is it six? like B?View attachment 62472 How do you even break this question down
Its sevenis it six? like B?
'Fun fact ' I actually forgot from which year i have sent thisis it six? like B?
its s14 p12 do you have more questions you want solved?'Fun fact ' I actually forgot from which year i have sent this
Any predictions ?its s14 p12 do you have more questions you want solved?
Are you kidding me....Any predictions ?
Maybe idk the prediction for physics practical was so accurate maybe you might know what might be the key questionAre you kidding me....
thank uuuQ15- Electronegativity increases across the period and so does first ionisation energy ( since atomic size decreases as nuclear charge increases)
So if you check the data booklet Mg has a higher first ionisation energy than Al so answer is B.
Is the answer o.425A chemist took 2.00dm3 of nitrogen gas, measured under room conditions, and reacted it with a large volume of hydrogen gas, in order to produce ammonia. Only 15.0% of the nitrogen gas reacted to produce ammonia. What mass of ammonia was formed?
A 0.213g
B 0.425g
C 1.42g
D 2.83g
pleaseee helpp urgentt!!!!
yes it is dear, thank u so muchIs the answer o.425
if it is then first find the moles of nitrogen gas then take 15% of the moles
then take mole ratio with ammonia produced that would be 1:2
then you can use the formula n=m/Mr to find the mass of ammonia produced
hahahatf is this

Question 3: first step to do is to balance the second equation with the first equation with equal electrons. Combine both the two equations and you will get B.9701_w13_qp_11 Q.3, 7, 11 plss.
