Sarah adds 10 g of baking soda to 100 g of vinegar. The mixture begins 20
to bubble. When the bubbling stops, Sarah finds the mass of the resulting
mixture. She determines its mass is 105 g. The data she collected is in the
table. Does this follow the law of conservation of mass? Explain.​

Answers

Answer 1

Answer:

Yes, the reaction between baking soda and vinegar follows the law of conservation of mass.

Explanation:

The table and data was not attached to the question.

When baking soda and vinegar are mixed together, a chemical reaction occur resulting to release of gas (carbon dioxide gas)

Law of conservation of mass states that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products.

That is mass of reactant = mass of product = 100g + 10g = 110g

Sarah got 105g as product because a gas of mass 5g was released during the reaction.

Sarah found the mass of the resulting

mixture without including the mass of the released gas.

A way to account for the mass of the gas is if the experiment is done in a closed system like zip lock bag to collect and account for the mass of the gas.

When this is done, the law of conservation of mass would be proven.

d) Zygote travels down the fallopian tube toward the uterus

Answers

Number 1 is C
And im not sure about the rest :(

Storing hormones, smooth and cardiac muscles are the correct answers.

Storing hormones is not function of skeleton system. Skeleton system protects internal organs such as heart, kidney and lungs etc. It is also responsible for the movement of the muscles as well as produces blood cells because of the presence of bone marrow.

Smooth and cardiac muscles can contract without nervous system stimulation because they are involuntary Muscle which is beyond the control of the nervous system so we can conclude that storing hormones, smooth and cardiac muscles are the correct answers.

Jacque could measure the height of the rock layer.

Jacque could check if the rock layer has fossils in it.

Jacque could look at the color of the surrounding rock layers.

Jacque could chip off a chunk of rock from the rock layer and smell it.

Answers

Answer:

Check if the rock layer has fossils in it.

Explanation:

The rock layer from the inside out and the fossils will tell you how old the rock is.

Jacque could check if the rock layer has fossils in it, as the presence and types of fossils can often provide clues about the environment in which they were formed.

What can a rock layer tell about the environment?

To investigate what the environment was like when a rock layer was deposited, there are several approaches that can be taken:

Look for clues in the rock layer itself: The rock layer itself can often provide clues about the environment in which it was formed. For example, the presence of certain minerals or fossil types can indicate the presence of specific conditions, such as warm or cold temperatures, or a marine or terrestrial environment.

Examine the surrounding rock layers: The rock layers above and below the rock layer of interest can provide additional context and clues about the environment. For example, if the surrounding layers are sedimentary rocks, such as sandstone or shale, it may indicate that the area was once covered by water.

Use rock dating techniques: As mentioned earlier, techniques like radiometric dating and relative dating can help determine the age of a rock layer and provide insight into the environment that existed at the time it was formed.

Conduct additional analyses: Depending on the type of rock and the questions being asked, it may be possible to conduct more detailed analyses, such as chemical or isotopic analyses, to gather further information about the conditions under which the rock formed.

Consider the current location of the rock layer: The current location of the rock layer can also provide clues about the environment in which it was formed. For example, if the rock layer is found in a mountain range, it may have formed in a tectonically active area, while a rock layer found in a flat, low-lying area may have formed in a more stable environment.

Maple and oak trees are both deciduous angiosperms, so the wood each produces is classified as a hardwood. However, the difference between maple and oak wood is significant, and it would be difficult to mistake one for the other. All species of oak display a distinctive well-defined grain pattern whereas the maple wood grain tends to be creamy white with little visible grain. The differences don't stop there, but to really appreciate them, it's important to realize that within the broad category defined by oak is a subset of species that differ significantly from each other.
