300 g of requires 30000 J of thermal energy to raise the temperature from 25 °C to 85 °C, what is the heat capacity of water? ANSWER ASAP PLEASE
According to the concept of specific heat capacity, the heat capacity of water is 1666.67 J/Kg°C.
What is specific heat capacity?Specific heat capacity is defined as the amount of energy required to raise the temperature of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.
It varies with temperature and is different for each state of matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.
It is given by the formula ,
Q=mcΔT
Substitution of values in the above equation, c=30000/0.3×(85-25)
c=1666.67 J/kg°C
Thus, the heat capacity of water is 1666.67 J/Kg°C.

What is the mass of the ethyl alcohol that exactly fills a 400.0 mL container? The density of ethyl alcohol is 0.789 g/mL.
Answer:
g = (0.789 g/mL) (200.0 mL) = 158
The mass of ethyl alcohol that exactly fills 400 ml of container is 315.6 grams.
How is mass related to density?Formula of density is given as , density =mass/volume
∴mass=density×volume
From the formula it is evident that density and mass are directly proportional while density and volume are inversely proportional.
From the given data, volume=400 ml and density =0.789 g/ml
∴by the formula,mass=density×volume
mass=0.789×400
mass=315.6 g
Mass and volume are extensive properties that depend on the amount of substance while density is an intensive property and does not depend on amount of substance.
Intensive properties are properties which are independent,wherein size of particles does not change.These properties cannot be easily computed and are not easily identifiable.

Having freckles (F) is dominant over not having freckles (f). A parent with freckles is crossed with a parent without freckles. The Punnett square shows the possible genotypes of the offspring.
What is the genotype of each square?
A: FF Ff ff
B: FF Ff ff
C: FF Ff ff
D: FF Ff ff
Answer:
A: Ff
B: ff
C: Ff
D: ff
Explanation:
You basically look at the box it's asking for, let's use A as an example. On the top where the A column is there's F, so that's one of the thingys I forgot what they're called. Next look at the row of A, and there's f. Put the 2 together and you get Ff. Reminder that any uppercase ones come first.
Hammer orchids are plants with flowers that are highly modified to resemble a female thynnid wasp (i.e., a wasp of the Thynnidae family) and can only be pollinated by thynnid wasps. Female thynnid wasps cannot fly, but males can. When the female is prepared to mate, she will climb up a tall plant or a blade of grass and wait for a male to appear. Males will pick up the female from her perch and mate with her in flight.
Given this information, in three to five sentences, describe these details:
one other feature of the hammer orchid that could attract its pollinator
how the orchid’s flower adaptation could lead to pollination
why you believe a plant would have more reproductive success with either a specialized pollinator or multiple pollinators

which of these pairs of atoms are isotopes
A: scandium-46, titanium-46
B: iron-56, sodium-24
C: chlorine-35, chlorine-37
D: sodium-24, magnesium-24
Taking into account the definition of isotopes, the correct answer is option C: chlorine-35, chlorine-37
First of all, all atoms are composed of a central nucleus in which there are positively charged particles, the protons, and neutrally charged particles, the neutrons, around which other negatively charged particles that are electrons move.
That is, atoms are made up of a nucleus (made up of protons and neutrons) and a shell made up of electrons.
On the other side, isotopes are atoms whose atomic nuclei have the same number of protons but different numbers of neutrons.
The atomic number (Z) indicates the total number of protons in the nucleus of a given atom, while the atomic mass (A) is obtained by adding the number of protons and neutrons in a given nucleus.
So, in other words, each isotope of the same element has the same atomic number (Z) but each has a different mass number (A). This means that the different isotopes of the same atom differ from each other only by the number of neutrons. So if a neutron is added to an atom, it becomes an isotope of that chemical element.
So, in this case, the correct answer is option C: chlorine-35, chlorine-37, because the two chlorine atoms correspond to the same element but have different atomic masses, whose values are 35 and 37.
