Chemistry

matrenka [14]3 years ago

Answer:

In chemistry, in general terms, a substrate is a substance that other substances can react with and cause it to change into something else by the reaction.

Explanation:

The word “substrate” can have different meanings, it depends on which science we are talking about.

In chemistry, in general terms, a substrate is a substance that other substances can react with and cause it to change into something else by the reaction.

In biochemistry, the enzyme substrates are organic materials where an enzyme acts to cause a reaction. The enzyme just acts as a catalyst and is not affected by the reaction, as it does not change its chemical structure.

In biology, a substrate is the material where organisms grow and live in optimal conditions and with the necessary nutrients.

In geology, the layers found beneath the soil are called substrates.

John rode 3150 m at an average speed of 350 m/min.If he had ridden at average of 375 m/min instead. How much sooner would it hav
Svet_ta [14]

Explanation:

Given that:

Distance traveled = 3150m

Average speed = 350m/min

Suggested speed = 375m/min

Unknown:

Time = ?

Solution:

Speed is the rate of change of distance with time.

  it is mathematically expressed as;

     speed = \frac{distance }{time}

Initial time using speed 350m/min can be calculated by making time the subject of the formula;

     time taken = \frac{distance }{speed}

    time taken at speed of speed of 350m/min = \frac{3150}{350} = 9min

   to seconds = 9 x 60 = 540 seconds

  time taken at speed of 375m/min = \frac{3150}{375} = 8.4min

   to seconds = 8.4 x 60 = 504 seconds.

It could have taken 504 seconds sooner saving 36 seconds.

Calculate the grams of solute in each of the following solution: 278 mL of 0.038 M Fe2(SO4)3
Goryan [66]

Answer:  4.22 grams of solute is there in 278 ml of 0.038 M Fe_2(SO_4)_3

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n}{V_s}

where,

n = moles of solute

V_s = volume of solution in L

Now put all the given values in the formula of molality, we get

0.038M=\frac{n}{0.278L}

n=0.0105mol  

mass of  Fe_2(SO_4)_3 = moles\times {\text {Molar Mass}}=0.0105\times 399.88g/mol=4.22g

Thus 4.22 grams of solute is there in 278 ml of 0.038 M Fe_2(SO_4)_3
