Answer:

Each element within a group has similar physical or chemical properties because of its atom's outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).

Explanation:

Because it has less surface area. This can be applied to something like cooking potatoes. Cooking a larger potato will take longer than a small potato.

n energy-carrying molecule found in all living things' cells. ATP absorbs chemical energy from the breakdown of food molecules and uses it to power other cellular processes.

Explanation:

Hope it helps

ATP is a crucial energy molecule in cells, providing energy for various cellular processes.

ATP, or adenosine triphosphate, is often referred to as the "energy currency" of the cell. It plays a vital role in cellular metabolism by providing energy for various processes. ATP is composed of adenosine and three phosphate groups. The energy stored in ATP is released when the terminal phosphate group is hydrolyzed, forming ADP (adenosine diphosphate) and inorganic phosphate (Pi).

The role of ATP in a cell is multifaceted. Firstly, ATP powers cellular work by providing the energy needed for chemical reactions, such as biosynthesis, active transport, and muscle contraction. It acts as an immediate source of energy that can be rapidly used by the cell.

Secondly, ATP participates in signal transduction and cellular communication. It can be hydrolyzed to ADP and Pi, releasing energy that can activate signaling molecules and enzymes involved in cell signaling pathways.

Furthermore, ATP is involved in maintaining cell homeostasis. It provides energy for processes like ion pumps that maintain the electrochemical gradients across the cell membrane, allowing cells to regulate their internal environment.

Overall, ATP is crucial for the functioning of cells as it serves as an energy carrier, facilitating energy transfer and powering various cellular processes essential for growth, metabolism, and cell survival.

Answer:

24.30

Explanation:

Multiply the relative abundance by the atomic mass of each isotope, add the results together, and divide by 100. Then round to the correct amount of significant figures.

(78.99 x 23.9850) + (10.00 x 24.9858) + (11.01 x 25.9826)/100

24.30 is the average atomic mass (in amu) of element M.

Atomic mass is the quantity of matter contained in an atom of an element.

Multiply the relative abundance by the atomic mass of each isotope, add the results together, and divide by 100. Then round to the correct amount of significant figures.

(78.99 x 23.9850) + (10.00 x 24.9858) + (11.01 x 25.9826)

Answer: There are 36 valence electrons.

Explanation:

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, the valence electrons of C₄H₈O₂ is 32.

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

A valence electron is a negatively charged particle, located in the outermost shell of an atom, that can be transferred to or shared with another atom. To calculate total valence electrons in C₄H₈O₂, we need to add the individual valence electrons of each element.

Valence electrons of C₄H₈O₂= {valence electrons of C×4}+{valence electrons of H×4}+{valence electrons of O×2}

Valence electrons of C₄H₈O₂= {4×4}+{1×4}+{6×2}

Valence electrons of C₄H₈O₂=32

Therefore, the valence electrons of C₄H₈O₂ is 32.

Answer:

5,000

Explanation:

When rounding to the thousands place, you look at the digit in the hundreds place, if the digit is less than 5 you round down. For example if the number was "4,456," we would round to "4,000." But, since the digit in the hundreds place is 7, which is greater than 4, you round up to "5,000."

Answer:

As heat is added to solid water, the temperature increases until it reaches 0 °C, the melting point. At this point, the phase change, added heat goes into changing the state from a solid to liquid. Only when this phase change is complete, the temperature can increase.

hope this helps

Heat is responsible for the change of phase from solid to liquid state.

A phase change from solid to liquid occur in a substance by heating of that substance because the bonds present between solid particles can be broken down with the help of heat energy.

When the bond is heat at the temperature on which it is broken down, the solid particles are converted into liquid substance so we can conclude that heat is responsible for the change of phase from solid to liquid state.

The color absorbed is the complementary color to the color we perceive.

The color absorbed by an object and the color we perceive are complementary. All objects that we see have different colors. The color we see is always opposite to the color absorbed by the object in the color wheel.

Hence, the color wheel can be used to show the relationship between the color perceived and the color absorbed by the object. The color absorbed is the complementary color to the color we perceive.

Explanation:

Both theoretical and actual yields would be needed to calculate percent yield.

The percent yield of a reaction is defined as the ratio of the actual yield to that of the theoretical yield. It can be mathematically expressed as:

percent yield = actual yield/theoretical yield x 100%

The actual yield is the amount of a specific product produced from a reaction while the theoretical yield is the stoichiometric amount of the same product.

Answer:

cm^3 —> dm^3

divide by 1000

159.5 — Mr of CuSO4

n (moles in mol) = c (concentration in mol/dm^3) * v (volume in dm^3)

0.100 mol of CuSO4 dissolved in 0.5dm^3 of water

calculate for mass of CuSO4 dissolved in 0.03dm^3  (30cm^3) of the solution

n = m/Mr

m = n*Mr

if 0.1 mol is dissolved in 0.5 dm^3 of water

0.5/0.03 ≈ 16.66666667

0.1 = 0.05

0.1 / 16.66666667 = 0.006

0.5 / 16.66666667 = 0.03

0.006 (mol of CuSO4) = 0.03 (dm^3 solution)

0.006 * 159.5 = 0.957 g

I think this is the answer

The mass copper sulphate CuSO₄ in 30ml solution is 957.6g.

To determine the mass of copper sulphate in the given solution, compare both the molarity given  

M₁V₁=M₂V₂

n₁/V1=n₂/V2

0.1/0.5=n₂/30         cm³=ml

n₂=6 moles

6×159.5=957.6g

Multiply the calculated moles with the relative mass/molecular mass to get the mass of CuSO₄.

hence, the mass of CuSO₄ is 957.6g

Answer: The information about sequential order of the event occurred in the past can be obtained by using only relative dating method.

Explanation:

Relative dating method doesn’t give information about when it happened. It provides sequential order of the events. It is the art of deciding the overall happening of past occasions (i.e., the age of an item in contrast with another), without fundamentally deciding their outright age (for example evaluated age).
