Answer:
The difference is 293.15 Kelvin.
Explanation:
Given data:
Temperature difference of matter = 20°C
Temperature difference of matter in kelvin = ?
Solution;
Formula:
0°C +273.15
now we will put the values instead of 0.
20°C + 273.15 = 293.15 K
Thus, the temperature difference between two sample is 293.15 K.
Answer:
<u>49 moles of atoms</u>
Explanation:
There are 7 individual atoms in each molecule of H2SO4: (2 hydrogens + 1 sulfur + 4 oxygens).
Therefore, if 7 moles are decomposed, there would be 7 times that amount of individual atoms:
7 x 7 = 49 moles of atoms
It has to be J. 12:00am cause at night that’s when everything
Answer is: c. CuSO4 + 2NaOH yields Cu(OH)2 + Na2SO4.
Copper atom has oxidation number +2, sulfur atom oxidation number +6, oxygen has oxidation number-2, sodium has oxidation number +1 and hydrogen has +1 on both side of chemical reaction, so elements did not change their oxidation numbers.
