1 mol of gas at STP occupy 22,4dm³ (22,4L)
8,482g ------- 2,5L
Xg ------------- 22,4 L
X = 75,999 ≈ 76 g/mol

<h3>
Answer:</h3>
H₂O
<h3>
Explanation:</h3>
The additional product that balances the reaction is water (H₂O).
- Therefore, the complete balanced equation for the reaction is;
H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + H₂O(l)
- Balancing a chemical equation ensures that the law of conservation of mass is obeyed by the reaction.
- The reaction is an example of a neutralization reaction where an acid, H₂SO₄, reacts with a base, NaOH to form a salt and water.
- In this case the salt formed is sodium sulfate (Na₂SO₄)
Human activities that increase the amount of CO2 in the atmosphere include, the burning of coal/ other fossil fuels, cement production, deforestation, and other landscape changes.
Climate change causes the oceans to absorb more heat, resulting in an increase in sea surface temperatures and rising sea levels. This change in ocean temperatures and currents brought about by climate change can lead to alterations in climate around the world.
Climate changes affects crop growth, meat production, fisheries, and other fundamental aspects of our food supply. This is because if our climate is constantly changing our Earth will no longer be able to sustain the adequate necessities of food production.
Climate change cause health issues. Change in climate can cause existing health problems to intensify and new health issues to emerge. Climate change can influence air pollution, allergies, disease carried by vectors, food and waterborne diseases, food security, mental health and stress-related disorders, floods, temperature extremes, and wildfires. All of these factors can have negative effects on ones health.
To reduce the negative effects of climate change we can speak up about climate change, use renewable energy, weatherize, invest in energy-efficient appliances, reduce water waste, make less food waste, etc.
The vapour pressure of a substance actually differs
relative to the temperature. So to know which compound has the vapour pressure
of 58 kilopascals at 65 degrees Celsius, we refer to standard tables of
temperature vs Vapour pressure.
From the tables or graph, the answer here is:
