What is the primary difference between two different isotopes?
Answer:
Because different isotopes have different numbers of neutrons, they do not all weigh the same or have the same mass. Different isotopes of the same element have the same atomic number. They have the same number of protons. The atomic number is decided by the number of protons.

Why do engineers use metals in making
electrical wires
Answer:
Why is copper used for most electrical wiring? All metals have some amount of resistivity to electrical currents, which is why they require a power source to push the current through. The lower the level of resistivity, the more electrical conductivity a metal has
a. Identify the type of reaction shown:
Li + CaCl2 ---> LiCl + Ca
Answer:
single-replacement reactions
Explanation:
A single-replacement reaction is defined as a chemical reaction in which one strong element replace the other weak element.
The given chemical equation Li + CaCl2 ---> LiCl + Ca is an example of single-replacement reactions in which Lithium (Li) is stronger than Calcium (Ca) and replaces calcium to form bond with Chloride.
Hence, the correct answer is "single-replacement reactions".

what is photosysthies
Answer:
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
Explanation:
Answer:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Explanation:
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Photosynthesis provides us with most of the oxygen we need in order to breathe. We, in turn, exhale the carbon dioxide needed by plants. Plants are also crucial to human life because we rely on them as a source of food for ourselves and for the animals that we eat.

A student did an investigation to determine the effect the amount of air would have on plant growth. She planted identical
plants in 4 separate closed containers with different volumes of air. She measured the height of the plants after they had
grown for 3 weeks.
What is the dependent (responding) variable in her investigation?
Answer:
Explanation:
The responding variable always is measured against the variable that you have control over.
In this case, you have control over the volume of air.
The responding variable is the amount the plant has grown. This would be a good long term experiment to try for a science fair or just because you might be interested. It's a good simple idea.
In your lab group you combined vinegar and water and observed the results shown in the picture. Choose ALL of the evidence that
supports that a chemical change has occurred.
A gas is produced.
B)The color changed.
c) Bubbling occurred.
D) The baking soda dissolved.
E) There is a change in the composition of the reactants.
ANOTHER HELP OVER HEREEEEEE PLSSSSSSS
The declaration made in the image's results indicates that a chemical shift has taken place. There occurs the creation of gas.
What occurred when you put vinegar in the water?This occurs as a result of vinegar's composition of acetic acid and water. Acetic acid and water molecules create robust connections. These bonds cause the molecules inside the solution to move more slowly than those in pure water, hastening the freezing of the solution.
Briefing:A cup of vinegar and a cup of warm water are the basic components of the vinegar cleaning solution. Grease as well as hard water stains are easier to remove with warm water. It may be best to combine the vinegar and distilled water rather than tap water when filling a spray container that will be used often.
To create a chemical reaction, what can you combine with vinegar?A chemical reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate) results in the production of salt (sodium acetate), water, and carbon dioxide gas.

Q+ ( poistive ion ) is an ion of element Q.
What has the highest value in the ion?
The proton number has the highest value in the ion
In an atomic element Q, the mass number is the number of the proton and the neutron, the electron encircles around the nucleus of the atomic element.
Recall that:
The electron is usually negatively charged;The neutron is a neutralThe proton is usually positively charged.∴
The atomic element Q+ has a positively charged ion, Thus, the proton number in the mass of the atomic element Q, therefore, has the highest value in the ion.

Limonene is an oil from oranges and lemons. Click on all the carbon
atoms its structures that have a trigonal planar molecular geometry.
Answer:
See explanation
Explanation:
Limonene is an oil from oranges and lemons. Its structure has been shown in the image attached to this answer.
There are two different groups of carbon atoms in limonene. One group of carbon atoms are sp2 hybridized while the other group are sp3 hybridized. The group of carbon atoms that are sp2 hybridized have a trigonal planar geometry and have been accurately labeled in the image attached while the carbon atoms that are sp3 hybridized were also labelled and have a tetrahedral geometry.
Hence in limonene, there are trigonal planar and tetrahedral carbon atoms.

Write the complimentary DNA strand for the given strand of DNA
CGTAAGCGCTAATTA
Answer:
The answer is GCATTCGCGATTAAT
Explanation:
"Chargaff's rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine."

How did boyle's change the way scientists make discoveries
Robert Boyle established chemistry as a discipline based on measurement, freeing it from the mysticism and alchemy that had plagued it. He introduced the concept of chemical analysis and defined elements, compounds, and mixes.
Boyle used a vacuum chamber to alter the gas's pressure in order to find the link between pressure and volume in a gas, which is now known as Boyle's law. In order to demonstrate that pressure and volume are inversely related to one another, he made detailed observations and carried out a number of experiments.
He developed a new vacuum pump and performed experiments in vacuum, they found that neither sound nor flame could exist there.
