Why do atoms form bonds with other atoms? Provide example using octet rule

Answers

Answer 1

Answer:

For Covalent bonds, atoms tend to share their electrons with each other to satisfy the Octet Rule. It requires 8 electrons because that is the amount of electrons needed to fill a s- and p- orbital (electron configuration); also known as a noble gas configuration

What kind of rocks would you expect to see on Mars? What evidence supports your response?

Answers

Mars' surface is largely covered with basalt, a volcanic rock covering much of Earth's surface as well. Earth has large amounts of granite in its crust, which Mars appears to lack.

Based on the composition of the martian meteorites and the presence of plains and mountains that look like features produced by basaltic volcanism on Earth, geologists expected to find primarily basalts on Mars.

Is there a relationship between CO2 levels rising and heavy precipitation? If so, what is it?

Answers

Answer:

Explanation:

Yes, there is a relationship between rising CO2 levels and heavy precipitation. As the concentration of CO2 in the atmosphere increases, it leads to a warming of the Earth's surface due to the greenhouse effect. This warming, in turn, causes an increase in the rate of evaporation of water from the Earth's surface, including from the oceans, lakes, and rivers.

This increased evaporation results in more water vapor in the atmosphere, which can lead to heavier precipitation events, including more frequent and intense rainstorms, snowstorms, and other forms of precipitation. This is because warmer air can hold more moisture, making it more likely to produce heavy rainfall.

In addition, the warming of the Earth's surface can also lead to changes in atmospheric circulation patterns, which can further increase the likelihood of heavy precipitation events in some regions.

Overall, the relationship between rising CO2 levels and heavy precipitation is complex and can vary depending on the specific location and other environmental factors. However, there is evidence to suggest that as global temperatures continue to rise due to rising CO2 levels, heavy precipitation events are likely to become more frequent and intense in many parts of the world.

Answer: Yes there is a direct relationship between CO2 and heavy precipitation. Rising in CO2 means increasing the temperature in the atmosphere which causes more water vapor evaporates into the atmosphere and which causes high rainfall or precipitation.

Explanation: Increased atmospheric CO2 levels are causing plant stomata to close, allowing plants to hold more water in their stems, reducing transpiration, and possibly impacting tropical rainfall patterns in varying ways depending on region.

So lets go to newtons laws of motion, basically he said, more force, more movement. But it depends on how heavy the object is.

Sooo The more heavy the box of sand is, The more force he would have to use to move it. You can also relate this to how much he wnted to move it :)

Answers

Answer:

Alkali Metals matches with solids at room temperature

Noble Gases matches with don't react naturally with other elements

Halogens matches with very reactive nonmetals

Alkali Metals match with solids at room temperature.

Noble Gases matches don't react naturally with other elements.

Halogens match with very reactive nonmetals.

Are alkali metals solid at room temperature?

1. Alkali metals are solid at room temperature (except hydrogen) but have a relatively low melting point: lithium melts at 181 ° C, sodium at 98 ° C, potassium at 63 ° C and rubidium at 39 °. At C, cesium melts at 28 ° C ° C.

2. There is almost no helium (He) on top of the noble gas, and its shell is filled with only two electrons. The fact that their outer shell is full means that they are very happy and do not have to react with other factors. In fact, they are rarely combined with other elements. This non-reactivity is the reason they are called inactive.

3. Halogen elements have seven valence electrons, so only one additional electron is needed to form a complete octet. This property makes it more reactive than other non-metal groups.

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)

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
