Answer:
ATP
Explanation:
it is made by breaking glucose down
Answer:
Once the last phosphate group is removed from the ATP molecule by hydrolysis, it will form ADP plus inorganic phosphate. ADP is a lower energy molecule. The release of energy during hydrolysis of ATP can be harnessed by the cell to do work. Living things continuously use ATP but it is renewable and can be recycled.

A scientist claimed that he radiocarbon dated a fossilized skull of a dinosaur and found it to be about 63 million years old. Do you support his claim? Provide at least one scientifically based reason why you do or do not support the claim.
Answer:Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some could tolerate. After the AOGS-AGU conference in Singapore, the abstract was removed from the conference website by two chairmen because they could not accept the findings. Unwilling to challenge the data openly, they erased the report from public view without a word to the authors. When the authors inquired, they received this letter:

A radioactive element having and atomic number 82 and atomic mass 214 emits a beta particle. The resulting element is:______.
Answer:
[tex]\frac{214}{83} Bi[/tex]
Explanation:
In beta emission, a neutron is converted into a proton thereby reducing the neutron:proton (N/P) ratio.
When a beta emission occurs, the mass number remains the same while the nuclear charge increases by one unit. The daughter nucleus is found one place to the right of its parent in the periodic table.
A motorist discovers that her auto tire measures 29.2 psi rather than the recommended 35 psi. If the tire’s volume is assumed constant at 11.6 L and the temperature is 45F at the filling station, how many moles of air will the motorist need to add to bring the tire to 35 psi? (assume 1.00 atm = 14.7 psi)
Answer:
0.20 moles
Explanation:
The pressure is proportional to the quantity of gas at a given temperature and volume. So, the quantity needs to be increased by a factor of ...
(35 psi)/(29.2 psi) = 175/146 ≈ 1.19863
The fractional increase required is ...
1.19863 -1 = 0.19863
__
The quantity of air currently in the tire is ...
1 mol·519.67°R/(atm·23.6442 L) × (29.2/14.7 atm) × (11.6 L) / (45+459.67)°R
= 1.0035 mol
so we need to add ...
(fraction to add) × (current quantity) = amount to add
0.19863 × 1.0035 mol = 0.1993 mol = amount to add
About 0.20 moles of air must be added to the tire to bring the pressure up.
why is more dew formed on a grass and not on polished metal surface
Answer
Incidentally, they all form dew but because grass is closer to the soil, which maintains heat longer than the air where tree leaves are found, you will find more condensation in that region. Also, higher up the wind and sun will allow faster evaporation which makes the dew less noticable on tree leaves.
Explanation:
Preferred objects of dew formation are thus poor conducting or well isolated from the ground, and non-metallic, while shiny metal coated surfaces are poor infrared radiators. ... If the wet soil beneath is the major source of vapor, however (this type of dew formation is called distillation), wind always seems adverse.
If the specific heat of water is 4.18 3/g*^ C much heat is required to increase the temperature of 12 g of water from 23 degrees * C to 39 degrees * C ^ 2
Answer:
Q = 802.6 J
Explanation:
Given data:
Specific heat capacity of water = 4.18 J/g.°C
Mass of water = 12 g
Initial temperature = 23°C
Final temperature = 39°C
Heat required = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 39°C - 23°C
ΔT = 16 °C
Q = 12 g× 4.18 J/g.°C × 16 °C
Q = 802.6 J
1. What is a wave?
a.) a vibrating disturbance that transfers energy from place to place
b.) a material which a wave travels through
c.) an area where coils spread out
d.) the maximum distance a medium moves from its rest position
Answer:
A.
Explanation:
A wave is a disturbance that moves energy from one place to another. Only energy — not matter — is transferred as a wave moves. The substance that a wave moves through is called the medium. That medium moves back and forth repeatedly, returning to its original position. But the wave travels along the medium

Answer:
Of course, what we today call atoms can be divided into more elementary particles, but not that many.

The formula for calculating power is work divided by time (power = work + time). What are two ways of stating the same relationship?
work = power + time
nwork s power x time
power
time = work x power
Opower workx time
time
Work
Answer:
See the answer below
Explanation:
The formula for calculating power is such that;
power = work/time
Two ways to restate the relationship between the 3 variables would be to make time and work the subject of the formula respectively.
1. When time if made the subject of the formula;
time = work/time
2. When work is made the subject of the formula;
work = power x time
Reacting 10.0 mL of H2(g) with 10.0 mL of C2H4(g) produces 10.0 mL of C2H6 at 1.5 atm. If the reaction produces 3.1 kJ of heat and the decrease in volume requires the heat surroundings do 7.6 J of work on the gases, what is the change in internal energy of the gases?
Answer:
the change in internal energy of the gases is -3.0924 KJ
Explanation:
The computation of the change in internal energy of the gases is as follows;
Given that
Q = -3.1 KJ
= -3100 J
It is negative as the heat is lost from the mixture
And,
W = + 7.6 J
It is positive as the work is done in the mixture
Now we use the following equation
Delat E = Q + W
= -3100 J + 7.6 J
= -3092.4 J
= -3.0924 KJ
Hence, the change in internal energy of the gases is -3.0924 KJ

what change in the system will increase the boiling point
Answer:
ExplanationIt is moving from 4s to 8s at a constant speed of 4 cm:
Answer:
Boiling points increase as the number of carbons is increased.
Explanation:
The addition of solutes or other substances usually changes the boiling point. Additionally, changing the pressure on a liquid changes its boiling point. Sugar, salt or other non-volatile solutes in water will usually make the boiling point higher.
The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. The influence of each of these attractive forces will depend on the functional groups present. Boiling points increase as the number of carbons is increased.

Which of the following best describes foliated metamorphic rocks?
A
There are easily recognizable fossils.
B
The rock has ribbon-like layers of bands.
C
They have crystals like igneous rocks.
D
Different sized sediments can be seen.
Answer:
It's C because Metamorphic rocks were once igneous rocks. And, because Gneiss which is a Metamorphic rock has crystals inside of it.
Different rock types appear during rock formation. The best description of foliated metamorphic rocks is that;
B . The rock has ribbon-like layers of bands.Due to the pressure and heat that is exerted on some rock types, there is an alignment or foliation of rocks. The appearance can be described as ribbon-like.
The examples of rocks that fall under this classification are slate, phyllite, gneiss, and schist.
The non-foliated rocks do not show any alignment in their minerals. Examples are; quartzite, marble, and novaculite.
Summarily, option B best describes a foliated metamorphic rock.

The volume of a gas with an initial pressure of 380 mmHg atm increases from 5.0 L to 8.0 L. What is the final pressure of the gas, in atm, assuming no change in moles or temperature?
A) 238 atm
B) 2.4 atm
C) 0.31 atm
D) 0.80 atm
E) 8.0 atm
Answer:
0.31 atmExplanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new pressure
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
From the question
760 mmHg = 1 atm
380 mmHg = 0.5 atm
We have
[tex]P_2 = \frac{0.5 \times 5}{8} \\ = 0.3125[/tex]
We have the final answer as
0.31 atmHope this helps you

2. What kinds of non-metals are REALLY reactive? why?
3. What group on the periodic table doesn’t react at all? why?
Answer:
1. Alkali metals (group 1)
2. halogens (Group 17)
3. noble gasses (group 18)
Explanation:
1. alkali metals only have one valence electron meaning that they really want to lose that one valence electron to get a full octet.
2. halogens have 7 valence electrons meaning that they just need to gain 1 to get a full octet.
3. Nobel gasses already have a full octet meaning that they don't want to react. (atoms only react to get a full octet)
