Answer:
the transfer of energy because eating is gaining energy from a source, so the energy from that source is being transfer to the animal.
The transfer of energy is achieved when eating and feeding exists. Chemical processes may emit or absorb chemical energy.
What is energy?The ability of a physical process to carry out work is known as energy. It's crucial to remember that simply because energy exists doesn't indicate that it is always ready to do tasks. Thermal energy, sometimes known as heat, is generated when atoms or molecules move. It may be thought of as temperature-related energy.
This energy results from the location of an item. For instance, a ball resting on a table possesses potential energy in relation to the ground because of the influence of gravity. Chemical processes may emit or absorb chemical energy. It is created by atoms and molecules establishing or breaking chemical bonds.
Therefore, the transfer energy is achieved when eating and feeding exists.

Predict the approximate molecular geometry of a formaldehyde molecule:
Answer:
trigonal planar geometry
Explanation:
The molecule, formaldehyde , has three regions of electron density around the molecule. The carbon atom is the central atom in the molecule of formaldehyde.
Recall that each bond around the central carbon atom in formaldehyde- both single and double are counted as a single region of electron density. Molecules having three regions of electron density around the central atom have a trigonal planar geometry.

Consider the data [X] [Y] [Z] initial rate M M M M · s −1 Exp 1 0.30 0.20 0.35 0.210 Exp 2 0.60 0.10 0.70 0.420 Exp 3 0.60 0.20 0.70 0.420 Exp 4 0.60 0.40 0.35 0.105 What is a correct rate law for the reaction?
Answer:
Rate = k [X]⁻¹ [Z]²
Explanation:
[X] [Y] [Z] initial rate M M M M · s −1
Exp 1 0.30 0.20 0.35 0.210
Exp 2 0.60 0.10 0.70 0.420
Exp 3 0.60 0.20 0.70 0.420
Exp 4 0.60 0.40 0.35 0.105
In Experiment 2 and 3 where the concentrations of Y and Z were constant, doubling the concentration of Y had no effect on the rate of the reaction. This means, that the rate of the reaction is zero order with respect to Y.
In experiment 3 and 4, dividing the concentration of Z by 2, causes the rate of the reaction to decrease by 4. This means the rate of the reaction is second order with respect to Z.
In experiment 1 and 4, doubling the concentration of X, causes the rate of the reaction to decrease by half. This means that X has an order of -1 with respect to the rate of the reaction.
The rate expression is given as;
Rate = k [X]⁻¹[Y]⁰[Z]²
Rate = k [X]⁻¹ [Z]²

What is the volume at STP of 3.44 x 1023 molecules of CO2
gas?
a 25.1L
b 39.2 L
С
12.8 L
d 15.7 L
Answer:
C. 12.8 liters.
Explanation:
The Standard Temperature and Pressure (STP) of a gas are 273.15 K and 100 kilopascals. From Avogadro's Law, a mole of carbon dioxide contains [tex]6.022 \times 10^{23}[/tex] molecules. If we suppose that carbon dioxide behaves ideally, then the equation of state for ideal gas is:
[tex]P\cdot V = n\cdot R_{u}\cdot T[/tex] (1)
[tex]P\cdot V = \frac{r\cdot R_{u}\cdot T}{N_{A}}[/tex] (1b)
Where:
[tex]P[/tex] - Pressure, measured in pascals.
[tex]V[/tex] - Volume, measured in liters.
[tex]r[/tex] - Amount of molecules, no unit.
[tex]N_{A}[/tex] - Avogadro's number, no unit.
[tex]R_{u}[/tex] - Ideal gas constant, measured in pascal-liters per mole-Kelvin.
[tex]T[/tex] - Temperature, measured in Kelvin.
If we know that [tex]P = 100000\,Pa[/tex], [tex]r = 3.44\times 10^{23}[/tex], [tex]N_{A} = 6.022\times 10^{23}[/tex], [tex]T = 273.15\,K[/tex] and [tex]R_{u} = 8.314\times 10^{3}\,\frac{L\cdot Pa}{mol\cdot K}[/tex], then the volume of carbon dioxide at STP is:
[tex]V = \frac{r\cdot R_{u}\cdot T}{N_{A}\cdot P}[/tex]
[tex]V = \frac{(3.44\times 10^{23})\cdot \left(8.314\times 10^{3}\,\frac{L\cdot Pa}{mol\cdot K} \right)\cdot (273.15\,K)}{(6.022\times 10^{23})\cdot (100000\,Pa)}[/tex]
[tex]V = 12.972\,L[/tex]
Therefore, the correct answer is C.

which of the following indicates the cathode rays has a large charge to mass ratio?
Answer:
Gggg
Explanation:
The indication of the cathode rays that has a large charge to mass ratio is there were deflected towards a positive electrode. The correct option is b.
What are cathode rays?Cathode rays are the rays that move through the negatively charged electrode the cathode charge to the positively charged electrode which is the anode charge in a vacuum tube.
These rays travel through a pipe in a straight line with speed when there is voltage is applied. They are also called electron beams. There is a cathode ray tube, CRT, which is a vacuum tube on which cathode rays travel.
So, the correct option will be for the cathode rays would be deflected towards a positive charge anode.
Therefore, the correct option is b, there were deflected towards a positive electrode.

Describe the similarities and/or differences between heating and burning the magnesium metal. Did either heating or burning produce a chemical change?
Answer and Explanation:
Heating the magnesium metal is a physical change because after the process, the magnesium metal is still magnesium metal and no other substance is formed. When we heat the metal, we tranfer energy and the temperature is raised. It could include the melting of the metal, which is a change in the state of matter, but it is still a physical change because no chemical reactions occur.
Burning the magnesium metal is a chemical change because it involves the reaction with O₂ to form a different compound (a magnesium oxide).
