Answer: 15 and 16
Explanation:
You can set up an equation N is one positive integer, and N+1 is the second (because they are consecutive, so it's the first number plus one).
Equation to solve for N
N(N+1) = N + (N+1) + 209
N^2 + N = 2N +1 + 209
N^2 - N - 210 = 0 (factor here)
N = 15 or N = -14
Since the question asks for the positive integers, you know the first number is 15, then the next would be 16.
The addition of sodium bicarbonate to carbon treatments is fundamental because this substance has buffer properties.
<h3>What is a buffer?</h3>
In chemistry, a buffer is any substance that may act both as an acid or base in a given solution.
Sodium bicarbonate is a fundamental buffer in biological systems because it may prevent different types of homeostatic imbalances (e.g., acidosis).
In conclusion, the addition of sodium bicarbonate to carbon treatments is fundamental because this substance has buffer properties.

The final temperature on the block is 25 degrees.
Heat is a form of energy. This question shows that energy is transferred from the acetone to the metal block.
Data given;
- M1 = 3.33g
- T1 = 25 degrees
- M2 = 44g
- T2 = 25 degree
- C1 = 124.5 J mol K
- C2 = 0.89 J/g K
<h3>Heat Transfer</h3>
Applying the principles of heat transfer,
Heat loss = Heat gain
From the calculation above, the final temperature on the block is 25 degrees.

Answer:
Many other power plants like coal-fired power plants have cooling towers or these large bodies of water as well. This similarity exists because the process of turning heat into electricity is almost identical between nuclear power plants and coal-fired power plants.
Explanation:
It is a safety procedure in industries that lock dangerous machines and ensure that there is no operation until maintenance or repairs have been made.
