Explanation:
An 80 gram sample of a radioisotopes decayed to 40 grams in 3 days how many grams of the original sample would remain after 9 days
Answer: 10 grams
Explanation: Original sample is 80 gram and every three days half of its composition decays so 80 down to 40 in the first 3 days, 20 in the next three days, and 10 in the last three days
What are the flocculation basins?
Answer:
Flocculation is the operation in which the coagulated water must be gently mixed at a propeller speed of 15 to 20 rpm to promote the growth of the floc. ... The flocculation basin often has a number of compartments with decreasing mixing speeds as the water advances through the basin.

Is the trend in reactivity for nonmetals the same as the trend in reactivity for metals?
Answer:
no
Explanation:
In Non-metals
Period - reactivity increases as you go from the left to the right. Group - reactivity decreases as you go down the group
In Metals
Reactivity increases down a group because as nuclear shielding increases and the nucleus' hold on the valence electron weakens, therefore it is easier to remove valence electrons.
Releases energy in the form of ATP

During a chemical or physical change, energy may be...
a. created into another form
b. destroyed and reinvented into another form
c. converted into another form
d. disappeared
Answer: C: Converted into another form
Explanation: pues es esa calale y si va a hacer
During a chemical or physical change, energy is converted to another form. Energy cannot be created or destroyed. During a chemical reaction, physical change the energy and mass are conserved.
What is law of conservation of energy ?According to the law of conservation of energy energy can neither be crated nor be destroyed. Hence, the total energy of a system is always conserved.
However, energy can be transformed from one form to the other. Therefore, the energy lost in one form is gained in another form. For example, in all electrical devices, the electrical energy is converting to other forms of energy such as light, thermal , mechanical etc.
Similarly, during a chemical reaction, the energy released by a reaction system is equal to the energy absorbed by other reacting system. Similarly in electrochemical cells the chemical energy is converting to electrical energy.

1. How much heat is required to heat 22 grams of Aluminum from 15 °C to 49° C
Answer:
670.956
Explanation:
You can use this equation to solve for heat :
Q = m * c * ΔT
Q represents the heat
m represents the mass in kilograms
c is the specific heat. For aluminum, it's 897
ΔT is the change in temperature, so, 49 - 15 which is 34
Plug in the numbers and you get this :
Q = 0.022 * 897 * 34
Q = 670.956 Joules
Please if you don't know don't answer
Answer:
Mass = 50kg, a = 20m/sec^2
F = MA
F = 50 * 20
F = 1000N
F = MA
650 = M * 10
M = 650/10 = 65kg
The phenomenon of weightlessness occurs when there is no force of support on your body. when your body is effectively in free fall, accelerating downward at the acceleration of gravity, then you are not being supported.
F = Gm1m2/distance^2
F = 6.6726* 10 ^-11 * 70 * 5.98 * 10^24/(6.38 * 10^6)^2

When glucose is totally oxidized to CO2 and H2O, how many ATP molecules are made by oxidative phosphorylation out of a maximum yield of how many ATP molecules?
Answer: 26 out of 30.
Explanation:
Out of 30 ATP molecules, 26 are produced from maximum oxidative phosphorylation production. Two more come from glycolysis and two more are from the citric acid cycle.
To power other cellular processes, ATP captures and releases chemical energy obtained from the breakdown of food molecules.
how is the strength of an acid affected by the number of hydrogen ions it contains
Answer:
The greater the number of hydrogen ions, the increase in the acid strength.
Explanation:
Hydrogen ions determine the pH of the acid, greatest number of hydrogen ions give the pH value below 4 hence strong acid, and least number of hydrogen ions give a pH value above 4 but less than 7 hence a weak acid

A ball is moving at a speed of 6.70 m/s. If the kinetic energy of the ball is 3.10 J, what is the mass of the ball?
Answer:
0.14 kgExplanation:
The mass of the ball can be found by using the formula
[tex]m = \frac{2k}{ {v}^{2} } \\ [/tex]
v is the velocity
k is the kinetic energy
From the question we have
[tex]m = \frac{2(3.10)}{ {6.70}^{2} } = \frac{6.20}{44.89} \\ = 0.138115...[/tex]
We have the final answer as

3 main types of bond are
Ionic bond ( formed due to complete transfer of electron between atoms(
Covalent bond ( formed by mutual sharing of electron)
Metalic bond ( present in the metals due to mobile electrons)
1 B bond in CaO is ionic bond formation in attached image
1 C hydrogen bond with nitrogen is covelent NH3 ammonia is formed because a bond between two non metals is expected to be covalent

Explanation:
Answer: This looks tough
Explanation:
Methane(CH4) is a gas at room temperature, Methanol (CH3OH) is a liquid. Explain why using types of intermolecular forces present.
Explanation:
Methane is a gas at room temperature but methanol is a liquid because in methane there's London dispersion intermolecular force but in methanol there's H-bond and London dispersion force. H-bond is more stronger than London dispersion force. So, it increases the boiling point of methanol that's why methane is gas at room temperature due to weak attraction of London dispersion force and methanol is liquid.
Methanol has a higher boiling point than methane due to stronger intermolecular forces (IMFs), or attraction between individual molecules. This makes its molecules more difficult to separate, requiring more energy and resulting in a higher boiling point.
What are intermolecular forces?An intermolecular force is a force that mediates the interaction of molecules, including electromagnetic forces of attraction or repulsion that act between atoms and other types of neighboring particles, such as atoms or ions.
Intermolecular forces are classified into five types namely,
Ion-dipole forces.Ion-induced dipole forces.Dipole-dipole forces.Dipole-induced dipole forces.Induced dipole forces.Between ions and polar dipole molecules, ion-dipole forces exist.
Since of stronger intermolecular forces (IMFs), or attraction between individual molecules, methanol has a higher boiling point than methane.
This makes it more difficult to separate its molecules, requiring more energy and resulting in a higher boiling point.
Thus, this is the reason of using types of intermolecular forces present.
