Just add 273 to it. u'll get 288 kelvin =)
This layer<span> of the </span>earth<span> lies between the mantle and the solid inner core. It is the only liquid </span>layer<span>, a sea of </span>mostly iron and nickel about 1,400 miles. <span>The lava is </span>mostly made<span> up of iron and nickel</span><span>. The outer core creates the </span>Earth's<span> magnetic field. The final </span>layer<span> is the inner core, which is 900 miles deep. Scientists believe the inner core is a solid ball of iron and other minerals.</span>
Answer:
50 mg.
Explanation:
From the prescription, 240 ml amount is to be prepared containing 30 ml tussin syrup. As the frequency is 5 mL qid, it means 5mL of syrup is to be administered four times daily i.e. 20 mL daily. To calculate the amount of tussin taken daily,
<em> </em><em><u>30 mL tussin</u></em><em> = </em><em><u>X mL of tussin</u></em>
<em> 240 mL solution 20ml solution</em>
⇒ 2.5 mL of tussin
5 ml tussin contains 100mg guafenesin,
So,
⇒ 2.5 ml of tussin contains 100x2.5/5 = 50 mg guaifenesin
Explanation:
Ionization reactions are reactions that involve an electrically neutral atom or molecule be converted into electrically charged atom or molecule (ions).
Ions are recognized by the (⁺) and (⁻) signs.
First Reaction: Ions are formed so this option is correct.
Second Reaction: Ions are formed so this option is correct.
Third Reaction: This option is wrong. No ions are formed.
Fourth Reaction: Ions are formed so this option is correct.
Fifth Reaction: Ions are formed so this option is correct.
<span>Given in the question-
1 mole of cyclohexanol = > 1 mole of cyclohexene
Molar mass 100.16 g/mol
moles of cyclohexanol = .240 / 100.16= 0.002396 moles
Molar mass 82.143 g/mol
moles of cyclohexene formed @100 % yield = 0.002396
Molar mass 82.143 g/mol
mass of cyclohexene @ 100 % = .002396 x 82.143 = 0.197g
bur we have .138g
so % yield = .138 / .197 = 70.0 %
Ans- 70 percentage yield of cyclohexene.</span>
