Why is it impossible to have a linear trinomial with one variable?

1 answer:

3 0

The linear in "linear trinomial" states that the degree of any monomial (single variable) must be equal to 1. A trinomial implies that there are three variables. An example of a trinomial would be 2x - y + 3z, where there are three variables each to the first degree. Therefore, a linear trinomial could not have only one variable since three variables are required.

When AgNO₃ solution is added to mixture of NaNO₃ and NaCl, it reacts with NaCl and gives precipitate of AgCl, which is white solid. The reaction takes place in 1:1 stoicheometric ratio as per the following balanced reaction:

NaCl + AgNO₃→ AgCl ↓ + NaNO₃. As per reaction 1 mole NaCl reacts with 1 mole AgNO₃ and gives of solid precipitate of 1 mole AgCl.

0.641 g= $\frac{0.641}{143.32}$ = 4.47 X $10^{-3}$ mole of solid AgCl is produced. This indicates 4.47 X $10^{-3}$ mole NaCl = $4.47 X 10^{-3}X58.5$ g of Nacl reacts to give 0.641 g of AgCl. So, mass percentage of NaCl present in mixture= $\frac{0.26}{1.5} X 100$ = 17.33 %.

1. A 250g chunk of metal is heated with 400 joules of energy and the temperature goes from 20 °C to 25°C. What is its specific h

Paha777 [63]

The specific heat capacity of this chunk of metal is equal to 0.32 J/g°C.

<u>Given the following data:</u>

Mass of metal = 250g

Quantity of energy = 400 Joules

Initial temperature = 20°C

Final temperature = 20°C

To determine the specific heat capacity of this chunk of metal:

<h3>The formula for quantity of heat.</h3>

Mathematically, quantity of heat is given by the formula;

$Q = mc\theta$

<u>Where:</u>

Q represents the quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity.

∅ represents the change in temperature.

Making c the subject of formula, we have:

$c = \frac{Q}{m\theta}$

Substituting the given parameters into the formula, we have;

$c = \frac{400}{250 \times (25-20)}\\\\c = \frac{400}{250 \times 5}\\\\c = \frac{400}{1250 }$

Specific heat, c = 0.32 J/g°C.

1. What is the relationship between ecological succession and equlibrium in an ecosystem?

alexandr1967 [171]

Answer:

Equilibrium in ecology refers to a state that occurs such that a small disturbance or change is counter balanced by another change so that the community is restored to its original state. Thus, as a community goes through multiple changes through each stage of succession, it is not in equilibrium.
