Answer:

Direct-air capture

Explanation:

To understand the technology I'm about to explain, I'll model it to something familiar. As you know, the process of  photosynthesis is where trees and plants use sunlight, water, and carbon dioxide to create energy for themselves, and release oxygen as a byproduct. Direct- air capture is exactly like this. Its pulls in air and then through a range of similiar chemical reactions, it extracts the carbon dioxide from it while returning the rest of the air to the surrounding environment. Except, the Direct-air capture does this at a much faster rate than nature does. The direct-air capture uses a ginormous fan that pulls air in which then passes over plastic surfaces that have potassium hydroxide solutions covered over them. The potassium hydroxide solution chemically binds with the carbon dioxide molecules, removing them from the air and trapping them in the liquid solution as a carbonate salt. The carbon dioxide is then contained where it is compressed and purified and then stored for later use.

Answer:

C

Explanation:

The answer is C, because nitrogen is in purple, and oxygen is in blue, and in NO2 you have 2 oxygen atoms.

The Lewis structure along with bonds for ethene (C₂H₄) is drawn below-

A Lewis Structure is a very simplified representation of the valence shell electrons in a molecule. It is used to show how the electrons are arranged around individual atoms in a molecule.

The shared pairs of electrons are drawn as lines between atoms, while lone pairs of electrons are drawn as dots next to atoms.

They also display the total number of lone pairs present in each of the atoms that constitute the molecule.

Explanation:

To balance an equation, the amount of atoms on each side must be equal.

Atom Count on Reactant Side:

Atom Count On Product Side:

As you see, to simply balance the equation, put the 2 in order for the atom count on the reactant side to be equal to the product side. The 2 will add one more of each atom so that its the same as the product side.

Answer:

-85 °C

Explanation:

O and S are in the same group( Group 16). Since S is below O it's atomic mass is higher than O. So molar mass of H2S is higher than H2O. The strength of Vanderwaal Interactions ( London dispersion forces) increases when the molar mass increases. However, only H2O can form H bonds with each other. This is because electronegativity of O is higher than S and therefore H in H2O has a higher partial positive charge than H of H2S.

H bond dominate among these 2 types of forces so the strength of attractions between molecules is higher in H2O than H2S. Therefore more energy should be supplied for H2O to break inter

molecular forces and convert from solid to liquid state than H2S. So mpt of H2O must be higher than that of H2S.

Answer:i think its d not sure tho

Explanation:

Answer:

933.33 m/ min

Explanation:

1 mile = 1.6 km

So the car travels 1.6× 35 km in 1 hour

One hour has 60 minutes

So speed of car = 1.6×35 km / 60 minutes

1km = 1000 m

Speed = 1.6×35×1000 m/ 60 minutes

= 933.33 meters per minute

A car is traveling 35 miles per hour. The speed that is measured in meters per minute is 933.33 m/ min.

Speed is the dimension of distance. It is calculated in meters per second. It is the rate of change of an object in a direction. Speed is calculated by dividing the distance by time. It is a scalar quantity.

Given, that a car is traveling 35 miles per hour. The speed is given, in miles we just have to convert the miles into meters per minute. Miles if the English unit of measurement and meter is the SI unit of measurement.

1 mile = 1.6 km

So the car travels 1.6× 35 km in 1 hour

One hour has 60 minutes

So speed of car = 1.6×35 km / 60 minutes

1km = 1000 m

Speed = 1.6 × 35 × 1000 m/ 60 minutes

= 933.33 meters per minute

Thus, the speed of the car is 933.33 m/ min.

In this case, according to the given information about the oxidation numbers and the compounds given, it turns out possible to figure out the oxidation number of manganese in both MnI2, manganese (II) iodide and MnO2, manganese (IV) oxide, by using the concept of charge balance.

Thus, we can define the oxidation state of iodine and oxygen as -1 and -2, respectively, since the former needs one electron to complete the octet and the latter, two of them.

Next, we can write the following [tex]x[/tex], since manganese has five oxidation states, and it is necessary to calculate the appropriate ones:

[tex]Mn^xI_2^-\\\\Mn ^xO_2^{-2}[/tex]

Next, we multiply each anion's oxidation number by the subscript, to obtain the following:

[tex]Mn^xI_2^-\rightarrow x-2=0;x=+2\\\\Mn ^xO_2^{-2}\rightarrow x-4=0;x=+4[/tex]

Thus, the correct choice is Manganese has an oxidation number of +2 in Mnl2 and +4 in MnO2.

Work is said to be done if the force applied to a body causes the body to move through a distance.

Student B used more work and power

Workdone = Force * Distance

For student A:

Force = 3N

distance = 5meters

Time taken = 10 secs

Workdone by Student A = 3 * 5

Workdone by student A = 15Nm

Power used up = workdone/time

Power used up = 15/10

Power used up = 1.5 Watts

For student B:

Force = 6N

distance = 5meters

Time taken = 5 secs

Workdone by Student A = 6 * 5

Workdone by student A = 30Nm

Power used up = workdone/time

Power used up = 30/5

Power used up = 6 Watts

This shows that student B used more work and power
