how many molecules of oxygen are needed to make 3.5 oxygens of water?
Answer:
57.6g
Explanation:
So, if in one mole of water, 16 g of oxygen atom is present. Then, in 3.6 moles of water, the mass of oxygen present will be 3.6×16=57.6g. Therefore, the amount of oxygen present in 3.6 g water is option (B)- 57.6 g.
What are three ways that the climatic factors of temperature and
sture affect rate of weathering?
Answer:
Generally, interactions with air, water and living organisms cause the weathering of rocks. Although there are two major types of weathering processes, physical weathering and chemical weathering cannot be separated, and they often work together at different rates to break large rocks into smaller pieces over time.

The 5000 kilogram truck
Explanation:
The 5000 kilogram truck is using less force to move vs the 10000 kilogram truck because 5000 kilogram truck is lighter and so needs half the speed as the 10000 kilogram truck.

At this location, it is summer in the Northern Hemisphere because the North Pole is tilted
Away from the sun
Towards the sun
Answer:
This happens twice a year during Earth's orbit. Near June 21 the north pole is tilted 23.5 degrees toward our Sun and the northern hemisphere experiences summer solstice, the longest day of the northern hemisphere year.

There are 300 light particles in an airtight container. Which adjustment would increase the speed of the particles?
A. keeping the volume constant and replacing the light particles with heavy particles
B. keeping the pressure constant and increasing the temperature
C. keeping the volume constant and cooling the container
D. keeping the temperature constant and increasing the container volume
There are 300 light particles in an airtight container. The adjustment that would increase the speed of the particle is keeping the pressure constant and increasing the temperature. Option B is correct.
The speed of a particle is the distance traveled by one molecule of a substance. Particles travel as a result of the kinetic energy they possess.
The kinetic energy attributed to each particle rises as the temperature rises.
As a result, in 300 light particles, the particles will travel more quickly when the temperature is increased while the pressure of the particle remains constant.
Therefore, we can conclude that the adjustment that would increase the speed of the particles is keeping the pressure constant and increasing the temperature.

Characteristics of a compound
The properties of a compound are different from the properties of its constituents. Formation of a compound is generally accompanied by evolution of energy in the form of heat or light. A compound has a fixed melting point and boiling point. A compound is always homogeneous in nature.

Which statement is true about a neutral solution?
Its pH is less than 7.
Its pH is greater than 7.
It has the same concentration of hydronium and hydroxide ions.
It has a greater concentration of hydroxide ions than hydronium ions.
Answer:
C. It has the same concentration of hydronium and hydroxide ions.
Explanation:
A neutral solution means that it's a balanced substance that is neither a base nor an acid. For example, pure water is a neutral substance.

Explanation:
lactase is an enzyme that breaks down a sugar found in dairy products known as lactose. Some people are lactose intolerant, and this can be due to not having enough lactase production. People who are lactose intolerant may not feel well after eating foods containing lactose. Illustrate the scenario and describe the relationship between the substrate and enzyme.
Answer
If people with lactose intolerance eat dairy products, the lactose from these foods pass into their intestines, which can lead to gas, cramps, a bloated feeling, and diarrhea.
Some people can have small amounts of dairy without problems. Others have a lot of stomach trouble and need to avoid all dairy products. Many foods, drinks, and digestive aids are available to help manage lactose intolerance.

A chemical reaction produces a molecule in which all of the atoms have a stable configuration. Which molecule could be the product of the reaction?
(1 point)
SiO
PH3
MgBr
KCl2
The product of this reaction is PH3. All of the atoms in PH3 have a stable configuration.
According to the octet rule, atoms are stable when they have two or eight electrons around their outermost shell. A stable configuration is one in which the outermost shell is fully filled with eight electrons.
The reason behind chemical combination is to enable atoms attain this stable configuration. If we look at the compound, PH3, we will notice that phosphorus has eight electrons around its outermost shell while each hydrogen atom has two electrons around its outermost shell hence all of the atoms have a stable configuration.
