A 5 g sample of pure gold has a density of 19.3 g/ml. Your friend purchased a gold ring that was made of 25 g of pure gold. What is the density of the ring?
Answers
Answer:
96.5 g/ml
Explanation:
If 5g is 19.3 then 25g is 19.3x5 which is 96.5 g/ml
The 5 g gold sample is having a density of 19.3 g/ml. The density for 25 g pure gold will be 96.5 g/ml.
What is density?Density of a substance is the measure of its mass per unit volume. It describes how closely the particles are packed within the substance. Density is dependant on bond type, temperature, pressure etc.
The density is the ratio of mass to the volume. The density of the 5 g sample is given 19.3 g/ml . Then the density for the mass 25g is determined with the relation as shown here:
M 1 D2 = M2 D1.
D2 = M2 D1/ M1
Now, the density of the 25 g gold ring is calculated as follows:
(25 × 19.3 )/5 = 96.5 g/ml.
Therefore, the density for the gold sample with 25 g mass is 96.5 g/ml.

How is density different from weight and mass?
Answers
Hello there!
How is density different from weight and mass you say? It's simple!
1. Unlike weight, density is composed of mass and volume.
2. By dividing the mass over the volume, you can determine an object's density, while weight is the product of mass and gravity.

Answers
Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis are the proper phases of the cell cycle. The series of actions that take place between the development of a mother cell and the production of two daughter cells is known as the cell cycle.
Interphase and cell division are the two main stages. The phase of the cell cycle known as interphase is when the cell develops and gets ready to divide. The initial stage of cell division, known as prophase, occurs when the nuclear envelope separates and the chromosomes condense.
The second stage of cell division, known as metaphase, is when the chromosomes align in the centre of the cell. The third stage of cell division, known as anaphase, is when the chromosomes split and migrate to the opposing poles of the cell.

2.)B
Explanation:
The total mass of products obtained in the reaction; CaCO3→CO2+CaO is 30 grams. Given the reaction; Fe+O2→Fe2O3, atoms of Fe and O2 are rearranged during the reaction. During a chemical reaction, mass is conserved. Given the reaction NaHCO3+HC2H3O2→NaC2H3O2+H2O+CO2, we can see that the atoms of the reactants are regrouped during the reaction. Given the reaction 2H2+O2→2H2O, there are four atoms of hydrogen before and after the reaction.
According to the law of conservation of mass, atoms are neither created nor destroyed in a chemical reaction. Similarly, mass is neither created nor destroyed.
This means that the number of atoms of each element before and after the reaction must remain the same. A chemical reaction only involves the rearrangement of atoms in reactants to form products.
The total mass of reactants must be equal to the total mass of products according to the law of conservation of mass.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.
What type of energy is torque?
A
wind energy
B
rotational energy
C
potential energy
D
chemical energy
Answers
Answer:
I think It's B. rotational energy . Or if not then A. wind energy
Explanation:
I searched up the definition of Torque and it said "Torque is a twisting force that speaks to the engine's rotational force and measures how much of that twisting force is available when an engine exerts itself." Tell me if I'm wrong. :))
Torque is the rotational type of energy. Therefore, option B is correct.
What is torque?The force that can cause an object to rotate along an axis is measured as torque. Similar to how force accelerates an item in linear kinematics, torque accelerates an object in an angular direction.
The work-kinetic theorem for rotation states that the change in rotational kinetic energy is equal to the sum of all torques operating on a rigid body while it rotates along a fixed axis.
The force that can cause an object to rotate along an axis is measured as torque. Similar to how force accelerates an item in linear kinematics, torque accelerates an object in an angular direction.

When a chemical reaction does not occur, what happens to the atoms of the two substances? Provide an example from Sim as evidence to support your answer.
Answers
An example of this can be seen in the Sim on Amplify, where students can experiment with different chemical reactions. For instance, in the "Chemical Reactions" Sim, students can explore the reaction between iron and sulfur to form iron sulfide. In this reaction, the iron atoms and sulfur atoms combine to form a new compound, iron sulfide, with different properties than the original iron and sulfur. The atoms of the iron and sulfur are rearranged to form new bonds, resulting in the formation of a new substance. This is an example of a chemical reaction, where the atoms of the two substances are rearranged to form a new compound with different properties.
Answer:
Explanation:A chemical response is a chemical transformation in which two chemicals combine to create a third component.
(i) Adding diluted acid to an active metal causes the test tube to heat up and hydrogen gas to escape, which results in the production of heat.
(ii) When diluted hydrochloric acid is added to silver nitrate, AgCl, a white precipitate, results.
(iii) When water is added to quicklime, the mixture boils and produces heat along with a hissing sound.
(iv) Thermal breakdown of mercury oxide - Mercury turns from red to a metallic silver tint as a result of this process.
