What characteristic is important for plants found in saltwater wetlands?

Answers

Answer 1
Answer:

Answer : Salinity tolerance

Explanation :

The important characteristics for the plants which are found in salt water wet lands is salinity tolerance.

Salinity tolerance is the salt tolerance of crops in the wet lands which gives maximum salt level that a crop can tolerate without losing its productivity.

Although it may get affected negatively at higher levels of exposure. The salt level is often measured as the soil salinity or else the salinity of the irrigated water.

What determines the order of placement of the elements on the modern Periodic Table?(1) atomic number(2) atomic mass(3) the number of neutrons, only(4) the number of neutrons and protons

Answers

The order of placement of the elements on the modern Periodic Table is determined by their atomic number (option A)

What is atomic number?

The atomic number of an element is the number of protons in the nucleus of an atom of that element. It is a unique identifier for each element, and it is the primary factor that determines the chemical properties of an element.

The Periodic Table is arranged in horizontal rows, called periods, and vertical columns, called groups. The order of placement of the elements on the modern Periodic Table is determined by their atomic number.

The order of placement of the elements on the modern Periodic Table is the atomic number. The answer is number 1. The rest of the choices do not answer the question above. Atomic mass gives the number of mass of an atom. 

Why can molten solution of ionic compounds be electrolysed

Answers

Answer:

the current is carried through the electrolyte by the movement of ions - not electrons.

Explanation:

The reason that an electrolyte has to be molten or in solution is that the current is carried through the electrolyte by the movement of ions - not electrons. In a solid, those ions can't move. It also follows, of course, that an electrolyte must contain ions.

Which term is defined as a measure of the average kinetic energy of the particles in a sample?(1) temperature (3) thermal energy
(2) pressure (4) chemical energy

Answers

Answer: The correct answer is Option (1).

Explanation:

Average kinetic energy is defined as the average of the kinetic energies that is associated to the particles of the sample which are in random motion.

Temperature is the measure of the average kinetic energy of the particles. Formula used for calculating the average kinetic energy is given by:

K=(3)/(2)(R)/(N_A)* T

where,

K = kinetic energy

R = Gas constant

N_A = Avogadro's constant

T = temperature

Kinetic energy is directly proportional to the temperature of the particle.

\text{Kinetic energy}\propto \text{Temperature}

As the temperature increases, the kinetic energy of the particles also increases and vice-versa.

Hence, the correct answer is option 1.

The answer is (1). Temperature is directly proportional to the average kinetic energy of the particles in any given sample of matter, and it is usually defined along those lines.

A mixture of uneven distribution and easy separation is called. homogeneous a solution heterogeneous a standard

Answers

The solutes dissolves in solvent results in the formation of a solution.

Those mixtures in which the components of mixture are uniformly distributed throughout the mixture are said to be homogeneous.  

Those mixtures in which the components of mixture are not uniformly distributed throughout the mixture are said to be heterogeneous.  

Those solutions whose concentrations are accurately known are known as standard.

Hence, a mixture of uneven distribution and easy separation is heterogeneous.




Answer:

A heterogenous separation!

Explanation:

The rate law for a reaction is rate = k[A]2. What is the overall order of this reaction, and which two varaibles, when graphed, will give a straight line for this reaction? A. first order, In[A]t versus t B. first order, 1/[A]t versus t C. second order, In[A]t versus t D. second order, 1/[A]t versus t

Answers

Answer:

D. second order, 1/[A]t versus t

Explanation:

Since the power of the concentration is 2 in the rate law, it is a second order reaction. Also, for a second order reaction, the variables that would yield a straight line when graphed are 1/[A]t versus t
