How do composers interact with their ecosystem

1 answer:

4 0

Composers or consumers eat the by-product of plants in order to get proper nourishment and development. Their waste excretions are in the soil which nourishes it. This is also used by the plants as producers in order to produce more food for the consumers. When consumers die, they become food for the decomposers such as worms, fungi, bugs, and ants so consumers help them to thrive. In the process, the soil becomes nourished of the mineral breakdowns from the body of the consumers, this is again used by producers to provide healthy and nourished foods.

PH of 0,035M HCl? How to count if your calculator hasn't got -lg?

IrinaK [193]

Given information:

Concentration of HCl = 0.035 M

To determine:

pH of the solution

Explanation:

Hydrochloric acid, HCl is a strong acid. It will completely dissociate to give H+ and Cl- ions

HCl → H+ + Cl-

Hence the concentration of H+ = Cl- = 0.035M

Now, pH measures the strength of H+ ions in a given solution. It is expressed as:

pH = -log[H+]

pH (HCl) = -log(0.035) = 1.46

Ans: pH of 0.035M HCl is 1.46

the chloride of a metal M contains 47.25% of metal 1.0 gram of metal would be displaced from a compound by 0.88 gram of another

GenaCL600 [577]

Answer:

The equivalent weight of M is approximately 31.8 g

The equivalent weight of N is approximately 27.98 g

Explanation:

The given parameters are;

The percentage of the the metal M in in the chloride = 47.25%

Where by the chemical formula for the metal chloride is MClₓ, we have;

47.25% of the mass of MClₓ = Mass of M = W

Therefore, we have;

$\dfrac{0.4725}{W} = \dfrac{1}{W + 35.5 \cdot x}$

0.4725 × (W + 35.5·x) = W

0.4725·W + 0.4725×35.5×x = W

W - 0.4725·W = 16.77·x

0.5275·W = 16.77·x

W/x = 16.77/0.5275 = 31.799 = The equivalent weight of M

The equivalent weight of M = 31.799 ≈ 31.8 g

Given that 1 gram of M is displaced by 0.88 gram of N, then the equivalent weight of N that will displace 31.799 = 0.88 × 31.799 ≈ 27.98 g

The equivalent weight of N = 27.98 g.
