Answer:
665 g
Explanation:
Let's consider the following thermochemical equation.
2 C₄H₁₀(g) + 13 O₂(g) → 8 CO₂(g) + 10 H₂O(l), ΔH°rxn= –5,314 kJ/mol
According to this equation, 5,314 kJ are released per 8 moles of CO₂. The moles produced when 1.00 × 10⁴ kJ are released are:
-1.00 × 10⁴ kJ × (8 mol CO₂/-5,314 kJ) = 15.1 mol CO₂
The molar mass of CO₂ is 44.01 g/mol. The mass corresponding to 15.1 moles is:
15.1 mol × 44.01 g/mol = 665 g
Answer:
b. No
Explanation:
The question above is related to "The Law of Conservation of Mass." This law states that <u>mass is neither created nor can it be destroyed.</u> Even if a particular matter will be mixed with another substance or it undergoes chemical reaction,<u> the mass of the matter will remain the same.</u> Even with a change in phase, the mass of the matter will remain the same.
I think its Na3(PO4)+Cu(SO4) --> Na2(SO4) + Cu3(2PO4). Hope am right
Answer:
See explanation
Explanation:
The third element in the first transition series is Vanadium
The fourth element in the first transition series is chromium
Given that we have four d orbitals in universe L instead of five as we have on earth;
The electronic configuration of Vanadium in universe L is;
Ar 3d3 4s2
The electronic configuration of chromium in universe L is;
[Ar] 3d4 4s2
Molarity :
M = n / V
M = 7.00 x 10⁻³ / 12.0
= 0.000583 M => H+
Kw = [ H+] x [OH-]
1 x 10⁻¹⁴ = 0.000583 x [ OH-]
[ OH-] = 1 x 10⁻¹⁴ / 0.000583
[OH-] = 1.71 x 10⁻¹¹
hope this helps!
