Answer:
Its reliability is confirmed by many scientists
Explanation:
The science and the pseudoscience have multiple differences that separate them clearly and sharply. The science, doesn't matter about scientific field we are talking about, is confirmed by numerous scientists. In order for something to be accepted in the scientific circles as a science, the particular thing in question undergoes numerous studies, from numerous different scientists or scientific groups. If all of the results of all of the studies are confirming the same thing, that it can be accepted as science.
Answer:
atmosphere
Explanation:
All living organism cannot live without atmosphere. Atmosphere is the layer that surrounds the earth surface. It has a lot of gasses e.g oxygen, nitrogen, carbon dioxide etcetera
Answer:
49.2°C is the temperature
Explanation:
Based on Charles's law, the absolute temperature of a gas is directly proportional to the volume under constant pressure. The equation is:
V1 / T1 = V2 / T2
<em>Where V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.</em>
<em />
Computing the values of the problem:
V1 = 0.432L
T1 = -20.0°C + 273.15K = 253.15K
V2 = 0.550L
T2 = ?
0.432L / 253.15K = 0.550L / T2
322.3K = T2
322.3K - 273.15 =
<h3>49.2°C is the temperature</h3>
Answer:
A. 3 moles of C will be produced from 1 mole of A
B. 4 moles of D will be produced from 4 moles of A
Explanation:
The balanced equation of the reaction between the three species A, C and D has been given in the question as -
A → 3C + D
According to the coefficients of the above reaction, we can draw the following conclusions -
- 1 mole of A can produce 3 moles of C
- 1 mole of A can produce 1 mole of D
Thus, as asked in the question,
If we are taking 1 mole of A then moles of C that will be produced = 3 moles
Again,
If we take 4 moles of A, then moles of D that will be produced = 4 moles.
Answer:
The oxidation state of the reducing agent has changed from 0 to +2.
Explanation:
reducing agent is anything that loses electron or gains oxygen
in this case, zinc
