Answer:
D
Explanation:
A chemical reaction is a process in which substances undergo a chemical change to form a different
substance. Mixing baking soda and vinegar will create a chemical reaction because one is an acid
and the other a base. Baking soda is a basic compound called sodium bicarbonate while vinegar is a
diluted solution that contains acetic acid (95% water, 5% acetic acid).
There are five signs that indicate a chemical reaction has occurred: odor, energy change, gas
bubbles, precipitate formation, and color change. When any of these changes occur, the reaction is
irreversible and cannot be undone. The reaction occurs once the vinegar is added to the baking
soda. In this reaction, evidence of a chemical reaction is the formation of carbon dioxide gas and gas
bubbles.
There are two separate types of reactions taking place when mixing baking soda and vinegar. The
first is called an acid-base reaction. When the two substances are mixed together, hydrogen ions in
the vinegar react with the sodium and bicarbonate ions in the baking soda. This initial reaction
results in two new chemicals: carbonic acid and sodium acetate.
why cant students opt out of day classes and have the choice to do online rather then being pushed to go to class and end up ditching class and failing for no participation
Answer:
Students are simply not motivated in online classes. They are usually easy A's and are time efficient, but student learning outcomes tend to be lackluster. ... Perhaps the biggest disadvantage of taking an online class is the absence of face-to-face interaction between the teacher and their students. It also doesnt benefit the school which is what most schools really care about.

Lake Superior contains 3.0 x 10^15 gallons of water. How many cubic meters of water are contained in the lake? Express your final answer in scientific notation.
Given that:
Lake Superior contains 3.0 x 10^15 gallons of water
Firstly, let's know that of 1 gallon;
1 gallon = 0.00375 cubic meter
Then, 3.0 x 10 ^15 = 3.0x10^15 x 3.785 x 10 ^-3
= 3 x 3.785 x 10^15-3
= 11.355 x 10 ^12m^3
Therefore, 11.355x10^12 cubic meters of water are contained in the lake.

I am in the middle of taking the test and my best guess on this would be c
Explanation:
Why I say it could be C is because if the person below chose D and it was voted wrong then it cannot be that answer. It can't be because that doesn't make sense. B can be somewhat ruled out due to the fact that they didn't exploit the colonies the colonies did that to them.
In what ways do cultures use land and resources differently than other cultures?
Answer:
The terms land culture or land-based culture are often used in reference to indigenous cultures that view their responsibility as land curators versus landowners. As such, land is also often connected to the identity and spirituality of individuals within the culture.
Cultures use the environment to their advantage as well as the available livestock, for instance, the incans built long mountainous roads that would make a difficult trek for humans carrying goods, therefore they used llamas, a native animal to the province to carry goods for merchants. This technique was hardly used in other civilizations.

Kramer and Jerry moved from New York to Los Angeles in pursuit of becoming actors. They considered all of the apartments in the area of the city they wished to live in and decided to rent one that was to their satisfaction.
Explain how each of the following is related to Kramer and Jerry’s decision to rent an apartment.
- Frontal Lobe
- Foot-in-the-door Phenomenon
Explain how each of the following concepts could be related to Kramer and Jerry’s moving their belongings into the apartment
- Social Loafing
- Cerebellum
- Broca’s Area
Provide an example that explains how each of the following concepts could be related to life for Kramer and Jerry in their new apartment in Los Angeles.
- Normative Social Influence
- Self-Fulfilling Prophecy
The frontal lobe is related to Kramer and Jerry's decision to rent an apartment in order to be the part of the brain responsible for cognitive functions such as memory, problem solving, emotions, etc.
The foot-in-the-door phenomenon relates to Kramer and Jerry's decision to rent an apartment in that this phenomenon is a compliance tactic, which occurs when a small order is placed, in order to encourage compliance with a larger order.
In other words, they visited the apartments in the area of the city where they would like to live and after that visit, they decided to rent one that they liked.
Social Loafing can make moving Kramer and Jerry's belongings to the apartment slower, as this theory is related to less effort in achieving goals when accomplished in a group.
The cerebellum is the part of the brain responsible for coordinating voluntary movement, motor skills, balance and posture, functions that will enable Kramer and Jerry to carry out the work of moving their belongings into the apartment.
The broca's area is the brain area where motor speech is produced, it is responsible for regulating breathing and vocalization during speech, so that communication between them is possible.
Normative social influence occurs when a person adjusts to fit into a group, associated with conformity.
An example of how normative social influence might be related to Kramer and Jerry's life in their new LA apartment could be the set of habits they will acquire while living there, such as physical activity and the use of designer clothing.
Self-fulfilling prophecy corresponds to false expectations about a person or entity, generating adjustments in behavior, perception and communication to match expectations, making it a reality, thus strengthening the belief.
For example, if Jerry and Kramer believe they can't be successful actors in Los Angeles, they skip auditioning to get a role.

to what extent made the natural environment and the demands of pastoral economy influence social organization on Eurasian steppe lands
The social structure of the Eurasian steppe regions was significantly influenced by the natural environment and the needs of the pastoral economy.
The wide grasslands and nomadic way of life in these areas influenced the social structure. Mobility was necessary for nomadic pastoralism to maintain animals, which resulted in social structures that were decentralized and adaptable.
Clan-based kinship networks and tribal ties developed, encouraging cooperation for defense and survival.
Trade routes encouraged cultural interaction and trade, which influenced political federations and alliances.
Because of how important defense and mobility were, leadership was frequently centered around capable military leaders.
Thus, environmental issues in the steppe and the necessity for resource management interacted to create distinct socio-political dynamics that had a lasting impact on governance, migratory patterns, and inter-tribal relations.
