Answer:
Test for carbon dioxide gas.
The reaction between baking soda and citric acid will form sodium ions, citric acid ions, carbon dioxide gas, and water. So all you have to do is add the gas produced (by gas displacement method or something) and test whether the gas is carbon dioxide, with lime water or other methods like hydrogencarbonate indicator. Hope this helped!
Explanation:
Think it though and always go back to the cause of the problem
When the speed of the particle is close to that of light, it's observed mass would be infinitely large.
To answer the question, we need to know what observed mass is.
<h3>What is observed mass in relativity?</h3>
This is the mass the body of an object in relativistic motion appears to have.
So, observed mass, m' = m/√(1 - β²) where
- m = rest mass and
- β = relative velocity of isotope to light.
Now, since the speed of the particle is close to that of light, β ≅ 1.
So, m' = m/√(1 - β²)
m' = m/√(1 - 1²)
m' = m/√(1 - 1)
m' = m/√0
m' = m/0
m' = ∞
So, when the speed of the particle is close to that of light, it's observed mass would be infinitely large.

Answer:
Global temperature of earth will increase
Explanation:
green house gases will trap. the heat and it will make our atmosphere warm.
Answer is: A. pure substance.
Pure substance is made of only one type of atom (chemical element) or only one type of molecule (chemical compound), it has definite and constant composition with distinct chemical properties.
Glucose is chemical compound composed of carbon, hydrogen and oxygen atoms connected with covalent bonds.
Pure substances can be separated chemically, not physically, that is difference between pure substances and mixtures.
