Nady [450]

Answer:

As for your question, I know to forget to put the options, specifically that your question is incomplete.

Explanation:

Although it could help you by telling you that always a reaction that seeks to balance the pH, and achieve neutrality ... It is necessary to achieve a concentration of OH equal to that of H +, in this way the hydroxyl and the protons.

1. How many molecules are in 643.21 grams of
Veronika [31]

Answer: Calculate the molar mass of Mg3(PO4)2 in grams per mole or search for a chemical formula or substance.

Missing: 643.21 ‎ Must include: 643.21. A balloon is filled with 36.2 liters of Cl2 gas at STP. How many moles of chlorine gas are inside? Solution: 36.2

Missing: 4.061 ‎Must include: 4.061 .For H2O, there is one atom of oxygen and two atoms of hydrogen. A molecule can be made of only one type of atom. In its stable molecular form, oxygen exists as two atoms and is written O2. to distinguish it from an atom of oxygen molecule of three oxygen atoms, in grams per mole or search for a chemical ... Did you mean to find the molecular weight of one of these similar formulas- 80.34.

12oz of water initially at 75oF is mixed with 20oz of water intiially at 140oF. What is the final temperature?
Kaylis [27]

Answer:

115.625^{\circ}\text{F}

Explanation:

m_1 = First mass of water = 12 oz

m_2 = Second mass of water = 20 oz

\Delta T_1 = Temperature difference of the solution with respect to the first mass of water = (T-75)^{\circ}\text{F}

\Delta T_2 = Temperature difference of the solution with respect to the second mass of water = (T-75)^{\circ}\text{F}

c = Specific heat of water

As heat gain and loss in the system is equal we have

m_1c\Delta T_1=m_2c\Delta T_2\\\Rightarrow m_1\Delta T_1=m_2\Delta T_2\\\Rightarrow 12(T-75)=20(140-T)\\\Rightarrow 12T-900=2800-20T\\\Rightarrow 12T+20T=2800+900\\\Rightarrow 32T=3700\\\Rightarrow T=\dfrac{3700}{32}\\\Rightarrow T=115.625^{\circ}\text{F}

The final temperature of the solution is 115.625^{\circ}\text{F}.

In an experiment to find the concentration of calcium hydroxide in limewater , 25.0 cm3 of limewater needed 18.8 cm3 of 0.0400 m
Andre45 [30]

Answer:

0.01504 mol/dm3

Explanation:

Calcium Hydroxide - Ca(OH)2

Hydrochloric acid - HCl

The reaction between both is given as;

2HCl   +   Ca(OH)2   --> CaCl2  + 2H2O

2   :  1

The relationship between the concentration and volume is given as;

CaVa  /  CbVb = na  /  nb

where a = acid (HCl) and b = base Ca(OH)2

Inserting the values;

0.04 * 18.8  /  (Cb * 25)  =  2 / 1

0.752 / 25Cb = 2

Cb = 0.752 / 50  = 0.01504
