Answer:
Jean Beguin
Explanation:
The first chemical equation was diagrammed by Jean Beguin in 1615.
It means that the fit and well adjusted ones thrive and "make it", and the weak ones that can't adapt die.
Answer:
<u>4</u>H₂O(l) →<u> 4</u>H₂(g) + <u>2</u>O₂(g)
Balancing equations
1. 3Fe(s) + 4H₂O(g) → Fe₃0₄(s) + 4H₂(g)
2. 2AlBr₃(aq) + 3Cl₂(g) → 2AlCl₃(aq) + 3Br₂(l)
3. 2HNO₃(aq) + Ba(OH)₂(aq) → Ba(NO₃)₂(aq) + 2H₂O(l)
4. 2Al(s) + 3Pb(NO₃)₂ → 2Al(NO₃)₃(aq) + 3Pb(s)
5. 3NaOH(aq) + Fe(NO₃)₃ → Fe(OH)₃(s) + 3NaNO₃(aq)
Explanation:
From the question given, I have been able to balance the chemical equations correctly.
In balancing chemical equations, the chemical equation must have equal number of atoms for each element that are both in the reactant side and in the product side.
For the above to be achieved, the number of atoms in each element will have to be multiplied and added.
A look at the balanced chemical equation above, you will discover that each element has the same number of atoms both in the reactant side and in the product side.
Decomposer, decomposers include fungous, bacteria, worms. They break down trash and bad things and concert it to soil.
The expected final temperature of the block, given that 586 J of heat were added to it is 55.5 °C
<h3>How to determine the final temeprature</h3>
We'll begin by obtaining the change in the temperature of the block. This can be obtained as follow:
- Specific heat capacity of block (C) = 0.240 J/gºC
- Heat added (Q) = 586 J
- Mass of block (M) = 80.0 g
- Change in temperature (ΔT) =?
Q = MCΔT
Divide both sides by MC
ΔT = Q / MC
ΔT = 586 / (80.0 × 0.240)
ΔT = 586 / 19.2
ΔT = 30.5 °C
Finally, we shall determine the final temperature of the block. This can be obtained as follow:
- Initial temperature (T₁) = 25 °C
- Change in temperature (ΔT) = 30.5 °C
- Final temperature (T₂) = ?
ΔT = T₂ – T₁
30.5 = T₂ – 25
Collect like terms
T₂ = 30.5 + 25
T₂ = 55.5 °C
Thus, from the calculation made above, we can conclude that the final temperature is 55.5 °C
