Why are some elements such as hydrogen, often found as diatomic molecules?
Answer:
Hydrogen chloride, carbon monoxide, or nitric oxide do all have diatomic molecules. In essence, what that means is that they are all gasses at room temperature. Because their atomic nuclei have its origin in different elements, scientists refer to them as heteronuclear.

For the complete encyclopedic entry with media resources, visit: http://www.nationalgeographic.org/encyclopedia/weathering/
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.
Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.
For example, certain kinds of air pollution increase the rate of weathering. Burning coal, natural gas, and petroleum releases chemicals such as nitrogen oxide and sulfur dioxide into the atmosphere. When these chemicals combine with sunlight and moisture, they change into acids. They then fall back to Earth as acid rain.
How is a battery like the mitochondria?
Answer:
mitochondria the tiny powerhouses that live inside cells and give them energy, work more like a Tesla battery pack than the kind of battery that you put in a flashlight. These internal cell structures, or organelles, use oxygen to make chemical units of energy for the cell.1
Explanation:

Do you think a charger would be a good example for mitochondria?
Answer:
not really because mitochondria break down and convert material into energy. a charger just resembles pulling energy from a bigger source.

extra currents in the ground will disrupt power grid operations
signals from radio navigation systems will be disrupted and be inaccurate
signals from radio navigation systems will be disrupted and be inaccurate
satellites will be forced to Earth's surface
satellites will be forced to Earth's surface
high-frequency radio waves used for radio communications will be blocked
Answer: extra currents in the ground will disrupt power grid operations and high-frequency radio waves used for radio communications will be blocked
Explanation:
In the case of a severe geomagnetic storm, extra currents on the ground will disrupt power grid operations and signals from radio navigation systems will be disrupted and be inaccurate.
A geomagnetic storm is caused by a CME (coronal mass ejection) from the sun that smacks against the earth's magnetic field and causes issues such as
Power grid failuresRadio signal disruptionsDamage to critical electronicsEtc.
Extra currents in the ground caused by the geomagnetic storm will disrupt power grid operations. We can also expect a disruption of all radio signals and communications due to changes in the ionosphere during the storm.
Satellites in the Earth's orbit would likely sustain critical damage and may be rendered inoperable, however, since satellites do not use technology to stay in orbit (this is done by the earth's own gravity) they will not fall to the surface, which is why this option is wrong. The final option is also wrong because high-frequency radio waves used for radio communications will be disrupted and unreliable but not blocked.
That is why In the case of a severe geomagnetic storm, power grid operations and signals from radio navigation systems will be disrupted and be inaccurate.

Which of the following cells is formed by meiosis?
A) A heart cell
B) A bacterial cell
C) A sperm cell
D) A fertilized egg
Answer:
C ) A sperm cell
Explanation:
These cells are our sex cells – sperm in males, eggs in females. During meiosis one cell divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes of the parent cell – they are haploid. Meiosis produces our sex cells
One hydrogen bond is _, but many hydrogen bonds are_
Answer:
[tex]\huge\mathfrak\pink{ur}\huge\fbox\green{answer}[/tex]
The hydrogen bond is one of the strongest intermolecular attractions,
A single hydrogen atom can participate in two hydrogen bonds, rather than one. This type of bonding is called "bifurcated" (split in two or "two-forked"). It can exist, for instance, in complex natural or synthetic organic moleculesAnswer:

We usually get some questions about how many hydrogen bonds these compounds can create, we use it to differentiate between the boiling point of each one of them so it would be great if you could help me.
So what I know that H2O has 4 hydrogen bonds those are 2 from hydrogen atoms and 2 from other molecules that has 2 hydrogen atoms connected to the 2 lone pair of electron that the oxygen has.
In HF, It has 2 hydrogen bonds. The same explanation implies here. In NH3, 2 hydrogen bonds because N doesn't have the required amount of lone pairs to make more hydrogen bonds.

Why do you want to read research by scientists who used the scientific method?
Answer:
When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.
Lloyd’s lab partner is looking down into a test tube while he heats the contents by using a flame. Which action should Lloyd recommend to his partner if heating must continue?
Wear safety goggles while looking into the opening of the test tube.
Cover the opening of the test tube so that no materials can boil out of it.
Move the test tube so that the opening is pointing away from all students.
Put the test tube in a hot water bath so that no water can enter its opening.
The correct action that Lloyd should recommend to his partner who was looking down into the test tube if heating must continue would be to move the test tube so that the opening is pointing away from all students.
Wearing safety goggles (and looking directly down at the test tube) might not be enough to protect Lloyd's partner nor other students in case the content of the test tube splashes out.Covering the test tube might hinder any generated gas as a result of heating from escaping safely into the air and this might cause an explosion.Putting the test tube in a hot water bath so that water can enter its opening will definitely affect the reaction and prevent them from getting accurate results/observations.Hence, the most correct action would be for Lloyd's partner to move the test tube so that the opening is pointing away from all students.

Polymers are made of monomers, and both are kinda of compounds? True or false
Answer:
true
Explanation:
i am not sure but i hope it will help you
True, polymers are made of monomers, and both are kinds of compounds
Explanation:
A polymer is a long chain composed of several monomer units which are chemically combined together. Or polymer is a material or substance made up of repeating units called a monomer.The monomer is a simple repeating unit in a polymer. When the several small monomer units combine with each other via a chemical reaction and give out a large chain-like molecule this process is called polymerization.So from this, we can conclude that polymers are made of monomers, and both are kinds of compounds
