How would doubling the concentration of crystal violet affect the reaction rate?

Chemistry
1 answer:
Helga [31]3 years ago
5 0

Actually the rate of reaction can be shown as:

R = k [A]^x [B]^y

The rate of reaction can be determined with help of order of reaction which is an experimental quantity and the order can be determined experimentally.

Hence for the rate of reaction crystall violet depends on order of crystall violet and mostly the order of crystall violet is 1 and thus on doubling the concentration, the rate of reaction gets doubles.

Convert .0150 km to meters and express the correct significant figures
weeeeeb [17]
<h3>Answer:</h3>

15.0 meters

<h3>Explanation:</h3>
  • Kilometers are units used to measure length.
  • Length is also measured using other units which include meters, centimeters, decimeter, millimeter, etc
  • To convert one unit to another we use conversion factors.

In this case to know inter-conversion between units of measuring length, we consider the following;

Kilometer(km)

10

Hectometer(Hm)

10

Decameter(dam)

10

Meter (M)

10

Decimeter (dm)

10

Centimeter (cm)

10

Millimeter (mm)

Therefore, to convert km to meter we use the conversion factor (10×10×10) 1000 m/km.

Thus;

0.0150 km is equivalent to;

= 0.0150 km × 1000 m/Km

= 15.0 meters

Thus, 0.0150 km is equivalent to 15.0 meters.

How many of the organisms represented are multicellular
kari74 [83]
<span> Son organismos que pertenecen al Nivel de Organización Protoplasmático. Son UNICELULARES y se distinguen por no poseer un Núcleo bien organizado. Son PROCARIOTAS porque el material genético (ADN o Cromosomas) al no tener Carioteca o Membrana Nuclear, se encuentran dispersos en el Citoplasma. Comprenden a las Cianofíceas y Bacterias. Las Cianofíceas o Algas verde azuladas son Autótrofos, ya que realizan la Fotosíntesis y algunas Bacterias se nutren por Absorción, ya sea descomponiendo a sustratos orgánicos como las Saprófitas, o infectando a un organismo vivo y viviendo a expensas de él como las Parásitas y otras son Heterótrofas y Autótrofas. Poseen un Sistema de Nutrición AUTÓTROFA, HETERÓTROFA y por ABSORCIÓN. Las Bacterias son Células muy pequeñas, que tienen Reproducción Asexual por Fisión Binaria. Tienen Pared Celular porosa. Presentan diferentes Formas (Cocos, Bacilos, Espirilos, Vibriones). Producen Enfermedades (Tuberculosis, Lepra, Sífilis, Neumonia, etc.) Hay Bacterias Beneficiosas (Producción de alcohol y vinagre, quesos, yogurth, etc.). Las CIANOBACTERIAS poseen CLOROFILA y un Pigmento azul llamado FICOCIANINA. Pueden estar libres o en colonias. </span>

A sample of gas has a pressure of 100.0 KPa and 25C. Calculate the pressure if the temperature is changed to 125C while the volu
atroni [7]

Answer:

133.56kPa

Explanation:

Applying Pressure Law,

P/T = P'/T'....................... Equation 1

Where P = Initial pressure, T = Initial Temperature, P' = Final pressure, T' = Final Temperature.

From the question, we were asked to calculate P'

There, we make P' the subject of the equation

P' = PT'/T...................... Equation 2

Given: P = 100kPa, T = 25°C = (273+25) = 298K, T' = 125°C = (273+1250K = 398 K

Substitute these values into equation 2

P' = (100×398)/298

P' = 133.56kPa

Hence the pressure is 133.56kPa
