The solute will dissolve quicker if the solute is more?
A. shaken.
B. saturated.
C. cooled.
D. settled.
Answer:
A) Shaken is the correct answer
Explanation:
The other three don't fit in with the solution if you think about it. When you shake something with lemonade crystals (Like a lemonade flavor packet in poured in a water bottle) it dissolves faster when you shake it rather than it sit on the bottom for 15 minutes! :) .
Hope this helps! :)

Directions: Record the number of each atom in each molecule, then record the total number of atoms in the molecule.
Atoms are the individual particles that make up all matter, while molecules are formed when atoms combine together through chemical bonding. There are 6 atoms in NH₄Cl and 5 atoms in CaClO₃.
Atoms are the basic building blocks of matter. They are the smallest units of an element that retain the chemical properties of that element. Atoms consist of a nucleus containing positively charged protons and neutral neutrons, surrounded by negatively charged electrons in energy levels or shells.
Molecules, on the other hand, are formed when two or more atoms chemically bond together. They can be made up of atoms of the same element or different elements. Molecules can exist as discrete units and can have distinct chemical and physical properties. Examples of molecules include water (H2O), carbon dioxide (CO2), and glucose (C6H12O6).
Therefore, there are 6 atoms in NH₄Cl and 5 atoms in CaClO₃ as listed in the table attached.

As part of a lab experiment, Tasha drops a metal cube into a beaker of water, as shown in the figure below. heat transfer After energy in the form of heat transfers between the substances, what is the final temperature of the water? Group of answer choices The final temperature is 25 °C because there is more water than metal. The final temperature is 50 °C because the metal warms the water to the temperature of the metal. The final temperature is between 25 °C and 50 °C because most of the thermal energy is lost to the air around the substances. The final temperature is between 25 °C and 50 °C because energy is transferred from the metal to the water.

Explanation:
Calculate the percent composition of chlorine in methyl trichloride, CHCl3.
Answer:
Chlorine --> 89%
Explanation:
Step 1) Add each element's amu up to get the total mass of the compound.
12.011+1.008+3(35.453) = 119.378.
Step 2) Divide the total mass of chlorine by the total mass of the compound.
3(35.453) = 106.359
106.359/119.378 = 0.8909430548.
Step 3) Now multiply by 100 to get the percentage.
0.8909430548*100 = 89.09430548%
Step 4) Estimate and submit your answer
89.09430548% estimates to 89%
What is a limiting reagent? A.) The reactant that is used up first in a reaction B.) The reactant that is used the least reactive in a reaction C.) the reactant with the smallest coefficient in the equation D.) the reactant with the largest coefficient in the equation
Answer: A.) The reactant that is used up first in a reaction
The reactant that is totally consumed during a reaction, or the limiting reagent, decides when the process comes to an end. A limiting reagent is the reactant that is used up first in a reaction. Therefore, option A is correct.
What is a limiting reagent?A reactant that is completely consumed at the end of a chemical reaction is known as the limiting reagent. Since the reaction cannot proceed without this reagent, the amount of product that can be produced is constrained.
The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.
The terms limiting reagent and limiting agent may also be used to describe the limiting reactant.
Thus, option A is correct.

A bond formed between a fluorine, F, atom and a fluorine, F, atom is likely to be____
A
ionic bond
B.
polar covalent
C
nonpolar covalent
D
alloy
Answer:
c) non polar Covalent
Explanation:
this is a molecule formed by atoms of the same element . they both have similar electronegativities and thus cancel out . This makes it a perfect Covalent molecule . The fact that it's a symmetrical molecule makes it non polar. a symmetrical molecule is a molecule formed by the overlap of orbitals of two atoms of the same element ( that is to say , there's no dipole )
Use the chart to determine which pair of atoms has the greatest difference in electronegativity.
A. Ca – Cl
B. H – Cl
C. Fe – Cl
D. P – Cl

how many moles are equal to 89.23g of calcium oxide?
mass of calcium oxide equals 89.23 g
molar mass of calcium oxide equals 56 G / Mole
the formula which is used as much of CaO equals molar mass of CaO
now put all of the Given values in this formula, we would get the moles of calcium oxide.
moles of CaO= 88.23g over 56g/mole which would get you 1.593 moles

The terms distance and displacement are used by scientists to describe very specific differences between an object's initial position and its final position. Describe a situation in which the distance traveled is great but the displacement is zero.
Explanation:
Distance is the total length of path one travels.
Displacement is the distance between the initial and final position.
For example, if your classroom is located 200m from your dormitory, you walk to class and back to your dormitory, your distance is 200m + 200m = 400m;
Your displacement is 0m. Your initial and final position is the same so no displacement.
A gas occupies 4.31 liters at a pressure of 0.755 atm. Determine the volume if the pressure is increased to 1.25 atm. (Boyle)
Answer:
2.60 LExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
From the question we have
[tex]V_2 = \frac{4.31 \times 0.755}{1.25} = \frac{3.25405}{1.25} \\ = 2.60324[/tex]
We have the final answer as
