Answer: The molarity of this solution is 0.159 M.
Explanation:
Given: Mass of solute = 16.3 g
Volume = 1.75 L
Number of moles is defined as the mass of substance divided by its molar mass.
Hence, moles of NaCl (molar mass = 58.44 g/mol) ar calculated as follows.
Molarity is the number of moles of a substance present in a liter of solution.
So, molarity of the given solution is calculated as follows.
Thus, we can conclude that the molarity of this solution is 0.159 M.
False, because heat travels from warm to cool objects, so if both have the same temp ( ie: no temp difference) heat will not be transferred between them.
Answer:
-- 5.8×10⁻⁹ of the H is in 2P states at T=5900 K, a typical Sun surface temperature.
-- 3.3×10⁻¹² of the H is in 2P states at T=4300 K, a typical Sunspot temperature.
Explanation:
<u>Answer: </u>The reaction between iodine and strontium is less reactive than the reaction of bromine and strontium.
<u>Explanation:</u>
Iodine and bromine belong to the same group which is Group 17 of the periodic table. Iodine lies in Period 5 and bromine lies in Period 4.
Reactivity of non-metals is defined as the tendency of the elements to gain electrons easily. This depends on the electronegativity values. More the electronegativity, more will be the reactivity and vice-versa.
Reactivity of non-metals decreases from moving down the group and increases across the period.
The electronegativity of iodine is less than bromine. Hence, it is less reactive than the bromine.
The reaction between strontium and bromine is more favorable because it is the reaction between two reactive elements.
Hence, the reaction between iodine and strontium is less reactive than the reaction of bromine and strontium.
Answer:
Explanation:
Given
Required
Determine the final mass
First we need to determine the total mass after the sample mass is added to an additional sample;
Next, divide the total mass by 3
The final mass is calculated as follows;
<em>Hence, the final mass is 17.560943085g</em>
