some of the challenges of using measurements to find density include the following:

  • Inconsistency in the grind setting
  • Temperature changes not taken into account.

<h3>What is Density?</h3>

This is defined as the mass per unit volume of a substance or te degree of compactness of a substance and can be gotten with the use of measurements or experiments.

The measurement doesn't take the temperature changes into consideration which will lead to the result being most likely incorrect. It is also advantageous because less time is used thereby making it easier.

Reduce the following molecular formulas to empirical formulas. Please help!
zvonat [6]
This is done by reducing each number by a common factor for each formula.

C3H6O6- all can be divided by 3 -> CH3O3 (you don't have to put a 1 for C, only if your teacher requests it. It is generally understood if not written)

H2O2- all can be divided by 2 -> H1O1 (had to put the 1's bc of the unintended language) 

C8H8S2- all can be divided by 2 -> C4H4S 

P5O15- all can be divided by 5- PO3

*****it is important to note that <em>all </em>numbers in the molecular formula are divided by the same thing to reduce them. decimals are <em>never </em>used in empirical formulas, only whole numbers.*****

In the combustion of gasoline, if it is calculated that 250.15 g of CO2 will be produced, but only 212.48 g are collected, what
S_A_V [24]

Answer:

To calculate the Carbon Dioxide - CO 2 - emission from a fuel, the carbon content of the fuel must be multiplied with the ratio of molecular weight of CO 2 (44) to the molecular weight of Carbon (12) -> 44 / 12 = 3.7 Emission of CO 2 from combustion of some common fuels are indicated in the table
