Chemistry
1 answer:
GrogVix [38]4 years ago
7 0

Answer:

The second option

Explanation:

Speed is defined at the rate at which distance changes with time. It is scalar quantity and it is expressed as shown below:

              Speed = \frac{distance}{time}

At constant speed the rate of change of distance with time is the same. On the second graph, this is noticeable. Both distance and time change at the same rate.

Adding an inhibitor to a chemical reaction will have which of the following effects on a reaction?
Levart [38]

Answer: a. the inhibitor will decrease the rate of reaction.

Explanation: The rate of the reaction is affected by addition of inhibitors which are also called as negative catalysts as they decrease the rate of reaction unlike catalysts which enhance the rate of reaction.

Inhibitors delay, slow or prevent the chemical reactions by binding with the substrate or the catalyst and hence prevent them to function normally.

A+common+iv+solution+is+0.9%+saline+(nacl+solution).+what+is+the+osmolarity+of+0.9%+saline+mosmoles/l?+the+molecular+weight+of+n
Vedmedyk [2.9K]

An osmolarity of saline solution is 308 mosmol/L.

m(NaCl) = 9 g; the mass of sodium chloride

V(solution) = 1 L; the volume of the saline solution

n(NaCl) = 9 g ÷ 58.44 g/mol

n(NaCl) = 0.155 mol; the amount of sodium chloride

number of ions = 2

Osmotic concentration (osmolarity) is a measure of how many osmoles of particles of solute it contains per liter.

The osmolarity = n(NaCl) ÷ V(solution)  × 2

The osmolarity = 0.154 mol ÷ 1 L × 2

The osmolarity = 0.154 mol/L × 1000 mmol/m × 2

The osmolarity of the saline solution = 308 mosm/L.
