chemical equation balancer
The new concentration of the KCl solution after mixing 1 L new volume is 0.28 M.
<h3>How do we calculate the concentration?</h3>
Concentration in terms of molarity will be calculated by using the below equation as:
M₁V₁ = M₂V₂, where
M₁ = molarity of old KCl solution = 1.6 M
V₁ = volume of old KCl solution = 175 mL = 0.175 L
M₂ = molarity of new KCl solution = ?
V₂ = volume of new KCl solution = 1 L
On putting all these values on the above equation, we get
M₂ = (1.6)(0.175) / (1) = 0.28 M
Hence resultant concentration is 0.28 M.

Answer:
building really complicated legos
Explanation:
Explanation:
It is given that 44.45 g of hydrocarbon gas produces 2649 kJ or 
of heat.
Also here, 1 lb = 453.592 g.
Therefore, amount of energy released by 453.592 g of hydrocarbon gas will be calculated as follows.
= 
It is known that 1 J = 
.
Hence, = 
= 7.508 Kwh
Thus, we can conclude that the combustion of exactly one pound of this hydrocarbon gas produce 7.508 Kwh energy.
Water is a bent molecule, so it is polar.
