The six steps of the scientific are:
1. State the question
2. Conduct research
3. Create a hypothesis
4. Perform the experiment
5. Analyze the data
6. Conclusion
So D. would be the correct answer, even though communicating the results could possibly be a step if it's required.
Answer:
true
Explanation:
heat will destroy the salt components quicker
Answer:
D.A high temperature will make it spontaneous.
Explanation:
we know that
Δ G = Δ H - TΔS
For spontaneous reaction
Δ G should be negative . If Δ G = 0
Δ H = TΔS
T = Δ H / Δ S
At temperature above this T , Δ G becomes negative if Δ S and ΔH are positive .
So at a high temperature will make it spontaneous.
Answer:
Explanation:
An atom is the smallest indivisible particle that takes part in any chemical reaction. They are easily identified distinctively as elements in a compound.
The subscripts accompanying a chemical symbol shows the number of atoms of elements combining to give a compound:
Compound Elements Number of atoms
KBr K Br 2
C₁₂H₂₂O₁₁ 12(C) 22(H) 11(O) 12 + 22 + 11 = 45
KAlSi₃O₈ 1(K) 1(Al) 3(Si) 8(O) 1 + 1 + 3 + 8 = 13
Ag₃PO₄ 3(Ag) 1(P) 4(O) 3+ 1 + 4 = 8
CH₃CO₂C₆H₄COOH 9(C) 8(H) 4(C) 9+8+4 = 21
Answer:
Balanced Eqn
2C2H6 + 7O2 = 4CO2 + 6H2O
From the balanced equation
2((2*12)+(1*6)) of Ethane gave 6((1*2)+16)) of water
60g of Ethane. >. 108g. Of water
Xg > 1.61
X= 1.61*60/108
X= 0.89g
