The answer would be the second answer: the property that gives it mass. This is because energy is t<span>he property of an object or system that enables it to do work. </span>
If you can provide the reaction you are looking at, then we can provide a more satisfactory answer.
If the forward reaction is exothermic, then reducing the temperature where the reaction occurs will shift the equilibrium towards the right. This is because exothermic reactions release heat, and this will counteract the change as stated in Le Chatelier's Principle.
If the forward reaction is endothermic, then reducing the temperature will shift to the left. This occurs as the backward reaction is the exothermic reaction, and by Le Chatelier's Principle, the reaction will favor the reaction that produces more in to counter a reduction in temperature, in this case the backward direction reaction.
Answer:
43.7
Explanation:
mole is equal mass concentration/ moler mass of MgCl²
Answer:
The Machine exerts a force of 9N.
Explanation:
Initial velocity (u) = 0 m/s
Final velocity (v) = 30 m/s
Time (t) = 0.5 s
Acceleration (a) = (v-u)/t
= (30-0)/0.5 m/s²
= 30/0.5 m/s²
= 60 m/s²
Mass = 0.15 kg
Force = Mass*Acceleration
= 0.15*60 N
= 9 N
Hello!
To find the amount of energy need to raise the temperature of 125 grams of water from 25.0° C to 35.0° C, we will need to use the formula: q = mcΔt.
In this formula, q is the heat absorbed, m is the mass, c is the specific heat, and Δt is the change in temperature, which is found by final temperature minus the initial temperature.
Firstly, we can find the change in temperature. We are given the initial temperature, which is 25.0° C and the final temperature, which is 35.0° C. It is found by subtract the final temperature from the initial temperature.
35.0° C - 25.0° C = 10.0° C
We are also given the specific heat and the grams of water. With that, we can substitute the given values into the equation and multiply.
q = 125 g × 4.184 J/g °C × 10.0° C
q = 523 J/°C × 10.0° C
q = 5230 J
Therefore, it will take 5230 joules (J) to raise the temperature of the water.
