Answer:
<h2>Digital thermometer are used these days instead of clinical thermometers because: Digital thermometers are designed to be more accurate. Most digital thermometers have digital screening which extract temperature of wherever you are measuring. </h2>
Answer:
64g of Oxygen
Explanation:
Firstly, carbon and oxygen react to form CO2 as follows;
C + O2 => CO2
According to the equation, one mole of C reacts with one mole of O2 to give one mole of CO2
Since molar mass of C= 12g/mol, O= 16g/mol
One mole of (C) contains 12g
One mole of O2 contains 16(2) = 32g
Hence, If there are 24g of C, there would be 24 × 32 / 12
= 768/12
= 64g
Hence, there would be 64g of oxygen if there are 24g of Carbon

Hey,
<h3><u>
QUESTION)</u></h3>
The mass of 6,022 × 10²³ molecules of a substance is called its molar mass.
- In fact this number represents the Avogadro Constant characteristic of the number of entities contained in a mole.
Fossil fuels + oxygen gas -------> carbon dioxide + water + heat
We calculate the molar mass of element X as follows:
No. of moles = 48/16 = 3.2 mol
Mass of X2 = 64.8 - 48 = 16.8 g
<span>2 molesX/5 mole O= x/ 3.00 moles O
</span>
x = <span>1.2 moles of X </span>
Molar mass = <span>16.8g/ 1.2 mol = 14 g/mol</span>
