Explanation:
XO3
X + 3x16 = 80
x= 32 atomic mass for sulfur
SO3
Proton—positive; electron<span>—negative; neutron—no charge. The charge on the proton and </span>electron<span> are the same size but opposite. The same number of protons and </span>electrons<span> exactly cancel one another in a neutral atom.</span>
Answer:
Burning Paper
Explanation:
Burning Paper is an example of a chemical change because;
- A new substance called ''Ash'' is formed.
- It is an irreversible reaction.
From Boyle's law, we can use the equation
P1V1 = P2V2
to find the volume when the pressure is increased to 760 kPa:
V2 = P1V1 / P2
V2 = (210 kPa)(15.0 L) / 760 kPa
V2 = 4.14 Liters
Therefore, the volume is 3.99 Liters after the pressure increased to 760 kPa.
But if the pressure is increased to 790 kPa, the volume of the krypton will decrease to
V2 = P1V1 / P2
V2 = (210 kPa)(15.0 L) / 790 kPa
V2 = 3.99 Liters
Find the mode of the set of data: 55, 56, 45, 51, 60, 53, 63, 70, 62, 58, 63
kirill [66]
Answer:
the mode it is 63
Explanation:
put the numbers from least to greatest and whatever number appears more than one time is the mode in the problem .
