Answer:
the energy value of the olive oil kJ/g = 36.880 KJ/g
Explanation:
we can calculate energy gained by the water which generated by the reaction from this formula :
Q = mc∆t
where:
m is the mass of water= 370 g
c specific heat of water = 4.184 J/g·°C
∆t is the change or difference in temperature in °C = 38.9 - 22.7 = 16.2 °C
by substitution:
Q = 370g * 4.184 J/g.°C* 16.2°C
= 25078.896 Joule
the energy value of the olive oil = Q / mass of olive oil
= 25078.896 Joule/ 0.68 g
=36880 J/g
= 36880 / 1000 = 36.880 KJ/g
I hope this makes a little sense? Review your acid and base chapters. Ive attached the autonionization of water and my work.
Answer:
266 liters Carbon iv oxide will be formed
Explanation:
The first thing we need to do here is to calculate the number of moles of oxygen reacted.
This can be calculated using the ideal gas equation;
Mathematically;
PV = nRT
From the question;
P = pressure = 10.5 atm
V = volume = 400 liters
n = number of moles = ?
T = temperature = 125 + 273 = 398K
R = molar gas constant = 0.0821 L•atm•K^-1•mol^-1
Substituting these values, we have ;
n = PV/RT
n = (10.25 * 400)/(398 * 0.0821) = 125 moles
From the question;
15 moles oxygen gave 10 moles CO2
125 moles oxygen will give x moles CO2
x = (125 * 10)/15 = 83 moles
Now, we want to know the volume of CO2, present in 83 moles using the given reaction conditions.
Mathematically;
PV = nRT
V = nRT/P
= (83 * 0.0821 * 398)/10.25 = 265.65 which is approximately 266 Liters
Answer and Explanation:
Elements : 
these are not compounds because for making compound there should be at least combination of two different elements but are made up of same type of elements so these are elements
Compounds: 
these all are compound because they are made up of different types of elements after combining together
<h3>The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet. If water didn't naturally recycle itself, we would run out of clean water, which is essential to life</h3>
