Fe & O makes an ionic bond because of this
Metal and Metal = Metallic
Non-Metal and Metal = Ionic
Non-Metal and Non-Metal = Covalent
In this case Oxygen (O) is a Non-Metal and Iron (Fe) is a Metal so you have an Ionic Bond
(I think you have a mistake in your question as the addition is 30mL, not 100mL)
when PH = - ㏒[H+]
and here we have HClO4 is the strong acid
So PH = - ㏒[HClO4]
moles of HClO4 = 0.1 L *0.18 m = 0.018 M
moles of LiOH = 0.03 L * 0.27 m = 0.0081 M
when the total volume = 0.1L + 0.03L = 0.13 L
∴ [HClO4] = (0.018-0.0081)/0.13 L
= 0.076 M
PH = -㏒ 0.076
= 1.12
Answer: shelter
Explanation:
Producers make food for the rest of the ecosystem through the process of photosynthesis, where the energy of the sun is used to convert carbon dioxide and water into glucose.
Answer:
Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).
Explanation:
Answer:
pH = 4.44
Explanation:
You take the negative logarithm of the hydronium ion concentration.
pH = -log[H₃O⁺] = -log(3.6 × 10⁻⁵) = 4.44
