According to the stoichiometry the CO2 formed is 1/2 the moles of H2O. So take the moles of CO2 as 5moles.
n=m/M
Where :
n = mole
m = mass
M = molar mass
Molar mass of CO2 = 44gmol^-1
Therefore mass = 5mol× 44gmol^-1= 220g
A) would be correct.
The moon is right next to Earth.
Earth orbits around the sun.
Our solar system is at the edge of the Milky Way. So the edge of the Milky Way would be nearer than the center.
B. Another team of scientists must be able to replicate the results of
the experiment.
Explanation:
Scientists follow due scientific processes in supporting a claim. This process is known as scientific method. A scientific method is a procedural way of investigating an observation. It entails:
- careful observation and measurement
- detailed experiment
- the formulation, testing, and modification of hypotheses
Through this, when a finding is made, before it can be acceptable by the scientific community, it must be tested through a series of experiments by other scientist. These scientists will also test for the validity of the claim that a new element has been discovered.

An element but I’m not too sure
Answer: option (1) decreases.
Explanation:
May be you have experienced that: when you go to the beach, where the atmposhpere pressure is greater than the atmosphere pressure in places that are at higher altitudes, the water takes longer to boil. That is because the boiling temperature is greater, and you need more total heat (more time) to permit the liquid to reach that temperature.
The reason why that happens is because substances boil when the vapor pressure (the pressure of the particles of vapor over the liquid) equals the atmosphere pressure. So, when the atmposhere pressure increases, the temperature at which the vapor pressure reaches the atmosphere pressure also increases, and when the atmosphere pressure decreases, the temperature at which the vapor pressure reaches the atmosphere pressure decreases.
