Hello..!
There are 2 main types of ions one is an atom where the electrons are shared between the atoms. the other is an electron where one atom loses an electron to become a neutral in a charged ion, and the other atom gains the electron to become a charged lon anion.

Ions with a positive charge are known as cations. Those that are negatively charged are called anions.

The two main types of bonds formed between atoms are ionic bonds and covalent bonds. An ionic bond is formed when one atom accepts or donates one or more of its valence electrons to another atom. A covalent bond is formed when atoms share valence electrons.

A. For every six moles of carbon dioxide consumed, one mole of water is consumed
B. For every mole of carbon dioxide consumed, one mole of water is consumed
C. For every gram of carbon dioxide consumed, one gram of water is consumed
D. For every six grams of carbon dioxide consumed, one gram of water is consumed.
Answers
Answer:

Explanation:
Because of the physics of it.
According to the overall equation of photosynthesis as follows: 6CO2 + 6H2O = C6H12O6 + 6O2, for every mole of carbon dioxide consumed, one mole of water is consumed.
What is photosynthesis?Photosynthesis is the process by which plants and other photoautotrophs convert light energy into chemical energy.
Photosynthesis makes use of carbon dioxide and water to produce glucose and oxygen as follows:
6CO2 + 6H2O = C6H12O6 + 6O2
This chemical equation suggests that for every mole of carbon dioxide consumed, one mole of water is consumed.

is (H2O) water a compound of a element? is Ozone a compound of a element? explain. please help me!!
Answers
Answer:
H20 is a compound and ozone is a compound to because the got more then u elements in it
Explanation:
Answer:
Water is a compound because it is composed from two hydrogen atom and one oxygen atom. Water is considered a compound because it is made up of more than one element. By definition, a compound is composed of multiple atoms from different elements. Water has 2 hydrogens and 1 oxygen.
A compound is a combination of more than one element.
A molecule is the smallest particle of an element or a compound.
Oxygen(O) is an element.
O2 - is a molecule which is formed by making a double bond with another Oxygen.
O3 - is a molecule as well, which comprises of three oxygens with two single bonds and one double bond. The resonance structure has a partial positive charge on the central Oxygen and partial negative charges on the end oxygens.
Explanation:
"In summary, the modern definition of a compound is a type of molecule consisting of at least two different types of atoms. By this definition, water is both a molecule and a compound. Oxygen gas (O2) and ozone (O3), for example, are substances that are molecules but not compounds."
When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as

Ionic and covalent bonds help arrange atoms into unique structures for proteins like hemoglobin. Why is this necessary?(1 point)
Answers
Answer:
Ionic bonds can be important to protein structure because they are potent electrostatic attractions. In the hydrophobic interior of proteins, ionic bonds can even approach the strength of covalent bonds
Covalent bonds in amino acids are useful to stabilize the structure of the proteins and their interactions. The ionic bond formed as the atoms in amino acids with opposite charges accompanied strong electrostatic attractions.
What types of bonds are involved in protein structure?Proteins are 3D structures of amino acids that are further made of an amine and a carboxyl group, and are arranged in specific structures in four levels to give rise to the complete protein molecule.
Proteins can be described as the polymers of polypeptides which are structured by arrangements of these chains in a three-dimensional structure. They are folded and are driven by special non-covalent interactions such as peptide bonds, ionic bonds, hydrogen bonds, Van der Waals interaction, and disulfide bridges.
The primary structure is the sequence of amino acids through peptide bonds to form a polypeptide chain. The secondary structure is a sub-structures made by hydrogen bonding between the main chain peptide groups on the polypeptide backbone chain.
Tertiary structure is the 3D arrangement of protein in which α and β helices are folded into a globular structure with the interactions such as hydrogen bonds, salt bridges, disulfide bonds, and tight packing of side chains.

What impact does bleached coral have on the ecosystem in which it lives?
Answers
Answer:
Bleached corals are likely to have reduced growth rates, decreased reproductive capacity, increased susceptibility to diseases and elevated mortality rates. Changes in coral community composition can occur when more susceptible species are killed by bleaching events.
Bleached corals are more likely to have slower growth rates, fewer eggs, a lower ability to resist disease, and higher mortality rates.When more vulnerable species are wiped out by bleaching events, changes in the composition of the coral ecosystem might result.
What is coral reef ?Coral reefs are the most diverse ecosystem in the world providing habitat to aquatic livings. The coral pulps are made of calcium carbonate. Coral bleaching and the related mortality not only harm coral populations, but also fish communities, human communities, and other living things that depend on coral reefs and associated fisheries for their survival.
The species that rely on coral communities, like as fish and invertebrates that need living coral for food, shelter, or spawning grounds, are also impacted by changes to these communities.
When corals die as a result of coral bleaching, there may be changes in the abundance and makeup of reef fish assemblages. When corals perish due to bleaching, genetic and species diversity may be reduced.

For the first four, we encounter common examples in everyday life, all to do with water:
Freezing - liquid to solid, e.g. water to ice, e.g. making ice cubes.
Melting - solid to liquid, e.g. ice to liquid water, melting ice cubes or snow flakes.
Condensation - gas to liquid, e.g. water vapor (gas) to liquid - water vapor in air (humidity) condenses to form liquid droplets on the outside of a cold beverage glass on a hot humid day; or cloud formation in the atmosphere.
Evaporation - liquid to gas, e.g. liquid water on clothes evaporates as clothes dry on clothesline or in dryer
While water can sublime under certain conditions of temperature and pressure, it is less evident in everyday life. Carbon dioxide however is a more common example.
Sublimation - solid to gas, e.g. "dry ice" disappearing. The visible smoke associated with dry ice is most likely just condensing water vapor in the air as the solid carbon dioxide cools the air.

Volume of objects using sinker methodAn object that floats on water will displace its own volume. In the same vein, an object that sinks in water will displace its own volume.
Thus, in order to find the volume of an object that sinks in water, measure the volume of water that it displaces.
In this case, the water displaced by the key was measured 3 times. The average of the 3 readings will give the volume of the key.
Volume of the key = 0.7 + 0.8 + 0.9/3 = 0.8 mL
