Magma- hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed by cooling. Hope this helps!
<span>We can use the heat
equation,
Q = mcΔT </span>
Where Q is the amount of energy transferred (J), m is
the mass of the substance (kg), c is the specific heat (J g⁻¹ °C⁻¹) and ΔT is the temperature
difference (°C).
Let's say
heat gained by 100.10 g of water at 10°C = Q₁
heat lost from 100.0 g of water at 60 °C = Q₂
Final temperature of the mixture = T
<span> Since, there is no heat is lost to the surroundings,
Q</span>
₁ = Q₂ mc(T - 10) = mc(60 - T)
Since, m is same for both sides (100.0 g) and c is a constant for the water, we can cut off m and c from both sides. Then,
(T - 10) =(60 - T)
2T = 60 + 10
2T = 70
T = 35 °C
Hence, final temperature of water is T = 35 °C.
Answer:
6 protons and 8 neutrons (please help me with my questions too!)
Explanation:
The atomic mass is 18, if you subtract the atomic number ( the number of protons) to the atomic mass you get it.
Hey there!:
Total volume of wine = 750ml
volume ℅ of ethanol = 12
%
volume of ethanol = (12ml/100ml)*750ml = 90ml
Density of Ethanol = 0.789 g/ml
Mass of Ethanol = 0.789 g/ml × 90ml = 71.01 g
Molar mass of ethanol = 46 g/mol Nº of mole of ethanol = Mass/molar mass
=> 71.01 g /46(g/mol)= 1.5437 moles
Hope this helps!
