Answer:

Sr(NO₃)₂(aq) + Na₂CO₃(aq) ⇒ SrCO₃(s) + 2 NaNO₃(aq)

Sr²⁺(aq) + 2 NO₃⁻(aq) + 2 Na⁺(aq) + CO₃²⁻(aq) ⇒ SrCO₃(s) + 2 Na⁺(aq) + 2 NO₃⁻(aq)

Sr²⁺(aq) + CO₃²⁻(aq) ⇒ SrCO₃(s)

Explanation:

Let's consider the molecular equation that occurs when aqueous solutions of strontium nitrate and sodium carbonate react. This is a double displacement reaction.

Sr(NO₃)₂(aq) + Na₂CO₃(aq) ⇒ SrCO₃(s) + 2 NaNO₃(aq)

The total ionic equation includes all the ions and the insoluble species.

Sr²⁺(aq) + 2 NO₃⁻(aq) + 2 Na⁺(aq) + CO₃²⁻(aq) ⇒ SrCO₃(s) + 2 Na⁺(aq) + 2 NO₃⁻(aq)

The net ionic equation includes only the ions that participate in the reaction and the molecular species.

Sr²⁺(aq) + CO₃²⁻(aq) ⇒ SrCO₃(s)

How many chlorine atoms are on the products side of the reaction 2al 6hcl → 2alcl3 3h2? 2 3 6 9

GenaCL600 [577]

The number of chlorine atoms present on the product side of the reaction is 6

<h3>What is a chemical equation? </h3>

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

<h3>How to determine the number of atoms of Cl</h3>

2Al + 6HCl → 2AlCl₃ + 3H₂

Products => AlCl₃ and H₂

Number of Cl atoms = 2 × 3

Number of Cl atoms = 6 atoms

if an unknown sample solution is prepared by diluting 10.00 ml of the original solution to a total volume of 100.0 ml with deion

Usimov [2.4K]

The dilution factor of the unknown sample is 10. The dilution factor of a solution refers to the ratio of the final volume of the now diluted solution to the initial volume of the of the initial concentrated solution.

Mathematically;

The dilution factor is given by the formula;

Dilution factor = Final volume of the now diluted solution/ Initial volume of more concentrated solution

Final volume of the now diluted solution = 100.0 ml

Initial volume of more concentrated solution = 10.00 ml

Dilution factor = 100.0 ml/10.00 ml

Dilution factor = 10

Corn plants may be tall (TT or Tt) or short (tt). The breeding of two parent corn plants results in offspring that are all tall.

zubka84 [21]

Answer:

Explanation:

The probability that both of the parents are homozygous recessive is zero.
In our case, The gene for tallness is dominant over the gene for dwarfism
Therefore; TT is homozygous dominant while tt is homozygous recessive and Tt is heterozygous.
Heterozygous genotype (Tt) will exhibit a tall phenotype.
When two parents are crossed and all the offsprings are tall then the possible genotype of the parents is either;

Homozygous dominant for both parents or

TT x TT

2. One parent is homozygous dominant and the other is homozygous recessive.

TT x Tt

Therefore, the probability of having both parents as homozygous recessive when all the offspring are tall is Zero.
