According to Le Chatelier's Principle, to increase the rate of the forward reaction we add more of the reactants to encourage more collisions and production of more products. If it is endothermic, more heat should be added. If it is endothermic, more heat should be released from the system.
Explanation:
In order to justify Marian's statement we have to look at the '' Amount per serving calories'' ⇒
In food label A we can see that this value is 160 calories
In food label B we can see that this value is 50 calories
⇒ 160 calories is slightly more than three times 50 calories
Otherwise If we want to justify Johan statement we need to look at the '' serving size '' ⇒
In food label A we can see that the serving size is 1 cup (237 mL)
In food label B we can see that the serving size is 
cup (56g)
Working with the information of the food label A we can write the following expression :
⇒ Looking at the value of ''
'' ⇒
If we look at the same amount of portion volume :
In cup of food A we have 40 calories
In cup of food B we have 50 calories
We could conclude that Food B has more calories.
That's how both claims could both be justified.
Biomes are typically characterized based on the dominant plant and animal species found in a certain geographic area. Temperature and precipitation are what determine the geographic distribution of a biome which species can live there.
False
Answer:
Cp = 0.237 J.g⁻¹.°C⁻¹
Explanation:
Amount of energy required by known amount of a substance to raise its temperature by one degree is called specific heat capacity.
The equation used for this problem is as follow,
Q = m Cp ΔT ----- (1)
Where;
Q = Heat = 640 J
m = mass = 125 g
Cp = Specific Heat Capacity = <u>??</u>
ΔT = Change in Temperature = 43.6 °C - 22 °C = 21.6 °C
Solving eq. 1 for Cp,
Cp = Q / m ΔT
Putting values,
Cp = 640 J / (125 g × 21.6 °C)
Cp = 0.237 J.g⁻¹.°C⁻¹
