The table shows mass and volume measurements in an investigation that involves vinegar and baking soda, both before and after the chemical reaction.
What evidence supports the law of conservation of mass?
The mass remains constant before and after the chemical reaction
The volume of the products is more than the volume of the reactants, so it does not support the law of conservation of mass.
The mass of the gas is more than the mass of the baking soda, so the mass is constant
The density of the products is less than the reactants, so the mass is constant.
Answer:
mass will be less
Explanation:
A chemical reaction takes place when vinegar and baking soda are mixed. One of the new substances formed is carbon dioxide gas. If the carbon dioxide gas is contained, the mass of the substances will stay the same according to the Law of Conservation of Mass. If the gas is allowed to escape, the mass will be less

Most metals are too …………… to exist on their own in the ground. Instead they exist combined with other elements (typically o……….. Or sulphur) as ……………….. Called …………. A few metals are so ……………….. That they exist uncombined, as ……….Metals e.G. Gold, ………………..
Answer:
Reactive
oxygen
compounds
Ores
Unreactive
Pure
Silver
Explanation:
The activity series shows the order of reactivity of metals. Metals that are high up in the series are highly reactive. These highly reactive metals will not exist alone in the ground. They combine with elements such as oxygen, sulphur, etc to form ores.
Other metals that are found much lower in the activity series are largely unreactive. They exist in the ground as pure metals, examples include silver and gold

b. What two things would need to happen for your hypothesis to eventually become a theory? Look back over the definition of a theory. (2 points
Answer:
A scientific theory is a broad explanation for events that is widely accepted as true. To become a theory, a hypothesis must be tested over and over again, and it must be supported by a great deal of evidence. People commonly use the word theory to describe a guess about how or why something happens.

(06.06 MC) Which of the following correctly describes the relationship depicted in the diagram below? The image shows a Venn diagram with three interconnected circles: Dermal Tissue, Vascular Tissue, and Ground Tissue. Parenchyma is in the portion where all three circles intersect. Xylem and phloem is under Vascular Tissue. Collenchyma and sclerenchyma are under Vascular Tissue and Ground Tissue. the relationship between different plant hormones and their functions the completed plant tissues and the cells that initiate their growth the types of cells and the tissues in which they can be found in a plant the differences between plant structures and the hormones they produce
Answer:
The types of cells and the tissues in which they can be found in a plant
Explanation:
The diagram is clearly comparing tissues as that is what the big labels are. Add to that that the things being compared in the diagram are types of cells. Something you should be able to easily identify since you're taking the test.
The Diagram and photo of the correct answer if anyone was wondering:

Plants perform photosynthesis but not cellular respiration
Answer:
Plants perform both photosynthesis and cellular respiration
Explanation:
Although plants use photosynthesis to make glucose, they still need energy to break down glucose. Plus, plants have mitochondria too, where cellular respiration occurs.

What are some disadvantages of fossil fuels?
A Fossil fuels deplete Earth of its historical materials.
B Fossil fuels are nonrenewable and may cause pollution.
C Fossil fuels are relatively cheap to produce and easy to use.
D The use of fossil fuels depletes our forests of resources.
Answer:
B. Fossil fuels are nonrenewable and may cause pollution.
Explanation:
Fossil fuels are nonrenewable, meaning that they cannot be replenished sustainably. So, eventually, we will run out of them because they cannot be renewed.
Another disadvantage of fossil fuels is that they cause pollution. For example, the gasoline that is used by cars creates significant amounts of pollution every year.
Pollution is created by cars, factories, homes, and everything else that uses fossil fuels.
So, the correct answer is B, fossil fuels are nonrenewable and may cause pollution
Sally is pregnant and worried that she might be Rh incompatible with her
unborn child after remembering what she learned in her high school
biology class. Sally knows she is Rh negative (the recessive phenotype) and
her husband is Rh positive, but is heterozygous. What chance do they have
of their potential child being Rh positive?
Answer:
The Rh- allele is recessive. So sally is Rh-Rh- and her husband is Rh+Rh-.
The possible genotypes for Punnet's square are: Rh+/-,Rh+/-,Rh-/-,Rh-/-
So the chance to have an Rh+ child is 50%
