The correct answer is: c) Co2+(aq) + Zn(NO3)2 (aq)
Precipitation reaction can be defined as the process of the formation of an insoluble salt. An insoluble salt is formed when two solutions containing soluble salts are combined (from its aqueous ions). precipitation reaction refers to the. The insoluble salt that falls out of solution is called precipitate
Answer:
What will happen to Uk if you double the mass?
Explanation:
Uk = 0.5 * m * v²
You see that both m and v are variable, which means that both m and v can be any number. Regardless of the numbers you put in for m or v, the formula to calculate the kinetic energy (Uk) remains valid.
You could ask
1. What will happen to Uk if you double the mass?
2. What will happen to Uk if you double the velocity?
please see and understand(!) that the relationship between Uk an v² is indeed the velocity squared....
EXTRA
Uk = 0.5 * m * (v)²
Suppose the m = 3kg and velocity = 5 m/s
What is the Uk?
Well if you know the formula you can use your calculator to find out:
Uk = 0.5 * m * (v)²
Uk = 0.5 * 3 * (5)²
Uk = 0.5 * 3 * 25
Uk = 37.5 kgm/s²
Again you ask what will happen to Uk if you double the velocity?
At first it was 5 m/s and now it doubles, which means it now has that value *2
The new velocity is 5 *2 = 10 m/s
Uk = 0.5 * m * (v)²
Uk = 0.5 * 3 * (10)²
Uk = 0.5 * 3 * 100
Uk = 150 kgm/s²
150 = 4 * 37.5
So now you see that if you double your velocity, the Uk will be 2² = 4 times as big !
Answer:
2N2+02>_2N20
Explanation:
u have to use rap formula
Answer:
It would be higher than expected.
Explanation:
Respiration quotient (RQ) may be defined as the quantity used for the representation of the basal metabolic rate. This mainly depends on the amount of the carbon dioxide.
The respiratory quotient represents the ratio of carbon dioxide eliminated with the amount of the oxygen consumed. During stress condition, the oxygen consumption of our body increase and more carbon dioxide is exhale out from the body. This will increase the RQ.
Thus, the answer is RQ will be higher than expected.
Answer:
The halogens located in group 17
Explanation:
The change in energy of a neutral atom when an electron is added is known as electron affinity. <em>Fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At) are known as halogens and conform the group 17 of the periodic table, the group that presents higher electron affinity.</em> This characteristic happens because of their atomic structures, it is easier for them to gain electrons because they are closer to form octets.
Here I present you halogens' electron affinities values:
- Fluorine (F) -328 kJ mol-1
- Chlorine (Cl) -349 kJ mol-1
- Bromine (Br) -324 kJ mol-1
- Iodine (I) -295 kJ mol-1
<em>The use of negative signs is to indicate the RELEASE of energy.</em>
I hope you find this information useful and interesting! Good luck!
