Finding neutrons = Mass number - proton number.
For finding neutrons for phosphorus = 31-15
=16.
Answer:
The answer to your question is:
Explanation:
Data
V = ?
mass = 3.46 kg
Density = 1116 kg/m³
Formula
density = mass / volume
volume = mass / density
Substitution
volume = 3.46 kg / 1116 kg/m³
volume = 0.0031 m³ = 3.1 liters
2 and 5 are features of sexual reproduction.
Explanation:
Expression for of the given reaction is as follows.
Let us assume that the concentration of given species is "s". As the value of is given as .
s =
Therefore, concentration of will be calculated as follows.
= 2s
=
= M
Now, we will calculate the value of as follows.
=
= 0.1535 V
Thus, we can conclude that the potential of given cell is 0.1535 V.
Answer:
B. 6.3 × 10² J
Explanation:
The formula for work (w) done is
w = f×d
f = 70 N
d = 10 m
w = 70 × 10
w = 700 J = 7 × 10² J
w is <em>positive</em> because work is being done on the object.
