Answer:
what is ionic? Is it iron
Explanation:
Chemical reaction: C + O₂ → CO₂.
Law of conservation of mass <span>states that for any </span>system closed<span> to all transfers of </span>matter<span> and </span>energy<span>, the </span>mass<span> of the system must remain constant over time.
</span><span>In </span>chemical reactions<span>, the mass of the chemical components before the reaction (in this reaction carbon and oxygen) is equal to the mass of the components after the reaction (carbon dioxide).
</span>If we use one mole of substances, that:
mass of reactants is: 12 g (C) + 2·16 g (O) = 44 g.
mass of product is: 12 g + 32 g = 44 g.
<u>Answer:</u> The final temperature of the coffee is 43.9°C
<u>Explanation:</u>
To calculate the final temperature, we use the equation:
where,
q = heat released = 
m = mass of water = 10.0 grams
C = specific heat capacity of water = 4.184 J/g°C
= final temperature = ?
= initial temperature = 20°C
Putting values in above equation, we get:
Hence, the final temperature of the coffee is 43.9°C
It is called a ionic bond or a electrovalent bond. Hope it helps :)
