Answer:
The answer is 0.0092705727916105. We assume you are converting between moles Ag and gram.
Explanation:
Answer:
97.2 g Ag
Explanation:
Molar mass of Ag = 107.86 g/mol
0.901 moles Ag x (107.86 g Ag/ 1 mol Ag) = 97.2 g Ag
Moles cancel and you are left with grams of Ag. Multiply 0.901 by 107.86 to find grams of Silver.

The true statements are - Cells come in different sizes and shapes, some organisms are made of just one cell and most cells are too small to see with the eye. Thus, the correct options are options A, C and E.
Cells are the basic structural and functional units of life. They are the smallest entities that can carry out the fundamental processes necessary for an organism's survival.
Cells are enclosed by a cell membrane, which separates the internal components from the external environment. Inside the cell, various parts perform specific functions, such as energy production, protein synthesis, and storage of genetic material.
Cells can be categorized into two broad types: prokaryotic cells, which lack a nucleus and eukaryotic cells, which have a nucleus.
Thus, the ideal selection is option A, C and E.

What mass of calcium bromide is needed to prepare 150.0 mL of a 3.50 M solution? (Assume that the molecular weight of CaBr2 is 200.618 g/mol)
Answer:
105g
Use the following formula to calculate the mass of calcium bromide that is needed:
volume of solution × molar concentration × molar mass = mass of solute
The result is 105 g, which has three significant figures, because the term with the least precision (3.50 M) has three significant figures.

Answer: Rubbing
Explanation: The lost atoms never come back because after rubbing, the molecules are shaking back and forth faster than they were billions of atoms. When molecules break apart or come together, that's called a nitrogen and oxygen molecules are lost this way too, but since their average velocity is so simplicity , that is missed by people who don't study physics.
When a substance is in the liquid state, how are the particles of that substance
behaving
Answer:
In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.

can someone summarise the speed of sound for me? :) I'm not rly good at science ahah, anyone good at it.?
increasing temperature:
causes particles to ....?
which means that sound will travel...?
making something more solid:
causes particles to ....?
which means that sound will travel...?
Explanation:
The speed of sound is the distance that sound waves travel in a given amount of time. ... Generally, sound waves travel most quickly through solids, followed by liquids, and then by gases. For a given medium, sound waves travel more slowly at lower temperatures.
Answer:
increasing the temperature will also increase the number of collisions between molecules per unit time. Which means molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly.
Slow down, but generally not move from there place. Which means molecules at a lower temperature have less energy, meaning sound waves can't travel through in a solid.
Explanation:
Sound waves can only travel in space if there are enough particles around to transmit the energy in the wave from the source thus meaning more kinetic energy more sound waves being able to quickly get through

Which activity uses water for both recreational and industrial purposes?
machinery cooling
waterskiing
irrigation
fishing
Answer:
D. Fishing.
Explanation:
Fishing refers to an activity which typically involves catching fishes for both recreational (sports or hobby) and industrial (feeding or sales) purposes. In finishing, the fishes are caught from water such as a pool, lake, river etc. through the use of fishing nets, rod and lines and fish hooks.
Basically, when fishing is done with family members, peers or even individually such as on a vacation, sports competition and pleasure, it is mainly considered to be for recreational purposes.
However, when fishing is done on a commercial basis such as selling them consumers, it is considered to be for industrial purposes.
Hence, fishing is an activity which uses water for both recreational and industrial purposes.

Many enzymes are inhibited irreversibly by heavy metal ions such as Hg2+ , Cu2+ , or Ag+ , which can react with essential sulfhydryl groups to form mercaptides. Enz−SH+Ag+⟶Enz−S−Ag+H+ The affinity of Ag+ for sulfhydryl groups is so great that Ag+ can be used to titrate −SH groups quantitatively. To 10.0 mL of a solution containing 3.4 mg/mL of a pure enzyme, an investigator added just enough AgNO3 to completely inactivate the enzyme. A total of 0.134 μmol AgNO3 was required. Calculate the minimum molecular weight (????r) of the enzyme.
Answer:
Explanation:
one mole of AgNO₃ reacts to inactivate one mole of enzyme
mg of enzyme in 10 mL = 3.4 x 10 mg = 34 mg .
required AgNO₃ = .134 x 10⁻⁶ mole
.134 x 10⁻⁶ mole AgNO₃ is required for inactivating 34 mg of enzyme
1 mole of AgNO₃ will be required for inactivating 34 / (.134 x 10⁻⁶ ) mg of enzyme
= 253.73 x 10⁶ mg of enzyme
= 253.73 x 10³ g of enzyme
Mol weight of enzyme = 253.73 x 10³ .
how did the ancient greek understanding of atomic particles likley influence dalton research?
Answer:
The Greeks called these particles atomos, meaning indivisible, and the modern word “atom” is derived from this term. Democritus proposed that different types and combinations of these particles were responsible for the various forms of matter.
Explanation:
hope it helps
The idea of indivisibility of the atom upheld by Dalton was largely derived from early Greek philosophers.
John Dalton was the first scientist to begin an empirical study of atomic theory. Before this time, all that was known about the atom were largely based on the speculation of Greek philosophers.
However, one recurring theme among Greek philosophers is that atoms are indivisible. This idea that atoms are indivisible became a very strong pivot of the Dalton's theory of the atom.

Why do we believe that these strange quantum laws are correct? Group of answer choices Experiments show they're sometimes right. There haven't been any experiments done on them because they can't be tested, so we just think they're right. In experiment after experiment, they're always right. We actually don't believe they're right, we just like to talk about them.
Answer:
In experiment after experiment, they're always right
Explanation:
In science, nothing is accepted unless it can be supported by empirical evidence, this includes the quantum laws.
A plethora of experiments have confirmed these quantum laws to be correct and reliable.
Hence, all the quantum laws are backed up by plenty scientific evidence that show that the laws are indeed correct.
a prospector finds 39.39 g of gold. How many atoms of gold does he have
Answer:
the answers is 1.204×10/23
Explanation:
idek
According to Avogadro's number, there are 1.204 × 10²³ atoms in 39.39 g of gold.
To determine the number of atoms in 39.39 g of gold, we need to use the Avogadro's number, which is equal to 6.022 × 10²³ atoms/mol.
First, need to convert the given mass from grams to moles by dividing it by the molar mass of gold, which is 196.967 g/mol.
[tex]\dfrac{39.39}{196.96}\\=0.19999[/tex] moles
Now, we can use Avogadro's number to find the number of atoms:
[tex]0.19999\times6.023\tims10^2^3\\=1.204\times10^2^3[/tex]
Therefore, the prospector has 1.204 × 10²³ atoms of gold.
