Answer:
This is and ADDITION REACTION
Explanation:
Because your putting a compound and an element together
The correct answer is<span> C) Water takes long to heat and cool down than other liquids.
It doesn't climb up the sides of a tube any more than other solutions do, and being a universal solvent has nothing to do with radiators. It does however take a long time to heat and cool down since you don't have a 100+ celsius burner to heat it up in an instant.</span>
Answer
find out the number of moles and use the molar ratio (numbers in front of formulas (in this case they are all 1) to determine how many moles of each product you are going to get theoretically
n=m/M is the equation to use to get moles here
30.8 gm/32.04 g/mol=0.9612 moles of the methanol and also of the formaldehyde so
0.9612 moles of the formaldehyde x molar mass (M) 30.73 g/mol= 29.54 gm which is the theoretical yield you already have the actual yield of 24.7 gm
then divide the actual by the theoretical to get the % yield which is 83.6%

Answer:
In atomic physics and quantum chemistry , the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s 2 2s 2 2p 6, using the notation explained below.

<u>Answer:</u> The partial pressure of helium gas is 0.80 atm
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the partial pressure of helium gas, we use the law given by Dalton, which is:
We are given:
Total pressure of the cylinder, 
= 1.00 atm
Vapor pressure of oxygen gas, 
= 0.20 atm
Putting values in above equation, we get:
Hence, the partial pressure of helium gas is 0.80 atm
