If you have 3.62 moles of Tin (Sn), how many grams do you have?
Answers
Answer:
Use molar mass:)
Explanation:
3.62 mol of Sn ([tex]\frac{118.7gramsSn}{mol}[/tex])=429.694
Since 3.62 has 3 sig figs, limit 429.694 to 3
= 430
A group of earth science students were investigating in the laboratory. They took granite rock and limestone samples and massed
them on a balance. Then, students placed the rock samples in closed plastic vials. The students shook them vigorously for thirty
minutes. Students then massed the rocks again. What is the dependent variable in this experiment?
es )
A)
Why does granite rock break down more quickly?
B)
How do rocks interact during mechanical manipulation?
C)
Which rock type changes more due to physical weathering?
D)How does granite change shape after mechanical breakdown?
Answers
Answer:
Which rock type changes more due to physical weathering?
Explanation:
A dependent variable is the effect obtained by manipulating a cause. Hence, when you are carrying out an experiment, the variable that you manipulate is the independent variable while the effect that it produces is the dependent variable.
Therefore, when the both rock samples are shaken, the mass after shaking shows the extent to which the rock samples break down after a physical weathering process. This is the dependent variable because the extent of physical breakdown depends on the type of rock.

Write about similarities and the differences of the plant and animal cell
Answers
Answer:
Mark me as brainliest pls
Explanation:
similarities: Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal element
differences: A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. ... Animal cells simply have a cell membrane, but no cell wall.

An element that is commonly found in household materials, malleable, and a good conductor of heat and electricity. They say it is not very reactive and is very similar to the other elements in its group as an alkali metal.
What is an alkali metal ?All the elements listed in column 1A of the periodic table—hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium—are classified as alkali metals. The fact that all of these metals contain one electron in their outermost layer of electrons binds them together.
The production of paper, detergents, and soap all need sodium hydroxide. In addition to being used as the electrolyte in alkaline, Ni-Cd, and Ni-MH batteries, potassium hydroxide is also used by farmers to make acidic soil more alkaline so that plants would grow better in it.
Vinegar, hydrochloric acid, and sulfuric acid are a few examples of the H = ion-containing compounds referred to as acids. Alkalis are a class of substances that feel soapy and contain the OH = ion.
Thus, option D is correct.

In order for the process to be endothermic, the energy required to break the lattice has to be _______ than the energy released as the ions go into solution.
a. Greater
b. Less
Answers
Explanation:
I honestly believe the answer is greater
If the energy required to break the lattice is less than the energy released as the ions go into solution, then the dissolution of solute is endothermic.
An endothermic reaction is one in which energy is absorbed. This implies that the energy change of the reaction is positive.
Now, if the energy required to break the lattice is less than the energy released as the ions go into solution, then the process is endothermic and energy is absorbed.

A 0.50 M solution of H Br is to be poured into a beaker that initially contains 50 g of solid CaCO3. Determine the volume of H Br that will be needed to completely react with the 50 g of solid CaCO3.
Answers
Answer:
2 liters of HBr is needed to completely react with the 50 g of salt.
Explanation:
First of all, we determine the reaction:
2HBr + CaCO₃ → CaBr₂ + CO₂ + H₂O
We need to calculate, moles of carbonate in order to state the stoichiometry (1:2)
50 g . 1mol / 100.08g = 0.499 mol
1 mol of salt need 2 moles of acid to react, according to stoichiometry
Then, 0.499 moles of salt, will react with (0.499 . 2)/1 = 0.999 moles
As we have the [HBr], we can calculate the volume.
M = mol/L → we replace → 0.50 mol/L = 0.999 mol /L
L = 0.999 mol/0.50 mol → 1.99 L ≅ 2L
