Answer:
B. Are c considered plants or animals?
Explanation:
The question that will be asked to show the problems associated with this type of model is the position of bacteria in the model because bacteria are neither animals nor plants and have a completely different system.
Bacteria are single-celled while plants and animals are multicellular. Bacteria are prokaryotic so they also lack nucleus and do not have any membrane-bound organelles while plant and animals cell have.
Hence, the correct option is "B. Are c considered plants or animals?".
Answer:
Even small amounts of radiation over a prolonged period of time can be dangerous.
Explanation:
We all get exposed to radiation, such as through x-rays, and it's fine as one off experiences. However, if you're constantly dealing with radiation without any sort of protection, no matter how small the amount is, it could potentially lead to consequences like cancer. This is due to the fact that radiation can alter our genes
Answer:
3:2, B
Explanation:
The mole ratio is simply the coefficients in a balanced chemical reaction and their relation to each other.
One simple way to easily know b is the correct answer is to look at the units for the answer choices. A is a ratio of Fe to Fe, C is a ratio of Mg to Fe, and d is a ratio of Mg to Fe. That alone must mean B is the correct answer.
We can also use the definition of a mole ratio, as stated above. Given that this equation is balanced, the mole ratio is simply the ratio of the coefficients, and is thus 3:2.
Hope you find this answer I need points
Answer:
ΔT = 76.5 °C
Explanation:
Given data:
Amount of water = 100.0 g
Energy needed = 32000 J
Change in temperature = ?
Solution,
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Now we will put the values in formula.
Q = m.c. ΔT
ΔT = Q / m.c
ΔT = 32000 j/ 100.0 g × 4.184 j/g. °C
ΔT = 32000 j / 418.4 j /°C
ΔT = 76.5 °C
