Can somebody please explain the heat formula to me? q=mcΔt
Thank you!!
Answer:
Explanation:
It describes how much heat must be added to a unit of mass of a given substance to raise its temperature by one degree Celsius. ... The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the equation: Q=mcΔT.
Answer:
The formula q=mcΔt explained below
Explanation:
so q represents the amount of heat energy. M is the mass of the object and c is the temperature of the object. Δt also known as delta is the change in temperature. It would be the final temperature minus the original temperature.

Definition of periodic trends
Use the information below to explain why the atomic radius decreases across a period.
Answer:
Detail is given below.
Explanation:
Atomic radius trend along period:
As we move from left to right across the periodic table the number of valance electrons increases. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.
we can see in picture A there is one positive charge and force of attraction is 2.30×10⁻⁸ N
In picture D there are 2 positive charge and force of attraction is 4.60×10⁻⁸ N
So by increasing the positive charge force of attraction also increases.
In F we can see there is more positive charge thus force of attraction is also greater.

the number of atoms in 2.0 moles of B is
Answer:
The answer is
1.204 × 10²⁴ atoms of BExplanation:
To find the number of entities of a substance given it's number of moles we use the formula
N = n × Lwhere n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
n = 2.0 moles
We have
N = 2 × 6.02 × 10²³
We have the final answer as
1.204 × 10²⁴ atoms of BHope this helps you
Number of moles of boron (B) = 2
To Find :We have to find number of atoms present in the given amount of boron[tex].[/tex]
Solution :➤ We know that 1 mole of substance contains 6.022×10²³ particles (atoms/molecules).
Avogadro's no. = 6.022 × 10²³★ Number of atoms present in B :
⭆ N = n × [tex]\sf{N_A}[/tex]
N denotes number of atomsn denotes mole number[tex]\sf{N_A}[/tex] denotes avogadro's number⭆ N = 2 × 6.022 × 10²³
⭆ N = 12.044 × 10²³
⭆ N = 1.2 × 10²⁴
Hope It Helps!
What is the relationship between a white dwarf and black dwarf?
Answer:
No longer emitting heat or light, the white dwarf will become a black dwarf. Because it emits no radiation, it is nearly impossible to see. However, the black dwarf would still retain its mass, allowing scientists to detect the effects produced by its gravitational field.
Explanation:
Answer:
white dwarfs are hot, black dwarfs are cold
Explanation:
a white dwarf is a slowly burning and aging corpse of a main sequence star such as our sun. they are up to 40 times hotter then the sun, ranking among one of the hottest objects in the universe, except their luminosity is so low that all their heat stays in them basically forever.
On the other hand, a black dwarf is a theoretical ending to a white dwarf, over the course of trillions of years, white dwarfs cool down into black dwarfs. black dwarfs rank among the coldest possible temperature. We aren't sure if these are really a thing, because we still haven't given white dwarfs enough time to cool down.
Mrs. K is trying to rearrange her living room. She uses 150 N of force to move a 600 g table. The table does not move. How much work is done?
90,000 J
4 J
600 J
0 J
Answer:
0J
Explanation:
Work = Force * Distance
Since the distance (or the displacement) in this problem is 0, hence, no work is done. W = 150*0 = 0. The mass of the object is just trying to trick you. Hopes this helps!

When you put water into a hot metal pan of equal mass, why does the pan cool down more than the water heats up ?
Answer:
The specific heat of water is greater than that of the metal
Explanation:
When water is put into a hot metal pan of equal mass, we discover that the pan cools down more than the water heats up because heat is rapidly transferred from the pan to the water.
This happens because the specific heat capacity of water is much greater than that of the pan hence heat is more quickly transferred from the pan to the water.

Answer:
B) Ca(H2PO4)2
Explanation:
To solve this we must be knowing each and every concept related to chemical formula. Therefore, the correct option is option B among all the given options.
What is chemical formula?The chemical formula is indeed a means of expressing information about just the chemical proportion of atoms that comprise a certain chemical compound as well as molecule through the use of chemical element numbers and symbols.
Furthermore, the molecular formula does not contain any words and does not serve as a chemical name. However, it just indicates basic chemical structures and is not the same as the entire chemical structural formula. The correct formula for calcium dihydrogen phosphate is Ca(H[tex]_2[/tex]PO[tex]_4[/tex])[tex]_2[/tex].
Therefore, the correct option is option B among all the given options.
