Answer:
4.12 mol
Explanation:
Given data:
Moles of LiOH required = ?
Volume of solution = 4.2 L
Molarity of solution = 0.98 M
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
we will calculate the moles from above given formula.
0.98 M = number of moles / 4.2 L
0.98 M × 4.2 L = number of moles
Number of moles = 0.98 M × 4.2 L
Number of moles = 4.12 mol (M = mol/L)
<span>Condensation takes place when gas molecules lose heat and kinetic energy. The warmer molecules are the faster they move. Gas molecules move very quickly and have a lot of kinetic energy and heat energy. As the gas molecules lose heat they also lose kinetic energy. As the molecules slow down they move closer together to form liquids.</span>
I would say the balanced equation for photosythesis is 6CO2 + 6H2O + The amount of energy given from the sunlight. :)
Explanation:
To balance a chemical equation, there are so many approaches to solve the problem.
A balanced chemical equation is one that obeys the law of conservation of matter.
According to this law "matter is neither created nor destroyed by atoms are just rearranged in chemical reaction".
This implies implies that equal number of atoms must be on both sides of the equation.
There are two main approaches to balancing chemical equation;
- Inspection
- mathematical equation
We can inspect the equation and affix the proper coefficients to combining species.
Mathematically, we establish simple solvable algebraic equations to find the number of respective coefficients that will balance the equation:
For example:
H₂ + O₂ → H₂O
mathematically;
aH₂ + bO₂ → cH₂O
conserving:
H : 2a = 2c
O: 2b = c
let a = 1
c = 1
b = 
multiply by 2 to give;
a = 2, b = 1 , c= 2
2H₂ + O₂ → 2H₂O

Answer:
<h2>D</h2>
Explanation:

<em>According to Universe Today, The answer is D because Radiation from the Sun, which is more popularly known as sunlight, is a mixture of electromagnetic waves ranging from infrared (IR) to ultraviolet rays (UV). It of course includes visible light, which is in between IR and UV in the electromagnetic spectrum.</em>
