Cause of imagination
저 하늘의 오렌지빛 마법이 끝이 나기 전에
'Cause of imagination 그 찰나에
Can you feel the rush? Can you feel the rush?
시간아 멈춰줘
I wanna stay, hey (Can you feel the rush? Can you feel the rush?)
두 세계의 경계선 그 틈에 너와 나를 남기고파 (Come on, let's do it)
I wanna stay, hey (Can you feel the rush? Can you feel the rush?)
개와 늑대의 그 시간엔 마법 속에 갇히고파 (Blue hour!)
1) Chemical equation
<span>2NH4Cl(s)+Ba(OH)2⋅8H2O(s)→2NH3(aq)+BaCl2(aq)+10H2O(l)
2) Stoichiometric ratios
2 mol NH4Cl(s) : 54.8 KJ
3) Convert 24.7 g of NH4Cl into number of moles, using the molar mass
molar mass of NH4Cl = 14 g/mol + 4*1 g/mol + 35.5 g/mol = 53.5 g/mol
number of moles = mass in grams / molar mass
number of moles = 24.7 g / 53.5 g/mol = 0.462 moles
4) Use proportions:
2 moles NH4Cl / 54.8 kJ = 0.462 moles / x
=> x = 0.462 moles * 54.8 kJ / 2 moles = 12.7 kJ
Answer: 12.7 kJ

Answer:
The answer to your question is below
Explanation:
Polyatomic ions are ions composed for more than 1 atom. There are polyanions and polycations.
Polyanions have a negative charge and polycations have a positive charge.
Examples
Polyanions Polycations
acetate CH₃COO⁻ ammonium NH₄⁺¹
bromate BrO₃⁻
chlorate ClO₃⁻
hydroxide OH⁻
nitrate NO₃⁻
nitrite NO₂⁻
sulfate SO₄⁻²
phosphate PO₄⁻³
permanganate MnO₄⁻
We write parentheses before or after a polyatomic ion to emphasize that the oxidation number of the atom which interacts with it affects all the atoms that form part of the polyatomic ion.
Should this not be in biology? But the answer is Endoplasmic reticulum
The answer is D. Stainless steel is made up of the metals, chromium, nickel, among others like aluminum and silicone.
