PH scale is used to determine how acidic or basic a solution is.
we have been given the hydrogen ion concentration. Using this we can calculate pH,
pH = - log[H⁺]
pH = - log (1 x 10⁻¹ M)
pH = 1
using pH can calculate pOH
pH + pOH = 14
pOH = 14 - 1
pOH = 13
using pOH we can calculate the hydroxide ion concentration
pOH = - log [OH⁻]
[OH⁻] = antilog(-pOH)
[OH⁻] = 10⁻¹³ M
hydroxide ion concentration is 10⁻¹³ M
Answer:
I feel as though you are missing information to this question.
Explanation:
elements on the periodic table, today, are arranged based on physical properties, such as valence electrons, atomic mass, etc.
Answer:
1.Precipitation
2.Transpiration
3.Condensation
4.Evaporation
5.Evaporation
3.Condensation
Explanation:
Rain pours from the sky occurs due to the process of precipitation, leaves of the plant dried due to the process of transpiration in which the water is evaporated from the body of plant, fluffy clouds form in the sky occurs in the process of condensation, bathing suit dries after swim is due to evaporation in which water is removed and goes into the atmosphere and water puddles disappear due to the process of evaporation. Evaporation is the removal of water from the any surface whereas transpiration is the removal of water from plant body parts.
Answer:
a) 113g Sr3(PO4)2
b) 1.5g H2
Explanation:
The number of moles of Sr used in the equation
= mass/ molar mass
=65.30/87
= 0.751mol
Since the mole ratio of Sr: Sr3(PO4)2 is 3:1
moles of Sr3(PO4)3 = 1/3*0.751
= 0.25mol
grams of Sr3(PO4)3 is = moles * molar mass
= 0.25 * 452
= 113g
b). Since mole ratio of Sr:H2 is 3:3
moles of H2 = 0.751 * 3/3 ---> 0.751 mol
grams of H2 is = moles * molar mass
= 0.751 * 2
= 1.502g
