If you dissolve 0.1 mol of formic acid in 1 L of water, ther esulting solution contains 0.004 mol of H₃O+. Based on this informa

zhuklara [117]

In an ideal case, the acid would completely protonate. such an acid would be a strong acid. Dissociation of Formic acid looks like:

HCOOH + H₂O → COOH⁻ + H₃O⁺

one mole of formic acid should give one mole of Hydronium(H₃O⁺) ions

similarly, 0.1 moles of formic acid should produce 0.1 moles of hydronium ions. but we know that it is not the case, a much lesser amount is actually formed.

Which means that Formic acid did not completely dissociate into COOH⁻ and H⁺ ions.

Hence, Formic Acid is a weak acid

what are some negative impacts on the environment and society when the water cycle is disrupted and drought occurs ?

Alborosie

Some of the negative impact of disruption in water cycle are adverse environment, with affected farming, hydroelectricity, and deforestation.

The water cycle has been operated in the environment for the conversion of water in the different states. The water cycle has been operated with the conversion of water from the water body to the clouds by evaporation.

The evaporated water has resulted in clouds, that have been condensed and precipitated in the form of rain. The water cycle helps in maintaining the water balance in the ecosystem. It made the water available for use as well.

The drought has been the condition of the scarcity of water. In this condition, there has been a disruption of the water cycle. Some of the negative impacts resulting from the disruption of the water cycle are:

Adverse environmental conditions
Farming affected by water scarcity
Unavailability of hydroelectricity
Deforestation

An object with mass m is attached to the end of a string and is raised vertically at a constant acceleration of g 6. If it has b

sattari [20]

11/10 MgL work has been done by the tension in the string. If the object has been raised a distance l from rest.

<h3>Define work done?</h3>

The definition of work is expanded so that it encompasses both the forces applied to the body and the overall displacement of the body. A constant force F is present before this block. The objective of this force is to move the body d meters in a straight line in the force's direction.

Given,

Mass of object, M

Acceleration of object, a = g/10

Distance covered vertically, L

Tension of string, T

Work done by tension in string, W

W = T × L

By applying equilibrium force on string,

T - Mg = Ma

g = gravitational acceleration

T - Mg = M (g/10)

T = M(g/10) + Mg

T = 11/10 Mg

By substituting the value in, W = T × L

W = 11/10 Mg × L

W = 11/10 MgL

∴ Work done by tension is 11/10 MgL.

PLEASE HELP<br><br> (1.1232 x 10^5)(6.022 x 10^17).

omeli [17]

(1.1232 * 10⁵) (6.022 * 10¹⁷)

Now, multiply simple numbers together and exponentials, together:
= 1.1232 * 6.022 * 10⁵ * 10¹⁷
= 6.763 * 10²²

In short, Your Answer would be 6.763 * 10²²

Hope this helps!
