Answer:

True

Explanation:

This means the fuel is highly flammable hence it has a low ignition temperature. This, therefore, means it burns fast without putting in a lot of energy to ignite it. Even in cars, therefore, the compression ratios, in engines using these of these fuels, is lesser.

In the first 22.0 s of this reaction, the concentration of HBr dropped from 0.590 M to 0.465 M . Calculate the average rate of t

Alex

This is an incomplete question, here is a complete question.

Consider the following reaction:

$2HBr(g)\rightarrow H_2(g)+Br_2(g)$

In the first 22.0 s of this reaction, the concentration of HBr dropped from 0.590 M to 0.465 M . Calculate the average rate of the reaction in this time interval.

Answer : The average rate of reaction is, $6.25\times 10^{-3}M/s$

Explanation :

The given chemical reaction follows:

$2HBr(g)\rightarrow H_2(g)+Br_2(g)$

The average rate of the reaction for disappearance of HBr is given as:

$\text{Average rate of disappearance of HBr}=-\frac{\Delta [HBr]}{\Delta t}$

where,

$C_2$ = final concentration of HBr = 0.465 M

$C_1$ = initial concentration of HBr = 0.590 M

$\Delta t$ = change in time = 22.0 s

Putting values in above equation, we get:

$\text{Average rate of reaction}=-\frac{(0.465-0.590)M}{20.0s}\\\\\text{Average rate of reaction}=6.25\times 10^{-3}M/s$

Hence, the average rate of reaction is, $6.25\times 10^{-3}M/s$

What are the 3 body systems that process the molecules from the food we eat and the air we breathe?

Ludmilka [50]

Answer:

respiratory, digestive and circulatory system

Explanation:

the respiratory system brings oxygen into the lungs when you breathe. the digestive system breaks food down into nutrients such as glucose. the circulatory system transports glucose and other nutrients from the digestive system to the cells.
