The subscript 2 in H2O indicates that there are 2 hydrogen atoms in each water molecule. This is important for balancing chemical equations and understanding the composition of compounds.

How many grams of potassium chlorate decomposes to yield 30 grams of oxygen?

The molar mass of potassium chlorate (KClO3) is 122.55 g/mol. This means that 122.55 grams of potassium chlorate yield 3 moles of oxygen gas. To calculate the amount of potassium chlorate that decomposes to yield 30 grams of oxygen, you can set up a simple ratio using the molar masses.

What do the formulas arrow and plus signs in a chemical equation tell you?

Elements and compounds involved in the reaction, the arrow means "yields" and points to products, and the plus signs indicate two or more reactants or products. ... both reactants and products are written as formulas. Reactants are placed on the left of the reaction arrow, and the other is on the righ

Can you count the number of atoms in a chemical equation?

Yes, you can count the number of atoms in a chemical equation by taking into account the subscripts of each element within the formula. The subscripts represent the number of atoms of each element present in the molecule. By adding up the total number of each atom on both sides of the equation, you can determine the total number of atoms in the chemical equation.

What is the balance form of the chemical equation shown below?

To determine the balanced form of a chemical equation, you need to ensure that the number of atoms of each element is the same on both sides of the equation. If you provide the chemical equation, I can help you determine the balanced form.

What is a challenge of tailoring and balancing intelligence capacity?

One challenge is ensuring that intelligence capacity is tailored to the specific needs and goals of the organization or individual, as this requires a deep understanding of their unique requirements. Another challenge is balancing the level of intelligence gathered to avoid information overload, which can diminish the value and usability of the intelligence. Additionally, maintaining the security and confidentiality of sensitive intelligence information is crucial in order to protect against potential leaks or misuse.

How many grams of ethanol would be formed from the reaction of 0.250 kg of glucose?

The conversion equation of glucose to ethanol is:

C{6}H{12}O{6} → 2C{2}H{5}OH + 2CO{2}

(Where numbers in braces {} should be in subscript which I can't do here)

Thus 1 mole of Glucose forms 2 moles of Ethanol.

1 mole of glucose weighs : 6×12 + 12×1 + 6×16 g = 180g

1 mole of ethanol weighs: 2×12 + 5×1 + 16 + 1 = 46 g

→ 180g of glucose makes 2×46 g = 92 g of ethanol

→ 0.250 kg glucose = 0.250 × 1000 g = 250 g

→ 0.250 kg glucose can produce 250 g ÷ 180 g × 92 g = 127 7/9 g ≈ 128 g of ethanol.

What are the coefficients that will balance this chemical equation PbO2 PbO plus O2?

The balanced chemical equation for the given reaction is: PbO2 + PbO -> 2PbO + O2

Coefficients: 1 PbO2, 1 PbO, 2 PbO, 1 O2.

Why do we need to balance chemical equations and reactions?

Balancing chemical equations is necessary to ensure that the amount of each element present on both sides of the equation is the same. This helps maintain the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Balancing equations also provides information on the stoichiometry of the reaction, including the mole ratios of reactants and products.

What are the reactants and products of chemical equation of photosynthesis?

The reactants of the chemical equation for photosynthesis are carbon dioxide and water. The products are glucose (sugar) and oxygen.

What is the balanced chemical equation for iron (III) nitrate and sodium chloride?

The balanced chemical equation for the reaction between iron (III) nitrate and sodium chloride is: 2Fe(NO₃)₃ + 6NaCl → 2FeCl₃ + 6NaNO₃.

Why sodium hydroxide and hydrochloric acid were added in extraction and write the equations?

Sodium hydroxide was added to extract acidic compounds by converting them into their respective sodium salts, which are water-soluble and can be easily separated. Hydrochloric acid was added to neutralize any excess sodium hydroxide and to protonate basic compounds making them water-soluble as well.

Equations:

  1. NaOH + HCl -> NaCl + H2O
  2. RCOOH + NaOH -> RCOONa + H2O (where RCOOH is the acidic compound being extracted)
  3. R-NH2 + HCl -> R-NH3Cl (where R-NH2 is the basic compound being extracted)

What is the reaction of iodine and oleic acid?

When iodine reacts with oleic acid, it forms iodine addition products. These products result from the addition of iodine across the C=C double bonds present in oleic acid. The reaction typically involves the formation of di-iodo derivatives of oleic acid.

What is the balance chemical equation for the neutralization reaction between sulphuric acid and potash?

The balanced chemical equation for the neutralization reaction between sulfuric acid (H2SO4) and potassium hydroxide (KOH) to produce potassium sulfate and water is:

H2SO4 + 2KOH → K2SO4 + 2H2O

How do I balance this chemical reaction CO2 H2O- C6H12O6 6O2 6H2O?

CO2 H2O- C6H12O6 6O2 6H2O is NOT a chemical reaction. Where are the reactants and the products? Is it CO2 + H2O ==> C6H12O6 + O2 ? That would be an unbalanced equation whose balanced equation would be6CO2 + 6H2O ==> C6H12O6 + 9O2 (NOTE: no H2O on the right side)


What statements are true about balancing equations?

Balancing equations is the process of ensuring that there are an equal number of each type of atom on both sides of a chemical equation. This is achieved by adjusting the coefficients in front of the chemical formulas to balance the equation. The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction, which is why balancing equations is necessary to maintain this principle.

What is the balanced chemical equation for the reaction acetic acid with aluminium hydroxide to form water and aluminium acetate?

The balanced chemical equation for the reaction between acetic acid (CH3COOH) and aluminum hydroxide (Al(OH)3) to form water and aluminum acetate (Al(CH3COO)3) is:

2CH3COOH + 3Al(OH)3 -> 3H2O + Al(CH3COO)3

Why are the state symbols used in chemical equations?

State symbols are used in chemical equations to indicate the physical state of a substance involved in the reaction, such as solid (s), liquid (l), gas (g), or aqueous solution (aq). This information helps to accurately represent the reaction conditions and ensure that the equation is balanced correctly.

What is the chemical equation for the second ionization reaction of phosphoric acid with water?

The second ionization reaction of phosphoric acid (H3PO4) with water is: H2PO4- (aq) + H2O (l) ⇌ H3O+ (aq) + HPO4^2- (aq)

How can you use the law of conservation of mass to help you balance a chemical equation?

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. By balancing a chemical equation so that the number of each type of atom is equal on both sides, you ensure that the total mass of the reactants equals the total mass of the products, reflecting the law of conservation of mass.

What chemical equation of sulphur and hydrogen?

The chemical equation for the reaction between sulfur and hydrogen is: S + H2 → H2S. This reaction forms hydrogen sulfide gas.

What happens when you mix AgNO3 and NH3?

When you mix AgNO3 (silver nitrate) and NH3 (ammonia), a white precipitate of AgCl (silver chloride) forms. This reaction is used to test for the presence of chloride ions in a solution, as silver chloride is insoluble in water and will precipitate out.
