Answer: 4.4
Explanation:
Thats what my computer says after i submit answer
From the information we have, this block of brown sugar has a volume of 8cm3
The mass of the block is 12. 9 grams.
We need to find out the density of the sugar.
For a solid material the formula for calculating density is given as:
Density = mass / volume
Therefore we simply fit in the above given values into this formula, so:
Density = 12.9 / 8
Density = 1.61
Therefore the density of the block of sugar is 1.61g/ml
Since it was specifically stated that heat is released, therefore
heat is located on the right side of the reaction equation. Also stating the
states of each compound, the complete balanced reaction would be:
C2H5OH (l) + 3 02 (g) -----> 2 CO2 (g) + 3 H2O (g) + 1235
kJ
Answer:
C
Explanation:
The reason why C is true is because this species of plant requires certain things to survive, and without said requirements they will die. Hence, the animal that is unable to compete will die and be eliminated from the ecosystem. Hope that helps!
Uhh how was your day or how is it going
