Answer:
Explanation:
Hello,
In this case, since the undergoing chemical reaction is:
The corresponding moles of carbon dioxide occupying 40.0 mL (0.0400 L) are computed by using the ideal gas equation at 273.15 K and 1.00 atm (STP) as follows:
Then, since the mole ratio between carbon dioxide and calcium carbonate is 1:1 and the molar mass of the reactant is 100 g/mol, the mass that yields such volume turns out:
Regards.
Answer:
Output voltage = 600 V
Explanation:
Using the transformer equation which simply states that the ratio of the secondary to primary voltages in a transformer equals the ratio of the number of loops in their coils.
Number of input turns/Number of output turns = Voltage of input/voltage of output
10/50 = 120V/voltage of output
Voltage of output = 120 V/0.2
Voltage of output = 600 V
Answer:
The answer to your question is letter d
Explanation:
If we remember there is a limit of electrons that can be place in a sublevel
Sublevel s only accept 2 electrons
Sublevel p only accept 6 electrons
Sublevel d only accept 10 electrons
Sublevel f only accept 14 electrons
This is in agreement wth the levels of energy, that only accept a determine number of electrons
Level Sublevel # of electrons
1 s 2
2 s and p 8 (2 + 6)
3 s, p and d 18 (2+6+10)
4 s, p, d, f 32 (2+6+10+14)
5 s, p, d,f 32 (2+6+10+14)
6 s, p, d 18 (2+6+10)
7 s, p 8 (2+6)
All you need to do is to look at both sides of the equation and see who has the same element, state, coefficient, and charge and those will be your spectator ions.
In this question, the spectator ions would be 
and 
.
