Answer:
            <span>When baking soda is mixed with vinegar, a Neutralization reaction takes place.

Explanation:
                   The reaction of Baking sode (NaHCO</span>₃) and Vinegar (Acetic Acid) takes place in two steps.

Step 1:
           In first step a Double Displacement Reaction takes place between baking soda and acetic acid.

               NaHCO₃  +  CH₃COOH    →    CH₃COONa  +  H₂CO₃

Step 2:
           The Carbonic acid (H₂CO₃) formed in first step undergoes Decomposition Reaction as it is unstable.

                                 H₂CO₃     →      CO₂    +    H₂O

The palmetto landfill in greer, sc supplies over 50% of the energy for the bmw plant there. this reduces carbon dioxide emission
Verdich [7]
Hello there!

The answer is 92000 tons per year

The palmetto landfill supplies methane (CH₄) for the BMW plant there. The gas is used to operate the turbines used to power the BMW campus. It reduces carbon dioxide emissions because the combustion of methane produces fewer CO₂ than the combustion of other gases like propane or butane, which are commonly used for powering turbines.

A scientist could use DNA as a molecular clock to do which of the following? (2 points)
ad-work [718]

Explanation:

<u></u>

<u>-to determine how long ago two species of animals shared an ancestor</u>

<u></u>

The molecular lock describes a method which utilizes mutation rates for DNA over time, to determine the divergence of two species sharing common ancestry,due to evolution. Along with  genetic drift, selective mating and natural selection, evolution may occur within populations due to spontaneous heritable changes to DNA, called mutations, over time.

Further Explanation:

During reproduction, other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

The equation below represents a double replacement/displacement reaction;
Naddik [55]
AB+XY->AY+XB
We know that the answer would be KCl because of the switching that takes place during a double displacement reaction. Just like Zn and MnO4 switched and combined, the remaining elements, K and Cl, will combine.
We know that the answer is simply KCl because both K and Cl have an ion of only +/-1, meaning when they cross, no suffixes are made, since their ions are only 1.
For example, if you combined Mg with Cl, you would get MgCl2, because Mg has an ion of +2.
I hope this helps!
