Answer:
it's a metel
Explanation:
as far as it can conduct electricity.
it's not a metal if it can't except it it's a metalloids
Answer:
The correct option is: a chemical reaction between carbohydrates and oxygen to produce carbon dioxide, water, and heat energy
Explanation:
Respiration refers to the catabolic reactions in the cells that produce energy in the form of adenosine triphosphate (ATP) from various nutrients.
An aerobic respiration, is a spontaneous process that involves the use of <u>molecular oxygen (O₂) to produce energy (ATP). In this process, molecular oxygen oxidizes nutrients such as carbohydrates, fats, and proteins; to give carbon dioxide, water and heat energy</u>.
4157 J work is done by the gas , If 2 moles of helium undergo a temperature increase of 100 K at constant pressure.
<h3>What are Noble Gases ?</h3>
The noble gases are helium, argon, krypton, xenon, and radon, in order of their mass.
They are called noble gases because they are so majestic that they do not react with anything in general.
The work done can be calculated by the formula
Q=n Cp ΔT
Cp= ( 1+ f/2)R
R= 8.3144598 J. mol-1.
Cp = (1+3/2) * 8.314
Cp = 5*8.314/2
Q= 2 * 5 *8.314 *100/2
Q = 4157 J
Therefore 4157 J work is done by the gas , If 2 moles of helium undergo a temperature increase of 100 K at constant pressure.

Answer:
Electric power circuits, appliances and lights
Explanation:
3.4 mol HCl * ( 36.46 g / 1 mol ) = 123.964 g HCl = 1.2 x 10^2 g HCl
Convert moles of HCl to grams of HCl using the molar mass ( 36.46 g/mol ).
Revise your answer to have the right number of significant figures ( 2 significant figures in this case, as determined by the the number of figures in the value with the least figures).
