Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation y

ou submit is balanced. (You can edit both sides of the equation to balance it, if you need to.) Note: you are writing the molecular, and not the net ionic equation. CaCl2(aq) + H20(I)

Answer:

The reactants are Ca(OH)2(s) and HCl(aq)

The balanced equation is

Ca(OH)2(s) + 2HCl(aq) → CaCl2(aq) + 2H20(I)

Explanation:

Step 1: Data given

The products of the equation are: CaCl2(aq) + H20(I)

Step 2: The unbalanced equation

Ca^2+(aq) + 2Cl-(aq) + H+(aq) + OH-(aq) → CaCl2(aq) + H20(I)

Ca(OH)2(s) + HCl(aq) → CaCl2(aq) + H20(I)

Balancing the equation

Ca(OH)2(s) + HCl(aq) → CaCl2(aq) + H20(I)

On the left side we have 1x H, on the right side we have 2x H (in H2O). To balance the amount of H on both sides, we have to multiply HCl by 2.

When we multiply HCl by 2, the amount of Cl on both sides is also balanced. Now the equation is balanced.

Ca(OH)2(s) + 2HCl(aq) → CaCl2(aq) + 2H20(I)

The reactants are Ca(OH)2(s) and HCl(aq)

The balanced equation is

Ca(OH)2(s) + 2HCl(aq) → CaCl2(aq) + 2H20(I)

Answer:

CaCl₂(aq) + 2H₂O(I)  →  Ca(OH)₂(aq) + 2HCl(g)

Explanation:

The reactants are:

CaCl₂ and water (H₂O)

The products are:

HCl and Ca(OH)₂

The balanced equation is:  CaCl₂(aq) + 2H₂O(I)  →  Ca(OH)₂(aq) + 2HCl(g)

1 mol of calcium chloride reacts with 2 moles of water, in order to produce calcium hydroxide and 2 moles of hydrogen chloride.

Original molarity was 1.7 moles of NaCl

Final molarity was 0.36 moles of NaCl

Given Information:

Original (concentrated) solution: 25 g NaCl in a 250 mL solution, solve for molarity

Final (diluted) solution: More water is added to make the new total volume 1.2 liters, solve for the new molarity

1. Solve for the molarity of the original (concentrated) solution.

Molarity (M) = moles of solute (mol) / liters of solution (L)

Convert the given information to the appropriate units before plugging in and solving for molarity.

Molarity (M) = 0.43 mol NaCl solute / 0.250 L solution = 1.7 M NaCl (original solution)

2. Solve for the molarity of the final (diluted) solution.

Remember that the amount of solute remains constant in a dilution problem; it is just the total volume of the solution that changes due to the addition of solvent.

Molarity (M) = 0.43 mol NaCl solute / 1.2 L solution

Molarity (M) of the final solution = 0.36 M NaCl

I hope this helped:))

Cellular respiration involves the use of oxygencarbon dioxide and the release of carbon dioxideoxygen
Reil [10]
Cellular respiration can be thought of as the opposite of photosynthesis.  In cellular respiration oxygen is turned into carbon dioxide  while in photosynthesis carbon dioxide is tuned to oxygen.

I hope this helps. let me know in the comments if anything is unclear.

If you react 2.00 g of hydrogen completely using 15.87 g of oxygen to produce water, how much water (in grams) will you have?
leonid [27]

Answer:

The amount (mass) of water we will have is 17.869 grams

Explanation:

The molar mass of hydrogen gas H₂ = 2.016 grams/mole

The molar mass of oxygen gas = 31.999 g/mol

Therefore, 2.00 g of hydrogen will give;

2.00/2.016 = 0.9921 moles of H₂ gas and

15.87 g of O₂ will give;

15.87/31.999 = 0.49595 moles

The reaction is as follows;

2H₂ (g) + O₂ (g) → 2H₂O (l)

Two moles of H₂ react with one mole of O₂ to produce two moles of H₂O

Therefore 0.9921 moles of H₂ will react with 0.9921/2 or 0.49595 moles of O₂ to produce 0.9921 moles of H₂O

From the above we note that all the H₂ and O₂ are completely consumed to form 0.9921 moles of H₂O

Molar mass of H₂O = 18.01528 g/mol

Number of moles = Mass/(Molar mass)

∴ Mass of H₂O = (Molar mass) × (Number of moles)

= 18.01528 g/mol × 0.9921 moles = 17.869 grams

Therefore the amount (mass) of water we will have = 17.869 grams.

) determine the henry's law constant for ammonia in water at 25°c if an ammonia pressure of 0.022 atm produces a solution with a
Nataly [62]

Answer:

a. 59 m/atm

Explanation:

  • To solve this problem, we must mention Henry's law.
  • <em>Henry's law states that at a constant temperature, the amount of a given gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.</em>
  • It can be expressed as: C = KP,

C is the concentration of the solution (C = 1.3 M).

P is the partial pressure of the gas above the solution (P = 0.022 atm).

K is the Henry's law constant (K = ??? M/atm),

∵ C = KP.

∴ K = C/P = (1.3 M)/(0.022 atm) = 59.0 M/atm.

when 48 .0g of carbon reacts with oxygen gas to form carbon dioxide, no carbon or oxygen is left over. How much oxygen is reacte
Arte-miy333 [17]

Answer:

128g

Explanation:

Given parameters:

Mass of carbon  = 48g

Mass of carbon dioxide  = 176g

Unknown:

Mass of oxygen that reacted  = ?

Solution:

Every chemical reaction must obey the law of conservation of mass. It states that "in a chemical reaction, matter is neither created nor destroyed" .

So;

     Mass of carbon + Mass of oxygen  = Mass of carbon dioxide

Mass of oxygen  = Mass of carbon dioxide  - Mass of carbon

Mass of oxygen  = 176  - 48  = 128g
