Answer:
it can be referred to as heat energy
Answer:
16.6dL
Explanation:
First, we need to convert 1.66mL dL this can be achieved by doing the following:
1mL = 0.01dL
1.66mL = 1.66 x 0.01 = 0.0166dL
From the question, we were told that the volume 1 drop of blood = 1.66mL i.e 0.0166dL.
Therefore 1000 drops of blood will be = 0.0166 x 1000 = 16.6dL
When a gamma ray is emitted from the nucleus of an atom it reduces the overall energy of the nucleus. Emission of gamma rays almost happens along with beta and alpha emissions. After the two emissions, the nucleus of the atom would still be in an excited state. To achieve stability, gamma rays are emitted which will decrease the overall energy of the nucleus.
Answer:
the question you will write down is " how does gravity effect the toy car."
Explanation:
The amount, in liters, of the 0.2M NaCl solution required to measure out 3.0 grams of NaCl is 0.25 Liter.
<h3>Stoichiometric problem</h3>
Recall that the molarity of a solution is the ratio of the number of moles of solutes in the solution to the volume of the solution.
Molarity = number of moles/volume in Liters
Thus, a 0.2M NaCl solution contains 0.2 moles of NaCl in 1 Liter of the solution.
But 3.0 grams of NaCl is needed. Recall that:
Number of moles = mass/ molar mass
3.0 grams of NaCl = 3.0 grams/58.88 g/mole = 0.051 moles
If 1 Liter of the solution contains 0.2 moles of NaCl, then the amount of the solution that will contain 0.051 moles (3.0 grams) will be:
1 x 0.051/0.2 = 0.25 Liter
The volume of 0.2M NaCl solution required in order to measure out 3.0 grams of NaCl is 0.25 Liter.
