Answer:

the answer is 5 miles per hour

Step-by-step explanation:

because the difference between 125 and 250 is 125 and you know that's you rate of change. so we know 0 in time would also be 0 in distance. but since it's one you divide 125 by 5 = 25

HI decomposes into its elements according to second-order kinetics. What concentration of HI remains from an initial concentrati

Novosadov [1.4K]

Answer:

Therefore (2.30-0.03747)= 2.2625 M of HI remains from an initial concentration of 2.30 M after 4.5 hours.

Step-by-step explanation:

second order reaction: The rate of reaction proportional to the square of the concentration of reactant.

For second order reaction

$k=\frac{x}{ta(a-x)}$

K is rate constant = 1.6×10⁻³M⁻¹hr⁻¹

a = initial concentration of reactant = 2.30 M

a-x = concentration of reactant after t h

t = time = 4.5 h

Putting the values in the above equation,

$1.6\times 10^{-3}= \frac{x}{4.5 \times 2.30 \times (2.30-x)}$

$\Rightarrow 16.56 \times 10^{-3}\times (2.30-x)= x$

$\Rightarrow 16.56 \times 10^{-3}\times 2.30-16.56 \times 10^{-3}\times x= x$

$\Rightarrow (1+16.56 \times 10^{-3}) x=16.56 \times 10^{-3}\times 2.30$

$\Rightarrow x = 0.03747$

Therefore (2.30-0.03747)= 2.2625 M of HI remains from an initial concentration of 2.30 M after 4.5 hours.

Liam's bottle had 2 1/2 cups of juice in it. He drank 1/3 of the juice in his bottle. How many cups of juice did Liam drink?

myrzilka [38]

You basically have to do 2 1/2 times 1/3....

$2 \frac{1}{2} * \frac{1}{3} = \frac{5}{2} * \frac{1}{3} = \frac{5*1}{2*3} = \frac{5}{6} \ \textless \ -answer$

A chemical manufacturer wishes to obtain 700 litres of a 24% acid solution by mixing a 40% acid solution with a 15% solution. Ho

vekshin1

00 x 0.24 = a x 0.40 + ( 700 -a ) x 0.15 = 0.40 a - 0.15 a + 105.00
168.00 = 0.25a + 105.00 
a = 252 
Solution with 40% ....................252 liters........................ans 

Solution with 15 % ...................700 - 252= 448 liters.........................ans
