Nitrate salts (no3), when heated, can produce nitrites (no2) plus oxygen (o2). a sample of potassium nitrate is heated, and the 02 gas produced is collected in a 700 ml flask. the pressure of the gas in the flask is 2.7 atm, and the temperature is recorded to be 329 k. the value of r= 0.0821 atm l/(mol k) how many moles of o2 gas were produced? moles after a few hours, the 700 ml flask cools to a temperature of 293k. what is the new pressure due to the o2 gas?

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
