Answer:
Al2O3 + 6HCl --> 2AlCl3 + 3H2O
Explanation:
Al: 2
O: 3
H: 6
Cl: 6
Balanced on both sides.
Answer:
Explanation:
The formula for the amount heat q absorbed by a substance is
q = mcΔT
where
m = the mass of the substance
C = the specific heat capacity of the material
ΔT = the temperature change
Data:
q = 2267 J
m = 44.5 g
T₁ = 33.9 °C
T₂ = 288.3 °C
Calculations:
ΔT = (288.3 - 33.9) °C = 254.4 °C
NaNO3 + Pb(C2H3O2)<span>2 would be the answer if you were adding the two. </span>
Answer:
Ký hiệu hóa học (xem thêm ký hiệu) cho nước. Mỗi phân tử nước chứa hai nguyên tử hydro (H) liên kết với một nguyên tử oxy (O).
The chemical symbol (see also symbol) for water. Each molecule of water contains two atoms of hydrogen (H) joined to a single atom of oxygen (O).
This reaction is known as respiration and in order to understand the stoichometry better, we first write the reaction equation:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
From the equation, we can see that the molar ratio between glucose and oxygen is 1 : 6. Therefore, we can see that if 6 moles of oxygen are consumed, one mole of glucose will be consumed.
