Use blue litmus paper. This is an indicator that can safely determine whether it is a base or an acid by changing color in response to the substance. This color indicates whether it is an acid or a base. Refer to the pH scale to see if the substance is basic or acidic.
Ratio is the relationship between two number indicating how many times the first number containing the second number.
The ratio of carbon to oxygen is as follows
0.429 :0.571
multiply 1000 to remove the decimals
therefore the ratio of mass of carbon to mass of oxygen =429:571
Answer:
168.0 g
Explanation:
First thing, write a balanced chemical equation:
n(H2SO4) = concentration * volume
= 1.0 M * 2.0 L
= 2.0 mol
According to the balanced equation, 1 mol of acid requires 2 mol of sodium bicarbonate. This means that 2 mol of acid requires 2 mol of sodium bicarbonate. What mass of sodium bicarbonate is this?
mass (NaHCO3) = number of moles * molar mass
= 2.0 mol * 84.0065 g/mol
= 168.0 g
Answer:
It is an saturated compound since there are no c-c double or tripple bonds.
Explanation:
If we had such double or tripple bonds the remaining o &H atoms cannot be accommodated to the carbon chain.
the carbon skeleton has (26×2)+6=58 valence electrons
O occupies 2 for each
18×2= 36
,58-36=22
only 22H can be directly bonded to the carbon skeleton.
remaining H= 14
therefore 7carbonyl carbon atoms will have to turn into carbinol carbon atoms .
so no space for c-c double bonds
If you use its electronic structure the last number should be a five so something like (2,5), (2,8,5) or (2,8,8,5) etc.
The elements therefore with 5 as it's final number and 5 on the outer orbit are N, P, As, Sb, Bi, Uup. Therefore with the answers given to you the answer is most likely 4) Phosphorus. <span />
