Answer:
The information become scientific when it was proved by different experiments and first it become theory then law and we study these information in books
Explanation:

Answer:</h3>
5.97 g of water
<h3>
Explanation:</h3>
- Quantity of heat is given by multiplying the mass of a substance by specific heat capacity then by change in temperature.
Q = m × c × ΔT
In this case;
Quantity of heat, Q = 125 Joules
Change in temperature = 15°C - 10°C
= 5°C
We know that the specific heat capacity of water is 4.186 J/g°C
Therefore, to get the mass we first rearrange the formula;
Mass = Q ÷ cΔT
= 125 J ÷ (5°C × 4.186 J/g°C)
= 5.97 g
Therefore, the mass of water is 5.97 g
Lithium, sodium, potassium, rubidium, cesium, and francium
Answer:
3.310308*10^26
Explanation:
nO=9nFe2(SO3)3=9*60.1=540.9 moles
number of atoms: 540.9*6.02*10^23
The answer is going to be (a) - oxygen. this is because, for this reaction, charcoal undergoes a combustion reaction, using the oxygen from the surrounding atmosphere to burn to heat, light and CO2.
hope this helps!!
