<h3><u>Answer;</u></h3>
10.80 ° C
<h3><u>Explanation;</u></h3>
From the information given;
Initial temperature of water = 24.85°C
Final temperature of water = 35.65°C
Mass of water = 1000 g
The specific heat of water ,c = 4.184 J/g °C.
The heat capacity of the calorimeter = 695 J/ °C
Change in temperature ΔT = 35.65°C - 24.85°C
= 10.80°C
It is B, and also for a moment I didn't understand that 4.69 x 10^22. I almost did this whole problem wrong.
Answer:
The starting position of this object is 3 m
The object is traveling at a velocity of 3 m/s
Explanation:
Answer:
3 element i.e carbon (C), hydrogen (H) and oxygen.
Explanation:
The following data were obtained from the question:
Subtance >>>>>>>> Chemical Formula
Glucose >>>>>>>>> C₆H₁₂O₆
Methane >>>>>>>> CH₄
Ethanol >>>>>>>>> C₂H₅OH
Hydrogen peroxide >> H₂O₂
From the above table, we can see that ethanol (C₂H₅OH) contains carbon (C), hydrogen (H) and oxygen
Therefore, the total number of elements present in ethanol, C₂H₅OH is 3.
Answer:
6 moles of oxygen, or 3O2.
Explanation:
I would build a proportion for this:
![\frac{2(2)}{2} = \frac{12}{x} \\ 4x = 24 \\ x = 6](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%282%29%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B12%7D%7Bx%7D%20%20%5C%5C%204x%20%3D%2024%20%5C%5C%20x%20%3D%206)
