<u>Answer:</u> The given number is equal to -9.0606\times 10^{5}

<u>Explanation:</u>

Scientific notation is defined as the notation in which a number is expressed in the decimal form. This means that the number is always written in the power of 10 form. The numerical digit lies between 0.1.... to 9.9.....

If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.

We are given:

A quantity having a value of -906,060

Converting this into scientific notation, we get:

\Rightarrow -906,060=-9.0606\times 10^{5}

As, the decimal point is shifting to left side, thus the power of 10 is positive.

Hence, the given number is equal to -9.0606\times 10^{5}

calculate the volume od a CO2 cartridge that has a pressure of 850 PSI at a temperature of 21ºc the cartridge contains 0.273 mol
gladu [14]
Answer is: volume of CO₂ is 0,113 dm³.
Ideal gas law = pV = nRT.
p = 850 PSI = 5860543,6992 Pa.
Psi <span>is the abbreviation of pound per square inch.
T = 21</span>°C = 294,15 K.
n = 0,273 mol.
R = 8,314 J/K·mol.
V = nRT ÷ p
V = 0,273 mol · 8,314 J/K·mol · 294,15 K ÷ 5860543,6992 Pa.
V = 0,00011 m³ = 0,113 dm³.

The gaseous product of a reaction is collected in a 25.0-l container at 27
nataly862011 [7]
To find the number of moles of gas we can use the ideal gas law equation, we dont need to use the mass of gas given as we only have to find the number of moles 
PV = nRT 
P - pressure - 300.0 kPa 
V - volume - 25.0 x 10⁻³ m³
n - number of moles 
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature in Kelvin - 27 °C + 273 = 300 K
substituting these values in the equation 
300.0 kPa x 25.0 x 10⁻³ m³ = n x 8.314 Jmol⁻¹K⁻¹ x 300 K 
n = 3.01 mol 
number of mols of gas - 3.01 mol

When food spoils, it is a chemical reaction. For example, rancid butter is produced when the fat molecules in the butter undergo
Sergio039 [100]

Answer: Decreases the rate of reaction

  • Remove water from food by dehydration.
  • Transport food in a refrigerated truck.
  • Store food in airtight containers.
  • Store food in a refrigerator after opening.

Does not decrease the rate of reaction

  • Store food in the open air.
  • Place food on a warm surface.

Explanation: Dehydration of food excludes water from food which is one of the factor needed by microorganisms for growth, <em>so it decreaese the rate of reaction.</em>

Transporting food in refrigerated trucks lowers the temperature of food and not many microorganisms are active at very low temperatures, so it <em>decreases the rate of reaction.</em>

Storing food in airtight containers excludes air which is one of the factors required for microbial activity, so <em>it decreases reaction rate.</em>

Storing food in refrigerators after opening also <em>lowers the temperature of food and hence the the rate of microbial activit</em>y.

Storing food in the open air <em>does not decrease microbial activity</em> instead it provides microorganisms with the favorable conditions for their activity such as air and water from water vapor in the air.

Placing food on a warm surface <em>does not decrease rate of reaction</em> because microorganisms are very active in warm and humid environments.

Write a net ionic equation to show how piperidine, c5h11n, behaves as a base in water.
lidiya [134]
C_5H_{11}N + H2O ---\ \textgreater \  C_5H_{11}NH^{+} + OH^{-}

Nitrogen lone pair will act as a base,removing H+ from water leaving behind OH- ion. 
Why ?
Because N is a better donor than O.
