Answer:
By allowing the potatoes to be stored longer so they can be sold during winter months.
Explanation:
Since low energy particles are fired at the potatoes to prevent them from developing unwanted sprouts, it means that it prevents sprouts from growing on the potatoes.
Now, winter is wet period which encourages more growth of the sprouts. Thus, the way this development will affect the industry is that the potatoes will be stored for longer period and then sold in the winter.
Answer:
The heat produced by this reaction is 2887J
Explanation:
The reaction of HCl with NaOH occurs as follows:
HCl + NaOH → H2O + NaCl + ΔH
<em>Where ΔH is released heat due the reaction</em>
<em />
The equation of a coffee cup calorimeter is:
Q = C*m*ΔT
<em>Where Q is heat produced, </em>
<em>C is specific heat of the solution (4.18J/g°C), </em>
<em>m is mass of the solution (50mL + 50mL = 100mL = 100g -Because density is 1g/mL) </em>
<em>and ΔT is change in temperature (28.9°C - 22.0°C = 6.9°C)</em>
<em />
Replacing:
Q = 4.184J/g°C*100g*6.9°C
Q = 2887J
The heat produced by this reaction is 2887J

The correct answer is <span>a. CaO(s) + H2O(l) Ca(OH)2 (s)
</span><span>Decreasing in entropy means that you have to get a solid from the liquid
</span>therefore : <span>CaO(s) + H2O(l) Ca(OH)2 (s)
This formula will make it absolutely clear

Answer:
When light passes from one transparent medium to another, the rays are bent toward the surface normal if the speed of light is smaller in the second medium than in the first. The rays are bent away from this normal if the speed of light in the second medium is greater than in the first.
Explanation:
Answer:
Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.
