Answer:
las plantas
Explanation:
Las plantas son los seres vivos capaces de transformar energía luminosa utilizando agua y dióxido de carbono (CO₂) en energía química en forma de moléculas llamadas carbohidratos. El proceso a través del cual realizan esto se denomina fotosíntesis, y para ello requieren un pigmento de color verde denominado clorofila, el cual es necesario para captar la energía luminosa proveniente del Sol.
The Atomic number for the Element H is 1.
Hope this helps. :)
Answer:
True
Explanation:
A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Answer:
Silicon forms four covalent bonds with hydrogen. The formula of the compound is SiH4. Germanium forms four covalent bonds with chlorine, the formula of the compound is GeCl4
Explanation:
The outermost shell of group 14 elements contains four electrons, which can combine with four other atoms having one unpaired electron in their outermost shell to form four electron pairs or a complete octet as required by the octet rule.
Answer:
its mass
its temperature
Explanation:
The heat capacity of a body is the amount of heat needed to raise that temperature of a body by 1k or 1°C.
It is expresses as:
H = m c Ф
where m is the mass of the body
c is the specific heat of the body
Ф is the temperature change of the body
Specific heat capacity is that heat content needed to raise the temperature of a unit mass of a substance by 1k or 1°C
Heat capacity is also known as heat content;
To solve the problem:
since H = m c Ф
we make the unknown c the subject of the expression;
c = = H / mФ
So to obtain the specific heat capacity, divided the heat capacity by mass and its temperature change.
