WHILE ARRANGING THE ELEMENTS, NEWLAND OBSERVED THAT ORDER HE SET WERE LIKE NOTES REPRESENTED AS THE SIGNS,THAT IS, EVERY FIRST NOTE IS EQUAL TO THE EIGHT ELEMENT, BUT HE COULD FIND ONLY 58 ELEMENTS THAT WERE CORRECTLY ORDERED IN HIS TABLE
4.7 ft is equal to 55 in.
To find out how many inches are in 4.7 ft, you have to multiply 4x12 because there are 12 in in a ft. Since 4x12=48, just at the 7 in to 48 and you’ll get 55 in.
Answer:
32.8g/mole
Explanation:
Given parameters:
Mass of sample of gas = 32.8g
Volume = 22.4L
Unknown:
Molecular weight = ?
Solution:
To solve this problem we must understand that at rtp;
1 mole of gas occupies a volume of 22.4L
Number of mole of the gas = 1 mole
Now;
Mass = number of moles x molecular weight
molecular weight = = = 32.8g/mole
Answer:
An exothermic reaction is a chemical reaction in which less energy is needed to break bonds in the reactants than is released when new bonds form in the products. During an exothermic reaction, energy is constantly given off, often in the form of heat. All combustion reactions are exothermic reactions.
Explanation:
Matter cannot be created or destroyed.
The mass of the reactants in a chemical reaction will equal the mass of the products
Hope this helps :)
