Answer:
<h2>Solution:</h2><h3>A solution is a homogeneous mixture of two or more substances. They are stable in nature.</h3>
<h2>Suspension:</h2><h3>These are a heterogeneous mixture. They are unstable in nature.</h3>
1 result would be the decimation of crops and vegetation, which causes a reduction in farmers income rates which could lead to his workers losing their jobs or even poverty

Answer:
In the absence of ethylene hormone,growth and development of plant do't takes place.
Explanation:
Ethylene is an important plant hormone that in produced by plants for the purpose of growth, development and respond to stress for various purpose through out it's life cycle.
They are volatile and are also required in the field of agriculture for ripening of fruits, seed germination, root stem development,sex determination etc.
Over use of ethylene may provide harmful impact on the plant as it spoil the products.
We know that the pH of neutral solutions is 7, for acidic solutions is less than seven and for basic solutions is greater than 7.
pH = -log[H+]
pH = -log ( 1 x 10⁻⁴)
pH = 4
The answer is:
A) Acidic
Answer:
3.1atm
Explanation:
Given parameters:
Volume of gas = 2L
Number of moles = 0.25mol
Temperature = 25°C = 25 + 273 = 298K
Unknown:
Pressure of the gas = ?
Solution:
To solve this problem, we use the ideal gas equation.
This is given as;
PV = nRT
P is the pressure
V is the volume
n is the number of moles
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
P =
Now insert the parameters and solve;
P = = 3.1atm
