Answer:
6 moles of C atoms, 12 moles of H atoms and 6 moles of O atoms
Explanation:
A chemical formula represents the number of moles of atoms presents in 1 mole of the compound.
For example, for 1 mole:
CₐHₓ, you have a moles of carbon and x moles of hydrogen.
Thus, for the molecule:
C₆H₁₂O₆, you have <em>6 moles of C atoms, 12 moles of H atoms and 6 moles of O atoms</em>
Answer:
V2= 531.4 ml
Explanation:
T1= 273+45 °C= 318 Kelvin
T2= 273+65 °C= 338 Kelvin
V1= 500ml *( 0.001L/1ml)= 0.5 Liters
V2=
=
= 0.5314465409 Liters* (1 ml/0.001 L)= 531.4 ml
Answers are:
1) The metals were not heated to 100°C.
2) The metals cooled before they were added to the water.
3) The thermometer was not completely submerged in the water while reading.
4) The calorimeter was not sealed properly, so heat escaped.
First Law of Thermodynamics - any heat lost by the system must be absorbed by the surroundings.
-qsystem = qsurroundings.
Heat spontaneously flows from a hotter (in this example hot metal) to a colder body (in this example water).
Student did not have mistake in determining the specific heat of metals, because there is heat lost during experiment.
Heat capacity of a sample is expressed in units of thermal energy per degree temperature (J/K).
Heat capacity is often defined relative to a unit of mass (J/kg·K or J/g·K), prefixed with the term specific.
For example, specific heat capacity of water is 4.184 J/g·K (Cp(H₂O) = 4.184 J/g·K).
The element to which this atom belongs is a p-block main-group element.
What is general electronic configuration?
Electronic configuration or general electron configuration or electronic structure of atoms or ions is the arrangement of orbital energy levels for s, p, d, and f-block elements of the periodic table.
Which group are p-block elements in the periodic table write the general electronic configuration of a p-block element?
Groups 13, 14, 15, 16, and 17 elements comprise the p-block elements. The general configuration of p-block elements is ns2np(1−6).
What is the general configuration of p- block elments?
The general electronic configuration of p-block elements is ns2np1-6 (Except Helium). The number of electrons in the p-block element's penultimate shell is either 2 or 8 or 18.
Therefore, the element belongs to the p-block.

Answer:
An object has potential energy (stored energy) when it is not in motion. Once a force has been applied or it begins to move the potential energy changes to kinetic energy (energy of motion).
Therefore, true. (Also would u mind giving brainliest, you don't have to hehe)
