What is capillary action? Describe how capillary action shown by water is useful for plants and animals on Earth.

2 answers:

7 0

Answer: The capillary action of water can be defined as the property of water by which it travels through the tube in upward direction which is opposite the gravity.

Explanation: This property of water is due to adhesion, cohesion and surface tension of water which allows it to climb through the tube. This property allows the plants to uptake water from the soil.

The water also moves against the gravity in the body of plants and animals with the help of capillary action.

Explanation:

Capillary action is adhesion of water. In plants, capillary action allows water to move from the roots to leaves. In animals, capillary action plays a role in respiration where oxygen-poor blood oxygenates in the capillaries.

Which describes the products created from fission reactions? Question 3 options:

Ipatiy [6.2K]

Answer: The correct answer is option A.

Explanation:

Nuclear fission reactions are a type of nuclear reactions in which larger nuclei breaks apart into two or more smaller fragment releasing alpha, gamma of beta particles.

There are 3 types of particles that can be released during this process:

1. Alpha particles: These particles are released when a nuclei undergoes alpha-decay process.

$_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}\textrm{Y}+_2^4\alpha$

2. Beta particles: These particles are released when a nuclei undergoes beta-minus decay process.

$_Z^A\textrm{X}\rightarrow _{Z+1}^{A}\textrm{Y}+_{-1}^0\beta$

3. Gamma radiations: these radiations are released when an unstable nuclei gives off excess energy by a process of spontaneous electromagnetic process.

$_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma$

Hence, any of these particles can be released during the process of fission reaction with smaller atoms.

Therefore, the correct answer is option A.

A(g) + 2B(g) → C(g) + D(g)

WITCHER [35]

Answer:

0.169

Explanation:

Let's consider the following reaction.

A(g) + 2B(g) ⇄ C(g) + D(g)

We can find the pressures at equilibrium using an ICE chart.

A(g) + 2 B(g) ⇄ C(g) + D(g)

I 1.00 1.00 0 0

C -x -2x +x +x

E 1.00-x 1.00-2x x x

The pressure at equilibrium of C is 0.211 atm, so x = 0.211.

The pressures at equilibrium are:

pA = 1.00-x = 1.00-0.211 = 0.789 atm

pB = 1.00-2x = 1.00-2(0.211) = 0.578 atm

pC = x = 0.211 atm

pD = x = 0.211 atm

The pressure equilibrium constant (Kp) is:

Kp = pC × pD / pA × pB²

Kp = 0.211 × 0.211 / 0.789 × 0.578²

Kp = 0.169
